Google AdSense is the program that can give you advertising revenue from each page on your website with a minimal investment in time and no additional resources.AdSense delivers relevant text and image ads that are precisely targeted to your site and your site content. And when you add a Google search box to your site, AdSense delivers relevant text ads that are targeted to the Google search results pages generated by your visitors’ search request.

Optimizing Google Adsense For Better Performance and More Money!Link UnitsLeaderboards & SkyscrapersSquare & Rectangle Ad UnitsFiltering Adsense AdvertisersOne constant that holds true with AdsenseShould you add Adsense to your website?If you own a small company that has a brochure type website that gets maybe 50-100 visitors a day, I recommend NOT adding Adsense to your site. It will never make enough money with that kind of traffic. Remember: Your Adsense campaign needs to make over $100 to get paid out.If your company receives around 500-1000+ visitors a day, you can now start considering to make money through Google. Adsense is all about numbers. Play the numbers to make more money. In fact, try making goals for yourself to make X amount of dollars through your Adsense account by a certain time. Doing this will only increase your business and make your company more powerful online by increasing the amount of traffic it receives. For multiple websites, channels are important:

Google allows you to track the performance of multiple websites all in one account which ultimately gives you the ability to track how many visitors you're getting for each website. It also allows you to work harder on those sites that aren't up to par.I consistently look at each individual website channel to work harder at promoting the ones that aren't performing well. By doing this, we increase the amount of promotion going into the websites that under perform, and in turn eventually increase the business for those websites as well. The more you promote your website, the more the exposure you will ultimately deliver for your Adsense campaign and your company.

Google Search with Adsense:To top all that off, you can add Google search within your site to give visitors a search function for your content and to allow people to also click on your Adsense program. Please note that for Google search to work, your website and all of its content pages must already be indexed by Google. Adding the Google search bar to your site right away won't help your visitors at all.
