AD PLACEMENTS FROM SCRATCH
When we set up advertising on Facebook and Instagram via the Ads Manager, we go through 3 stages of settings:

Campaign, or the choice of the target,
Ad Set,
Creation.
At the ad set level, one of the key settings is the selection of so-called placements:

Placements is the section where we decide where our ad will appear.

There are a number of options available here:

We decide whether the ad will be visible on Facebook, Instagram, Audience Network or mexico rcs data Messenger. That is, we determine which platforms will be taken into account by the advertising algorithm, which will choose where the ad should be displayed;
We choose the device on which we will be visible – on mobile phones, only on computers or tablets, or maybe in both places at the same time? Or only on selected iPhone models, for example the top-of-the-range ones.
So there are many possibilities. The ad manager gives us the choice of whether we want to use automatic placements or configure them manually. And here the question arises, should we change anything?




Leave the automatic placements. There will be very few situations or reasons why you should actually change anything about them.

Why?

To answer this question, let's consider why users make changes to settings in the first place:

1) They are trying to transfer certain practices from Google directly to Facebook.
If you are involved in advertising on Google, you probably know that one of the methods of optimization is to divide the campaign by device. That is, if we want to have more control over the budget and who and in what circumstances we reach, we set up a separate campaign for mobile devices and a separate one for "stationary" devices (for example, a laptop or computer).
