Traffic is the main component of any online earnings. I have read many methods on BHW but everywhere it is suggested to drive traffic from social networks. But there are other sites from which you can get traffic. I will talk about the method that I worked on a year ago.
I have used the forums.
Why are they good? All forums have a messaging system.
There are also disadvantages: work with forums must be automated due to the large number of users, and it is impossible to write to each user manually.
Another difficulty is that each forum has different restrictions (limits on the number of messages per day, the inability to send messages from new accounts, or too long a pause between sending). Because of this, I had to spend time checking the forums. I registered two accounts and checked if there are any restrictions on sending between messages, whether notifications come to the mail, whether the text is duplicated in the mail. If there were no restrictions, then using my own automatic script, I checked whether there were any restrictions on the number of messages sent per day. In case of their absence, I proceeded to register the required number of accounts.
The process of registering accounts can also be automated, which I sometimes did. But mostly I registered them manually. Usually I registered from 10 to 100 accounts. Their number depended on the restrictions that are on the forum. If there were no restrictions, then I registered the minimum number of accounts.
I also encountered such a problem that I could not register more than 3-5 accounts from one IP. My ISP provides a dynamic IP, so I just rebooted the router and continued to register. It took me about an hour to register 100 accounts manually.
For automation, I used one of the ready-made tools. I watched a few tutorials on YouTube, read a couple of articles about post / get requests, and then wrote my own script. Since all forums run on a specific CMS, I simply created a template for each popular CMS and for each forum I just made small changes that took 5-10 minutes.
For each forum, I used a unique tracker in the link. On average, from one forum I managed to attract 100-200 uniques and earn $10. Sometimes earnings could be less or absent altogether, and sometimes more. But I think I could get better results if I used spintax and a few different links, since most of the sent messages probably ended up in spam. Now I don't do it, but my path to CPA started with forums. I'll try to try this method again as soon as I have time, but now I'll improve my script a bit. I'll post the results in this thread.

If you have any questions I will be happy to answer them.
