Answer 1

Answer 2

I think the term you are looking for is:

-> Advertising

The definition of advertising, from Oxford Languages, is "the activity or profession of producing advertisements for commercial products or services."

-> That is oh so helpful. The definition of advertisement is "a notice or announcement in a public medium promoting a product, service, or event or publicizing a job vacancy."

In other words, advertising means to let people know about your product or service, just as this question is asking for.
