What is CTR

Full name: Click-Through Rate

Also known as: click-through rate, clickthrough rate

Definition

CTR (click-through rate) is the share of ad impressions that ended in a click: clicks divided by the times the ad was shown. It shows if the ad earns the click.

Why it matters

CTR is the first check on an ad: if people do not click, nothing after the click can work.

Common mistakes

Judging an ad by CTR alone, while the ad with fewer clicks brings the same number of chats.

Two Meta ads for a fictional pilates studio

A fictional neighbourhood pilates studio tests two Meta ads before its ad month, 2,000 impressions each.

  1. Formula

    CTR is link clicks divided by impressions, times 100.

  2. Ad A

    "Small group pilates, 10 minutes from home" got 20 link clicks.

    20 ÷ 2,000 = 1%

  3. Ad B

    "First class free for everyone!" got 80 link clicks. The "free" is the fictional ad's promise, not a price.

    80 ÷ 2,000 = 4%

  4. After the click

    Ad A's 20 clicks opened 4 WhatsApp chats, and ad B's 80 clicks opened 4 chats too.

    4 ÷ 20 = 20%, 4 ÷ 80 = 5%

  5. Decision

    The studio runs ad A: the same chats from fewer clicks, from the people the ad was written for.

Four times the clicks, the same four conversations. CTR tells you the ad was clicked, not that it found the right people. The first picture below is a separate approximate example with round numbers of its own, the second draws this test.

Illustration

From impression to purchase

  1. 1,000Impressions

  2. ↓ ⁨3%⁩ of impressions

    30Clicks

  3. ↓ ⁨10%⁩ of clicks

    3Purchases

Of ⁨1,000⁩ impressions, ⁨30⁩ ended in a click, a CTR of ⁨3%⁩. Only ⁨3⁩ of those clicks became purchases: CTR shows the ad was clicked, and the sale is counted at the next step.

A separate approximate example with round numbers, not the studio's ad test above: an ad shown 1,000 times, clicked 30 times, with 3 purchases after the click.

Two ads, the same four chats

Ad A

"Small group pilates, 10 minutes from home"

2,000 impressions

CTR 1%

4 chats from 20 clicks, 20%

Chats per 1,000 impressions: 2

Ad B

"First class free for everyone!"

2,000 impressions

CTR 4%

4 chats from 80 clicks, 5%

Chats per 1,000 impressions: 2

Gold is the CTR, the ad's pull. The bottom line is CTR times the share of clicks that open a chat, the number that decides between the two ads.

Ad B's CTR is 4 times ad A's, yet both open 4 chats: 60 more clicks and not one more chat. Per 1,000 impressions both bring 2, because ⁦1% × 20%⁩ is the same as ⁦4% × 5%⁩. Paid per click, ad B's chats would cost 4 times as much.

Invented numbers from the worked example. Whether more clicks cost more depends on how the ad is paid for, per click or per 1,000 impressions.

The studio's ad test from the worked example: two Meta ads, 2,000 impressions each. One square is one link click, green when the click opened a WhatsApp chat.

Definition

CTR counts how often an ad that was shown was also clicked. Google Ads defines it as clicks divided by impressions, and an impression is one showing of the ad, so a person who saw the ad three times counts three times. CTR measures the ad and its audience, not the sale: it says whether the picture and the first line made people act, and nothing about what happened after the click. On a click-to-WhatsApp ad the click opens a chat, so the next number to read is how many chats started, not website conversions. Meta's reports show more than one CTR, one of them named CTR (all), so check which clicks a column counts before you compare two ads.

Why it matters

On Google search ads, expected CTR is one of the three parts of Quality Score, next to ad relevance and landing page experience, and Google calls Quality Score a diagnostic tool, not an input in the ad auction. A high CTR is good news only when the clicks turn into chats and bookings, which is why it is always read next to the conversion rate and the cost per click.

Directly related: CPC, Conversion Rate, CPL.

Formula

CTR = (Clicks / Impressions) * 100

CTR in Google search results

Search Console shows the CTR of your own site in Google Search: clicks divided by impressions, where an impression is your page appearing in someone's results. The rate depends heavily on position, because a result further down the page gets fewer clicks from the same impressions, so compare a page's CTR with pages at a similar position, not with the site average.

A page that already ranks on page one and still earns few clicks is a title and description question. Google's own guide to the Search Console bubble chart says the same: make the title and the meta description descriptive, specific and accurate, and check whether competing results show rich results that draw the click.

CTR in email and newsletters

In email, the click rate usually means the share of delivered emails that registered at least one click: clicks divided by delivered emails. Some tools also show a click to open rate (CTOR), which divides unique clicks by unique opens, so the same campaign can show two very different numbers.

Before comparing two campaigns, or your number with one from another tool, check which of the two the report shows. As with ads, read it next to what happened after the click: replies, bookings and orders.

Improvement tips

  • Compare your own ads with each other, on the same audience and period, instead of with benchmark numbers from the internet.
  • Write the first line for the person you want, even if it draws fewer clicks: the wrong clicks cost money and bring no chats.
  • On Google, look at the expected CTR part of Quality Score for each keyword to see which ads need a clearer first line.
  • On Meta, compare ads on the clicks that take people to your site or to WhatsApp, not on every click on the ad.
  • Write next to each ad how many chats or bookings it brought, and read CTR together with that number.

Common mistakes

  • Comparing a CTR that counts every click on the ad with one that counts only clicks to the site or WhatsApp.
  • Writing a promise that draws curious clicks from people who will never buy.
  • Comparing the CTR of a search ad with that of an ad in a feed: people who search already want something, people who scroll do not.

CPC

CPC (cost per click) is what you pay on average for one click on your ad: ad spend divided by clicks. A cheap click does not mean a cheap customer.

MarketingBeginner

Conversion Rate

Conversion rate is the share of people who took the step you count, such as booking or buying, out of those who reached the stage before it, like clicks.

MarketingIntermediate

CPL

CPL (cost per lead) is what you pay on average to get one lead, a person who left details or wrote to you: ad spend divided by the leads it brought.

Vanity metrics

Vanity metrics are numbers that look impressive, like followers, views or total sign ups, but do not tell you what to do next or whether sales are growing.

Frequently asked questions

What does CTR mean in plain words?
Out of every 100 times your ad was shown, how many times someone clicked it. An ad shown 1,000 times with 10 clicks has a CTR of 1%.
Do I need to know CTR before I run my first ad?
It helps to know what you will look at. In the first days of a campaign CTR is the earliest signal you get, before any chat or booking arrives, so it tells you quickly whether an ad is being ignored.
What is a good CTR?
No number fits every business. CTR depends on the platform, the audience and the offer, and a search ad, shown to people who are already looking, can differ a lot from an ad in a feed. The useful comparison is between your own ads, on the same audience and period.
Why does my Meta report show more than one CTR?
Meta's reports offer more than one click count, and one of the CTR metrics is named CTR (all). Before you compare two ads, check which clicks the column counts, and compare them on the clicks that take people to your site or to WhatsApp.
My ad has a high CTR but few chats. What is wrong?
Either the ad draws the wrong people, or the step after the click is broken. Check whether the promise in the ad matches what people find after the click, and whether the page or the chat answers their first question fast.
Does Google care about my CTR?
Google uses expected CTR as one of the three parts of its Quality Score, which it calls a diagnostic tool and not an input in the ad auction. So a low expected CTR is a sign that the ad does not match the search, and the answer is to fix the ad.
What comes after the click on a click-to-WhatsApp ad?
A chat. The click opens WhatsApp, so the next numbers to count are how many conversations started and how many were answered, not visits to a website.
How do I raise CTR without drawing the wrong people?
Name who the service is for and one concrete detail in the first line, such as the place or the format. A sharper promise may bring fewer clicks from people who are not a fit and more from people who are.
How often should I check CTR?
In the first days after an ad starts, and then weekly. On 200 impressions one click more or less moves CTR by half a point, so let each ad be shown enough times before you decide.
Is CTR the same as conversion rate?
No. CTR measures the step from seeing the ad to clicking it. Conversion rate measures a later step, such as from a click to a chat or a booking. An ad can do well on one and badly on the other.
Do I need an analyst or special software to track CTR?
No. Meta Ads Manager and Google Ads show CTR for every ad. What you add yourself is the count of chats or bookings each ad brought, so you can read the two together.
Can I ignore CTR if the ads already bring customers?
Customers are the number that counts most, but CTR is the earliest number you get. A sudden drop on an ad that used to work is a reason to check the ad and its audience before the month's results arrive.

After I finished a cosmetology course at a leading company, I was confused. I didn't know how to open a business, what to sell from home, or how to bring in clients. Since I reached out to Mobius, everything has changed. We built an organized plan with clear steps and no unnecessary risks. Today I see results, and I'm growing and developing every month.

When I finished a massage course, I imagined a different world. I found out it's a hard field, and financial stability isn't easy to find. When I came to Mobius, something changed. We started an organized process and built a business plan. Without Mobius? I probably would have given up. Today I believe in myself and in my own path.
