need help in internet marketing without capital

My first recommendation will be to only use the black colors when typing on this forum.

Ok, here is what happens.

I'm not sure where you live, but the requirements to join affiliate programs may not be suited for you if you are in some countries.

Most affiliate programs are 100% free to join. So you join and give them your necessary information.

The program will give you a special link. When you make a web page somewhere on the web, you will put your link on the page. When a customer clicks on your link, they are typically directed to a main sales page for the company who you are an affiliate for. If the customer makes a purchase, the company is able to see that the purchase came from your special link which is your referral.

Typically there is some kind of back office or somewhere you can log in to to see if you have made sales.

When do you get paid? That information will be presented to you when you join the affiliate program somewhere in the terms of service.

Hope that gives you a bit of a start in understanding the process.

Websites that allows to sell product for them that's better home business.
