# What is CTR

Definition:

CTR
is short for click-through rate. It is the ratio of the number of times a user clicks on an online ad to the number of viewers who see the website that has the advertising. For example, if one in 100 people who visit a specific website clicks on an ad and takes you to the advertiser’s site, then the CTR for that ad is 1/100 or %. The mathematical formula is CTR=clicks/impressions.

The CTR can be improved with creative ads that include a ‘call to action’ to incite the user’s curiosity, in addition to a careful and precise selection of keywords.

## How the CTR is calculated

Click-through rate or CTR indicates the measure of success an ad has had in capturing user interest. The higher the click-through rate, the more successful the ad has been in generating interest. Because internet users have become insensitive to ads on web pages, a typical click-through rate is found at only about two to three users per 1,000.

## What CTR values mean

A high click-through rate means that many users click on an ad, but it tells us nothing about the number of sales the ad ultimately generates. For this reason, the conversion rate, the percentage of clicks that lead to actual sales, can be a more useful metric of an advertising campaign’s success.

This indicator is one of the most important within any digital marketing strategy, since it offers a vision of the interest generated in users. It has a direct relationship with SEM positioning, and within this both with SEO and SEA,of which it is also part as a key indicator for example to increase the Quality Score of the keywords attacked. It is also a rate that must be taken into account in email marketing strategies to measure the effectiveness of each campaign.

It is therefore a metric that must be measured and improved regularly, to increase the chances of success in any digital strategy that is being developed.
