Tim Mayer has stuck to his word and Yahoo Search has implemented support for a No Open Directory Project (DMOZ) tag.
Priyak Garg posts on the Yahoo Search Blog:
We strive to show the most useful information in search results. We look at multiple sources for titles and abstracts, including page content, anchor text in the links to a page, Yahoo! Directory and the Open Directory Project (ODP); and we pick the best based on our algorithms. You might have seen some of the features that we have implemented with this approach, such as quick links for Wikipedia, and local business data. However, some webmasters have had issues with titles and abstracts in ODP and have adopted the ‘NOODP’ META tag to indicate to search engines not to use them.
Yahoo recognizes the following META tags on web pages:
META NAME=”ROBOTS” CONTENT=”NOODP”
META NAME=”Slurp” CONTENT=”NOODP”
Garg adds :
If we find any of these tags on your page, we will not consider ODP titles or abstracts as candidates for your URL in search results. We are reindexing content on the web to launch this change. This will be accompanied by the usual ranking changes and page shuffling in the index that are typical of weather updates.
