You can also choose to have your AdWords campaign appear across Google’s Content Network, a network of content sites that have partnered with Google. This will give you an even broader reach than just having your listings show on the search engine results pages. However, many beginners avoid the Content Network as it the traffic is less targetted than the Search Network listings.
In order for you to keep control of your Pay Per Click ad campaign, Google allows you the option of keeping your ad from appearing on specific sites, or sites that have specific content that you do not find acceptable for your advertisement.
Google allows you to bid between $0.05 and $100 for each keyword or phrase that you wish to bid on. Then, when someone searches for that keyword or phrase, if you have bid high enough, your ad will appear on the right hand side of the search results page. Everytime someone clicks on your ad, you are charged up to the amount that you bid.
Google Adwords requires a one-time $5.00 activation fee when you set up your account. After that, there are no monthly minimums or maximums that you must spend. You have complete control over your pay per click advertising campaign, with the ability to start it or stop it whenever you want to.
Google Adwords offers many tools to help you choose the perfect keywords for your product or service, and many customizable reports that will help you keep track of how well your pay per click ad campaign is doing. Even though Google Ad Words isn't technically a pay per click search engine, it is currently the top pay per click program ahead of Yahoo Search Marketing - formerly known as Overture.
