When you run Facebook ads and look at the results in Facebook Ads Manager, you're looking at Facebook's version of what happened. When you check Google Ads, same story — Google's version.
The problem? They have every incentive to make themselves look good. And with iOS privacy updates gutting their tracking ability, even their best-effort numbers are often way off.
You're making budget decisions based on data you don't own, from platforms that benefit when you spend more.
The difference between first-party and third-party data
Third-party data is collected by someone else and shared with you. Facebook's pixel, Google's conversion tracking — these run on someone else's infrastructure. You see the output, but you don't control how it's collected, what gets included, or what gets filtered out.
First-party data is information you collect yourself, on your own infrastructure. It belongs to you, it's not subject to another platform's algorithmic choices, and nobody can take it away by changing their privacy policy.
The simplest and most immediate way to start building first-party data is through link tracking.
Why link tracking is the foundation
Every link you share is an opportunity to collect your own data. When you paste a raw link into a social post, you hand that opportunity to whatever analytics platform happens to fire on the page. When you route it through your own tracked link, you log the click on your own server — before the user ever hits your site.
You get: the exact timestamp, the referring platform, the country, the device type. All of it, without relying on Facebook to tell you about your own campaign performance.
Over time, you build a dataset that reflects reality, not a platform's preferred version of it. And when Facebook's numbers and your numbers start to disagree — which they will — yours are the ones to trust.
