At first I started marketing with my direct website splash page and the scores were below 7, but then I wanted to see how my blogspot site would do just out of curiosity. I put the blogspot site in the ad in place of my direct website and low and behold my quality scores shot up to 7 and above, some 10's for keywords I am currently using. Now I didn't start with a bunch of post or backlinks. I just set up a website blog that had original content that I add to periodically that was directly related to my keywords, and since I was using a trusted site like blogspot.com, it help kick my scores up, which means less cost for clicks and great exposure. So start a blog website or similar with a trusted site and ad your content and subject matter that directly relates to the keywords and you just might find yourself with a great quality score for your website with minimal work by search engine masters Google.
