Working with Miralinks and what are the English equivalents?

Question

Search Engine Optimization

Good afternoon. I recently came across an article where a person praised the Miralinks exchange, said that it was more efficient than others. I want to start buying links, I have already written an article with three links. The following questions arose:
1) Share if you know if there are analogues of the exchange for the English-speaking segment. So that cheap eternal links, and so that I write the article myself, otherwise it’s expensive to order.
2) Does it make sense to order link strengthening? It costs 65 rubles, and bots use it for three months. Does it give any effect other than purely temporary?
3) What do you think about very cheap offers? Let's say with TIC 10 and MR 70 you can find from 70 to 100 rubles. But with smaller parameters, there are also cheaper options from 20 to 50 rubles. Is it always stupidity, or can such links be useful?
4) How many of them to leave on a small site with low attendance six months old?
5) And a question about the type of links. On the stock exchange they are anchor, I read they need to be diluted. What resources can be used?

Answer 1

2) Very doubtful. I tried this way and that, but unfortunately I missed tracking the result ... According to the information I had earlier, it's not worth it.
3) Links are useful if there are clicks on them. For Yandex, this is important. Look at traffic, the number of phrases in organic content, and the anchor list of the donor. Today he may be doing well, but tomorrow the ACS ...
Actually, it is recommended to look at the price only at the end, when looking for donors.
4) If this is a future linkopomoyka, I think it's not worth it. Evaluate the purpose of creating a resource.
