What Is CTR in Facebook Ads? Link CTR vs CTR (All)

Click-through rate measures pull: out of all the times your ad appeared, how often did someone click? Meta reports several versions of it, and each one uses a different definition of a click. The link version counts only clicks on links to a destination you chose. If two reports of the same ad disagree, check first whether they use the same version.

How does Meta calculate CTR?

Meta calculates CTR (link click-through rate) as link clicks divided by impressions. Meta describes it as a common way to understand how ads drive traffic to websites and other destinations.

Example: 150 link clicks from 10,000 impressions is 150 ÷ 10,000 = 0.015, which is 1.5% when written as a percentage.

Which CTR metrics does Meta report?

Metric	Formula	Counts
CTR (link click-through rate)	Link clicks ÷ impressions	Clicks on links to chosen destinations, on or off Meta
CTR (all)	Clicks (all) ÷ impressions	Link clicks plus other clicks, such as Page name taps, reactions and media expands
Outbound CTR	Outbound clicks ÷ impressions	Clicks that take people off Meta technologies
Unique outbound CTR	Unique outbound clicks ÷ reach	Accounts rather than clicks; uses sampled data

Since every link click is also part of clicks (all), the “all” rate is never the smaller of the two for one ad.

Which CTR should you use for website traffic?

For a site or store, link CTR is the usual starting point, since Meta positions it as the traffic measure. Outbound CTR goes one step further. Meta says outbound clicks give a closer approximation of the traffic intended for your website or app, because link clicks also include taps into experiences inside Meta, such as Instant Experiences, lead forms and collections.

Can a high CTR still mean a weak ad?

Yes. Clicks are only one stage. Meta’s guide to ad relevance diagnostics names one pattern directly. When quality and conversion rate rankings are both below average while engagement rate ranking is average or higher, Meta reads the ad as “click-baity or controversial.” Meta’s advice is to adjust the ad so it represents the product or service more clearly.

Meta also says engagement-baiting, such as asking for likes or comments, does not improve an ad’s performance.

How does CTR relate to engagement rate ranking?

Engagement rate ranking compares your ad’s expected engagement rate with ads competing for the same audience. Meta defines that expected rate as the likelihood a person will click, react to, comment on, share or expand the ad. It is a broader notion than link CTR, and it is a prediction compared against competitors rather than a count of your own clicks.

To check whether a CTR change is real:

1. Confirm which CTR column your report shows: link, all or outbound.
2. Compare the same column over the same date range for each ad.
3. Review the result metrics before acting, since a higher CTR does not mean more sales.

FAQ

Why does CTR (all) read so far above link CTR?

CTR (all) adds every reaction, comment, share, profile tap and full-screen media expand to the link clicks before dividing by impressions. An ad that people like and comment on, but rarely click through, shows a high CTR (all) and a low link CTR.

Is CTR shown as a percentage?

Meta defines the metrics as a division: clicks divided by impressions. Multiplying that result by 100 gives the percentage most people quote. When you compare figures from exports or other tools, check that both use the same click type and the same scale.

Does a higher CTR lower my costs?

Not directly. With the same spend and impressions, more link clicks means a lower cost per link click by arithmetic. Whether cost per result improves depends on what happens after the click, which CTR does not measure.
