Just today i learn about Google Adwords.
AdWords is Google's flagship advertising product and main source of revenue ($21 billion in 2008)[1]. AdWords offers pay-per-click (PPC) advertising, and site-targeted advertising for both text and banner ads. The AdWords program includes local, national, and international distribution. Google's text advertisements are short, consisting of one title line and two content text lines. Image ads can be one of several different Interactive Advertising Bureau (IAB) standard sizes.
Advertisers specify the words that should trigger their ads and the maximum amount they are willing to pay per click. When a user searches Google's search engine on www.google.com or the relevant local/national google server (e.g. www.google.co.uk for The United Kingdom), ads (also known as creatives by Google) for relevant words are shown as "sponsored links" on the right side of the screen, and sometimes above the main search results.
Here in Adwords you'll pay people for visiting your sites through PPC (Pay per clicks) opposite in Adsense coz in Adsense were paid for every click on the ads that we post. In Adwords you can set allowable budget everyday per clicks and how much per clicks.
Not bad for promoting your business. Lots of advantages: Most people are into internet now a days,you can have more audience/possible buyers not just in your country but internationally, aside from that Google is your partner most people used the said provider and people rely on it. Who else don't know about "Google".
