Google Money Making Ad-Options.
Google offers three ways to make money from them:
Google AdSense for Content – there are many size and shape of ads ads for placing in your content available in adSense . These can be text or image ads and also can be both - you specify what you need for. Ad units are full ads. Link units are simply a strip of text links that your visitors might want to click. Google allows you to put up to three Ads Units and one Link unit on each page of your Website/blog, provided you follow its policies - both for AdSense and for Webmasters.
Google AdSense for Search – place a Search box on your website/blog. When a user enter a term and find something in search, a search results page opens, that hosts more PPC (pay-per-click ads). You can customize the color scheme of the search results page to harmonize with your website/blog.
Google Referrals - Here you make money by referring visitors to use a Google product, like AdSense, AdWords, the Google Toolbar and other Google software. Just like Google AdSense for Content and AdSense for Search, Google generates the code that you paste into the desired location on your webpage. You can choose from a wide variety of buttons or text links of different colors. As an example of how Google Referrals works, if someone goes to your site and clicks the link and signs up for an AdSense account, when that person earns a $100 from Google AdSense and receives a payout from Google, you'll also receive $100 for referring them. This is a great idea to me, because you can be the world's worst Google AdSense advertiser, but if an ad dynamo happens to visit your site and uses your referral link, you can make money anyway.
