Social bookmarking sites list (with DA and referring domains)
This list comes from the SEO Agent library: 181 social bookmarking and link-submission sites, each one verified as reachable this month, with Domain Authority, referring domains from DataForSEO, and whether the link it gives is dofollow. The free list bundled with the agent includes the rows marked below; the full library, with the step-by-step method for every site, needs a free API key.

How the agent builds this kind of link
Bookmark or link submission. Find “Add link”, “Submit”, “Add URL” or “Post”. Fill URL, title (use the anchor text or a descriptive title containing it), description (one or two sentences), category and tags. Submit. Verify on the new bookmark’s page or the listing that shows it. Pitfalls: many of these are Pligg or Scuttle clones with a captcha at submit; if it appears, report manual. Some show the link only after a moderator approves, report unverified with the submission page URL.
Build one with your AI assistant
Install SEO Agent in Claude, Cursor or Codex, then ask:
Use get_method for one of the social bookmarking sites above and build a link to my site.
The agent follows the site’s steps in its own browser, places the link, opens the public page to verify it, and logs the result.
