When the Nobel Prize winner Charles Townes had his epiphany one spring morning of 1951; for an invention his colleagues would later tease him of being irrelevant, he had absolutely had no idea it would improve businesses in a medium that was yet to be even created, the internet.

His invention of the laser, which is an acronym of "light amplification by stimulated emissions of radiation", is known for among other things creating precision.

There is nothing better than free cash. Earning money online however, is generally not free cash you have to do something. But there is a way you can get Google to pay for doing virtually nothing. The system is called Adsense. Basically what happens is that Google will place little ads on your blog or website that are relevant to the content of your webpage.

As an Adsense publisher, I am often annoyed to find my web pages filled with public service announcements (PSA) and ads unrelated to the content of my site. Fewer relevant ads mean fewer click-throughs and ultimately lower Adsense revenues. However advanced Google's contextual ad serving algorithm may be, it is still a computer program (as opposed to a human being) trying to figure out what a web page is about.

Starting as a new AdSense publisher would not be easy, there are lots of things you should be aware of, here are three most important things that you should never do with your AdSense account:

1. Signing to AdSense without fully understanding Google AdSense's Terms Of Services agreement

Unlike many other agreements you sign while browsing the Internet, you simply have no other option but to read and understand AdSense's Terms of Service or risk receiving a ban.

The online advertising world was dominated, just a few years ago, by banner advertising and pay per click ads were a term few webmasters and advertisers had heard of. However, banner advertising started seeing a steep decline in popularity and the all-important CTR (click through rate) as the banners got flashier and visually annoying. Their place was quickly taken by pay per click advertising, or PPC as it mostly referred to.

There are hundreds of thousands of web templates out there, but not all of them make for good Adsense templates. As the popularity of Google's Adsense program grew, many web designers started creating templates that allow for easy contextual ad integration. Making money online is now a possibility and you can win cash in no time with Adsense, once your business is set up.

We live in the information age, and there's just no getting around it. Information and news happens every single day, and savvy site surfers will expect you to update your content regularly. In fact, they'd prefer you to do that daily, or even hourly. And yes-I mean 24/7 hours. However, everyone needs to sleep. This article will discuss how to create fresh and regular content for your adsense websites through really simple syndication.

Tired of seeing clicks that are paying your $0.05? There is something you can do about it.

The biggest outcry for pretty well all adsense publishers is most often about low paying click values. If you're wondering why Google is only paying you $0.05 a click, you should not need to look much further than the content on your web page. Remember, your revenue is a part of the amount advertisers are willing to pay for respective keywords.

You've been trying for months, maybe years now, to make your website profitable.

All you hear about is how people are setting up one income stream after another. They build a website and it turns into a little money well for them, then they move onto another site, another niche, another market and repeat the process.

How do they do it and more to the point why aren't you?

This is the question not just on your lips but on thousands of webmasters around the world.

Is it still possible to make a good income with Google Adsense? After all, there was a report circulating this past fall that said Adsense was dead.

Adsense took a beating a short time ago when Google made some changes. But it is still possible to make some extra money with a Web site or two. It is even possible to make a good living with it.
