Understand the difference between link clicks and outbound clicks in your metrics
This happens because Facebook and your analytics platform measure different things.
Facebook "Link Clicks" → Counts any click on your ad, including “See More,” profile clicks, reactions, comments, and accidental taps.
"Visitors" in your analytics → Only counts people who actually load your website.
How Do You Get More Accurate Numbers in Ads Manager?
Use “Outbound Clicks” instead of “Link Clicks.” Outbound Clicks represent people who actually clicked through to your site. This number is usually smaller but closer to your true traffic.
Check “Landing Page Views.”Landing Page Views are tracked when your pixel fires after the page fully loads. This is the most reliable metric for real visitors.
How to Check "Landing Page Views" in Facebook Ads Manager
Follow these steps to check landing page views as the metric in a campaign in Ads Manager:
Go to Ads Manager
Customize Your Columns - In your campaign or ad view, click Columns in the toolbar. Select Customize Columns.
Add the Metric - In the search bar, type Landing Page Views. Tick the box for Landing Page Views.
(Optional) Tick Link Clicks and Outbound Clicks as well so you can compare them side by side.
Click Apply to update your reporting table.
You will now see Landing Page Views as a column for each campaign, ad set, or ad.
Why There Is Still a Gap
Even after switching metrics, you will often see fewer visitors in your analytics than clicks reported by Facebook. Common reasons include:
Bots – Automated clicks inflate Facebook’s numbers.
Slow site speed – If your page takes 4 or more seconds to load, many people leave before your analytics can count them.
Multiple clicks – One person may click several times, but analytics only records one visitor.
iOS 14+ tracking limits – Apple devices block some tracking, creating a 10–20% gap by default. Loading both Pixel & CAPI side by side (as PixelFlow does by default) will resolve this.
Why It Matters
In summary, if you only look at Link Clicks as your result, you may think you are paying $5 per visitor. But if only 29 real humans make it to your site, your true cost per visitor is closer to $18.
