I have far better luck when I incorporate affiliate links into the body of a post. For example, if I’m writing about editing tips, I’ll mention that I use Grammarly and include a link like this one so that readers can try it out for themselves. However, you don’t want to be too spammy about this, which is why I think it helps to focus on products that you know and use and think will be of value to your readers.
You’re obviously not going to be targeting broad keywords like ‘travel’ and ‘traveling’. Actually, it doesn’t even matter if you’re going to be doing SEO for this particular site. What you really want to see is whether or not there is a demand for that particular type of traffic. As you scroll down, you want to look for cost-per-clicks that really jump out at you. For example, we have ‘student travel’, which has a suggested bid of $4.10 for one click. That might be a niche right there. Under the broadness of ‘traveling’, if you decided to do something about student travel, you know that there are advertisers paying $4 for one visitor. I’ve found in my experience that the higher this cost-per-click, the more affiliate offers and affiliate options you have. This is something to pay attention to. In general, the cost-per-click in the whole travel niche is quite low. For this reason alone and the fact that the Clickbank marketplace didn’t really have so many great offers that you could promote, you might want to go back to the beginning in Quantcast and look at another niche and follow the same process.
While the traffic estimates are lower than some of the other sites on this list, people in the baby gear niche are an important customer base because they definitely purchase products.  This is a big industry and I would guess that the conversion rate for this site is slightly higher than OutDoorGearLab.com.  Typically when someone researches a baby product, they are typically looking to buy that baby product.  If someone is researching a tent, they may just be looking around at different options that they can compare for their next camping trip – not necessarily to buy that tent.  Most of their traffic is organic, and continuing the trend of well ranked long form content, their top post is 8,800 words long (which is a beast of an article).  If I had to take a guess at revenue, it would probably be north of 30k per month for this site based on traffic.
Perrin has blogged about his site on the AuthorityHacker.com blog, and he's also openly discussed the sale of this site, which was sold at over $200K as the final sales price.  The site still does very well in organic search rankings, and the monetization appears to have been diverted from display ads, over to an affiliate program with a pet food company.  This site is proof that with the right systems and content in place, profitable affiliate sites are still out there to be created – even by the solo entrepreneur or the person who loves SEO as a side-hustle.
Many affiliate marketers use paid advertising to generate additional traffic to their site and drive more sales. Paid advertising on social media is often a good place to start, as these networks tend to be more affordable.You may also want to consider taking out inexpensive banner ads on small niche sites. Depending on your niche, Google AdWords could also be a good option to drive some paid traffic to your site.
Now you should have a pretty good idea of what niche you are going to get involved with. It is possible that you haven’t narrowed the list down to a single topic area, but you probably have found a few ideas that you feel real good about. Now at this point, it’s important to get an idea of how much money you can potentially make in your chosen niche. ClickBank is a great place to go to that search. First you browse top products in your category. If you don’t find any offers, that is not a good sign. It could mean that no one has been able to monetize that niche.

There are lots of affiliate site owners online, but very few of them can make a substantial monthly income from their business. This is due to lack of marketing skills and their personal experiences. Placing just a few affiliate links or banners in their sites can’t make a good money. Follow the expert ideas from the following best books for affiliate marketing and start maximizing your online income quickly. I have selected the 10 best books  for 2018 to successfully set up your  successful affiliate business or to improve it if you have already existing one.
Cookie stuffing involves placing an affiliate tracking cookie on a website visitor's computer without their knowledge, which will then generate revenue for the person doing the cookie stuffing. This not only generates fraudulent affiliate sales but also has the potential to overwrite other affiliates' cookies, essentially stealing their legitimately earned commissions.
Find a program — As we discussed earlier, many affiliate marketers find their merchants, vendors, or brands through affiliate programs. It’s important you determine your niche prior to finding a program, as some programs are geared toward certain types of products. If you’re interested in a particular affiliate program, look into what kinds of products it offers and whether it has any data on the success of its affiliates.
I have highlighted with red boxes how they are monetizing the site.  First I will point out how professional the site looks – it has a custom logo and a very clean look and feel to the site.  This helps build trust right away.  Secondly, I like how they have the salary data that searchers are looking for right away on top.  Then they have the adsense ads immediately following (still above the fold).
Hi, Jamie! Very good list. I needed something like this for 2018 so that I know what to target in the future blogs I create. As for now, I’m comfortable using SiteGround affiliate network and it’s pretty good actually. Their hosting service is pretty much the best considered its price. I’ve tried others but SiteGround stands out. I’ll also try new affiliate networks, something from the list you have just provided. I think Amazon is too saturated at the moment, and I need a better network. 2018 will be interesting indeed. 

This doesn’t mean you only sell one product. This means you build out a brand by selling varying yet adjacent products. Over time, your consumer network might consider you a go-to for which type of vacuum they should buy. Additionally, some industries pay more than others. Especially if the product is a harder sell, affiliates may get a higher cut than they would for a product in higher demand.
