How to do an SEO audit: the definitive guide
An SEO audit is the diagnostic that reveals exactly why your site isn't ranking where it should. Whether your organic traffic has plateaued or you're launching a new SEO initiative, a systematic audit provides the roadmap for measurable improvement. Here's how to conduct one that actually drives results.
Set your baseline metrics
Before diving into the audit, establish your current performance benchmarks. Document organic traffic, keyword rankings, indexed pages, Core Web Vitals scores, and Domain Rating in Ahrefs. Without a baseline, you cannot measure the impact of your optimizations. Pull 6-12 months of Google Search Console and Analytics data to understand seasonal patterns and long-term trends.
Crawl your entire site
Run a full crawl using Screaming Frog or Ahrefs Site Audit. This reveals the complete picture — every URL, status code, redirect, meta tag, heading, and internal link on your site. Export the data and organize it by issue severity. Focus first on server errors (5xx), broken pages (4xx), and redirect chains that waste crawl budget.
Analyze keyword performance
Pull your Google Search Console keyword data and cross-reference with Ahrefs organic keywords. Identify pages ranking on page 2 (positions 11-20) — these are your best quick wins. Find keyword cannibalization where multiple pages compete for the same term. Map every target keyword to a single page and ensure content strategy supports each cluster.
Evaluate content quality
Review your top 50 pages by traffic. Are they comprehensive? Do they answer the search intent fully? Compare word count, structure, and depth against the top 3 ranking competitors. Identify thin content that should be expanded or consolidated. Check for outdated statistics, broken examples, and missing internal links. Content that doesn't serve users or search engines should be improved or removed.
Build your action plan
Organize all findings into a prioritized action plan sorted by impact vs effort. High-impact, low-effort items go first — fixing broken links, adding missing meta descriptions, improving page speed. Medium-effort items like content optimization and schema implementation come next. Long-term items like site architecture changes and link building campaigns round out the plan.
