In effect, VigLink works as the middleman between a publisher (blogger) and merchants by scanning the publisher’s content and automatically creating links to publishers that are chosen “in real time” based on their payout/conversation rates. This makes VigLink a very hands-off affiliate program for publishers who prefer to focus on content instead of managing their affiliate links.
This site is an example of what many sites are doing these days. They are “niched down” into brackets of certain products, and creating an online multimedia experience in the form of an online magazine style site. There's lots of large pictures, some videos, and it looks like a true media property. Chances are that you'd need to hire a designer to get a similar look and feel for your own website if you were to attempt it. From a revenue perspective, this site is more than likely doing more than six figures in total revenue if I had to take a guess, just based on their organic traffic numbers.
I'd say the content on this site is a little less “in-depth” when comparing it to LearnHowToBecome.org, but the content is still very good (hence the reason a 600 word article is ranking well for a high volume keyword). While it's difficult to judge based on traffic estimates, I would make a guess that LawyerEdu.org is making over $10k per month based on lead sales. If you remember, CPA/Lead sale programs can yield up to $50 or more per lead, and some professions and/or schools pay even more for them. Overall this site doesn't have a ton of content, but the content it does have is super informative and hyper focused on one line of work. It also has an excellent link profile, which is another reason it's ranking well.
Which affiliate marketing program or network you sign up for, whether as a merchant or an affiliate, will have a huge impact on the success of your sales. Some programs are niche and cater largely to a certain industry, such as technology/software or retail sales. Some programs don’t pay as well as others and will, consequently, result in lower income for affiliates over time. Some programs take a larger cut of profit than others, leaving affiliates with less income. Some networks just don’t have the same features as others and can leave merchants and affiliates with fewer resources.
An affiliate agreement is when a company or an individual agrees to pay you for successful referrals. For example, Amazon has a massive affiliates program where they pay you a percentage of the sales you generate using their affiliate links. Affiliate marketing is everywhere these days. In fact, we’re able to offer our own Blogging Mentorship Program for free because Bluehost sends us money for every customer we refer.
