Yahoo! has finally released a no Yahoo! directory meta tag much like the no ODP meta tag.
Yahoo! Search Blog comments:
We’re adding support for the Meta tag called ‘NOYDIR’ that will complement the ‘NOODP’ Meta tag, which we already support. If you’re unfamiliar, the ‘NOODP’ Meta tag is basically a way for webmasters to indicate that Open Directory Project (ODP) titles and abstracts will not be used in search results for their pages.
Many of the webmaster used to complain that the title and description given to search listing when a website was added in the Yahoo directory impacted click through ratios and rankings. Now they can simply opt out of Yahoo! By making use of directory information.
The format for the meta tag is:
<META NAME=”ROBOTS” CONTENT=”NOYDIR”>
<META NAME=”Slurp” CONTENT=”NOYDIR”>
