Does Yahoo! Have a Sandbox?
I’ve been hearing increased conjecture about a Yahoo Sandbox, similar to the well known and largely mythical Google Sandbox. People who find it takes many months for their new web site to show up in rankings in Yahoo or Google often assume that these search engines have some sort of “new site filter” that’s keeping them from showing up.
I don’t think that’s it at all. It takes a certain amount of inbound link popularity for these search engines to think your site is worthy of appearing near the top of the list. Not only does it take time to get quality inbound links, but it takes additional time for those links to be all accounted for by the search engines before they accrue any benefit to your site.
Withy that said, and not to denigrate the importance of link popularity in Google, Yahoo is much more weighted in favor of on-page content. If you have plenty of keyword-rich content on lots of value-packed pages (value to the human visitors to your site) then you’ll do better in Yahoo.
