A free SEO audit is the fastest way to find out what's holding your website back from ranking higher on Google. But not all audits are created equal. Some check a handful of basic signals, while others dig deep across dozens of categories.
This guide explains what a thorough free SEO audit should cover, why each check matters, and how to act on the results.
Why Run an SEO Audit?
Most websites have issues their owners don't know about. Missing meta descriptions, broken links, slow load times, blocked crawlers — these problems silently drain your organic traffic without any visible warning signs.
An SEO audit surfaces these hidden issues and tells you which ones matter most. Think of it as a diagnostic scan: you might feel fine, but a checkup reveals the problems you can't see.
What a Free SEO Audit Should Check
On-Page SEO Fundamentals
These are the building blocks of search engine optimization:
- Title tags — Is every page's title unique, descriptive, and within 50-60 characters?
- Meta descriptions — Does each page have a compelling meta description that encourages clicks?
- Header structure — Does each page have exactly one H1, with H2s and H3s used logically?
- Image alt text — Do all images have descriptive alt attributes for accessibility and SEO?
- Internal links — Are important pages well-connected through contextual links?
Technical SEO
Technical issues can prevent search engines from even finding your content:
- HTTPS — Is your site served over a secure connection?
- Robots.txt — Are you accidentally blocking search engines or AI crawlers? Check with our robots.txt analyzer.
- XML sitemap — Does your site have a sitemap submitted to Google Search Console?
- Canonical tags — Are duplicate pages properly handled?
- Mobile responsiveness — Does your site work well on phones and tablets?
Page Speed
Google uses Core Web Vitals as a ranking factor. A good audit checks:
- Largest Contentful Paint (LCP) — How long until the main content loads?
- First Input Delay (FID) — How quickly does the page respond to user interaction?
- Cumulative Layout Shift (CLS) — Does the page layout jump around as it loads?
Content Quality
Thin, low-quality content is one of the most common reasons websites fail to rank:
- Word count — Pages under 300 words rarely rank for competitive terms
- Content depth — Does the content thoroughly cover the topic?
- Readability — Is the content accessible to your target audience?
AI Visibility
This is something most free audit tools miss entirely. ChatGPT, Gemini, Perplexity, and Claude are sending real traffic to websites. A thorough audit checks whether your site is visible to AI-powered search.
Security, Accessibility, and More
A truly comprehensive audit also checks security headers, accessibility issues, social media tags (use our Open Graph previewer to check yours), local SEO signals, and conversion elements.
What to Do With Your Audit Results
The key is prioritization. Don't try to fix everything at once. Instead:
- Focus on high-impact issues first — ScoreCraft ranks findings by impact so you know what matters most
- Fix the quick wins — Missing meta descriptions, broken links, and missing alt text can be fixed in hours
- Plan for bigger projects — Page speed optimization and content expansion take more time but have lasting impact
- Re-audit regularly — Track your SEO score over time to measure progress
