Optimization is the best way to increase your keyword's performance without raising costs. If your Quality Score is low, you may be using keywords, ads, or landing pages that aren't as targeted or relevant as they could be. This can mean higher cost-per-clicks and a potentially poor return on your investment.
To find out what needs improvement, visit the 'Keywords' tab in your account and open the Keyword Analysis field.
