Every time someone does a search that triggers your ad, Google calculates a Quality Score. To calculate this Quality Score, Google looks at a number of different things related to your account, such as:
- Your keyword’s past clickthrough rate (CTR): How often that keyword led to clicks on your ad
- Your display URL’s past CTR: How often you received clicks with your display URL
- Your account history: The overall CTR of all the ads and keywords in your account
- The quality of your landing page: How relevant, transparent, and easy-to-navigate your page is
- Your keyword/ad relevance: How relevant your keyword is to your ads
- Your keyword/search relevance: How relevant your keyword is to what a customer searches for
- Geographic performance: How successful your account has been in the regions you’re targeting
- Your ad’s performance on a site: How well your ad’s been doing on this and similar sites (if you’re targeting the Display Network)
