Link Clicks vs Reach

In short: Link clicks counts click events aimed at a destination - your site, an Instant Experience, an app store listing, a Messenger thread - while reach counts the unique people who saw the ad at all, regardless of whether they clicked anything. Because link clicks includes destinations that never leave Meta, it can run higher than the traffic your site actually receives, even as it looks traffic-shaped. Reach never claims to measure response, only exposure. Use reach to size the audience an ad was delivered to, and link clicks to see how much of that audience took any destination-aimed action, then check outbound clicks before assuming any of it left the platform.

Link Clicks

Meta's count of clicks on links leading to advertiser-specified destinations, including on-platform ones such as Instant Experiences, app stores, and Messenger threads.

Narrower than all clicks, wider than outbound clicks. It includes clicks that keep people inside Meta, which is why it can exceed outbound clicks on the same ad and badly overstate site traffic for canvas or lead-form creatives. The common misreading is treating it as sessions; landing page views run consistently lower because of drop-off and slow loads.

Reach

The number of unique people who saw an ad at least once during a specified period, deduplicated across all of its impressions.

Reach and impressions coincide only at a frequency of one. It is estimated and tied to accounts or devices rather than humans, so shared devices and duplicate accounts distort it. It also cannot be summed across date ranges or campaigns without counting the same people twice. The common misreading is adding weekly figures together to claim a monthly total.

Side by side.

The differences that actually change what happens in your account.

	Link Clicks	Reach
What counts as one event	A click toward any specified destination, including on-platform ones like Instant Experiences and lead forms.	Nothing is 'counted' as an event; it's a deduplicated headcount of unique viewers.
Whether it can include non-website destinations	Yes - app store links, Messenger threads, and on-platform canvas experiences all count.	Not applicable; reach doesn't track destinations at all.
What a repeat clicker does to the number	Adds to the total each time, unless you're looking at the unique variant.	Never adds again; the same person is only counted once in the period.
How it compares to real site traffic	Overstates it whenever on-platform destinations are part of the campaign - check outbound clicks for the closer figure.	Makes no claim about traffic at all; it's the exposure side, not the response side.
What a rising count with flat reach signals	The same audience clicking repeatedly, often visible near the top of a frequency curve.	Not applicable - reach staying flat is the baseline this comparison is read against.
Failure mode	Treating it as equivalent to landing page views; actual page views run lower due to drop-off and slow loads, and lower still if destinations included non-website links.	Summing it across separate campaigns or weeks and reporting inflated unique-audience totals.

What actually separates them.

Link clicks counts destination-aimed click events, some of which resolve inside Meta itself, while reach counts unique people with no reference to destinations at all.

A single person can generate multiple link clicks in a period through repeat visits or multiple ads, while that same person only ever counts once toward reach.

Link clicks is inflated by on-platform formats like Instant Experiences and lead forms in a way reach structurally cannot be, since reach only tracks who was served an impression.

Rising link clicks against a flat reach points to repeat action from the same people, typically late in a frequency curve; rising reach against flat link clicks points to audience growth without matching interest.

Link clicks divided by reach gives a rough 'percent of the audience that took some action' figure, which is a different and looser number than the platform's own impression-based click-through rate.

Which one should you use?

Use Link Clicks when

You want to know whether people are taking any destination-aimed action, including canvas, lead-form, or app-store flows, not just website visits.
You're comparing creative variants for pull toward the destination before deciding which one drove real traffic.
You need a number close to but not equal to landing page traffic, and you're prepared to cross-check it against outbound clicks.
You're auditing a campaign that mixes on-platform and off-platform destinations and need to see the combined total first.

Use Reach when

You need the baseline unique audience size the link clicks are being measured against.
You're managing frequency caps and want the deduplicated denominator.
You're sizing an audience before a campaign has generated any clicks yet.
You're checking saturation before deciding whether to expand targeting.

Common questions.

Why do I have more link clicks than outbound clicks?

Because link clicks includes destinations that stay inside Meta - Instant Experiences, lead forms, Messenger threads - while outbound clicks only counts clicks that actually leave the platform. The gap between the two tells you how much of your traffic-shaped number never reached your website.

Can I use link clicks divided by reach as a CTR?

You can compute it, but it isn't the platform's click-through rate, which divides by impressions, not reach. What you'd get is closer to 'percent of the unique audience that took some destination-aimed action,' a useful but different number - keep it labeled as such so it isn't confused with CTR.

Is a growing gap between link clicks and reach a problem?

Not by itself. It usually means the same audience is clicking more than once as frequency builds, which is normal on a running campaign. Watch it alongside outbound clicks and conversion data before deciding it's a fatigue signal.

Should I trust link clicks as my website traffic number?

No. Use outbound clicks as the closer proxy, and reconcile even that against your site analytics, since on-platform destinations, blocked tracking, and slow-loading pages all create gaps between link clicks and actual sessions.

Or stop choosing between them.
