Web page title or description incorrect
Below you’ll find the steps to take when one of your webpage's title or description doesn’t show correctly in Yahoo Search.
The title and description you see for each of your webpages in Yahoo Search is generated based on your website content at the time of indexing. The document title (found between the title tags in your webpage's HTML) is used as the listing title and in most cases the description is retrieved from your webpage's description metatag, if available.
If you'd like to change one of your webpage's title or description, you can do so by updating the corresponding items on that webpage. Yahoo is not able to manually change the title or description of a listing.
