Google Adwords is a program that allows you to create tailored ads to show on the Google’s search engine results pages along with other affiliate sites. It allows you to create an advertisement and then set parameters to show the ad, such as location, time and most importantly keywords / phrases.
When the ad is clicked by a visitor, the website owner will be charged a specific amount for that click.
Google Adwords can be a little costly, especially if you are targeting generic high competition keywords but can work really well. It is ideal if you have a new product or service that you are launching and want to get instant traffic to your website and also if your website has recently gone live and not yet been indexed by the search engines.
You can set up a daily budget with Adwords to ensure you keep tabs on what you are spending and set the ads to turn off once this budget is used up. You will need to monitor your campaigns closely in the first few days / weeks and make amendments where necessary .
