Technical SEO & Indexation

  1. How would you handle crawl budget optimization for a job portal with millions of dynamically generated job listings?

    Answer: Managing crawl budget starts with prioritizing important URLs and eliminating waste. On a job portal, not all pages deserve equal crawl frequency. I start with log file analysis (using JetOctopus or Screaming Frog Log Analyzer) to find URLs that are being crawled frequently but shouldn’t be — like expired jobs or parameter-based duplicates.

    Real Example: For one portal, we noticed Googlebot wasting 30% of its crawl on expired jobs. We implemented meta noindex on expired listings for 30 days, followed by a 410 Gone status. This reduced crawl bloat and helped important pages get crawled more often, improving freshness in SERPs.

  2. What’s your approach to managing expired job pages? How do you decide between using 410, 404, or 301?

    Answer: The key is to balance user experience and index hygiene. I apply a 3-step rule:

    • Phase 1: Add noindex tag but keep the page live with a message: “This job has expired, but check similar jobs below.”

    • Phase 2: After 30–60 days, return a 410 Gone status if the job won’t return.

    • Phase 3: Where appropriate, use a 301 redirect to a relevant category or location page.

    Example: A job post for a software engineer in Bangalore that expired was redirected to the parent page /jobs/software-engineer/bangalore/, retaining some link equity and improving user navigation.

  3. How do you prevent duplicate content issues across similar job postings (e.g., same job title in multiple locations)?

    Answer: Duplicate content is common in job portals — especially for the same job title across locations or slight description variations.

    Solutions:

    • Implement canonical tags on similar job variants.

    • Use unique job IDs in URLs.

    • Dynamically vary meta tags and intros per location.

    • Group highly similar jobs and present them as a single listing with selectable locations.

    Example: Instead of 10 pages for “Customer Support Executive – Delhi/Mumbai/Bangalore,” we created a single page with location tabs — dramatically reducing duplication.

  4. How do you implement and maintain a scalable sitemap strategy for millions of listings?

    Answer: Use a dynamic sitemap generator that:

    • Segments sitemaps by category, location, or date.

    • Auto-updates daily with fresh job listings.

    • Limits each sitemap to 50,000 URLs and links all via an index sitemap.

    Example: For a site with 2M listings, we created category-wise sitemaps like /sitemaps/developer-jobs.xml, each auto-updated every 6 hours.

    • Load them dynamically using AJAX or JS pushState so that the URL changes, but no new page is loaded or indexed.

    • Canonical remains untouched to the main job or listing page.

      6. Explain how canonicalization should be handled for job listing URLs with tracking parameters or filters.

      canonicalization for job listing URLs is critical for job portals because of how easily they can generate URL variants through filters, tracking parameters, or duplicate content across locations and categories.


      1. What’s the Problem?

      Job portals often generate multiple URLs for the same job, such as:

      • example.com/jobs/software-engineer-12345

      • example.com/jobs/software-engineer-12345?utm_source=linkedin

      • example.com/jobs/software-engineer-12345?ref=home&sort=date

      • example.com/jobs/software-engineer-12345?location=bangalore

      These URLs all lead to the same job listing, but from Google’s eyes, they’re different pages — causing:

      • Duplicate content

      • Wasted crawl budget

      • Diluted link equity

      • Canonical confusion


      2. How Canonicalization Fixes It

      You use the <link rel="canonical"> tag to signal to Google which version of the URL is the master (canonical) version.

      Example for any variant of the above URLs:

      <link rel=”canonical” href=”https://example.com/jobs/software-engineer-12345″ />

      This tells Google:

      “Hey, no matter what tracking or filters are added, this is the authoritative URL you should index and rank.”


      3. Best Practices for Job Portals
      🔸 Choose a clean, parameter-free canonical URL
      • Strip out UTM codes, filters, and session IDs

      • Keep only the core, SEO-friendly URL

      🔸 Ensure self-referencing canonical on the canonical page itself
      • The base job page should point to itself:

      <link rel=”canonical” href=”https://example.com/jobs/software-engineer-12345″ />
      🔸 Use server-side canonical tags when possible
      • Especially if you serve pages via dynamic JavaScript. Rendered canonicals are often delayed or skipped.

      🔸 Avoid conflicting signals
      • If your canonical says one thing but sitemap or internal links say another, Google may ignore the canonical.

      • Ensure sitemaps contain only canonical URLs.


      4. Real Example

      Before Fix:
      A job post had 12 URL variants from ads, internal filters, and partner referrals. None had canonical tags. Google indexed 7 versions, all with fragmented link equity.

      Fix:

      • Added canonical to the clean URL.

      • Used parameter handling in GSC to mark utm_, ref, sort as non-influential.

      • Added a filter on the server to always render the canonical tag server-side.

      Result:

      • Index bloat reduced by 60% in 3 weeks.

      • Rankings stabilized to the correct version.

      • Referral traffic tracking still worked fine (analytics uses full URL).


      Bonus Tip: Handle Filters via AJAX or PushState

      If you’re using filters like salary range or job type: 

  5. What role does structured data play for job portals? How do you ensure your JobPosting schema is compliant and effective?

    Answer: I implement JobPosting schema with required fields (title, description, datePosted, validThrough, jobLocation, hiringOrganization, employmentType) and enrich it with baseSalary, jobBenefits, and applicantLocationRequirements.

    Example: For remote jobs, we use "jobLocationType": "TELECOMMUTE". After implementation, CTR from Google Jobs increased by 18% within 4 weeks. 

  6. What is the impact of thin content in job listings, and how would you resolve it at scale?

    Answer: I focus on enhancing listings with value:

    • Add structured bullet points for roles/responsibilities.

    • Include company-specific details (culture, mission).

    • Auto-embed related FAQs or career tips below listings.

    Example: We added auto-generated FAQs based on job titles using OpenAI and schema, which boosted engagement metrics and lowered bounce rate.

  7. How do you use log file analysis to improve crawl efficiency on a job portal?

    Answer: I use log files to answer questions like:

    • What % of Googlebot hits are on expired or low-priority pages?

    • Are important pages getting crawled daily or weekly?

    Toolset: JetOctopus, Screaming Frog Log Analyzer, or BigQuery.

    Example: Found that Googlebot wasn’t crawling new listings fast enough. Added them to sitemap.xml, linked them from the homepage, and crawls increased by 40% in 7 days. 


🧱 On-Page SEO & Architecture
  1. How would you structure URL architecture for a job portal? Would you use parameters, subfolders, or subdomains? Why?

    Structuring the URL architecture of a job portal is crucial for SEO scalability, crawl efficiency, user experience, and long-term content management. Let’s break this down with a clear, human-touch explanation and real-world logic:


    Recommended Structure: Use Clean, Subfolder-Based URLs
    📦 Why Subfolders over Parameters or Subdomains?
    OptionSEO ImpactBest Use Case
    Subfolders✅ Most SEO-friendlyOrganizing job categories, locations, companies
    Parameters⚠️ Risk of duplicationTracking, filters (should be noindexed/canonical)
    Subdomains⚠️ Treated as separate sitesOnly if multi-brand or multi-country
    Ideal URL Structure for a Job Portal

    Here’s a clean, scalable way to design URLs:

    example.com/jobs/
    example.com/jobs/software-engineer/
    example.com/jobs/software-engineer/bangalore/
    example.com/jobs/software-engineer/bangalore/company-name/
    example.com/jobs/software-engineer-12345/ ← Job Detail Page

    Explanation of Each Level
    1. /jobs/
    • Hub for all listings.

    • Internally linked from home, includes featured roles.

    2. /jobs/software-engineer/
    • Category landing page.

    • Targeting keywords like “Software Engineer Jobs”.

    3. /jobs/software-engineer/bangalore/
    • Location + category combo.

    • Long-tail search: “Software Engineer Jobs in Bangalore”.

    4. /jobs/software-engineer/bangalore/company-name/
    • Employer-specific listings.

    • Good for employer branding and E-E-A-T.

    5. /jobs/software-engineer-12345/
    • Actual job listing with a unique slug/ID.

    • URL slug can be generated from title + job ID to avoid conflicts.


    ⚙️ What to Avoid
    ❌ URL Parameters for Indexable Pages
    • URLs like example.com/jobs?role=engineer&location=bangalore are bad for SEO if indexed.

    • Use parameters only for filters or tracking — and canonicalize to the clean version.

    ❌ Subdomains (e.g., jobs.example.com)
    • They dilute domain authority and complicate analytics.

    • Only use subdomains when you truly need to separate ecosystems (e.g., international sites with different CMSs or teams).


    Bonus Enhancements
    • Slug Cleanup: Auto-generate slugs but limit to 60 characters max.

  2. How do you decide which job pages should be indexed and which shouldn’t?

    Deciding which job pages to index (and which not to) is one of the most strategic SEO decisions for a job portal — especially when you’re dealing with millions of listings, high turnover, and thin or duplicate content risks.


    Step-by-Step: How to Decide What Should Be Indexed

    🔹 1. Index Only Unique, Valuable, and Active Listings

    Should Be Indexed:

    • Live jobs that are still accepting applications

    • Listings with unique titles, descriptions, locations, and company info

    • High-volume or long-tail searches (e.g., “remote React developer jobs USA”)

    • Jobs with good internal linking or external backlinks

    Should Not Be Indexed:

    • Expired or closed job listings

    • Duplicates (e.g., same job across multiple locations with no content variation)

    • Listings with low or no traffic, high bounce, or high exit rates

    • Jobs with poor or auto-generated content (e.g., “Job 12345, posted by Company XYZ”)


    🔹 2. Use These SEO Tools & Metrics to Guide Indexing Decisions
    Tool/MetricUse It To Identify…
    Google Search ConsolePages with low impressions/clicks
    Log File AnalysisPages rarely or never crawled
    Screaming Frog/JetOctopusThin content or duplicate meta tags/titles
    Google AnalyticsPages with high bounce/exit rates
    3. Implement Indexing Controls

    ✅ For Indexable Pages:

    • Unique, meaningful content (not just job title + location)

    • Clear <title> and <meta description>

    • Schema markup (JobPosting)

    • Internal linking (from category/location pages)

    ❌ For Non-Indexable Pages:

    • Add <meta name=\"robots\" content=\"noindex, follow\">

    • OR return 410 Gone (for deleted jobs)

    • OR use canonical tag to point to the master page


    🧩 Real-World Example:

    Scenario: A job portal had 2M listings, but ~700K were expired or low value.
    Action Taken:

    • Used logic to mark expired jobs as noindex after 30 days.

    • Identified low-performing duplicates using GSC + log files.

    • Implemented canonical for similar jobs across multiple cities.

    Result:

    • Indexed pages dropped to ~1.3M

    • Crawl rate to important pages increased

    • Organic traffic grew 18% in 6 weeks


    Bonus Tip: Automate the Indexing Workflow

    Use logic like this in your CMS or backend:

    IF job_status = ‘expired’ AND days_since_post > 30
    THEN meta_robots = ‘noindex’
    ELSE IF job_content_score < threshold
    THEN meta_robots = ‘noindex’
    ELSE
    meta_robots = ‘index’

    You can also layer this with server-side 410 after 60–90 days of expiration for SEO hygiene.
    RuleAction
    Expired job?Noindex or 410
    Low traffic or duplicate content?Noindex or Canonical
    Unique, active, and high-quality?Index
    Parameter-based page or filters?Noindex + Canonical

     

  3. What’s your approach to internal linking across millions of job listings and category pages?

    Answer: We create contextual linking between:

    • Job listings and their category/location pages.

    • Related jobs (e.g., “More ReactJS Jobs in Bangalore”) within each listing.

    • Career blog articles linking to relevant job searches.

    Example: Internal links from blog posts like “How to Become a UI Developer” to matching listings improved page depth and time on site.

  4. How do you ensure location + category targeting (e.g., “Digital Marketing Jobs in Bangalore”) is SEO-optimized without creating keyword cannibalization?

    location + category targeting (e.g., “Digital Marketing Jobs in Bangalore”) is critical for job portals, but if not done right, it leads to keyword cannibalization, duplicate content, and ranking confusion.

    ✅ What is Keyword Cannibalization in Job Portals?

    It happens when multiple pages target the same keyword intent (e.g., you have 5 pages all trying to rank for “digital marketing jobs in Bangalore”).

    Result? Google doesn’t know which one to rank, and your authority gets split across pages.


    🧩 1. Define a Clear URL + Content Strategy

    ✅ Structure URLs Hierarchically and Uniquely:

    /jobs/digital-marketing/ → National category page
    /jobs/digital-marketing/bangalore/ → City-specific category page
    /jobs/digital-marketing/bangalore/company-name/ → City + employer page
    /jobs/digital-marketing-bangalore-12345/ → Job detail page

    Each URL serves a unique search intent, so no two pages compete.

    2. Create Differentiated, Location-Optimized Content
    🔍 Instead of duplicate text, localize it:

    ✅ Good example for /jobs/digital-marketing/bangalore/:

    Looking for digital marketing jobs in Bangalore? Explore top roles in SEO, SEM, content marketing, and social media across startups and MNCs like [Company A] and [Company B]. Average salaries in Bangalore range from ₹4L–₹10L for mid-level roles.

    Repeat this for each city, even if using templates — always inject:

    • City-specific employer names

    • Local job market stats

    • Unique meta title & description

    • Internal links to related jobs or companies


    🧩 3. Avoid Thin or Empty Pages

    Don’t auto-create location pages unless there are enough jobs to support that page.

    Use automation rules like:

    • Only create /jobs/role/city/ if there are at least 5 live jobs in that combination.

    • Else, redirect to broader category: /jobs/role/


    🧩 4. Use Canonicals and Noindex Tags Smartly
    If you do have multiple pages that overlap (e.g., /jobs/marketing/bangalore/ and /jobs/bangalore/marketing/):
    • Choose a primary version

    • Canonicalize others to the main one

    <link rel=”canonical” href=”https://example.com/jobs/digital-marketing/bangalore/” />
    If city-category combinations are auto-generated and empty:
    <meta name=”robots” content=”noindex, follow”>

    5. Optimize Internal Linking Hierarchy

    Make sure your internal linking structure reinforces hierarchy:

    • /jobs/digital-marketing/ → links to top cities like /jobs/digital-marketing/bangalore/, /mumbai/

    • City pages → link to job listings and company-specific roles

    • Avoid linking multiple pages with the same anchor text like “Digital Marketing Jobs” unless they point to different intents

    6. Use Structured Data to Distinguish Pages

    Implement JobPosting, Breadcrumb, and Organization schema on:

    • Listing pages (ItemList)

    • Job details (with city, employer, job type)

    • Breadcrumbs for hierarchy clarity in SERPs

    Real-World Example:

    A job portal had 1200+ city+category URLs — many had no jobs or just copied text.

    Fixes Applied:

    • Created dynamic rules to only generate pages with >5 jobs

    • Localized content using top employers and salary insights

    • Canonicalized duplicates

    • Rewrote meta tags with city- and role-based keywords

    • Internal linking improved to emphasize hierarchy

    Results:

    • Organic traffic to city-category pages ↑ 38% in 3 months

    • Reduced keyword cannibalization

    • Job detail pages started ranking better as well

      Summary Table :

    SEO ElementAction for Location + Category Pages
    URL Structure/jobs/role/city/ hierarchy
    Page ContentAdd local employers, salaries, trends
    Thin Page HandlingNoindex or redirect if jobs < threshold
    Canonical TagsPoint to primary URL if overlap exists
    Meta TagsUnique title + description with location
    Internal LinkingLink downward by relevance, vary anchor text
    Schema MarkupUse JobPosting, Breadcrumb, Organization where appropriate

     

  5. How do you scale title tags and meta descriptions for dynamic job pages without duplicating content?

    Scaling title tags and meta descriptions for dynamic job pages — especially in a large job portal — is one of the most important SEO tasks to maintain uniqueness, click-through rate, and crawl efficiency.

    Why It Matters

    In job portals, thousands of job listings may have similar content — like:

    • “Digital Marketing Executive – Bangalore”

    • “Digital Marketing Executive – Mumbai”

    Without thoughtful templating, all these pages might end up with duplicate title/meta tags, hurting SEO and click-through rates.


    🔧 Step-by-Step: How to Scale Title Tags & Meta Descriptions Without Duplication

    🔹 1. Use Dynamic Variables in Templates

    Structure your title and meta tags using dynamic tokens (from your database or CMS):

    ✅ Title Template:
    {Job Title} Jobs in {City} at {Company Name} | Apply Now

    Example Output:
    Digital Marketing Executive Jobs in Bangalore at ABC Corp | Apply Now

    ✅ Meta Description Template:
    Apply for {Job Title} at {Company Name} in {City}. {One-liner from job description}. Check salary, skills required & apply today!

    Example:
    Apply for Digital Marketing Executive at ABC Corp in Bangalore. Requires 2+ years of SEO/SEM experience. Check salary & apply today!

    2. Pull a Unique Snippet from the Job Description

    To avoid duplication in meta descriptions, extract the first 150–160 characters from the actual job description — but clean it up (no special characters, no HTML).

    Example Extraction Logic:

    meta = job_description.split(‘.’)[0][:160]

    3. Fallback Logic for Missing Data

    Not every listing has full details. Use conditionals to handle gaps:

    • If {Company Name} is missing → use “a top company”

    • If {City} is missing → fallback to “India” or general location

    This ensures no broken or awkward title/meta tags.


    🔹 4. De-Duplicate Using Slug/ID Checks

    Before publishing, run a deduplication check across:

    • Slug URLs

    • Title tag

    • Meta description

    ✅ Tools like Screaming Frog (API mode), Sitebulb, or internal scripts can help you flag duplicates before indexing.


    🔹 5. Use Schema to Reinforce Relevance (Bonus)

    While not a direct replacement for title/meta, structured data like JobPosting schema adds more rich data to SERPs — boosting CTR even if the meta description is truncated by Google.


    🔁 Real-World Example

    Before Fix:
    A job portal had 50,000 job listings — and 80% had:

    • Title: “Job Opening at Company Name”

    • Meta: “Apply now for a job at our company.”

    Google detected duplicate meta tags, and visibility dropped in GSC.

    After Fix:

    • Created dynamic templates with location + job title

    • Pulled meta descriptions from job summaries

    • Removed duplicates and blocked empty meta via QA rules

    Result:

    • Impressions up by 30% in 45 days

    • CTR improved by ~18% across key job pages

    • Index coverage improved due to cleaner tags


    🧩 Summary Table
    ElementStrategyExample Output
    Title Tag{Job Title} Jobs in {City} at {Company}“React Developer Jobs in Mumbai at TCS
    Meta DescriptionPull from description + template“Apply for React Developer at TCS. Experience with JS, React & APIs required.”

    📈 Analytics, KPIs, and Strategy

  1. Which SEO KPIs would you prioritize for a job portal? How do you differentiate between traffic quality and volume?

    Top SEO KPIs for a Job Portal
    1. Qualified Organic Traffic (by job category/location)

      • Track traffic growth for specific segments like “Digital Marketing Jobs in Bangalore”.

      • Use filters in GA4 or Looker Studio to focus on high-intent pages like job listings, company profiles, and login/signup pages.

    2. Conversion Rate (CVR)

      • % of users applying for jobs, signing up, or posting jobs.

      • Segment CVR by device, location, and source (branded vs non-branded).

    3. Indexed-to-Crawl Ratio

      • Important for large dynamic job portals.

      • Ensures Google is indexing valuable pages and not wasting crawl budget on expired/duplicate job listings.

    4. Keyword Ranking (Non-Branded + Long-Tail)

      • Prioritize rankings for terms like “fresher IT jobs in Pune” or “work from home data entry jobs”.

      • Use clustering to track keyword families by location, category, and job type.

    5. Pages with High Exit/Bounce (Intent Mismatch)

      • Analyze which job pages bring traffic but don’t lead to applications.

      • Optimize job titles/meta descriptions for clarity and intent matching.

    6. Structured Data Coverage (JobPosting Schema)

      • Essential to get visibility in Google for Jobs.

      • Track how many pages are eligible and rendered correctly with schema.

    7. Backlinks from Industry/Niche Sites

      • Especially useful for ranking competitive job category pages.

      • Quality over quantity — backlinks from HR blogs, universities, tech job boards, etc.

     

  2. How do you measure and improve the organic performance of long-tail keywords like “remote ReactJS developer job in Mumbai”?

    1. Create/Optimize a Dedicated Landing Page
    • Example: /jobs/reactjs-developer-remote-mumbai

    • Include:

      • Keyword in URL, H1, meta title, meta description

      • Schema markup (JobPosting)

      • Live job listings with filters (location + remote + skill)

    2. Content & Internal Linking
    • Add supporting content:

      • FAQs: “How to find remote React jobs in Mumbai?”

      • Blog: “Top remote ReactJS opportunities for developers in Mumbai”

    • Interlink from broader pages: /remote-developer-jobs, /reactjs-jobs-in-mumbai

    3. Improve CTR & SERP Appearance
    • Make titles and metas click-worthy:

      • Title: Remote ReactJS Developer Jobs in Mumbai – Apply Today!

      • Meta: 100% remote ReactJS jobs in top companies. Work from home or hybrid. Easy apply – No login required.

    4. Backlink Building

    • Build contextual links to that specific long-tail page from:

      • Developer communities

      • Tech blogs

      • Guest posts targeting React/remote work

    5. Job Freshness & Crawlability

    • Ensure job listings on that page are fresh and relevant.

    • Use structured data + sitemaps for fast indexing.

    • Avoid listing expired jobs — they hurt intent and user trust.


     

  3. Have you ever worked with data warehousing or BigQuery to analyze organic search at scale? What kind of insights did you derive?

  4. How do you use Google Search Console or crawl tools like Screaming Frog/JetOctopus to monitor technical SEO at scale?

    Monitoring technical SEO at scale—especially for large websites like job portals or SaaS platforms—requires a combination of Google Search Console (GSC) and crawl tools like Screaming Frog or JetOctopus. Here’s how I use them systematically:


    🔧 Using Google Search Console (GSC)
    1. Index Coverage Report
    • Identify pages that are:

      • Indexed but not submitted (orphan pages)

      • Submitted but not indexed (low-quality/thin content)

      • Crawled – currently not indexed (needs improvement or consolidation)

    At Scale: Export to Sheets/Data Studio to monitor patterns across thousands of URLs.


    2. Performance Report (Query & Page-Level SEO Health)
    • Track CTR, position, and impressions for high-value pages.

    • Identify:

      • Pages with high impressions but low CTR → Improve meta titles

      • Pages with drops in position → Check crawlability or keyword cannibalization


    3. Enhancements & Schema Monitoring
    • JobPosting schema (for job portals), FAQ, Breadcrumbs

    • Check validation status across multiple pages.

    • Fix any errors/warnings using bulk exports and regex filters.


    🕷️ Using Screaming Frog (for Deep Crawls)
    1. Crawl Setup for Large Sites
    • Set user-agent to Googlebot, restrict crawl depth or use XML sitemap mode.

    • Use custom extraction to fetch:

      • Meta tags

      • Schema presence

      • Canonical tags

      • hreflang tags (for international sites)

    2. Key Checks at Scale

    Page Speed (via API)Connect to PageSpeed InsightsIdentify pages with slow LCP/FID

    ⚙️ Using JetOctopus (for Enterprise-Scale Monitoring)

    JetOctopus is cloud-based and excels in visualization + large-scale data processing. I use it for:

    1. Log File Analysis + Crawl Budget
    • Identify how often bots crawl pages.

    • Prioritize important pages that are not getting crawled/indexed.

    2. Visual Crawl Maps
    • Detect internal linking structure, orphaned pages, and deep content issues visually.

    3. SEO Segmentation
    • Create segments like:

      • “Job Pages by Location”

      • “Pages without Schema”

      • “Pages with Thin Content”

    • Monitor health of each segment over time.

    4. Trend Monitoring
    • Track changes in errors, redirects, and indexing issues over time.

    • Set alerts for crawl anomalies (e.g., sudden rise in non-indexed URLs).

  5. Describe a time when Google deindexed a large section of your portal. How did you identify and recover from it?

    🔄 Situation: Sudden Deindexing of a Large Section (Job Portal)

    At a previous job portal I managed, we noticed a sudden 40% drop in organic impressions and traffic within just a few days. After initial checks, we discovered that thousands of job listing URLs were deindexed from Google, despite previously being stable.


    🧩 Identification: How We Caught It

    🔍 Tools Used:

    • Google Search Console:

      • Drastic drop in indexed pages in the Coverage Report.

      • Pages marked as “Crawled – Currently Not Indexed” and “Discovered – Not Indexed“.

    • Screaming Frog + Sitemap Audit:

      • Identified that our XML sitemaps included expired job URLs.

      • Many job pages were returning soft 404s (page loads, but says “Job no longer available”).

    • Log File Review (via JetOctopus):

      • Found that Googlebot was wasting crawl budget on old/expired job listings.


    🛠️ Root Cause
    • Our system wasn’t deprecating expired jobs properly.

    • Expired jobs showed a generic “not found” message but returned a 200 status code.

    • This confused Google into thinking the page was valid, but useless → got deindexed for poor content quality.

    • Over 10,000 expired jobs polluted the index and diluted the crawl budget.


    🚑 Recovery Process
    1. Technical Fixes
    • Set all expired job URLs to return a 410 (Gone) or proper 301 to similar active job/category page.

    • Implemented dynamic sitemap updates to remove expired jobs in real-time.

    • Added a rule: Jobs older than 30 days auto-expire and deindex.

    2. Content Cleanup
    • Consolidated thin job pages.

    • Added unique, structured job content with proper schema (JobPosting).

    • Added FAQs and rich content around high-volume categories to rebuild topical authority.

    3. Reindexing Strategy
    • Used the URL Inspection API to re-submit high-priority job pages.

    • Built internal links from active pages to orphaned job listings to increase crawl paths.

    • Monitored reindexing status weekly and created a Looker Studio dashboard to track “submitted vs indexed” counts.

    4. Monitoring & Communication
    • Created a new monitoring alert system in GSC (via API) to catch sudden deindexing patterns.

    • Aligned SEO, dev, and product teams on expiry logic and SEO implications.


    📈 Results (Within 6 Weeks):
    • 80% of deindexed job URLs were restored or redirected correctly.

    • Crawl stats improved by 60% (more time spent on fresh job pages).

    • Impressions and traffic fully recovered in ~6 weeks.

    • CTR improved due to fresher listings and better structured data.


    🎯 Takeaway:

    At scale, especially on job portals, expired content handling, crawl budget management, and status code accuracy are critical. A small issue like soft 404s on expired content can trigger large-scale deindexing — but a combination of GSC, crawl tools, and fast dev collaboration can recover and future-proof the platform.

     


🔗 Link Building & Authority

  1. How do you approach link building for a job portal where job listings are temporary?

    Great question — and it’s one of the trickiest parts of SEO for job portals. Since job listings are temporary, building long-term value through backlinks requires a strategic shift from URL-specific to evergreen content and category-level targeting.

    Here’s how I approach link building for a job portal with expiring listings:


    🧠 1. Focus on Evergreen, Link-Worthy Pages

    Instead of targeting individual job listings (which expire), I build links to evergreen or dynamic category pages such as:

    • /digital-marketing-jobs-in-bangalore/

    • /remote-reactjs-jobs/

    • /fresher-jobs-in-mumbai/

    These URLs stay relevant long-term and continuously refresh with active jobs, making them ideal link destinations.

    Link Strategies:

    • Guest blogging: “Top Remote Tech Jobs in India – 2025 Edition” → link to remote jobs page.

    • Resource listings: “Where to Find Digital Marketing Jobs” → submit to career or job resource directories.

    • Internal blog interlinking: Job search guides linking to category pages.


    📝 2. Publish Linkable Job Market Content

    Create high-quality, data-driven, evergreen content that earns backlinks naturally:

    Ideas:

    • “Top 10 Skills Employers Look for in ReactJS Developers (2025)”

    • “Salary Trends for Freshers in Bangalore – Industry Breakdown”

    • “Remote Work Trends in India – Based on 20,000+ Job Listings”

    Promotion:

    • Share with journalists and bloggers (HARO, Qwoted)

    • Submit to Reddit, Hacker News, LinkedIn communities

    • Partner with colleges or training institutes to get edu backlinks


    🔄 3. Redirect Strategy for Expired Listings

    If job URLs do get backlinks but later expire:

    • 301 redirect them to:

      • The relevant category page

      • A “related jobs” landing page

      • A jobs archive or job alert sign-up page

    This preserves link equity and avoids 404s.


    🤝 4. Partnerships for Mutual Backlinks

    Job portals can create win-win backlinks through:

    • Employer pages: “Featured on [Portal Name]” badges on client websites

    • Training partners: Link exchanges with digital marketing institutes or coding bootcamps

    • University placement cells: Link to your fresher job resources or guides


    🏢 5. Leverage Job Posting Schema + Google for Jobs

    While this isn’t direct link building, structured data increases visibility, which in turn increases shares and passive link acquisition — especially for high-demand jobs.


    Monitor Backlink Quality

    • Use SEMrush or Ahrefs to monitor new links.

    • Disavow spammy backlinks — job portals often attract them.

    • Build a report showing which pages accumulate the most backlinks and which redirect chains exist due to expired jobs.
