There is a Patent granted to yahoo that states that the traffic logs of an website matters in search results: Using network traffic logs for search enhancement Invented by Arkady Borkovsky, Douglas M. Cook, Jean-Marc Langlois, Tomi Poutanen, and Hongyuan Zha Assigned to Yahoo US Patent 7,398,271 Granted July 8, 2008 Filed April 16, 2002 Better Web Crawling: Usually a search engine crawling program discovers new pages to index by finding links to pages on the pages that they crawl. The crawling program may not easily find sites that don’t have many links pointing to them. But, pages that show up in log files from ISPs or toolbars could be added to the queue of pages to be crawled by a search engine spider Pages that don’t have many links to them, but show up frequently in log information may even be promoted for faster processing by a search crawler. So the number of visitors to your site does matter, use http://traffic.wtools.eu for cheap traffic. Hope this helps many members.
I read through some of the patent info and it looks like it could really change their results and provide something maybe even better than what Google can with their link based algorithm. It is something different and Yahoo needs to do something to regain their edge in the market.
I hope yahoo will create a search engine which is brain based. Yahoo will provide users with a pc-to-brain connector then uses brain signals to determine the website they have visited.
Thanks for your url . I have read the patent . It is a bit complex . I believe it will help for ranking in yahoo . But I want to know if it is possible for spider to crawl log files in theory ? Any one can offer help ?
