Outbound CTR

Outbound CTR is the percentage of impressions that led to an outbound click, a click that takes someone off Facebook or Instagram to your website or app. It measures how well an ad sends traffic to your store.

Also called: outbound click-through rate, outbound clicks CTR, CTR (outbound), unique outbound CTR

Formula

Outbound CTR = outbound clicks ÷ impressions × 100

600 outbound clicks from 50,000 impressions = an outbound CTR of 1.2%.

Outbound CTR shows how often an impression turns into a click that leaves Meta's apps and lands on your property, usually your website or app store page. For an online store, it is the click-through rate that tracks closest to actual store traffic.

Metric Clicks counted What it tells you
CTR (all) Every click, including likes, comments and profile taps General engagement, often inflated
CTR (link click-through rate) Clicks on links, including destinations inside Meta Interest in the ad's call to action
Outbound CTR Clicks that take people off Meta Traffic to your site or app

When your ad links straight to a website, link CTR and outbound CTR are usually close. They drift apart when the ad also has in-app destinations, such as an Instant Experience or a chat, or when the format includes extra links. The general idea behind all three is covered in CTR.

How to calculate it

Divide outbound clicks by impressions and multiply by 100. Ads Manager has a ready-made column under Clicks, called CTR (outbound click-through rate), and a unique version that counts people rather than clicks. The CTR calculator does the sum for any pair of numbers.

Worked example

Example: two ads at the same ₹200 CPM.

Ad A Ad B
Impressions 50,000 50,000
Outbound clicks 450 900
Outbound CTR 0.9% 1.8%
Cost per outbound click ₹22.20 ₹11.10

Doubling outbound CTR halves the cost per visit at the same CPM. That's why it is one of the first numbers to check when cost per purchase rises.

What is a good outbound CTR?

It varies widely by category, placement, country and audience temperature. Retargeting usually beats cold audiences, and Reels placements can behave differently from Feed. Benchmarks borrowed from other brands are a weak guide. Compare ads with each other inside your own account, over the same dates and placements.

How to improve it

  1. Win the first second. A strong hook rate gives the rest of the ad a chance.
  2. Make the offer and the product obvious, so the right people click.
  3. Match the call-to-action button to the next step.
  4. Rotate creative before ad fatigue sets in, since outbound CTR usually falls as frequency climbs.

Frequently asked questions

What is outbound CTR on Facebook ads?

Outbound CTR is the percentage of impressions that produced an outbound click, meaning a click that took someone off Facebook or Instagram to your website or app. It is the CTR that tracks closest to real store traffic.

What is the difference between link CTR and outbound CTR?

Link CTR counts clicks on any link in the ad, including destinations inside Meta such as an Instant Experience or a chat. Outbound CTR only counts clicks that leave Meta's apps. For an ad that links straight to your site the two are usually close.

What is a good outbound CTR?

There's no single good figure, because it depends on category, placement, country and whether the audience is cold or warm. Compare ads inside your own account over the same dates, and judge outbound CTR alongside conversion rate rather than on its own.

Why is my outbound CTR high but sales are low?

The ad is getting clicks but the visit isn't converting. Common causes are a mismatch between the ad and the landing page, a slow or broken page, a price surprise, or an ad that attracts curious clickers rather than buyers. Check landing page views and the page itself.
