I mean i understand what google wants on a "good" landing page, we know they want good navigation, relevant content, privacy policy etc. I'd also like to know whether there are certain, different factors shich specifically apply to german websites. I had two VERY nice keywords and a made a landing-page SEO optimized and certainly relevant for those keywords. I do NOT get those better than "poor" in adwords....and this makes me angry. Sometimes i just dont get google. I had other pages where i had "great" score for keywords which were not even on the page. Example: Say i had a page which sells Cheap Graphicscards. I dont have the term "cheap graphicscards" anywhere on the page, but i get "great" for this term. Another page i might have optimized for "Cheap Dogfood" and have that keyword in my page, NO KW-stuffing, nice H1, H2, relevant content....but i cant get "cheap dogfood" any better than "poor".....
I feel your suffering my brother. If its a new adgroup I keep deleting and re-adding just changing some wording until I get that magic "Great" (well, at least 3 trys anyway, then I give up) :-<
This may be a long shot but are you sure your DOMAIN has not been slapped itself and not just your campaign? A domain with poor quality score history will be "blacklisted" and always get a POOR QS regardless of what you do... getting it back is a major mission.... Just thought I would throw that out there just in case. Cheers Stewart
