what they mean is a website or blog that you will use to pre-sell to your prospects before sending them to the sales page.you can just setup a wordpress blog.it is very easy and just take a few minutes to install.

go buy a domain name 1st for your blog at godaddy or name cheap.then get hosting from hostgator.take the unlimited domain name hosting package so that you could use same hosting package for several different websites.you can search on the internet for hostgator coupon codes.

then install wordpress blog and add some content like about yourself.once you setup the blog apply as an affiliate to the program that you wanted and provide them the url of your domain name.once you are approve go write a blog post about the product review or make a video review.

then start driving traffic during the pre-launch of the product.since it is 4 weeks away,you have sufficient time to prepare yourself.hope that helps you.
