In a blog post this afternoon, Google’s Amit Singhal reiterates the claims we reported this morning that Bing is copying Google’s search results. But he also goes a step further, or perhaps a couple steps, and accuses Bing’s search results of being “a cheap imitation” of Google’s.

Put another way, some Bing results increasingly look like an incomplete, stale version of Google results – a cheap imitation.

Singhal goes on to say that Google wants Bing to stop what it’s doing — namely, using customer search data from Google searches to influence search results on Bing.

He labels Bing’s search results as “recycled,” and makes a plea for users to stop using Bing and use Google, instead.

We look forward to competing with genuinely new search algorithms out there—algorithms built on core innovation, and not on recycled search results from a competitor. So to all the users out there looking for the most authentic, relevant search results, we encourage you to come directly to Google.

In the end, it seems that one conclusion we can draw from all of today’s events is this: Despite its continued dominance of the search landscape, Google is very concerned about Bing’s recent gains and is taking the competition very seriously … and perhaps with the gloves off now, too.
