Just like ClickBank, Commission Junction is an advertising platform that works with suppliers. Commission Junction works with big brand names. But they are still a middleman. You won’t be working or dealing with the individual companies yourself, which can be nice and can be a pain. Commission Junction does have higher requirements for joining their program. It’s not impossible if you’re serious about affiliate marketing.

Stands for Return on Advertising Spending, also shortened many times to Return on Ad Spend and can also be referred to as ROI. It refers to the amount of money made as a result of a specific advertising campaign. To find the ROAS of a campaign, you take the revenue divide it by the ad spend and multiply the result by 100. The result is presented in percentage form. Example – if you spent $200 to run a campaign and you made a gross profit of $600, you would take $600 (revenue) and divide it by $200 (ad spend) to get 3 and then multiply that by 100 to get 300 – displayed as a 300% ROAS. The amount over 100% using this method of calculation is your profit. In this example, that would mean you received a 200% profit on the campaign.

One great way to get ideas for related products to promote is to look at the stats/reports that Amazon gives you to see which products readers are buying. After a while you’ll start to notice that they’re not only buying the products you directly promote but other products as well. Some will be completely irrelevant to your niche – but many times trends will emerge that could signal other products that it might be worth promoting.
Because Amazon has a huge selection, and it’s so easy to generate an affiliate link for just about any product, it can be easy to fall into the trap of promoting an Amazon product without getting to know the product first. As a result, it can be really easy to start promoting something you don’t know very well, and risking the trust of your audience in the process.
Robey is particularly rankled by the distinction between “beauty” and “luxury beauty” — a difference between a 6 and 10 percent commission under the new system. Almost none of the products she covers are grouped in Amazon’s luxury beauty category, although she considers many of them luxury goods. The result is a major incentive to write about brands in the favored category, although Robey says she won’t change the products she writes about.
And what about joining another company's affiliate program? It's all about extra revenue. Think about your customers' needs: What other products or services would interest your site visitors? Join those affiliate programs. Affiliate programs can increase your sales with no upfront cost to you. It just takes a little time to plan your strategy and select the partners that will have the greatest impact on your business.
