So, as described above, we take total value equals to 100%. For example, if you have 20 oranges (= 100%). If you ate five oranges, then in percentage, you have eaten 5/20 × 100% = 25% of your oranges and left with 75% oranges.

Average CTR (or average click-through rate ) is the ratio of ad clicks to impressions in your AdWords campaigns. While basic CTR measures the rate of clicks on each ad, average CTR calculates the amount of clicks vs. impressions across your campaign, or for each individual keyword.

A low ad CTR is problematic, as it can drag down your Quality Scores and affect future ad placement. Low CTRs signal a lack of relevance for your ad viewers, who aren’t inspired to click on your ad and visit your landing page to learn more about your offer or take the desired action.

On the other hand, a high average CTR – either across your campaign or for a specific keyword – doesn’t always mean success. It is one indicator that, when combined with other KPIs (key performance indicators) can point to the success of your campaign. However, high average CTRs with low conversions may actually mean that you’re wasting spend by attracting people less likely to convert. This may be caused by targeting that is too broad, irrelevant ad copy, or a combination of both.
