When it comes to selling online, one thing is certain: a small focused website that features just one lead product will far outsell a big website that features lots of products and links.
By focusing on just one product, you avoid distracting your visitors or forcing them to make decisions. That way, they'll take the time to study your product and the chances of making a sale are vastly increased.
I can see the evidence for this in my own business. While the main company website (BizzyDays.com) continues to bring in a steady stream of sales, it's actually the individual websites for each of the ebooks that are responsible for the lion's share of orders.
The problem, however, with having one website for every single ebook is that it adds a lot of extra overheads. In general you're looking at minimum $100 for any kind of webhosting and somewhere between $8 and $35 for a domain name.
