1. Create a free Google Adsense account by going here:https://www.google.com/adsense/login/en_US/
2. Write some articles and information that you can populate your website or blog with. This is very important because you need to have content on your website or a blog that is clear, informative, useful, and discusses something that people will want to read about and learn and which can also be considered a niche topic. For example, lets say that you know a lot about gardening - then make gardening articles your niche and try to really focus your articles on specific topics related to gardening. Always write your own content, and never plagiarize other people's work!
3. Get your site or blog up and running, log into your Google Adsense account, and copy and past the Google Adsense code into your web pages that have the content so that your ads will be targeted to your content. You want to target ads to your content, because as your audience see an ad that makes sense to them, they will click it, and you will make money.
4. Pay attention to your keyword density. What does this mean? You want to make sure that you optimizing your website with the correct keywords that are specific and relevant to the information people will find on your site. Google Adsense uses your keywords to serve up ads, so if you are writing about gardening, your keywords should encompass gardening and gardening topics.A really cool tool out there which will help you see what type of ads will be served up on your site based on your keywords is here:http://www.resultsgenerator.com/adsense/Go here, type in your keywords, and see what comes up! If the ads seem out of place to your site content and offerings, then you need to change your keywords.

5. Make sure that you keep your content focused and relevant to the niche topic that you are writing about. Remember the example we used earlier about gardening, and trying to keep the topics specific. This is important because Google Adsense will serve ads on your site that are based both on your keywords and on the content in your site. You want your keywords and your content to match as closely as possible so that you are serving relevant ads to your audience on your site. This is important because as they read your articles, they might see an ad that they would want to click on about flowers or gardening tools.
6. It is also important to chose the ad types that Google Adsense offers which will generate the best click-through rate from your audience. As you play with Google Adsense, you will notice that there are a lot of different ad types to choose from: rectangles, skyscrapers, squares, text ads, images, etc. The top four formats I recommend you use are:468x15 text ads
336x280 large rectangle
300x250 medium rectangle
160x600 wide skyscraper
7. Once you have chosen the format you want to use, make sure that you pick a color scheme that will blend the ads into your overall site design well. Make the border color and the background color the same color as your web site and the text color black or the color of your content.
8. Finally, once you have done all of the above steps, written some articles, implemented your Google Adsense ads into your site, and formatted everything correctly - you will want to keep your site or blog content fresh and updated! The more you write, and the more articles or content you have, the more visitors you get. Set a goal to try and write a new article everyday to keep your site interesting and your visitors interested in what you have to offer.
