Backlinks are links from other websites to yours. They are one of the strongest signals search engines use to decide which sites rank — and which stay invisible.
This tool reads them from WARP, the web-graph engine we built ourselves over quarterly public web crawls: 133 million domains and 2.15 billion links. The same class of data commercial SEO tools charge hundreds a month for.
