Google Adwords is a “Pay Per Click” system, this means you can dictate where your ad appears through bidding for a series of phrases, but you only pay the amount you have bid for if someone clicks on your ad as a result of a web search.
How it works
The ads take the format of a short text ad that includes a title line, two short descriptive lines and a URL link to a website or a specific website page. The ads appear at the top and to the right of the organic search engine results. You can also pitch at what position on the page your ad will appear, through the amount you bid. Crudely this may mean the more you bid for a phrase, the higher your ad appears on page 1 of the Google Result.
Pay-per-click advertising has a quick set-up and money spent will immediately translate into clicks through to your site, while SEO campaign it could be months or years before you see the full benefit.
