Strange AdWords going on...

I sell a program. Let's call it Photoshop even though it's not Photoshop.

I run the same ad against two keywords [Photoshop] and [Photo Shop] as exact matches.

I've been crunching some numbers and Google mysteriously reports that in the last 30 days there were approx. 9000 impressions for [Photoshop] and 1200 impressions for [Photo Shop]. But in the previous 30 days there were 8000 impressions for [Photo Shop] and 1000 impressions for [Photoshop].

This makes no sense to me at all. I've made no other changes to my campaign, bid, keywords, etc. Ad position has stayed the same. CTR has stayed the same. The product is long in the tooth and there has been no recent ad campaign designed to sway the spelling of the product.

It's as if 80% of the searching public changed the way they spell an item; but there appears to be no rhyme or reason to it.

Or it's as if Google is tracking it wrong. Any thoughts?

If you are doing broad matching then it could be the bid for one was making more for Google and you had the word from there but was the other

As AussieWebmaster says, if you have the same terms (or similar terms) in the ad group as broad match, this could affect the impressions for the exact matches. Do you?
