Technical SEO Mastery
Complete technical SEO audit, fix, and monitoring system. From crawlability to Core Web Vitals to international SEO — everything search engines need to find, crawl, index, and rank your site.
When to Use
"Technical SEO audit for my site" "Why isn't Google indexing my pages?" "Fix Core Web Vitals issues" "Pre-migration SEO checklist" "My site is slow / rankings dropped" "Check robots.txt / sitemap / schema markup" "International SEO / hreflang setup"
Phase 1: Quick Health Check (5-Minute Triage)
Before a full audit, run a rapid assessment. Fetch the site and check: quick_health: url: "[domain]" checks: robots_txt: "[accessible / blocked / missing]" sitemap_xml: "[found / missing / errors]" https: "[yes / mixed content / no]" mobile_viewport: "[set / missing]" page_load: "[fast <2s / moderate 2-4s / slow >4s]" h1_present: "[yes / missing / multiple]" canonical: "[set / missing / self-referencing]" structured_data: "[present / missing / errors]" severity: "[healthy / needs work / critical]" priority_fix: "[top issue to address first]" Severity guide: 🟢 Healthy: 0-1 issues — minor optimizations only 🟡 Needs work: 2-4 issues — schedule fixes this week 🔴 Critical: 5+ issues or any blocking issue — fix immediately
2.1 Robots.txt Analysis
Fetch [domain]/robots.txt and evaluate: robots_txt_audit: exists: true/false valid_syntax: true/false issues: - type: "[blocked_important_page / missing_sitemap / wildcard_block / syntax_error]" detail: "[specific line or pattern]" severity: "critical/warning/info" fix: "[exact fix]" checks: - "Sitemap directive present" - "No accidental blocking of CSS/JS/images" - "No blocking of important page directories" - "Correct user-agent targeting (Googlebot, Bingbot, etc.)" - "No conflicting rules (allow + disallow same path)" - "Crawl-delay only if needed (slows indexing)" Common mistakes: MistakeImpactFixDisallow: / blocking everythingNo pages indexedRemove or narrow scopeBlocking CSS/JSPoor rendering = ranking dropAllow: /assets/No sitemap referenceSlower discoveryAdd Sitemap: directiveMultiple sitemaps not declaredPartial crawlingDeclare all sitemapsBlocking search/filter pages poorlyCrawl wasteUse Disallow: /*? patterns Recommended template: User-agent: * Allow: / Disallow: /admin/ Disallow: /api/ Disallow: /checkout/ Disallow: /*?sort= Disallow: /*?filter= Sitemap: https://example.com/sitemap.xml Sitemap: https://example.com/sitemap-images.xml
2.2 XML Sitemap Audit
Fetch sitemap(s) and evaluate: sitemap_audit: url: "[sitemap URL]" type: "[index / single / none]" url_count: 0 issues: - type: "[missing / too_large / includes_noindex / stale_lastmod / broken_urls]" severity: "critical/warning/info" fix: "[specific action]" quality_checks: - "All URLs return 200 (no 404s, 301s, or 5xx)" - "No noindex pages included" - "lastmod dates are accurate (not all same date)" - "Under 50,000 URLs per sitemap file" - "Under 50MB uncompressed per file" - "Sitemap index if >50K URLs" - "Matches canonical URLs (not alternate versions)" - "Images/video sitemaps if applicable" Sitemap best practices: One URL per <url> entry — canonical version only lastmod should reflect actual content change date Priority and changefreq are largely ignored by Google — optional Compress with gzip for large sitemaps Submit in Google Search Console AND robots.txt
2.3 Crawl Budget Optimization
crawl_budget_analysis: total_pages: 0 indexable_pages: 0 crawl_waste_ratio: "[indexable / total — target >80%]" waste_sources: - source: "[faceted navigation / pagination / parameters / duplicate content / thin pages]" page_count: 0 action: "[noindex / canonical / robots block / parameter handling / consolidate]" optimization_priority: 1: "Remove/noindex thin and duplicate pages" 2: "Consolidate parameter variations with canonicals" 3: "Implement pagination best practices (rel=next or load-more)" 4: "Fix redirect chains (max 1 hop)" 5: "Eliminate orphan pages or link them into site structure" Crawl budget matters when: Site has >10K pages OR crawl rate is notably low in Search Console.
3.1 Index Status Check
For each important page type, verify: indexability_check: page_type: "[homepage / product / blog / category / landing]" sample_url: "[URL]" signals: meta_robots: "[index,follow / noindex / nofollow / none]" x_robots_tag: "[present / absent — check HTTP headers]" canonical: "[self / points to other URL / missing]" http_status: "[200 / 301 / 302 / 404 / 410 / 5xx]" in_sitemap: true/false internal_links_to: "[count of internal links pointing here]" robots_txt_allowed: true/false verdict: "[indexable / blocked / conflicting signals]" fix: "[action if not indexable]"
3.2 Common Indexing Blockers

9.1 Hreflang Implementation
international_seo: approach: "[subdirectories /en/ / subdomains en. / ccTLDs .co.uk]" # Recommended: subdirectories (easiest to manage, inherits domain authority) hreflang_audit: implemented: true/false method: "[HTML link tags / HTTP headers / sitemap]" issues: - "Missing return links (A→B exists but B→A missing)" - "Wrong language/region codes" - "Missing x-default tag" - "Self-referencing hreflang missing" Hreflang template: <link rel="alternate" hreflang="en-us" href="https://example.com/en-us/page" /> <link rel="alternate" hreflang="en-gb" href="https://example.com/en-gb/page" /> <link rel="alternate" hreflang="es" href="https://example.com/es/page" /> <link rel="alternate" hreflang="x-default" href="https://example.com/page" /> Rules: Every page must reference ALL language versions including itself Always include x-default (fallback for unmatched languages) Use ISO 639-1 for language, ISO 3166-1 Alpha 2 for region Hreflang must be bidirectional (if A references B, B must reference A) Canonical and hreflang should align — canonical should point to same-language version
9.2 International Targeting Checklist
Correct hreflang on all pages (bidirectional) x-default specified Content genuinely translated (not just auto-translated) Local currency, date format, phone numbers Geo-targeting set in Search Console (for ccTLDs/subdirectories) Local server / CDN node in target country Local backlinks from target region Language-specific sitemap or sitemap section
Phase 10: Site Migration SEO Checklist
Use when changing domains, restructuring URLs, or redesigning: migration_checklist: pre_migration: - "Crawl current site — full URL inventory" - "Export all current rankings and traffic data" - "Map every old URL to new URL (1:1 redirect map)" - "Backup robots.txt, sitemaps, .htaccess" - "Document all existing 301 redirects" - "Note top 100 pages by traffic — verify redirects" - "Test staging site (is it blocked from indexing?)" - "Verify new site has all schema markup" - "Check canonical tags on new site" - "Prepare new sitemap" migration_day: - "Implement all 301 redirects" - "Update robots.txt (unblock new site)" - "Submit new sitemap to Search Console" - "Update Google Search Console property if domain changed" - "Verify HTTPS redirect chain is clean" - "Test 50 random old URLs — confirm redirects work" - "Check for redirect chains or loops" - "Monitor server errors / 5xx in real-time" post_migration: week_1: - "Monitor Search Console for crawl errors daily" - "Check index coverage report" - "Verify organic traffic hasn't cratered" - "Fix any 404s appearing in crawl reports" month_1: - "Compare rankings: pre vs post migration" - "Check all structured data still validates" - "Verify internal links updated (no redirect-through links)" - "Monitor Core Web Vitals on new infrastructure" month_3: - "Full ranking comparison" - "Traffic recovery assessment (expect 80-100% recovery)" - "Clean up any remaining redirect chains" expected_traffic_impact: best_case: "2-4 weeks dip, full recovery" typical: "1-3 months for full recovery" worst_case: "6+ months if redirects missed — audit immediately"

13.1 JavaScript SEO
javascript_seo: rendering: "[CSR / SSR / SSG / ISR / hybrid]" checklist: - "Critical content visible in initial HTML (view-source test)" - "Googlebot can render JS — check with URL Inspection tool" - "No content behind user interaction (click to load)" - "Internal links are `<a href>` tags (not JS click handlers)" - "Lazy-loaded content uses Intersection Observer (not scroll events)" - "Dynamic rendering for critical pages if needed" - "Meta tags in initial HTML (not injected by JS)" - "Canonical tags in initial HTML" framework_specific: nextjs: "Use SSG/ISR for content pages, SSR for dynamic" react_spa: "Consider prerender.io or dynamic rendering" angular: "Angular Universal for SSR" vue: "Nuxt.js for SSR/SSG"
13.2 Log File Analysis

Phase 14: Common Technical SEO Mistakes
#MistakeWhy It MattersFix1Blocking staging site from indexing, forgetting to unblock at launchZero pages indexedCheck robots.txt + meta robots at launch2Using 302 instead of 301 for permanent redirectsLink equity not passedSwitch to 3013Multiple versions of homepage indexed (www/non-www, HTTP/HTTPS, trailing slash)Diluted authorityPick one canonical, redirect all others4Orphan pages with no internal linksNever found by crawlersAdd to navigation or contextual links5Sitemap includes noindex pagesConflicting signalsFilter sitemap to indexable pages only6Missing alt text on imagesAccessibility + image SEO lossAdd descriptive alt text to all images7Not monitoring Core Web Vitals after deployPerformance regressionsSet up CrUX monitoring + alerts8Redirect chains (A→B→C→D)Slow + link equity lossFlatten to single hop9Large unoptimized imagesSlow LCP, page weightWebP/AVIF + responsive srcset10No HTTPS or mixed contentTrust signal lost, browser warningsFull HTTPS migration
E-commerce (1000s of product pages)
Faceted navigation: canonical to base category, noindex filter combos Out-of-stock pages: keep page, show "out of stock" (don't 404) Pagination: use rel=canonical to collection page or implement load-more
Single Page Applications (SPAs)
Pre-rendering or SSR is mandatory for SEO Check that <a href> tags exist in HTML (not just JS routing) Test with JavaScript disabled — is critical content visible?
Large sites (100K+ pages)
Sitemap index with multiple child sitemaps Crawl budget optimization is critical Consider dynamic XML sitemaps that auto-update Log file analysis to understand actual crawl behavior
WordPress specific
Install Yoast/RankMath for technical SEO basics Check theme isn't injecting bad schema Minimize plugins (each adds JS/CSS weight) Use object caching (Redis) + page caching (WP Super Cache/W3 Total Cache)
After a Google algorithm update
Don't panic — wait 2 weeks for volatility to settle Compare affected pages vs unaffected — find the pattern Check Search Console for manual actions Focus on content quality and E-E-A-T, not just technical fixes
