Crawlhive - SEO Audit, Site Crawler & Technical SEO

Crawlhive is a free SEO checker for on-page and technical SEO that does not stop at the page you are on. It runs a full on-page SEO analysis of the open tab, then crawls the rest of the site and reports what only a whole site audit can show — duplicate titles, orphan pages, pages buried too deep for search engines to crawl properly. Everything runs in your browser. The pages you audit are never uploaded anywhere. One click gives you an SEO audit of the page, a technical SEO check of how search engines see it, a site crawl, Core Web Vitals, and a report you can hand to a client. ━━━ TECHNICAL SEO: WHY PAGES GO MISSING FROM GOOGLE ━━━ Three separate things can quietly keep a page out of the index, and only one of them is visible in the HTML: ✔ meta robots — the one every SEO extension reads ✔ X-Robots-Tag — an HTTP response header, invisible on the page itself ✔ robots.txt — parsed properly, with wildcards and longest-match rules Crawlhive checks all three and tells you which file to open. A noindex that moved from staging to production is the most expensive bug in SEO precisely because nothing on the page shows it. ━━━ SITE AUDIT: A CRAWL, NOT JUST ONE PAGE ━━━ One click follows the internal links from the page you are on and reads each page's HTML: ✔ Duplicate title tags — two pages competing with each other in search results ✔ Site-wide noindex — every blocked page, meta tag or header ✔ Broken internal links, with real status codes ✔ Missing titles, descriptions and H1s ✔ Click depth — pages sitting four or more clicks from the start, where crawlers rarely reach ✔ Weakly linked pages — the ones almost nothing points to ✔ Orphan pages — in your sitemap, but no link anywhere leads to them ✔ Pages reachable by clicking that are missing from the sitemap ✔ Canonical tags pointing somewhere else ✔ Internal links landing on a redirect Same origin only. Paths disallowed in robots.txt are skipped without a request, and anything that looks destructive — logout, delete, checkout — is never touched. ━━━ SEO SCORE AND WHAT TO FIX FIRST ━━━ A single number out of 100, and the issues ranked by how many points each one is costing you. The number beside every line is exactly what fixing it returns, so the order is not a matter of opinion. Re-check the page and the score shows whether it moved. ━━━ SEARCH RESULT PREVIEW, MEASURED IN PIXELS ━━━ Google truncates a result by pixel width, not character count — a title in capitals runs out far sooner than the usual "30-60 characters" rule suggests. Crawlhive measures the real width in Google's own font and cuts the preview exactly where the search results would. Open Graph and Twitter Card previews render as real cards. ━━━ PAGE SPEED AND CORE WEB VITALS ━━━ ✔ Core Web Vitals — LCP, CLS, plus TTFB and FCP ✔ Render-blocking files — every stylesheet and script holding up the first paint ✔ Page weight broken down by type: images, scripts, CSS, fonts, XHR ✔ Heaviest images, and images larger than the box they are drawn in ✔ DOM size and the full load timeline ━━━ FULL ON-PAGE SEO ANALYSIS ━━━ ✔ Title and meta description with length checks ✔ Canonical URL, from the tag or the Link header ✔ H1-H6 outline with hierarchy warnings and duplicate detection ✔ Images without alt text, dimensions, lazy loading ✔ Internal, external, nofollow and empty-anchor links ✔ Internal link checker with real HTTP status codes ✔ Structured data validated against the properties Google actually requires — not just "Product found", but "Product found, but no offers, so no rich result" ✔ hreflang: self-reference, duplicate codes, invalid codes, relative URLs ✔ Sitemap detection, and whether this URL is listed in it ✔ Response headers: status, content-type, encoding, X-Robots-Tag ✔ The HTML before JavaScript runs, compared against the live DOM — a title or H1 that only appears after scripts is not there when a crawler first reads the page ━━━ EXPORT ━━━ ✔ Copy the whole report as Markdown, ready to paste into an email to a client ✔ Download the raw data as JSON ✔ CSV for links, images and crawl results, ready for a spreadsheet ━━━ PRIVACY ━━━ The pages you audit are read where they are and never uploaded. The requests Crawlhive makes go to the site you already have open — its robots.txt, its sitemap, its own pages. Nothing about your browsing reaches us or anyone else. Signing in with Google is required. Only your name, email address and profile picture are used, so one account works across our extensions. ━━━ 49 LANGUAGES ━━━ English, Turkish, German, Spanish, French, Italian, Portuguese, Russian, Japanese, Korean, Chinese, Dutch, Polish, Swedish, Danish, Norwegian, Finnish, Czech, Slovak, Hungarian, Romanian, Ukrainian, Greek, Bulgarian, Croatian, Serbian, Slovenian, Lithuanian, Latvian, Estonian, Catalan, Arabic, Hebrew, Persian, Hindi, Bengali, Tamil, Telugu, Malayalam, Marathi, Gujarati, Kannada, Indonesian, Malay, Vietnamese, Thai, Filipino, Swahili, Amharic. ━━━ WHO IT IS FOR ━━━ SEO specialists running a technical SEO audit, developers checking a deploy did not ship a noindex, agencies producing a website audit for a client, and anyone who wants to know why a page is not ranking. No rank tracking, no backlink data, no AI guesswork — just what your page and your site actually contain.
