Data sources
Backlink checker for known donors
Verify backlinks on donor pages you supply: is the link there, followed, and pointing where it should. It checks your list, not a web-scale index.
Backlink checker for known donors
Your list
backlinks-check reads the donor pages you give it.
How it works
Three steps, one saved scan
Give it your donor list
Pass a target domain or URL and the donor pages you want to verify, from a list or a file. One run takes up to 500 donor URLs.
Each donor page is read
SpiderHead requests every donor, follows redirects and reads its links to the target with their anchor text, rel values and robots directives.
Get a result per donor
Each donor is marked found or missing, with a reason when a link does not pass weight, and the run ends with summary counts.
How to run it
One command
bash
seohead backlinks-check --target example.com --donors-file ./donors.txtInstall first: installation guide. Every command also runs as an MCP tool for AI agents.
