Affiliate Web Site

can any one tell me if these affiliate web sites work and how to start one?
and is it really worth it and how much do they cost to set up
They work if you work it of course, Ive been an affiliate marketer since 1999, my first commission was $450 us , since i live in Australia that double to $900, it was for windows casino, I basically just threw up links anywhere I could put them, sent out bulk emails, purchased search engine blasters, and it paid off, although it was a lot easier back then due to low competition, and also easier to get into the search engines. Nowadays there is a ton of competition out there, and search engines are a lot smarter, they are attracted to high quality content. Although a lot of affiliate marketers really have no idea how to go about it, they are doing things the way I use to 10 years ago, throwing up pointless adds, people don’t want adds they want either a good honest review on a product, or a good informative website about the subject.
Therefore I started creating websites that helped people such as a good review site about a product or service, or a keyword content rich site that presold the buyer before sending them to my affilaite merchant.
You see affiliate marketing is a team effort, your job is to pre-sell the visitors on your site, your merchant does the selling . I see a lot of affiliate marketers just copy and paste what is already on the merchants website, so there visitor reads what is said then clicks the link and reads it again, Very unlikely they will buy. But if they read a good article or page on your website about the experiences you have had with the product or something about the subject that leads to a recommendation it is a lot more effective.
So yes they definitely do work, down below are a couple of links where you can download a free affiliate training course that will teach you exactly the right way to go about affiliate marketing, also the company that trained me, check them out when you can.
