1. Sign up for a Google Adwords account by clicking 'sign up' on the Adwords homepage. You need to provide personal data in order to create ad campaigns, such as billing information. Each Adwords account is subject to a $5 activation fee upon entering credit card or bank account information.
2. Create an advertising campaign. Choose your advertisement's title and description and enter the address of the web page that you want potential customers to visit.
3. Choose keywords for your campaign. In order to place your ads on relevant searches and web pages, you need to provide a set of coherent keywords and key phrases. For example, if you are advertising dog food, you would use the key phrases 'dog food' and 'puppy food'.
4. Customize your campaign. You can choose to limit your advertisement's audience to geographical locations or languages. You can also control what times of the day your ad appears.
5. Monitor your results. See if the traffic coming from Adwords advertising is helping to increase your website's sales. If you still see no results after a reasonable amount of trial and error, try tweaking your campaign settings or moving on to a different promotional method.
