From a dialog with one complainer to Google it was quoted about ad/content ratio:
“The site must have user value other than providing ads. For example, Google provides web search, news sites provide regularly updated original content, and other services. To check that your website complies with our arbitrage policy:
1. Open the site in a new browser.
2. Expand the browser to a minimum of a 1024 x 768 pixel display.
3. Make sure you have minimal browser menus and your font is set to medium or normal.
4. Scroll to the very top of the page, as evaluation is based on what appears above the fold.
5. The site is considered compliant if the area of ads is less than or equal to the area of content.
“Please use the instructions above to evaluate your entire website and, if necessary, bring it into compliance with our arbitrage policy. If you’re not in compliance, you may receive a low landing page quality score, which can negatively affect your Quality Scores, cost-per-clicks, and ad positions.”
