Crawlink: SEO Page & Link Checker

See the page the way a crawler does: links, headings, meta tags, hreflang, schema, redirects and user agents.

Crawlink shows the SEO details of any page without leaving it. Click the icon and the popup opens with twelve sections. Overview opens first. It checks whether the page can be indexed, using its status code, robots.txt, meta robots, X-Robots-Tag and canonical, and shows the HTML file size against the 2 MB that Google reads. It also shows the title, description, URL, canonical and favicon, with character counts. Links lists every link on the page with its anchor text and URL, and marks it as followed or nofollow, internal or external, hidden or a duplicate. Click a row and the page scrolls to the link and outlines it. Outline-all color-codes every link at once, and you can skip sites you don't want it on. Right-click any link and choose Show link in Crawlink to open the popup with only that link listed. A hidden link or heading can be shown on the page when you click its row. Hover its hidden badge to see why it is hidden. Check status requests every web link on the page and shows each link's status code and any redirects, so broken links stand out. Headings lists every H1 to H6 as a tree and flags a missing H1, multiple H1s, skipped levels and empty headings. Click one to find it on the page, or turn on Label all headings to outline every heading on the page and put its H1 to H6 tag in front of it. Hreflang checks for a self-reference, an x-default, duplicate codes and invalid codes. Social tags shows the Open Graph and X tags and flags the ones that are missing. Schema shows each JSON-LD item as formatted JSON you can copy, and turns FAQ markup into questions you can open. Sitemaps links to the site's robots.txt and every sitemap it finds, with each sitemap's status and URL count. Rendered source opens a full view with the raw HTML, the page after scripts have run, and the difference, so you can see what JavaScript changes. Page status shows the response code and the full redirect chain, the same way the Network tab does, and puts the code on the toolbar icon. User agent loads the current tab the way a search engine or AI crawler would, or as any string you enter. JavaScript turns scripts off for the tab and compares the page with and without them, so you can see which content depends on JavaScript. Settings holds the theme, your link and heading colors, and your skipped sites. Crawlink reads the page you are on and keeps everything on your device. It sends nothing to Crawlink. The only requests it makes are the ones you ask for, such as Check status, which contacts the links on the page. It asks for access to the sites you visit so it can read the page, record redirects and apply your user agent and JavaScript settings.
