Description
On-page SEO audit tool. Check meta tags, schema markup, hreflang, redirects, and broken links from a Chrome side panel. CrawlRaven is a free on-page SEO audit toolbar that runs in the Chrome side panel, so you can analyze any web page's technical SEO without leaving the tab you're on. Open the side panel on any URL and instantly check the SEO signals that matter: • Overview — title tag, meta description, canonical, robots/meta-robots, indexability status, and XML sitemap detection. • Headings — full H1–H6 outline so you can spot missing H1s, skipped levels, and weak heading structure. • Links — internal, external, nofollow, and broken link checks with live HTTP status codes. • Images — missing alt text, oversized files, non-HTTPS sources, and broken images. • Schema — JSON-LD structured data validation plus hreflang checks for international SEO. • Social — Open Graph and Twitter Card preview to see how your page looks when shared. • Advanced — HTTP response headers, redirect chains, and a raw-vs-rendered HTML comparison. Built for SEO specialists, content marketers, web developers, and site owners who need a fast, accurate on-page SEO checker and schema markup validator. No sign-up, no account — just open the panel and audit.
