Articles and / or literature about the correct placement of contextual advertising

Question

contextual advertising

Good afternoon. Actually the question is in the title. I understand that "Google to the rescue", but I have already spent quite a lot of time searching. I stumble either on an advertisement of some resource for promotion, or on information that is morally obsolete. Interested in how to correctly calculate the company's budget and how to correctly and economically place ads in Google and Yandex. I placed myself and calculated on test days. Now they have given a task on a larger scale, which causes a big headache.

Answer 1

In any case, no matter how much you read, experience will not replace anything. Until you fill the bumps and drain the money, you won’t achieve mastery.
