How to use it

Using the ctr calculator

  1. 01

    Pull both numbers from one report

    Use your ad platform’s totals for a single campaign or date range so the ratio is meaningful.

  2. 02

    Enter clicks and impressions

    Raw counts only; nothing to convert.

  3. 03

    Benchmark the result

    Search ads often run 3–6%; display frequently sits under 1%. Compare within your channel.

Good to know

What CTR actually measures

CTR measures creative resonance; does this thumbnail, headline or offer make the right people act? It says nothing about what happens after the click; a high CTR with poor conversions usually signals over-promising creative.

Beware the low-volume trap

Two clicks on forty impressions reads as a spectacular 5%, but tiny samples swing wildly. Trust CTR comparisons only once impression counts reach the hundreds at minimum.

CTR interacts with CPC

On auction platforms like Google Ads, higher CTR raises quality scores and lowers what you pay per click. Improving creative literally buys cheaper traffic.

How it's calculated

The math behind this calculator

CTR = clicks ÷ impressions × 100

Click-through rate divides the clicks an asset earned by the number of times it was shown. We also express it as clicks per thousand impressions, which maps directly onto CPM pricing and makes small percentages easier to compare.

Assumptions & limitations

  • Both counts cover the same period, placement and audience.
  • Invalid or bot traffic is already filtered by the platform.
  • Zero clicks is a legitimate result, not an error.

Worked example

Fifty clicks on 10,000 impressions is a 0.5% CTR; five clicks for every thousand times the ad appeared.

FAQ

Frequently asked questions

What is a good CTR?
It depends entirely on channel and intent: Google search ads commonly achieve 3–6%, social feed ads around 1–2%, and display banners often below 0.5%. Judge against your own historical baseline first.
Why is my CTR falling over time?
Usually frequency fatigue; the same audience sees the same creative repeatedly. Refresh assets, expand audiences, or cap frequency to recover it.
Does CTR include accidental clicks?
Yes, platforms count them. Mobile display in particular accumulates fat-finger clicks, which is why reviewing downstream conversion data matters.
