Sites like Cookening, EatWith, and MealSharing are to restaurants what Airbnb is to hotels. Sign up as a host to earn dough by cooking and serving meals to guests in your home. It's up to you what you want to cook and how many people you can accommodate. Cooks are paid directly through the site, so no cash ever changes hands. The earning potential for becoming a cooking host is $50-$100 per meal.
Betfair Affiliates is the affiliate marketing program for the well known Betfair betting website. Betfair’s primary market is sports betting. It’s actually a betting exchange, so it allows gamblers to place lay bets too – in other words, bets that bank on the opposite outcome. Betfair also offers in-play betting that allows users to lock in profits before the match ends. They also have great offers for the new customers to Betfair Casino.
The phrase, "Affiliates are an extended sales force for your business", which is often used to explain affiliate marketing, is not completely accurate. The primary difference between the two is that affiliate marketers provide little if any influence on a possible prospect in the conversion process once that prospect is directed to the advertiser's website. The sales team of the advertiser, however, does have the control and influence up to the point where the prospect either a) signs the contract, or b) completes the purchase.
I’d stick with Amazon if I were you. All of my Amazon sites only have Amazon affiliate links. If you use Google Adsense display ads on your site, you’re literally taking people away from your site for the sake of just a few cents with these type of ads. If you direct them just to Amazon, then you have a greater chance of earning more money from that click.
