The Value of Fresh Target Data
A list with 500,000 URLs sounds much better than one with 50,000. In practice, a bloated list loaded with dead domains, oversubmitted platforms, and prohibited IPs slows GSA SER down, burns through your proxy threads quicker, and produces less confirmed links per hour than a smaller, tighter list would. The three things that in fact figure out a confirmed link list's quality in 2026 are: how just recently each URL was validated as live and accepting submissions outgoing link count per domain.
A 100,000 URL list where every entry was confirmed today, has OBL under 70, and covers the right engines will surpass a 2,000,000 URL fixed dump every time. A page that connects to 200 other websites passes roughly 1/200th of its readily available PageRank to each of them. A page connecting to 12 sites passes 1/12th.
