Why Run an SEO Audit?
Every website has hidden SEO issues costing it traffic. A broken canonical tag, a missing meta description, an image without alt text — small problems that search engines notice even when you don't. Our free SEO audit tool finds them in seconds so you can fix what matters and stop losing rankings to competitors.
Google evaluates many signals across relevance, quality, usability and technical accessibility. Core Web Vitals form part of the broader page-experience picture, while helpful, reliable, people-first content remains central. This audit brings the most actionable technical and on-page checks into one place so you can identify issues and prioritize fixes.
Find Technical Errors
Catch crawl issues, broken links, slow pages, missing sitemaps, and HTTPS problems that stop Google from indexing your site.
Improve Your Rankings
Find issues that can weaken search visibility and user experience — from missing titles and duplicate signals to mobile usability and slow Core Web Vitals.
Detect AI Content
Our built-in AI content detector scans your page text for AI writing patterns — sentence uniformity, burstiness, vocabulary diversity, and transition word overuse. Know your AI score before Google does.
How often? Run a full website SEO audit monthly, or immediately after any major site change — redesign, migration, CMS update, or new content strategy.
