Hi,
I noticed very recently that keywords containing competitor names (in particular one multinational company) have suddenly had a drop in quality score from 3.0 to 1.0. Nothing has been changed to the ad group at all or the website the ads are linked to. The quality scores were always quite low (unsurprisingly) but the ads still got a reasonable amount of clicks and conversions, with ad positions averaging 1.x. Now I'm seeing that ads for these keywords are 'Rarely shown due to low quality score' and first page bids have risen dramatically.
Has there been a change of policy by Google over this? Or is the company in question twisting Google's arm?
Any comments or help will be appreciated.
