There are not so many proven and really paid ways to make money on the Internet linearly (in the old way). This is, first of all, work on manual uniqueness of the text - rewriting.
In general, people who make money on the Internet by performing various work for specific customers are called freelancers (translated from English as "free artist").
Such a performer starts work without concluding a formal contract with the employer, and performs a certain list of jobs.
The advantages of working as a freelancer are that he can work simultaneously for several customers, earning more money and minimizing the risks associated with the fact that one of the clients suddenly abandons the services of a freelancer or cannot pay. All the same, there will be other customers.
It is worth noting that there are also disadvantages to such free work:
This is the need to search for proven customers who will not leave and pay for the agreed work, which is one of the most important problems.
The second disadvantage is that the job seeker must have certain skills that are in demand in the market. These can be skills in rewriting, copywriting, programming, website design, knowledge of foreign languages, then a freelancer will be able to offer text translation services.
And, finally, freelancing is, as you already understood, linear earnings, that is, you will have to look for clients constantly until you gain a positive reputation and a list of regular customers.
One of the most important elements of the success of a beginner freelancer is having proven customers.
Based on this, you need to register on the freelance exchange, where you can find potential customers and there is a great chance of getting a job.
