How to track traffic in unity?

Question

Facebook

Hello.
There was such a question. Let's say I ordered an ad for my game from FaceBook. Let's say I pay money only for the installation.
Can I somehow in Unity, using the same FaceBook SDK or Unity Analytics, determine from where the installation was, from switching from advertising, or the user simply installed it by finding it in a search in any Market (Google, Apple)

Answer 1

Do full integration.
Facebook SDK is built into the game. and when initializing it, something like “I installed such and such an application”
is sent on Facebook (in fact, an ID and access to statistics and an advertising company in your case)
and now. By substituting ads, Facebook remembers various user IDs. and if he looked at the advertisement and then, let's say, put the game in during the day, it is considered an install.
but specifically on facebook, you need to find out if they offer advertising on instals. maybe the conversion is already your problem, they probably only sell views or clicks.
because the attractiveness of the advertising banner, the description in the store, etc. is, in fact, not their concern. and showing something for the "settings" that they do not want to install is not profitable for them.
they sell a billboard, not "we will bring you players"
