Pay Per Click advertising is one of the most popular on the Internet as advertisers only pay for actual clicks on their advertisements and users subsequently delivered to their landing pages. Google, for example, has a pay per click advertising programme as part of their AdWords system allowing webmasters to advertise at the top of the search engine results in exchange for paying for each click received.
This advertising also extends to content sites such as news sites and blogs through partner programmes such as AdSense. In exchange for displaying a block of advertisements on their sites, webmasters receive a share of revenue generated by AdSense which is often driven by a PPC model with advertisers paying for each click.
The cost of PPC advertising can be high and as a result it’s important to carefully test and plan campaigns. Many big campaigns will be for $1000s of dollars per day. Initial testing for those campaigns could be for as little as $20 per day as the campaign is tuned up testing different landing pages, keywords and advertisement text.
