CTR Calculator
Click-through rate is the truest test of whether your message earns attention. Enter clicks and impressions to get your CTR, then pick a channel to see how it stacks up against the benchmark that actually applies.
CTR (click-through rate) = clicks ÷ impressions × 100%. It measures the share of people who saw your ad, listing, or email and clicked — the cleanest signal of message relevance. There is no single ‘good’ CTR: a strong paid-search CTR sits near 3–6%, while display CTR is often under 0.5%. Judge CTR against its channel, and remember a high rate on tiny reach can be noise rather than success.

How to use this calculator
- Gather clicks and impressionsPull both from the same report and period. For email, decide whether your CTR is clicks over delivered or clicks over opens, and be consistent — the two give very different numbers.
- Read the rateCTR is the percentage of viewers who clicked. The headline number is comparable over time within a channel, which is where its diagnostic power lives.
- Pick the right channelChoose the channel so the verdict uses the correct band. Comparing a display CTR to a search benchmark will make a perfectly normal result look like a failure.
- Diagnose, do not chaseA low CTR points at relevance: headline, offer, creative, or audience. Treat CTR as a clue to what to test, not a target to inflate with clickbait that tanks conversion.
- Export the resultCopy a share link, pull the CSV for your reporting, or print a one-pager for the creative review.
RGM Expert Says
We use CTR as the fastest relevance signal in the stack. Before we touch bids or budgets, CTR tells us whether the message is landing — a weak click-through rate almost always means the headline, offer, or audience is off, and no amount of bidding fixes a message nobody wants to click. It is the first thing we read in a creative test because it moves quickly and points straight at the hook.
The discipline we enforce is benchmarking CTR to its own channel and never across channels. Clients routinely panic at a 0.4% display CTR until we show that it is normal for display and alarm at a 1% search CTR that is genuinely weak. The channel selector in this tool exists for exactly that reason: the same percentage can be excellent or poor depending entirely on where it was earned.
Our biggest caution is the CTR-quality trap. It is easy to lift CTR with sensational creative or vague promises that pull clicks from people who immediately bounce — you win the metric and lose the campaign. We always read CTR alongside conversion rate and cost per acquisition, because the goal is qualified clicks, not just more of them. A slightly lower CTR that converts far better is usually the better outcome.
How it works
CTR divides clicks by impressions and expresses the result as a percentage. The verdict then compares that percentage to a typical band for the channel you select, since benchmarks differ by an order of magnitude across placements.
- Clicks — clicks on the ad, listing, link, or email.
- Impressions — times the item was shown (or emails delivered / opened, per your definition).
- Channel — sets the benchmark band the verdict uses.
Email CTR has two common definitions: clicks ÷ delivered (CTR) and clicks ÷ opens (click-to-open rate). Pick one and stay consistent. See RGM’s CTR deep dive.
Why CTR is a relevance gauge, not a goal
CTR is the purest measure of whether a message deserves attention, which is also why it is so easy to abuse. Clickbait, sensational creative, and overbroad promises all lift CTR while poisoning everything downstream — the clicks arrive, then bounce. The teams that use CTR well treat it as a relevance signal that tells them what to test, and they always pair it with conversion rate so a higher CTR has to earn its keep in outcomes, not just clicks.
Benchmarks only mean something within a channel. Public data puts average paid-search CTR in the low-to-mid single digits (often cited near 3–6% on Google Search), display frequently under 0.5%, paid social around 1–2%, and email CTR commonly 1–3% of delivered. Compare a number to the wrong channel and you will draw the wrong conclusion every time, which is why this tool asks you to pick one.
Finally, watch the denominator. A 10% CTR on 50 impressions is five clicks — statistically meaningless. CTR earns trust only at adequate volume, and small-sample CTRs swing wildly. Read the rate next to the raw clicks and impressions, and give a test enough reach before you crown or condemn a piece of creative on its click-through rate.
Average CTR by channel
CTR norms differ by an order of magnitude across channels, so these public averages exist to be compared like-for-like. Pick the matching channel in the calculator for an accurate verdict.
| Channel | Typical average CTR | Note |
|---|---|---|
| Google Search (paid) | ~3% to 6% | High intent; varies by industry |
| Display / GDN | Often under 0.5% | Low intent, vast reach |
| Paid social | ~0.9% to 2% | Driven by creative and audience |
| Email (clicks / delivered) | ~1% to 3% | Click-to-open rates run higher |
What the experts say about clicks
A high click-through rate on the wrong promise is a trap. Earn the click with relevance, then make the page keep the promise.
Clicks are interest, not value. Measure what happens after the click before you celebrate the click itself.
