Do any affiliate program in this world of internet works and does they pays really if yes they who are they and why they are paying us for just completing offers and just by sign up for them. if there really affiliate program which is legit can anyone say something about them.
First, your idea about affiliate program is incorrect. If you think scams like "get paid for reading emails" or "get paid for taking survey" are affiliate programs, they are not. In real affiliate programs, you(an affiliate) refer a customer to buy goods/services and the merchant pays a percentage of his profit to the affiliate. That is a win-win situation. To make money from affiliate program, you should have quality traffic which is interested in buying services / products you refer. Affiliate program in that way is a way to monitize your site, just like pay per click ads etc. If you buy traffic and try to monitize it, you will most probably be in loss. On the other hand if you have good traffic on your site / blog, affiliate programs offer you a good opportunity, provided your niche and traffic are good - that buy online. Bottom line, success of affiliate program is related to having a successful website, not signing up with xyz and hoping to get rich.
Yes Affiliate network Pays for sure. and like alemcherry told this is win win situation because the merchant whose product we promote gets his profit from the sales and he share the % of profit . So You (affiliate) Gets % the merchant gets his profit by the customer you refer and the customer takes the product what he purchased.
