How trustworthy are Alexa statistics?

Question

Typography

Guys and girls,
can you give me your opinion on the credibility of the statistics collected by Alexa.com?
How can you trust her?
Otherwise, it’s a convenient site, but it’s confusing that I know that there are a lot of visitors to another site (whose statistics are interesting) from a certain country, but Alexa seems to indicate the leadership of another country among visit statistics.

Answer 1

For Russian-language sites, alexa is not very relevant, I have seen how the rank of similar sites fluctuates a lot or a site with less traffic has a higher rank. There are also jambs on search queries, for example, it shows English-language queries in the top on one of my sites - in principle, they cannot be there and GA confirms this.

Answer 2

Always divided, at least by 2, all indicators from resources such as Alexa. So at least it becomes closer to reality.
