In brief
CTR (Click-Through Rate) is the percentage of people who click on your ad after seeing it. Formula: (Clicks ÷ Impressions) × 100. For Search campaigns a good CTR is 5-10%, tight niches reach 10-15%, and anything above 20% is the exception. The average sits around 2-3%. But remember: high CTR ≠ successful campaign.

Quick answer
What is CTR (Click-Through Rate)?
CTR (Click-Through Rate) is the percentage of people who click your ad after seeing it. Formula: CTR = (Clicks ÷ Impressions) × 100. In Google Ads, CTR is a major quality signal through Expected CTR. A good CTR for Search campaigns is 5-10% (the average sits around 2-3%), while Display typically averages around 0.5-1%.
What is CTR and why it matters
CTR (Click-Through Rate) is the percentage of people who click on your ad after seeing it. It's one of the most important quality signals in Google Ads.
Simply put: if 100 people see your ad and 5 click on it — your CTR is 5%.
Formula: CTR = (Number of clicks ÷ Number of impressions) × 100
Why CTR matters:
- Impacts Quality Score — Expected CTR is one of the three components of the quality rating (Google doesn't publish the weightings)
- Lowers CPC — higher CTR = higher Quality Score = lower cost per click
- Relevance signal — Google sees that users are responding to your ad
- More clicks for the same budget — better CTR means more efficient spending
Formula and calculation examples
The formula is simple, but understanding it in context is key.
| Impressions | Clicks | CTR | Rating |
|---|---|---|---|
| 1,000 | 20 | 2% | Average |
| 1,000 | 50 | 5% | Good |
| 1,000 | 100 | 10% | Excellent |
| 1,000 | 200 | 20% | Exceptional (rare) |
CTR benchmarks by campaign type
Benchmarks vary dramatically by campaign type. A 1% Display CTR is excellent, while for Search it would be poor.
The figures below are a reference point from the accounts I manage, not an official Google benchmark. Your real reference is the account benchmark in your own account and your own history.
Search campaigns
5-10%
The average is around 2-3%. In tight niches CTR reaches 10-15%, and above 20% is the exception — usually exact match on very specific queries.
Display campaigns
0.5-1%
Lower CTR is normal as these are awareness ads. Remarketing Display can be higher.
Shopping campaigns
0.7-1.5%
Depends on product and price. Premium products with good images have higher CTR.
YouTube campaigns
0.5-2%
Skippable ads have lower CTR. Non-skippable and bumper ads are measured differently.
Important: Branded vs Non-branded
Always separate branded from non-branded campaigns. If your non-branded campaigns have unexpectedly high CTR (e.g., 25-30%), you probably haven't removed branded search terms. That's not a sign of success — it's a structural mistake.
Case Study: AnkiBuddy — from 6-8% to 20% CTR
From my experience
Due to NDA agreements, I cannot share financial metrics, but I can explain the strategy and approach. This demonstrates that I'm a serious partner who respects client confidentiality.
AnkiBuddy is an EdTech SaaS platform that uses AI to automatically generate Anki flashcards from lecture PDFs. The primary market is medical students in the DACH region (Germany, Austria, Switzerland).
Challenge
When I took over the account, Search campaigns had an average CTR of 6-8%. For a SaaS with narrow targeting, this wasn't bad — but I knew it could be better.
Strategy
- Highly specific keywords — focused on terms medical students actually use when searching for study tools
- Pain points in headlines — emphasized problems students face (time, volume of material, exam preparation)
- Benefits over features — instead of "AI generates cards" → "Save 10 hours weekly on creating flashcards"
Result
CTR: up to 20%
From the initial 6-8% on Search campaigns, we achieved over 20% CTR for the best Ad Groups. The key was understanding the exact needs of the target audience.

5 common mistakes that kill CTR
On most accounts I take over — even those with monthly budgets of €5-10k — I see the same mistakes.
Mistake #1
Generic headlines without benefits and numbers
Solution: Add specific numbers ("Repairs from $50"), questions ("Looking for a plumber?") and urgency ("Available today").
Mistake #2
Too few assets (formerly extensions), or none at all
Solution: Use all available assets — sitelinks, callouts, structured snippets, call asset (mandatory for services). Assets take up more space in the result and give more reasons to click. How much CTR improves depends on the account, so don't count on a fixed percentage.
Mistake #3
Broad match without control
Solution: Use narrower match types (phrase, exact) or if using broad — add an extensive negative keyword list and regularly review the Search Terms Report.
Mistake #4
Not separating branded from non-branded
Solution: Create a separate branded campaign. Add your brand as a negative keyword in non-branded campaigns. This gives you accurate insights into CTR for both categories.
Mistake #5
Not testing ads
Solution: Have a minimum of 2 RSA ads per Ad Group. Test different descriptions, sitelinks, or completely different approaches. It depends on the client and industry.
How to diagnose low CTR (3 steps)
When CTR drops or is low from the start, here's my diagnostic sequence:
Search Terms Report
First check if the queries are relevant. If you're getting clicks for irrelevant searches, CTR will be low because the ad isn't meant for those people. Add negative keywords.
Ad Copy analysis
Review headlines and descriptions. Are they generic? Do they have numbers, questions, urgency? Do they communicate WHY to buy? Rewrite ads with clear benefits.
Auction Insights
Look at the competition. If your Impression Share dropped and competitors added new ads, you might need a more aggressive approach or better bidding.
7 ways to improve CTR
Tactic #1
Headlines with numbers
"Repairs from $50" or "Delivery in 30 minutes" attract more attention than generic headlines.
Tactic #2
Headlines with questions
"Looking for a plumber?" or "Need an auto mechanic?" directly address the user's need.
Tactic #3
Headlines with urgency
"Available today", "24/7 service", "We arrive in 30 min" — urgency drives action.
Tactic #4
Sitelinks to sections
Instead of generic links, link to specific sections of the landing page. This helps users get to the desired information faster.
Tactic #5
Industry-specific callouts
For some industries, pain points work ("No hidden fees"), for others benefits ("Free shipping"). Test both approaches.
Tactic #6
Call asset for services
Mandatory for all service businesses. Direct calls from ads increase overall engagement and conversions.
Tactic #7
Pinning only when you must
Pin a headline only when the message has to show: a regulatory disclaimer or a mandatory brand line. Otherwise let Google combine. Pinning cuts the number of combinations the algorithm can test and lowers Ad Strength. More detail in the RSA guide.
When low CTR is actually OK
Low CTR isn't always a problem
- Display remarketing — expect 0.5-1%, the goal is reminding, not immediate clicks
- Brand awareness campaigns — the goal is brand visibility, not clicks
- Competitive industries — some sectors have naturally lower benchmarks (e.g., insurance, finance)
- Top-of-funnel YouTube — video ads for broader audiences have lower CTR because the goal is reach
The key is understanding the campaign goal. If the goal is brand awareness, a 0.3% CTR on the Display network may be perfectly fine. But if the goal is lead generation on Search, a 2% CTR is a signal for optimization.
MYTH: "High CTR = successful campaign"
This is FALSE
High CTR means people are clicking on the ad. But it DOESN'T mean they're buying, calling, or sending inquiries. You can have 20% CTR and 0 conversions. CTR is only one part of the equation.
This is the most common myth I hear from clients. "We have great CTR, but no results" — because CTR measures only the first step (click), not the final goal (conversion).
Example: A campaign with 20% CTR and 0 conversions is worse than a campaign with 5% CTR and 10 conversions. Always look at the complete picture: CTR + Conversion Rate + CPA/ROAS.
