Before you get eager about marketing on the Internet with mini-sites, I think you should be clear about the types of mini-sites that you can build. These mini-sites are different, depending on the objective of the site and also the structure.
In general, I consider mini-site as a website that is easy and simple in structure and very narrow (probably deep) in topic.
1 – Sales Letter Mini-Site
This is normally a simple 1-page website (not including download page, support page, etc). It contains a direct response sales copy convincing the website visitors to buy a product.
I am sure you’ve seen a lot of these. You can go to any websites from the ClickBank Marketplace and 99% of them are Sales Letter Mini Sites.
Whatever you do online, ultimately you want to have your own product. You make more money that way. And when you do, this is the type of website you want to have.
