Performance-based advertising

With performance-based advertising, the advertiser pays only for measurable results.
With other forms of advertising they pay regardless of results. Performance-based advertising is becoming more common with the spread of electronic media, notably the Internet, where it is possible to directly measure user actions that result from the advertisement. In fact, over half of all internet advertising is performance-based today.




There are four common pricing models used in the online performance advertising market.
CPM (Cost-per-Mille, or Cost-per-Thousand) Pricing Models charge advertisers for impressions - i.e. the number of times people view an advertisement. Display advertising is commonly sold on a Cost-per-Lead pricing model. The problem with CPM advertising is that advertisers are charged even if the target audience does not click on the advertisement.
CPC (Cost-per-Click) advertising overcomes this problem by charging advertisers only when the consumer clicks on the advertisement. However, due to increased competition, search keywords have become very expensive. A 2007 Doubleclick Performics Search trends Report shows that there were nearly six times as many keywords with a cost per click (CPC) of more than $1 in January 2007 than the prior year. The cost per keyword increased by 33% and the cost per click rose by as much as 55%.
In recent times, there has been a rapid increase in online lead generation - banner and direct response advertising that works off a CPL pricing model. In a Cost-per-Lead pricing model, advertisers pay only for qualified leads - irrespective of the clicks or impressions that went into generating the lead. CPL advertising is also commonly referred to as online lead generation.
Cost per Lead (CPL) pricing models are the most advertiser friendly. A recent IBM research study found that two-thirds of senior marketers expect 20 percent of ad revenue to move away from impression-based sales, in favor of action-based models within three years. CPL models allow advertisers to pay only for qualified leads as opposed to clicks or impressions and are at the pinnacle of the online advertising ROI hierarchy.
In CPA advertising, advertisers pay for a specific action such as a credit card transaction (also called CPO, Cost-Per-Order).
Advertisers need to be careful when choosing between CPL and CPA pricing models.
In CPL campaigns, advertisers pay for an interested lead - i.e. the contact information of a person interested in the advertiser's product or service. CPL campaigns are suitable for brand marketers and direct response marketers looking to engage consumers at multiple touchpoints - by building a newsletter list, community site, reward program or member acquisition program.

In CPA campaigns, the advertiser typically pays for a completed sale involving a credit card transaction. CPA is all about 'now' -- it focuses on driving consumers to buy at that exact moment. If a visitor to the website doesn't buy anything, there's no easy way to remarket to them.
There are other important differentiators:
1. CPL campaigns are advertiser-centric. The advertiser remains in control of their brand, selecting trusted and contextually relevant publishers to run their offers.On the other hand, CPA and affiliate marketing campaigns are publisher-centric. Advertisers cede control over where their brand will appear, as publishers browse offers and pick which to run on their websites. Advertisers generally do not know where their offer is running.
