SEO check of any page: score, issues, schema, tech stack, robots.txt, sitemap, highlights, screenshots, colour picker, 340+ tools.

SEOpeck checks the SEO of any web page in one click, right in your browser. Free, no account. Score and issues: a quick 0–100 on-page score with every problem explained: title and meta description length (in pixels, like Google), missing or duplicate H1, skipped heading levels, noindex, canonical, robots.txt blocking, images without alt text, mixed content, Open Graph and broken structured data. PageSpeed: Google PageSpeed Insights for the page, mobile and desktop: Performance, Accessibility, Best Practices and SEO scores, Core Web Vitals and what to fix first. Technology: see the CMS, framework, JavaScript libraries, analytics, ads, CDN, hosting and web server a site uses. Schema: every JSON-LD item checked against Google's required and recommended properties. Highlight on page: outline images without alt text, nofollow links and H1–H6 headings directly on the page. Site files: robots.txt (with AI crawler access), XML sitemap, llms.txt and security.txt. Built-in tools: a screenshot editor (arrows, boxes, text, pixelate), a colour picker, and a screen recorder with microphone. Send a screenshot or recording straight to SEOpeck's free image and video tools. Side panel: keep the report open while you browse. 340+ tools: search every free SEOpeck tool, star favourites and open SEO tools with the page already filled in. Private by design: the extension reads a page only when you open it and keeps your results in your browser. The PageSpeed tab sends only the page address to seopeck.com to run Google's test. No account, no tracking.
