Outbrain is not necessarily the network of choice, it was just an example. As for tracking the ROI usually you'll want to track campaigns in Google analytics and track clicks on affiliate links as event and average value/email or you'll want to duplicate the post and run paid traffic to the duplicate so you know exactly what the conversions are as you can put them in separate email lists etc too.
What’s the catch? None, really. Cash back apps act as affiliates for many online merchants, which means that whenever you make a purchase through one of the apps, they get a small commission — but then, they give you a portion of that commission as “cash back”. For example, if I buy a pair of Nike shoes through the Ebates app (or website) and spend $75, Ebates may get a $10 commission but then they’ll pass $7 back to me. It’s basically a way to get sale prices on stuff that isn’t on sale!
There are loads of resources for making money online as an affiliate. You could source products from ClickBank, Commission Junction, Rakuten Marketing, Share-a-Sale, Impact Radius and many others. Plus, many of the larger companies have their own affiliate programs as well. Do your due diligence and find the right company with a relevant product or service to your audience that you can sell as an affiliate.
Equally, you can charge businesses to ‘claim’ their listing, a method used by many large directory sites like Google Business and Yelp. This involves companies paying to upgrade their listing and adding information such as their web address, social media links, images, and more. Other revenue streams include charging for ad space, adding affiliate links and even charging for services and products on your directory site.
Blogger, which you can set up for free in less than five minutes, automates Google AdSense so that you can make money with your blog by displaying ads and getting paid when people click on the ads. To make more money, set up an affiliate program (see below) for books, music, etc., and insert your affiliate links whenever you refer to those items. A good strategy to set you on the path to success is selecting a unique topic, writing intelligent copy, and telling all your friends. You're off to a good start with building a targeted audience.
Use your personal words & experience with the product. Your own content, or photos & videos of yourself using the product are always the most effective. For example, many affiliate programs provide swipe copy to their affiliates which is pre-written emails, post material or social media posts. These can be helpful as a guide, but they often scream swipe copy, aren’t written in your voice (the one your readers know!) and if a lot of affiliates are using it, are overdone.
Tremendeous free teaching, that helps clear the smoke on what it takes to get an online business going. BUT, you concentrated on click bank and said nothing about getting my web site going and all the necessary details. I always thought the web site as a business sign telling people that xyz is open for business, check it out! Otherwise, people would walk and not even knowing that your biz is open. True?
