PPC Advertising (pay per click advertising)

Pay Per Click (PPC) is an advertising model in which advertisers pay only when their ad is clicked. Basically you 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 web traffic and, most importantly, on the click-through rate (CTR) and cost per click (CPC).
The CTR depends on the design of the website, ad size, ad placement and some other factors. In accordance with the latest Chitika's researches and their new click-prediction technology such factors as user opereting sistem, WEB browser, source of traffic and educational level greatly influence CTR. For instance, do you know that IE users are twice as likely to click on an ad as FireFox users or that CTR of users who come via Bing is over 75% higher than those who come from Google? (see complete results of this reserches).
These types of statistical studies are the core of the new predictive technology. (This type of analysis is common in other industries such as insurance, credit cards, etc., and now Chitika is bringing that to online advertising. )
The CPC mostly depends on the content of the website, the source of the web site traffic and CTR. Financial products, mortgages, and college education are examples of profitable niches (clicks worth from a couple to tens 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). Last months we observe the tendency of CPC increasing.The cost per click for some Google AdSense keywords rose up to $100 per click. (See the list of top paying Google keywords)
