Free Technical SEO Audit Tool — Check Any Website InstantlyThe ZagosaSocial Free SEO Audit Tool performs a comprehensive technical SEO analysis of any website in seconds. Enter your domain and receive an instant, detailed report covering all the key technical SEO factors that affect your search engine rankings. The audit checks security and HTTPS configuration including HTTP to HTTPS redirects and consistent www versus non-www handling. It analyses your robots.txt and sitemap.xml files to ensure search engines can discover and crawl your pages. It checks every page for proper H1 heading structure, unique title tags, and meta descriptions of the correct length. For each page crawled, the tool evaluates server-side rendering and content visibility — identifying whether search engines see your actual content or an empty JavaScript shell. It checks for canonical tag implementation, Open Graph and Twitter Card social sharing tags, and mobile viewport configuration. Indexing settings are verified to ensure no unwanted noindex directives are blocking your pages from Google. The tool also assesses structured data including JSON-LD schema markup — checking for valid syntax and recommending relevant schema types like Organization, WebSite, BlogPosting, and FAQPage. Image alt text compliance, internal linking, and duplicate content (both title and meta description duplication) are all analysed across every page checked. Each finding is categorised by severity — Critical, High, Moderate, or Low — with a clear explanation of the issue and actionable steps to fix it. The full report can be exported as a CSV file for sharing with your development team or SEO agency. The tool is completely free to use with no account required. It audits up to 12 pages per run and is built using the same technical SEO framework powering the ZagosaSocial platform's internal content scoring system. No registration or login is required to run an audit. Simply enter any website URL and receive your full technical SEO report within seconds. Results are available to export as a CSV file immediately after the audit completes, making it easy to share findings with your web developer or SEO agency.
