Google AdSense is the most popular option under PPC Advertising, but there are others as well. Basically one need to sign up with the network and paste some code on their website. The network will then serve contextual ads (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 blended with content 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).
The source of the traffic can also affect the overall CTR rate. the traffic that comes from search engines (organic traffic) tends to perform well because these visitors were already looking for something, and they tend to click on ads more often. Social media traffic, on the other hand, presents terribly low CTRs because these visitors are tech-savvy and they just ignore ads.
