Do you have a high traffic website or are you looking to monetize the footer of your website with CPM Ads? I have compiled a list of the best CPM ad networks that a publisher like you can join & start earning money.
What are CPM ads?
CPM (Cost per Thousand Impressions) based advertisements are a great way to earn income with your blog. CPM advertising pays you according to the amount of impressions received on an advertisement.

An “impression” means a single instance of an advertisement appearing on your website. This means that even if your readers are not clicking on your blog’s ads, with CPM ads, you can still be paid.
Note: To ensure a better income from CPM ads, be sure to place them in prominentpositions on your site.
