How to analyze the sources of buyers?

Question

Conversion

We have different sources of customer traffic in the store. We want to have reports on the conversion of one or another source.

Is it possible to perform the following scheme, for example:

1. Add some identifier to the product url in the feed that we have loaded for Google products.

2. Next, the buyer follows the ad, surfs our site on Bitrix, and eventually reaches the goal - the successful ordering page ( https://site.ru/personal/order/?ORDER_ID= )

3. This moment is fixed. So the buyer made an order, initially getting to the site with Google goods.

It will be similar to other sources - contextual advertising, advertising platforms, etc. As a result, we would like to get a picture from which source how many orders there were. Is it possible to implement this somehow and tell me, please, a service where you can do this?
