I work as a freelancer that is, I work remotely. I understand the various orders to promote any sites as well as web sites or telegram channels. I use SEO marketing that is selecting the right sites to promote quality links. At the moment I use the system SEMrush. Allows you to determine the visibility of the resource on the keywords in Google. The service is convenient for building reports and conducting audits of the site. However, SEMrush has one big minus: it does not work on Yandex. Yandex is very often used . And this program is free and gives poor quality site audit . And for this I am looking for a suitable paid quality tool .
