If yes, what kind of difference can I expect? 50%?
I have a large Web site and want Yahoo to index as many pages as possible as fast as possible.
Yahoo Directory Submit ($299):
https://ecom.yahoo.com/dir/submit/intro
Search Submit Basic ($49 per URL): http://searchmarketing.yahoo.com/srchsb/ssb_hiw.php)
Free submission: https://siteexplorer.search.yahoo.com/submit
The pages content changes weekly so I need fast crawling. The changes are not too big, though.
