I would have one partner create a separate page/contact form specifically for the advertiser – so only people who see that contact form are people who were referred to by the advertiser. The advertiser would use that page as their outbound link. I know you can track outbound clicks in Google Analytics events and Contact Form conversions (usually through most contact form plugins) but that is the best way I think. Never done it, but this is how I see most affiliate programs like that work.
The internet offers boundless possibilities for earning a living online. Upwork and Freelancers Union found that 35% of the American workforce was doing some type of freelance work in 2016, and 73% said technology made it easier to find that work. One of the ways to harness the internet as an income source is pursuing affiliate marketing. It’s intended as a way to generate passive income, but does it really work? Let’s consider. 
Affiliate Marketplaces – ShareASale and ClickBank have thousands of merchants to choose from. It’s nice to login to 1 place and check the performance of multiple affiliates without going to each individual portal on each website. Many programs aren’t part of a marketplace though. I’m a big fan of ShareASale – there are so many companies and industries you can choose from.

3. Termination. Amazon may suspend or terminate Influencer’s participation in the Amazon Influencer Program, and Influencer may terminate such participation, in each case immediately by notice provided in accordance with the termination provisions of the Agreement. The rights set forth in Section 2 of this Influencer Program Policy will survive the termination of Influencer’s participation in the Amazon Influencer Program; provided that, we will use commercially reasonable efforts to remove any Influencer Marks from the Influencer Page following termination.

How established is your site/blog/social media following?  Do you already have an audience of 1 million or are you just getting started?  Early on in your affiliate marketing journey you will probably want to have multiple options to make sure you can cover a broad field. You might want to become an Amazon Associate as well as joining one of the networks so you will have a product link to drop into any posts you do.  An easy place to start is to promote the services you are using if you are enjoying their product - web hosting or email management systems like Aweber.
Sellers are responsible for claims they make about their products and services. Third parties - such as advertising agencies or website designers and catalog marketers - also may be liable for making or disseminating deceptive representations if they participate in the preparation or distribution of the advertising, or know about the deceptive claims.
I’m actually glad you brought this up because I get this a lot from my readers. People often think that I only recommend Wealthy Affiliate but that’s not true at all. If you look at the menu tab that says “Recommended” you’ll see that there are few programs that I recommend. Niche Tycoon, AffiliateU and Laptop Lifestyle Academy are the other three that I point out. So these are my 4 favorite programs that I really like for people who want to make money online but that’s not to say they are the only good ones. There are plenty of good ones bu these 4 are my personal favorites. I often say that Wealthy Affiliate is my favorite though because it’s geared for beginners who want to make money online. If you have no previous experience making money online then I think Wealthy Affiliate is the best choice.

Sometimes, individual entrepreneurs with great products are worth a look, although you should check them out first and do some research. Entrepreneurs or companies may run their own affiliate program and you can apply directly to them to promote their products and services. Finally, Amazon is always an option as you can be an affiliate for just about any type of physical product on their network.
The training is in the form of videos that will guide you through the steps of building an online business and how to become a successful affiliate marketer. There is also a live community where you can ask questions, interact with other members etc. Basically, their training is all about promoting SAN and recruiting new members. There are different kinds of memberships, upsells, and courses you will be “encouraged” to buy.
It’s important to know where your traffic is coming from and the demographics of your audience. This will allow you to customize your messaging so that you can provide the best affiliate product recommendations. You shouldn’t just focus on the vertical you’re in, but on the traffic sources and audience that’s visiting your site. Traffic sources may include organic, paid, social media, referral, display, email, or direct traffic. You can view traffic source data in Google Analytics to view things such as time on page, bounce rate, geo location, age, gender, time of day, devices (mobile vs. desktop), and more so that you can focus your effort on the highest converting traffic. This analytics data is crucial to making informed decisions, increasing your conversion rates, and making more affiliate sales. 
“It took me about six months to make my first affiliate sale, and my first affiliate sale was worth about $35,” Miki says. This blogger went on to say, “I didn’t make my first dollar until I decided to invest in the “Making Sense of Affiliate Marketing” course. Taking an affiliate marketing course was the best decision I ever made because I had no idea how much money I was leaving on the table. This course taught me the exact strategies to make money with affiliate marketing.”
I must say the professionalism is as much as expected from Omar and Michael (outstanding!). Omar and Michael are my go to guys when it comes to cast iron affiliate marketing campaign strategies, there is literally nothing these guys don’t know about the affiliate marketing business.

Sit down with a coffee, grab a pen and pad and allow these two guys to set you on track for a future of income success! Seriously, your idea of earning commissions is the tip of the iceberg to what these guys can show you. In short.. It’s awesome!
