AdWords Quality Scores
AdWords uses “Quality Scores”to determine where an ad will rank. The higher your
Quality Score is, the higher your ads will rank. AdWords also has Quality Scores to
determine distribution on the content network and to calculate the minimum bid
required to compete in an auction on the search network. The search network and the
content network comprise the Google network. In some cases, data used in Quality
Scores is pulled only from Google and not the Google network. According to Google,
this is how Quality Scores are used (https://adwords.google.com/support/bin/answer.

• The keyword’s CTR on Google; the CTR on the Google Network isn’t considered
• The relevance of the keyword to its ad group
