What is CTR? Click through rate as a measure of relevance

Work out the click through rate of your ads from clicks and impressions — and see where it sits against Google Search, Display and Shopping benchmarks.

Your click through rate (CTR) measures what share of the people who saw an ad or a search result actually clicked it. It is the first honest signal you get about whether a creative or a headline is relevant — long before conversion rate and cost per acquisition have anything to say. A high CTR means the ad copy and the targeting match what the audience was looking for.

Click through rate formula: clicks over impressions, times 100

CTR (%) = clicks ÷ impressions × 100

How to calculate CTR, and what 2 % actually looks like

A Google Search campaign returns 1,200 clicks on 60,000 impressions:

CTR benchmarks by channel — and what counts as a good click through rate

Benchmarks by channel and network. Well-tuned search campaigns reach 8–12 %, which is not a category of its own but the top end within Google Search:

International benchmarks. Click-through rates describe behaviour rather than price — that search ads outperform display banners holds across markets.

A channel comparison only takes you so far. CTR on its own says nothing about profitability — it has to be read alongside conversion rate and cost per click, because a rate that beats the benchmark while the traffic never converts is an expensive kind of success. On reach buys it is also the bridge to the click price: cost per mille and CTR together give the effective CPC, which the CPM calculator reports next to the CPM itself.

What a higher click through rate is actually worth

Clicks rise linearly with CTR: at the same reach, every additional percentage point buys you impressions ÷ 100 extra clicks. The chart above is that straight line; enter a target CTR and the calculator works out the gain at an unchanged budget. With large impression counts the leverage is considerable — moving from 2 % to 3 % on 60,000 impressions is 600 more clicks without spending another cent.

How to improve CTR: ad copy, extensions and targeting

• Put the keyword in the headline: when the searched term appears in bold in your title, CTR rises noticeably — relevance is recognised in a fraction of a second.
• Use strong calls to action: «Buy now», «Start a free trial» or «Order today» create urgency and raise the probability of a click.
• Add ad extensions: sitelinks, callouts and structured snippets visibly enlarge the ad and give it more clickable surface.
• Test systematically: run headlines and descriptions against each other. Small differences in wording can double CTR — always measure within the same auction.
