While we normally don’t comment on market share fluctuations that occur in places other than America, some recent changes in the UK may bear mentioning.  According to the AT Internet Institute, Google’s share of the search market slipped by 1.6 percent between January and February.

That’s a significant amount.  Indeed, as the slightly upsized figure below shows (sorry for any blurriness), if Ask and AOL had suffered similar losses, they’d have been wiped out, hitting zero.

Of course, that didn’t happen.  Instead, both Yahoo and Bing benefited from Google’s dip.  Yahoo gained a not-bad 0.6 percent, and Bing increased its share by an even-better 0.7 percent.

Google’s still in an extremely dominant position, but given that Microsoft’s about to spend $2 billion on Bing commercials in the UK, these changes are noteworthy.  Microsoft might not be throwing its money away, as some people have speculated; there’s now the possibility that it could extend or accelerate this growth trend.

We’ll be sure to write again about the UK search market next month if anything out of the ordinary happens.  In the meantime, it should be interesting to see how those Bing commercials are received.
