Google AdWords is an online advertising service developed by Google, where advertisers pay to display brief advertising copy, product listings, and video content within the Google ad network to web users.

Based partly on cookies and partly on keywords determined by advertisers, Google uses these characteristics to place advertising copy on pages where they think it might be relevant and advertisers pay when users divert their browsing to click on the advertising copy.

Google’s text advertisements are short, consisting of one headline with a maximum of 30 characters, two text lines of 35 characters each, and a display URL of 40 characters. These mimic what the average search result looks like on Google, so knowing what to advertise and how best to capture your audience is important.

An AdWords campaign offers services such as pay-per-click (PPC) advertising and cost-per-acquisition (CPA) advertising and are one of the biggest and most effective methods of online advertising in the world.
