"I want to earn a few dollars with Google Adwords, without any real effort".

What are Google AdWords?

Google AdWords are little advertisements displayed on Google. These advertisements appear on the right hand side of the browser
every time a search is done on the Google search engine. Anybody including you and I can purchase advertisements on Google.

How do Google AdWords Work?

Google AdWords uses the pay-per-click method.

Pay-per-click just means that the advertisers pay a predetermined
amount of money every time someone clicks on their advertisement.
For Google, advertisers bid to have their ads shown when a specific search term is entered.

The higher the bid the higher on the page the ad will show. Being at the top of the page will get you more clicks than ads lower on the page.

Advertisers bid anywhere from $0.05 to $50 per click. That click sends the Internet surfers to a website address of the advertisers choosing.

The thing that makes this advertising method superior over other methods is that your ad will only be shown to people that are interested. It is a very targeted method that leads to more sales. Let's say that you are selling flowers. You would bid on the search term "flowers". When somebody does a search on Google for the term "flowers", your ad will appear.

On the other hand, when someone does a search for the term "dogs",

your ad will not appear because you did not bid on that search term.
You get to decide which search terms are relevant to your campaign and bid on that search term.
