All about SEO Audit
SEO audits follow structured methodologies starting with Google Search Console verification checking indexing status, mobile usability, and Core Web Vitals compliance. Technical crawls via Screaming Frog uncover 404 errors, redirect chains, and orphan pages wasting crawl budget while SEMrush Site Audit prioritizes issues by impact score. On-page analysis examines title tags under 60 characters, meta descriptions compelling CTR, H1-H3 hierarchy, and internal linking distributing PageRank efficiently across content silos.
Technical Audit Checklist
XML sitemaps submit priority URLs with lastmod timestamps ensuring Googlebot discovery while robots.txt blocks thin pages without noindex tags. HTTPS enforcement via HSTS headers prevents mixed content warnings alongside canonical tags resolving duplicate issues from faceted navigation or HTTP/HTTPS versions. Log file analysis reveals inefficient crawling patterns fixable through server optimizations and JavaScript rendering improvements.
On-Page and Content Analysis
Content audits identify thin pages under 300 words, keyword cannibalization where multiple URLs compete for same terms, and missing alt text hindering image SEO. Internal linking audits ensure silo architecture with relevant anchor text while schema markup testing generates rich snippets boosting CTR 30 percent. Page speed analysis targets LCP under 2.5 seconds through image compression and critical CSS inlining.
Off-Page and Competitor Analysis
Backlink audits via Ahrefs reveal toxic profiles with spammy anchors requiring disavowals while competitor gap analysis identifies link opportunities from resource pages and guest posts. Local SEO audits verify Google Business Profile completeness, NAP consistency across directories, and review velocity impacting map pack rankings. Domain authority comparisons guide content strategy targeting winnable keywords.
