I always had this problem. Whenever I start harvesting something I have the feeling that I get to few results. For example I am searching with this footprint: site:.edu Custom footprint I get some results and if I remove duplicates all that remains are 2500 links. If I check google in firefox for site:.edu I get 141 million results. Why does SB show only 2500 then? I am using SB standard settings and 10 private proxies from yourprivateproxy. So why do I get so few results?
