Why It’s Important?

CTR is the most important factor used to calculate the Quality Score assigned to the keywords you are bidding on within your Pay-Per Click (PPC) account (for more information about Quality Score, see my past blog article on the subject).

Quality Scores play a major role in determining how much you pay for a click (Actual CPC) on your ad.

What’s a Good CTR?

This depends on what you are trying to accomplish, but a general rule of thumb is anything over 2.00% is a good CTR.

The Bottom Line

Improving your CTR will improve your Quality Score and this will lower your PPC costs!
