The Yahoo! Search blog announced earlier today that they have finally added support for the NOYDIR meta tag. Yahoo! already supports the NOODP tag that was instituted a few months back to prevent DMOZ descriptions from displaying in the SERPs.
If you have a listing in the Yahoo! directory and are not happy with the directory description showing as a snippet in search results you’ll be able let Yahoo! know not to use it as the abstract. Yahoo! has provided two tags to prevent your directory description from showing.
<meta NAME="ROBOTS" CONTENT="NOYDIR">
<meta NAME="Slurp" CONTENT="NOYDIR">
From the search blog:
For pages with this tag, we will not use Yahoo! Directory titles or abstracts for your URL in web search results.
Yahoo! Weather Report
As part of the new NOYDIR tag Yahoo! is re-indexing content so the new tag can take effect. Expect to see Yahoo! visiting your site soon as well as some ranking changes and shuffling as is typical with Yahoo weather updates.
The changes should be happening now in the U.S., Japan, and Korea, and will be rolled out in other areas in the future.
Since I congratulated Google and MSN when they first adopted NOODP I’ll congratulate Yahoo! for the new NOYDIR tag. I’d still like to see them address the issue of displaying SERP titles based on the anchor text of links pointing to a page though.
