Enter any public website URL and run a free SEO audit in seconds. You get a scored report with every check labeled Passed, Warning, or Error — plus specific findings (broken URLs, missing alt text, title length, and more) grouped into easy-to-scan sections.
What this audit checks (9 areas, 90+ individual checks):
Title tag length, meta description, title–H1 and title–description relevance, canonical URL and self-reference, viewport for mobile, HTML language, and legacy meta keywords.
HTTP status and redirects, HTTPS, page indexability, nofollow rules, modern HTTP protocol, HTML5 doctype, charset, meta robots, robots.txt reachability, crawl rules, favicon, compression, and cache headers.
H1 and H2 structure, heading hierarchy, word count, text-to-HTML ratio, semantic HTML (main, nav, header, footer), skip-navigation links, and on-page anchor links.
Image alt text (with specific file paths), empty alt attributes, width/height for CLS, lazy-loading usage, modern WebP/AVIF formats, and embedded video or iframe content.
Internal and external link counts, sampled broken links (with exact URLs and status codes), empty hrefs, rel="noopener", internal nofollow, pagination rel next/prev, breadcrumb navigation, mixed HTTP content, XML sitemap, and sitemap in robots.txt.
Open Graph tags (title, description, image, url, type, site name), absolute OG image URLs, title vs og:title consistency, and Twitter Card fields for link previews on social platforms.
JSON-LD and microdata detection, schema types (Organization, WebSite, WebPage, BreadcrumbList, FAQ, Article, Product, LocalBusiness, VideoObject), and JSON-LD syntax validity.

The tool scans your page for 90+ SEO signals grouped into clear sections: Technical, On-Page, Social & Meta, Content, Sitemaps, Schema, Links, Security, Performance, and Core Vitals.
Start with the overall score and Passed / Errors / Warnings counts. Use the section sidebar (Technical, On-Page, Links, etc.) to focus one area at a time. Each row names the check, shows what was found (including specific URLs or values), and includes a short fix tip. Filter tabs let you view All Checks, Passed, Errors, or Warnings.
Errors are critical problems that can hurt rankings or indexing — for example a missing title tag or blocked robots rules. Warnings are improvements worth making — such as a title that is too short or a missing optional Open Graph image. Passed checks mean that item looks good.
This tool gives a fast, unified on-page and technical snapshot from a live fetch of your URL. It complements Google tools: use Search Console for index coverage and crawl stats, and PageSpeed Insights for detailed lab and field Core Web Vitals. Performance scores here are estimates based on load time and page weight.
Sign in to run bulk audits — paste up to 10 URLs (one per line) and compare scores side by side. Single-site audits work without an account.
