CTR (Click-Through Rate, click-through rate) — shows the percentage of users who clicked an ad after seeing it.
For example, an ad was shown 10 000 times and received 200 clicks. The CTR will be 2%.
CTR helps evaluate how well an ad attracts the audience’s attention. If one creative receives noticeably more clicks than another under similar launch conditions, this may indicate a more effective visual, headline, or offer.
How to calculate CTR
Formula:
CTR = Number of clicks / Number of impressions × 100%
For example, an ad received 50 000 impressions and 1 500 clicks:
1 500 / 50 000 × 100% = 3%
The CTR was 3%. This means that every 100 ad impressions generated an average of three clicks.
What CTR depends on
Ad click-through rate may be affected by:
-
the creative and its opening hook;
-
the headline and text;
-
the offer itself;
-
the CTA;
-
the audience and targeting accuracy;
-
the ad format and placement.
Therefore, there is no universal «good CTR». Normal values differ depending on the traffic source, format, GEO, niche, and even the specific placement.
A high CTR does not always mean a good result
CTR only shows how actively users click the ad. This metric does not account for what happens after the click.
For example, a creative with a bold promise may generate many clicks and a high CTR, but after clicking, users do not find what was promised on the landing page and leave. As a result, there are few leads, while the CPA is high.
The opposite can also happen: the CTR is lower, but the ad attracts a more targeted audience that converts better after clicking.
Therefore, CTR should be considered together with CPC, CR, CPA, and other funnel metrics. A high CTR alone does not mean that the campaign setup is profitable.
