How often should I do an SEO audit?

A full SEO audit should be conducted quarterly for active websites. For large sites with frequent content changes, a monthly technical crawl check is recommended in addition to the quarterly deep audit.

What is the most important thing to fix in an SEO audit?

Core Web Vitals (especially LCP under 2.5 seconds) and crawl errors are the highest-priority technical fixes. After that, focus on pages with high impressions but low click-through rates — improving titles and meta descriptions can deliver fast wins.

Do I need paid SEO tools to do an audit?

No — Google Search Console, Screaming Frog (free up to 500 URLs), and Google PageSpeed Insights are all free and cover the most critical audit areas. Paid tools like Ahrefs or SEMrush are helpful for backlink analysis but not mandatory.

Crawl your website using Screaming Frog (free up to 500 URLs) or Sitebulb 💡 A crawl reveals broken links, duplicate content, missing meta, and redirect chains.
Check Google Search Console for crawl errors, index coverage, and manual penalties 💡 Click 'Index > Pages' to see which URLs are excluded and why.
Analyze your Core Web Vitals: LCP, INP, and CLS scores in Google PageSpeed Insights 💡 Target: LCP < 2.5s, CLS < 0.1, INP < 200ms. These are Google ranking signals.
Check your site's mobile-friendliness using Google's Mobile-Friendly Test tool 💡 50%+ of web traffic is mobile — poor mobile UX directly harms rankings.
Review your sitemap.xml: ensure it's submitted to Google, up to date, and free of 4xx/5xx URLs 💡 Remove noindexed and redirected URLs from your sitemap to avoid confusing Googlebot.
Audit your robots.txt: ensure you're not accidentally blocking important pages from Google 💡 Test your robots.txt in Google Search Console's robots.txt tester tool.
Review title tags and meta descriptions for every key page (unique, keyword-rich, correct length) 💡 Title: 50–60 characters. Meta description: 120–155 characters. No duplicates.
Analyze heading structure: one H1 per page, logical H2/H3 hierarchy, keywords in headings 💡 Use Screaming Frog to identify pages with missing H1s or multiple H1s in bulk.
Check your internal linking structure: every important page should be reachable within 3 clicks 💡 Deep orphaned pages receive minimal PageRank — link to them from your sitemap or navigation.
Audit your backlink profile using Ahrefs (trial), SEMrush, or Moz: identify toxic links 💡 Disavow toxic backlinks via Google Search Console only if they're genuinely manipulative.
Identify your top 10 organic landing pages and ensure they have strong E-E-A-T signals 💡 E-E-A-T: Experience, Expertise, Authoritativeness, Trustworthiness — Google's quality criteria.
Create a prioritized fix list: High impact/low effort fixes first 💡 Use the calculator to estimate traffic lift per fix based on current position and CTR data.
