Cost per mille requires only that the publisher make the advertising available on his or her website and display it to the page visitors in order to receive a commission.

Google Trends - A good tool for understanding seasonal content. It also displays results in a more visual way but presents much simpler results than Keyword Planner. It shows interest in keywords and search queries, but doesn't give you the exact number of searches or your organic position. It is definitely worth having with Keyword Planner, but I wouldn't recommend only using Trends.
As mentioned merchants will pay publishers a certain commission when they’re directly responsible for driving a sale. So when you look for merchants to write about, or products you want to review, keep in mind what commission rate they pay. The better the rate, the more money you’ll make if you drive a sale. If you can combine a high commission rate with a product you believe in you’ll have struck gold.
