SEO Audit
An SEO audit is a comprehensive analysis of a website's technical health, on-page optimization, off-page authority, and content quality to identify issues and opportunities for improvement.
§ 1 Definition
An SEO audit is the diagnostic phase. It answers: what is broken, what is missing, what is underperforming, and what is working. A thorough audit covers technical SEO (crawlability, indexation, site speed, mobile responsiveness, structured data), on-page SEO (title tags, meta descriptions, heading structure, content quality, keyword alignment), off-page SEO (backlink profile, toxic links, brand mentions), and competitive analysis (what are competitors doing better?).
§ 2 Audit Frequency
Full audits should happen quarterly (or after any major site change). Quick monthly health checks (crawl errors, index coverage, Core Web Vitals) are good practice between full audits. High-traffic sites should consider continuous monitoring tools.
§ 3 Common Audit Findings
The most common issues discovered in audits: missing or duplicate title tags, missing or thin meta descriptions, broken internal links, slow Core Web Vitals, pages blocked by robots.txt that should not be, orphan pages with no internal links, soft 404s, and inconsistent NAP data (for local businesses).
§ 4 Note
- An SEO audit diagnoses technical, on-page, off-page, and content issues
- Full audits quarterly; quick checks monthly
- The output must be a prioritized action plan

## Note
An audit that produces a 50-page PDF but no prioritized action plan is a waste of money. The output of a good audit is a prioritized list: P0 (critical, fix now), P1 (important, fix this week), P2 (worthwhile, fix this month), and P3 (nice to have).
