I tried to promote myself for a long time because I thought that it was absolutely unprofitable to turn to ads specialists. I thought that they would keep my account, suggest possible types of posts that I would do and something else, but I was wrong. In fact,
Google Advertising Manager not only helps promote my content and puts ads on different social networks, in the browser, and in Google, but also selects interested users. That is, this type of service is very effective and really works! It is a pity that I did not guess earlier - we would have saved a lot of time and money...
