Why run a free SEO audit?
A free SEO audit is the essential first step to understand why your website isn’t generating the expected traffic. Every day, thousands of potential visitors miss your business because Google can’t find your site, doesn’t understand it correctly, or judges it technically deficient.
Our SEO audit tool instantly analyses your homepage against 25+ criteria aligned with 2026 best practices: title tags and meta description, H1/H2/H3 title structure, alt attributes on images, HTML weight, server response time, Schema.org structured data, HTTPS security, mobile compatibility. No signup, no email required: everything runs in your browser in under 30 seconds.
Unlike classic online SEO audits that ask for your credit card after showing 3 lines of results, our free SEO analysis gives you the complete report immediately. You leave with a global score out of 100 and a clear priority list.
The 5 categories analysed by our SEO audit
Our SEO report groups checks into 5 categories aligned with official recommendations from Google Search Central, with an independent score for each:
- Technical SEO — Title tag (optimal 50-60 chars), meta description, canonical URL, robots directives, Open Graph Facebook, Twitter Card, schema.org JSON-LD markup, hreflang language management.
- Structure — Unique H1, presence of H2 to structure content, alt attributes on images, internal/external link ratio, language declaration on the html tag.
- Performance — Initial HTML weight (target < 200 KB), server response time (target < 800 ms), number of external scripts, stylesheets loaded, excessive inline CSS.
- Mobile & security — Viewport meta correctly defined, HTTPS enabled, HSTS, X-Content-Type-Options, Content-Security-Policy.
- Content — Text volume (target > 300 words), lexical richness (unique words), presence of media (images, videos).
At the end of the online SEO audit, you get a weighted global score out of 100. A score ≥ 80 means your site follows most best practices. Between 60 and 80, there are still significant areas for improvement. Below 60, expert guidance is strongly recommended.
How to fix the issues detected by the SEO audit?
Each issue detected by our free SEO tool comes with a specific recommendation. The most common quick fixes include: updating the title tag and meta description to include your main keyword, adding alt attributes to all images, optimising server response time (switching to a performant host, activating a CDN), and adding Schema.org for rich snippets. You can use our additional SEO audit tools (Meta Tags Generator, Schema.org, Slug, Density) to quickly generate the corresponding code.
