What is Click-Through Rate?
Click-through rate is the percentage of ad impressions that turned into clicks. It measures one thing precisely: how compelling your ad was to the people it was shown to. Because it sits at the very top of the funnel, it moves faster than any other metric — you can read a meaningful CTR signal within hours of launch, long before you have enough conversions to judge anything else.
Why it matters
- It's the earliest usable signal you get on new creative. A weak CTR after a few thousand impressions tells you the ad isn't landing before you've burned budget finding out via conversions.
- Google Ads folds expected CTR directly into Quality Score, so a higher CTR literally lowers what you pay per click on the same bid.
- A CTR that's dropping while impressions stay flat is usually frequency fatigue — the same people seeing the same ad until they stop noticing it.
The formula
CTR = (Clicks ÷ Impressions) × 100
- Clicks
- — number of times someone clicked the ad
- Impressions
- — number of times the ad was served (not unique people)
How to use this calculator
- 01Pick one ad, ad set, or campaign — a blended CTR across very different placements tells you almost nothing.
- 02Pull clicks and impressions for the same date range from your ad platform.
- 03Enter both numbers. The gauge compares your rate against typical paid-search and paid-social ranges.
- 04Compare CTR against the same ad's conversion rate — high CTR with low conversion usually means the ad promised something the landing page doesn't deliver.
Worked example
A search campaign served 48,000 impressions last month and earned 1,200 clicks.
- Clicks = 1,200
- Impressions = 48,000
- CTR = (1,200 ÷ 48,000) × 100 = 2.5%
2.5% is a respectable search CTR for a mid-intent keyword set. On paid social the same number would be exceptional; on branded search terms it would be disappointing. Context decides.
Industry benchmarks
Compiled August 2026
Google Search (non-brand)
2% – 5%
Rises sharply on branded terms — 10%+ is common.
Google Display
0.4% – 0.6%
Low by design; display is an impression channel.
Meta (Facebook / Instagram) feed
0.9% – 1.6%
Varies heavily by vertical and creative format.
LinkedIn Sponsored Content
0.4% – 0.6%
Lower CTR, much higher lead value in B2B.
Common mistakes
- Comparing search CTR to social CTR and concluding social is broken — they're different intent levels and the ranges are not interchangeable.
- Judging CTR on a few hundred impressions, where random variation swamps any real difference between two ads.
- Optimising for CTR alone — clickbait creative reliably lifts CTR while lowering conversion rate and raising cost per acquisition.
- Mixing placements in one number, so a strong feed placement hides a dead audience network placement.
How to improve your CTR
Match the ad to the search intent, not the product
The highest-leverage CTR fix in search is usually rewriting the headline to echo the query wording rather than describing your feature set.
Rotate creative before frequency kills it
On paid social, CTR decay is usually an audience seeing the same asset too often rather than a bad asset. Check frequency before you rewrite the ad.
Check your frequency threshold →Cut the placements dragging the average down
Break CTR out by placement and device. Excluding one weak placement often lifts blended CTR more than any creative change.
Frequently asked questions
What's a good CTR?+
It depends entirely on channel and intent. Roughly: 2–5% for non-brand Google Search, under 1% for display, and around 1% for Meta feed placements. Compare against your own history first — your last 90 days is a better benchmark than any industry average.
Does CTR affect how much I pay per click?+
Yes, on Google Ads. Expected CTR is one of the three components of Quality Score, and a higher Quality Score lowers your actual cost per click at the same bid. On most social platforms, higher engagement rates similarly lower delivery costs.
Why is my CTR high but conversions low?+
Usually a promise mismatch: the ad sets an expectation the landing page doesn't meet. It can also mean the ad is attracting the wrong audience — broad or emotive creative pulls curious clicks rather than buying intent.
How many impressions do I need before CTR means anything?+
As a rough floor, a few thousand impressions per variant. Below that, the difference between two ads is usually noise rather than signal.
