How to correctly set the frame in the Amazon affiliate program?

Question

Partnership programs

The initial goal of the affiliate program is to get the keys with which I can receive data about products.
I registered in the affiliate program, added my site there, a news site for more than 4 months, then I set their frame, the frame on my site looks like this

when I click on it, I go to the Amazon home page and in the address bar I see my tag

...co.uk/?tag=xxxxxxxxxxxx&linkCode=ez

but when I further click to select a category and a product, then there is no longer a tag in the address bar, how will this be considered?
Will a purchase from my tag count?
to get the keys one of the requirements 3 purchases with my tag, will it work or how is it right?
Of course, I can buy 3 products simply by adding my tag to the link and it will be counted, but most likely I will get a ban for this, I already did this, and I bought all 3 products from different accounts ...

Well, since the main thing for me is to get it keys for obtaining information about products (for the place of parsing) how else can I get the keys?
Tell me who knows...
