Yahoo! uses a variety of sources for information on your pages to dynamically construct meaningful descriptions (abstracts) and titles that assist users in understanding your page.

These sources include, but are not limited to: text on the page, the page's Meta description, and editorial descriptions from the Yahoo! Directory and third parties. The abstract can change depending on the search terms entered. Changing the content on your page and the metadata can influence the abstract.

ODP Titles and Abstracts
To remove ODP titles and abstracts as candidate title and abstract for one or more of your URLs, use one of the following Meta tags on your pages:

<META NAME="ROBOTS" CONTENT="NOODP">

   or

<META NAME="Slurp" CONTENT="NOODP">

When we find any of these tags in the Meta data of your web document, Yahoo! Search will not take ODP titles or abstracts into consideration when presenting the title and description for that URL in search results.

Yahoo! Directory Titles and Abstracts
To indicate that Yahoo! Directory titles and abstracts not be considered in web search results, use the "NOYDIR" Meta tag.

Yahoo! Slurp recognizes the following Meta tags on your pages:

<META NAME="ROBOTS" CONTENT="NOYDIR">

   or

<META NAME="Slurp" CONTENT="NOYDIR">

When we find any of these tags in the Meta data of your web document, Yahoo! Search will not take Yahoo! Directory titles or abstracts into consideration when presenting the title and description for that URL in search results.

Note: A web page URL may show in search results without an abstract. A URL may be included in Yahoo! Search Technology as a "thin" document with no text content. Links and reference text from other public web pages may provide identifiable information about a URL and may be indexed as part of web search coverage.
