To see if your site is indexed but is not showing up in search results for a particular query, search for your site using the title and an identifiable unique phrase from the text on your page.

If you want a page to appear in web search results, make sure that page includes some unique text to be indexed. Pages with no unique text or no text at all might drop out of the index or might never be indexed. Also, refer to the Site Guidelines to see whether your site is in compliance with Yahoo!7's content policies. Sites that violate the Yahoo! Site Guidelines might be removed from the index.

Finally, it is possible that your site was unavailable for crawling during an index refresh, and it could reappear following another index update.
