Free SEO Bookmarklet Pack
15 lightweight browser tools for quick SEO checks. No extension, no account, and no setup beyond dragging a tool to your bookmarks bar.
How to use SEO bookmarklets
A bookmarklet is a normal browser bookmark that runs a small JavaScript check on the page you are viewing.
Desktop browsers recommended. You can also right-click a tool button and copy its link address to create the bookmark manually.
SEO Quick Check
See title, meta description, H1 count, canonical URL, robots directive, and URL in one compact panel.
Heading Outline
Open a clean document-order outline of all H1-H6 headings.
Image ALT Audit
Highlight images with missing, empty, or present alt attributes and show a summary.
Link Rel Highlighter
Highlight nofollow, sponsored, and UGC links directly on the page.
External Link Highlighter
Outline links that point to a different hostname.
Internal Link Highlighter
Outline links that stay on the current hostname.
Canonical & Robots Inspector
Check canonical URL and robots meta directives with one click.
Open Graph & Twitter/X
