What Is The New Meta Tag Called "NOYDIR"?
Yahoo! recently announced implementation of support for a special HTML tag called "NOYDIR." This tag complements the already-supported "NOODP" tag accessible by all major search engines.
Google, Yahoo! and other major search engines often use the information for the title and description of a website found in the Open Directory Project or Yahoo! Directory to populate their search engine result pages. However, these titles and descriptions as the directories have them are not always what the webmasters intended. They can be outdated or flat-out misguiding for users. Essentially, if webmasters included the NOODP tag (<meta name="robots" content="NOODP">) in a page search engines would recognize the tag and consequently not use the Open Directory Project or Yahoo! Directory title or description when listing that page in their results. The same now goes on Yahoo! for the NOYDIR tag.
If you want to use both tags and ensure that no major search engines (those that support these tags, that is) will not use directory titles and descriptions when displaying your page in their results it is easy to include them in your HTML documents.
Simply include the following line in the <head> of your document:
<meta name="robots" content="NOODP, NOYDIR">
