This is one of the most popular ways to make money on the Internet today, everyone probably starts with it, because it does not require any investments, you can get your first money in just 30 minutes, but the disadvantages of this method include the fact that on he will not be able to earn any serious money (even with a great desire).
The essence of the method is as follows, you just need to perform some actions on certain sites or social networks.
For instance:
Click on an ad;
Register;
Take a survey;
Write a comment;
Like;
Make a repost;
Join a group or community;
Evaluate or compare something;
And other simple tasks;
Almost all of this refers to the so-called cheating.
Note!
If you yourself are going to promote your site or group on a social network, then I do not advise you to use cheating to gain subscribers or likes, since now you yourself understand that all those people who, for example, joined your group on a social network - this is absolutely not the target audience, there will be no benefit from it, only the very fact of the presence of participants, and if this is abused, the group can be completely blocked.
In this direction, there are many different services, such as:
SeoSprint and WMmail are some of the largest and most reliable services on which you can perform various tasks, or act as an advertiser yourself and create tasks;
VKTarget - earnings on likes, reposts and subscriptions in social networks;
Yandex.Toloka - earnings on simple tasks, for example, evaluate a site or compare two pages of a site.
