There are many ad networks out there that allow webmasters to make money on. Ad networks provide a place for webmasters to manage zones where each zone has a list of ads. These zones can then be applied to a webpage as a whole or parts of a web page(Google Adsense, Adbrite Zones). Indirectly they provide statistics on page views and the number of clicks on that page. Big ad networks like Google Adsense, Yahoo! ads and Adbrite allow webmasters to select from a variety of ad types such as video ads, image ads and text ads or a combination.

Google adsense in particular has a powerful relevancy engine wherein the ad contents are based on the page content. So if the webpage was about cars, the ads would be about cars. This is a very powerful technique in delivery a higher click rate. People are on that car site to look for cars so naturally if they find hot deals or interesting links to more cars they are more likely to click. The amount of money made by webmasters depends on the amount of traffic they get. Greater traffic means higher click through rate, that is each click will be worth more if there are more visitors. Money can be made per click or the webmaster would gain commission if the user bought something.

Unscrupulous webmasters can create robots that automatically clicks their ads but these plans generally fail or their accounts get locked up once they get caught. Again, short term gains are not worthwhile unless you want to be a full blown criminal. There are many crafty algorithms out there but almost all of them require a botnet to execute. Search engines are very good at finding proxies and bots or checking if 20 clicks came from one source in 2 second intervals.

The Internet is littered with ads everywhere. People have come to even ignore banner ads as if they don't exist. More effective advertising schemes are ads embedded within documents at stages throughout the content(Hemanth Dondolu,interview). Users who read down that far are probably more interested in what the content has to say and what the ad would have to say; assuming the ad was relevant.

When people say that the Internet has been so commercialized, to the common person who sees it daily they just don't realize how commercialized and how dangerous it really can be on the world wide web. Millions of dollars are exchanged daily and those domains with PR 8 and PR 9 are making just as much monthly. As we can see porn.com sold for 9.5 million dollars and to normal people that may seem like "Wow" or "Insane!" but to the people who bought the domain, it was probably a steal.

The adult entertainment rakes in extremely large profits assuming you can get in with the right networks. It may seem like they are just pictures and videos posted everywhere but the amount of advertising and effort poured into a page is unimaginable. It's often not the design that makes the page but the SEO that makes the page.

New algorithms for search engines are appearing frequently and nothing is concrete. The old ways of meta tag analysis to linguistic algorithms was a significant leap in technology and computing power. What happens when all possible domains are taken? Would anyone want to memorize a really long URL (web address) which in fact, would defeat the purpose of having a URL since the ip address equivalent is a 32 bit number in the format of (xxx.xxx.xxx.xxx). Meaning if we did a reverse lookup on Google.com we come up with 64.233.167.99 so typing http://64.233.167.99 into the browser bar would yield the same result. New techniques to manipulate these search results appear just as fast and the number of privacy concerns just keep piling up. Nevertheless, useful commercialization of the Internet is always positive and a good contributor to the economy and has made living and convenience much more practical than ever.
