Is it possible to integrate an information portal with an online store?

Question

Electronic commerce

Good afternoon, dear experts.
We are developing a new version of the information portal. We have
launched our own line of sports supplements. We are planning an online store.
Question: if sales of products will be carried out directly on the project website, can this alienate new users? Or it would be more rational to create a separate domain with a separate online store.
Advantages of the first solution:
- ready-made subscription base (registered participants)
- two in one
Cons:
- decrease in audience loyalty due to "sales directly on the resource".
Thank you! If there are additional materials that can be studied on this issue, I will be very glad. I did not find a solution to this situation on my own.

Answer 1

I advise you to do the opposite: integrate an information portal into your online store...
