Google AdSense is the Google program where you can host pay-per-click ads on your Website. When someone clicks an ad, you earn money. Simple as that.
Is it really as easy to make money with Google AdSense as many would lead you to believe? Now that I've become heavily involved with managing Google AdSense programs for my clients, I can see it's not all play and no work.
Google AdSense Payments
Google will not issue an AdSense payment until your earnings exceed $100. Unfortunately, there are loads of Google AdSense Forum entries about website operators who accumulated $90 or more in click through earnings only to get banned from Google and not get paid anything at all before they ever reached $100. This may be because Google doesn't take a close look to see if you're complying with their guidelines until it comes time to pay you. So yes, there's a lot more to the story than meets the eye.
Google AdSense for Search - This places a search box on your Web site. When a user enters a term and conducts a search, a search results page opens, that hosts more pay-per-click ads. You can customize the color scheme of the search results page to harmonize with your web site.
