More than a year since the three major search engines united to announce the canonical tag, neither Bing nor Yahoo formally support it. But that could be changing soon.

Speaking during the “Ask the Search Engines” session at SMX West on Thursday, reps from both search engines said they’re in the process of supporting rel=canonical right now.

Bing’s Sasi Parthasarathy told attendees that canonical tag support should be in place by the end of March or early April. Arnab Bhattacharjee of Yahoo said they’re currently rolling out support of the tag, but cautioned that Yahoo will only use it “as a hint” regarding a web page’s original/primary URL.

Back in October, Google went a step further and announced its support of the canonical tag across different domains. On Thursday, Parthasarathy said Bing has no current plans to follow suit, while Bhattacharjee said Yahoo is exploring the possibility of cross-domain canonical tag support.
