Everything About Facebook Attribution Window [2025]

Facebook attribution window is crucial for every Facebook ads user because it grants deep insights into campaigns and ads. Without it, you will easily be lost. 

So, we are here to not let that happen. Dive with us into all you need to know about Facebook ads attribution window.

Understand Facebook Attribution

What Is Facebook Attribution Window?

As in marketing, attribution represents the analysis of customer touch points before a specific action aligned with your target is taken. 

A quick example: we click on your ad, browse the website, leave, click on another ad of yours after a few days, browse the website and then buy a product. Now, the first ad or the second ad will get a credit based on the attribution model that you chose. 

And yeah, Facebook attribution (or Meta Attribution) works just like that. Whenever an ad leads to conversion, it gets attributed by Facebook. 

From this, Facebook or Meta attribution window shows the time between views, clicks from the customers and their actions on the website. Of course, you are allowed to change the window’s Facebook ads attribution settings.

Now, this conversion attribution thing sounds pretty similar to each other, right? We mean like it is all related to tracking conversions. But, Facebook actually separated them into attribution window and conversion window (before that fateful day).

Oh yes, and remember that “fateful day” because we will talk about it really soon. 

Now, we have known the answer for the question: what is Facebook attribution. Let's see why Facebook ads users are crazy about it.

Why Is Meta Ads Attribution Window Important?

Measure!

With proper measurement, you will better understand your campaigns and ultimately generate more ROI (return on investments) from them. 

In the current times, people rarely purchase, subscribe, etc. after the first impression. Usually, it will take a couple of times for them to finally do something with your business. And how do you even know which ad leads to what? 

So, the Facebook attribution window draws a big picture for you to look at rather than only separate indicators like reach, click-throughs, etc. A person sees your ad, gets interested but he or she is busy doing something and that person then comes back to see your website later and even makes purchases. The ad attributed sales, but without the Facebook attribution window, you will only see that ad as ineffective. 

Now, it is easily seen that your marketing efforts really pay off. As such, with data, Facebook ads become a playground for you.

Changes in Facebook Attribution

Here we come, that fateful day we just mentioned. The 25th August, 2021. 

Thanks to iOS 14 and Apple’s App Tracking Transparency (ATT) policy, the much-loved Facebook attribution window was retired. 

Facebook ads users were definitely shocked after the announcement from Facebook because a handy tool will be only a good memory. 

But yeah, Meta does not let us down (at least in this case). The new Facebook attribution settings were immediately introduced with some notable adjustments. 

The first change is the merge of both attribution window and conversion window into a thing called Facebook attribution settings. 

Attribution setting in Facebook ads now includes only 1-day click, 7-day click, 1-day click 1-day view and 7 day click 1 day view attribution (default). 

As a result, a shorter time gap surely either makes important data missing or reports fales numbers. What if the purchase or sales takes place 8 days after clicking on an ad? Well, Facebook will not target that type of person although he or she really bought something.

Here is another case. We click on your ad A, see the website, like a product but then leave because of some reasons and completely forget about buying the product. After 10 days, destiny guides us to your ad B, we remember about your product and we buy it immediately. 

Now, ad A will not get the credit which it deserves like before the Facebook attribution window changes. That will give Facebook a completely misleading view of that ad and deliver might go wrong. 

The ads optimization of Facebook gets hit really hard this time.

That being said, the 28-day click still made the comeback, but only under the form of reporting. It was brought back to life by Facebook at the end of 2022. Why? Well, nobody knows.

Know what is more scary? You cannot optimize vital numbers like ROAS or ROI because a certain amount of potential customers might be skipped by Facebook optimization. 

Feeling worried? No need to be so, because we have prepared some recommendations for you below. So, keep reading with us. 

But yeah, regardless of those things, the Facebook attribution window is still worth using even though the data reporting abilities have diminished a bit. 

Now, come with us and learn how to set up the Facebook attribution window.
