The Google Adsense program is a main online income source. It truly is really simple to use and is minimal in upkeep and maintenance which is perfect for online businesses.

The best way to get started using Adsense is with a blog. You start a blog and write about something you are very interested in. That makes it easy to write multiple entries about the same subject. Your blog should focus on one theme. In other words, don't create a blog or site and add multiple interests or hobbies on the same site. Create one blog or site per interest. For example, let's say you love dog breeding and you also love sky diving. You would not combine your two interests on one blog. That confuses your theme and you would not get proper adsense ads targeting from Google based on your content.

Google owns Blogger and of course, it is ready to go with Adsense right out of the chute. All you have to do is sign up for a Google Adsense account number to plug into the system.

If you don't like the idea of using Blogger, you can buy a domain for your theme (like www.JaniceLovesDogs.com) and start a blog using a free blog software like Wordpress. You need to be just a little more tech-savvy in order to set up your software the way you want it on a server, but it is worth it since you actually own your site and you can sell your site later, if you want to. But you probably won't want to after you build up your content, traffic and sales from Google Adsense!

Adsense is pretty straightforward.

Google has a database of content that is based on what people post on their websites. In order to determine what a website is about, Google uses a series of techniques that basically counts the related terms on a website based on repetition of the terms and the definition or correlation of those terms.

Google also knows what popular search terms people use when searching for products, services or information. They maintain a database of this information also. When words or specific phrases are popular and used a lot, these are described as "key words" and "key phrases'.

When Google wanted to start a program to make money for Google, they came up with Adsense. They sell the popular key words and key phrases to the highest bidders.

In order to advertise these ads, they started showing the ads on search engine results pages when average web users searched for those terms. In order to make even more money, Google decided to expand their ability to make money. The ads would be allowed on web sites that had content the same as the key word ads so that visitors to the individual websites would see ads that were relevant to what they were looking for on the website.

Google established a huge presence on a good number of the websites across the globe by establishing the Adsense program. The program is much more far-reaching than just displaying the ads on Google search engine search results pages.

1.  You sign up for a Google Adsense Account and you are assigned an account number.
2. You establish a site or a blog that will serve your content and your Google Adsense.
3. You log in to your Google account and pick the Google ad structure you would like to display (horizontal, or column, number of ads to show, colors, etc.) and Google then generates a code for you to paste into your web page(s).
4. After you add the code, Google may take a few hours or so to scan and "experience" the type of content on your site so that it can match ads to compliment that content. For instance, if you have a camping site, Google would perhaps send Adsense ads that  Coleman bought or ads that a tent manufacturer bought to be displayed for the users on your site.
5. If someone clicks on an ad on your site - you make a percentage of the ad price paid by the advertiser to Google. Google shares their ad sale with you because you are helping them to distribute the ads to targeted, interested potential customers.

What a great system.
