The basis of it is that you have your own blog set on a specific niche, the advertiser has a product that matches the niche of your blog and they then pay you (varying amounts) to post blogs to your network of visitors about their product.
This is good for you because it earns you money, but also good for the advertiser because they get their product promoted easily, gaining a huge amount of traffic from your blog.
To do this you must:
- Have your own blog set up. (Set up a blog here)
- Understand how to use the Internet and blogging tools
- Be able to write concisively on specific topics
- Give appropriate reviews and information on products
- Have a little spare time!
