If you’re getting less traffic, then you’ll still want to profit, so find higher paying affiliate programs that align with your content. Sure, you’ll be sending less referral traffic overall, but you can still make decent money since the payouts are higher.
In Pay Per Impression (CPM) you will get paid for every 1000 Impressions of your merchants advertisement. say the CPM rate is $0.25 and advertisement on your site gets 3000 impressions then you will receive a commission of 1000 x 0.25.

Studies show that people don’t hate ads—they hate bad ads. One aspect of a bad ad is irrelevance. Let’s say you run a fishing website. It wouldn’t make sense to run affiliate ads for a computer just because almost everyone probably has a computer at home. Your customers aren’t there for this type of content; it will confuse them, annoy them, make them think you’ve run out of content or, worst of all, make them think you’re trying to sell something shoddy to make a quick buck.
You should ensure that you address customer’s recent issues and how you are overcoming them in your ad plus add keywords and add a call to action as it would drive more customers when they would see the solution to their problems.
