Yahoo and Google squabble over size.
Excellent article by Danny Sullivan on this topic – Screw Size! I Dare Google & Yahoo To Report On Relevancy — Quote from the article…
I cannot believe we’re going through this again. This is Search Engine Size Wars VI, by my count. It’s absurd. It’s annoying. It’s a friggin’ waste of time. Instead of advancing to a commonly accepted relevancy figure, the search engines want to keep us mired in the mud of who’s biggest.
