CPM advertising networks behave pretty much as PPC networks, except that you get paid according to the number of impressions (i.e., page views) that the ads displayed on your site will generate. CPM stands for Cost per Mille, and it refers to the cost for 1,000 impressions.

A blog that generates 100,000 page views monthly displaying an advertising banner with a $1 CPM, therefore, will earn $100 monthly.

CPM rates vary with the network, the position of the ad and the format. The better the network, the higher the CPM rate (because they have access to more advertisers). The closer you put the ad to the top of the page, the higher the CPM. The bigger the format (in terms of pixels), the higher the CPM.

You can get as low as $0,10 and as high as $10 per 1,000 impressions (more in some special cases). CPM advertising tends to work well on websites with a high page views per visitor ratio (e.g., online forums, magazines and so on).

Google AdSense is the most popular option under this category, but there are also others. Basically you need to sign up with the network and paste some code snippets on your website. The network will then serve contextual ads (either text or images) relevant to your website, and you will earn a certain amount of money for every click.

The profitability of PPC advertising depends on the general traffic levels of the website and, most importantly, on the click-through rate (CTR) and cost per click (CPC). The CTR depends on the design of the website. Ads placed abode the fold or blended with content, for instance, tend to get higher CTRs. The CPC, on the other hand, depends on the nice of the website. Mortgages, financial products and college education are examples of profitable niches (clicks worth a couple of dollars are not rare), while tech-related topics tend to receive a smaller CPC (sometimes as low as a couple of cents per click).
