Bing and Yahoo adopt the canonical tag

After the announcement last year that the 3 major search engines would adopt the canonical tag, it seems that Bing and Yahoo may be about to support it too, though not to the cross-domain level that Google plan to.

This tag helps solve the duplicate content issue, particularly prevalent when multiple URLs point to identical content eg when tracker URLs are used, or dynamic pages are created from search criteria.

If you are going to use it, make sure you don’t try to come up with methods to con the search engines and follow the guideliens carefully on its usage. It could help your SEO immeasurably, especially for top landing pages rather than similar product pages that just make your analytics task that much harder.
