I started an adwords campaign for a gift basket business with 20 obvious keywords (KW); result was a few thousand impressions a day for 30-40 clicks/day. (CTR around 0.5-1%). Then I followed the advice in Perry Marshall's book and elsewhere about expanding the number of KWs. I found another 50 or so on Overture, e.g. "wedding gift", etc, etc --> I added lots of expressions, phrases, in brackets, as opposed to single words.
Guess what happened: number of impressions collapsed to a few hundred a day, and CTR almost nil (1-3 clicks a day for 3 days now). Almost as if adding lots of phrases with "gift" had penalized me. Indeed, the word "gift", perhaps a bit general, had done well until these modifications - Now it has zero impressions!
So I get shut down, with the dire warnings about nonperforming keywords - But status is still "high" or "average" for all of them!
I had also changed the ad - but can a bad ad cause a drop in impressions?
How on earth can the number of impressions collapse when I add KWs? Should I remove some? Can changing the ad help?
Many thanks for any thoughts
