Pay-per-click (PPC) Advertising is a method of internet advertising available on search engines, content websites, blogs, industry specific websites, even trade magazine websites;, where you only pay when an internet user clicks on your ad which leads them to your website. On search engines such as Google, Yahoo and MSN, you bid on keywords that are relevant to your business; what people would type into the search engine to find your business. When someone types one of your keywords into the search engine or is on a page that has relevant content to your site, your ads may be displayed. These ads are called sponsored links or sponsored ads. They appear above and on the side of the organic search results, and just about anywhere on a content site. Content websites usually charge a set price per click instead of using a bidding system.
