I find it interesting to post such a question on something as public as Yahoo Answers: I wonder how many people will post dozens of affiliate links to GRQ programs etc!

Personally, my experience of affiliate marketing is making a little income through Amazon Associates (laptops and books) and a Wholesale Directory. In every case, the pages with the links on weren’t especially promoting the product in question. You could call this ‘passive affiliate marketing’. I did have a lot of traffic though until I sold up.

My current website, I’m focusing a bit more on active promotion where I feature and talk about the product in question. That way, I can shift higher-ticket items – some of my favourite affiliate programs I’ve featured here: http://www.how-to-build-a-website.co.uk/free-to-join-affiliate-programs.html

I know you’re not going to like the paid material, but Affilorama offers a free level of membership which is quite good. They do promote their premium level of membership ($67 monthly!) and try and entice you in with one-time offers etc. but have a look at the free program. http://www.affilorama.com/

I’ve also got rights to distribute this eBook: http://www.how-to-build-a-website.co.uk/support-files/affiliate-masters-course.pdf – It’s 152 pages long, and it helped me focus on the affiliate marketing strategy for my current site.

1) Are there any legitimate affiliate programs ?

Yes and it would be best to create one from your website and to get your visitors to use your affiliate service and sell the product you offer. Simply just taking others products and selling them online within a squeeze page does not simply work as its all hyped to be.

Search engines will crack down on these pages which don’t bring any value to the "conversation" on the internet.
(Remember valuable content will bring traffic)

2) how can I be sure I don’t get cheated ?

The terms of service may have to be read carefully from affiliate sites in order to determine if the purchase goes through accounts on their website instead of directly being paid out by the author of the product. (its like elance they are the middle man).

3) where can I create a simple sales page ?

If you don’t know basic HTML there could be simple programs which can generate these pages, but it’s not advisable to use any sort of automated program to create them as major search engines may have filters to filter out certain tags/credits mentioned on the page, thus pulling your squeeze page from their index.

4) how to gain genuine unique vistors to your page (PPC any good?)

Valuable content is always going to be king. Having content which is being searched for will rake in visitors. You need to research white hat seo techniques. Just simply having a page online and submitting it to a few search engines doesn’t mean you will get tens or even hundreds of visitors a day.
