Social networks provide a lot of opportunities to ensure an increase in the visibility of the site. You can attract visitors from social networks in various ways. For example, a very effective option is the creation in social networks of thematic groups that "revolve" around your web resource. It is enough to attract people from the target audience here, and they will attract more and more visitors to the group as a magnet. Successful promotion of a group and a site in a social network can be compared with a geometric progression - one person leads two new visitors, those in turn also attract n number of users, as a result attendance grows like a snowball. However, in order to increase the traffic to the site with the help of groups and communities in social networks, you need to be able to correctly determine the membership of users to your target audience.
