What it means: CTR is the percentage your ad gets clicked compared to the number of people who saw your ad.
How do you determine a successful CTR? A typical campaign starts with a CTR of 1-2%. By adding negative keywords at the start of the campaign, and then constantly reviewing and eliminating irrelevant search terms people are using when they see your ads, Respage clients typically start with a higher CTR, and that CTR typically increases as time goes on. However, it's important to keep in mind that seasonality can affect CTR from time to time. If you're CTR is increasing over time, you're in good shape.
