A few months ago we trimmed our Adwords account keywords down to the dozen keywords that both convert the best for us and had the highest quality scores in our account, typically 6/10. We’ve been advertising with these keywords for a few years now.
Sometime in the past month our quality scores for almost all of these terms has dropped to 3/10 and 4/10 causing our minimum bids to spike.
The problem is we rank first for about half of these keywords and at least top five for the bulk of the rest of them so problems with our landing pages doesn’t seem to make sense. The Adwords interface says there are no keyword relevanc, landing page quality, or landing page load time problems.
What/where should we look for the cause of this issue?
