As mentioned in some of my previous posts, online advertisers, affiliates and publishers use a wide range of payment calculation methods to price their online marketing campaigns. I have already explained what CPM stands for, so in this post I will try to explain CPA.
CPA, short for Cost Per Action (or in cases cost per acquisition) is a metric that measures how much you pay (or get paid) once a specified action (or acquisition) occurs. The action can be anything that you define, anything that is important to your business whether it’s a new client making a purchase, downloading an app or software, making a booking, a phone call or simply filling out a form to become a lead. In most campaigns however it usually refers to a new paying customer. Also if the action is defined as a lead registration rather than sale then the payment calculation will probably be referred to as a CPL (Cost Per Lead)
It is definitely considered to be one of the simplest and safest methods of running an online marketing campaign, because unless you get the action that you specified, you don’t have to pay. This makes planning and budgeting a campaign around CPA goals much easier both everyone involved. It’s a no-brainer why this is a great deal for advertisers as it allows them to have a clear idea what to expect for the amount of money they are willing to spend and plan their entire campaign strategy around this. As such I don't think I need to spend any time explaining a concept as simple as that.
I believe it’s more important to focus on the fact that CPA deals are also potentially great for publishers because they allow them to identify exactly what they need to deliver to their advertisers in order for them to get paid, but also to satisfy those same advertisers and get them to return and renew their campaigns on a monthly basis. Confident publishers, who know the quality of their traffic and how that traffic usually converts usually jump at the opportunity to work on CPA. This last part is also especially helpful to affiliates that are using their own resources (traffic, money, time) to generate commission income from affiliate programs.
If you are an affiliate or a publisher with high quality traffic that you know converts very well, a good CPA deal can make you a lot of money as you can optimize your campaign for conversions and make a lot more money.
Take the scenario below as an example:
As a publisher, you have been offered a nice CPA deal while you usually work on a CPM model. How can this CPA deal be better for you and make you more money? It all depends on the quality of your traffic and nobody knows that better than you. Let’s assume that you usually sell banner ad impressions on your site for $5 CPM. In order for you to make $500 you would have to sell 100,000 banner ad impressions.
If you were offered a CPA of $100 you could make the same amount by completing five of the defined actions. Depending on what your average Click-Through Ratio (CTR) is and what the average conversion ratio for your traffic usually is, you can estimate how possible it is to actually generate more than five actions using those same 100,000 banner impressions. Any action generated more than five is additional income for you, which you wouldn't be receiving if you were working on a standard CPM deal.
Some simple math:
100,000 Banner Impressions @ 3% CTR = 3000 clicks. Assuming just a 5% click-to-lead ratio, this would generate about 150 leads. A lead-to-action conversion ratio of 6% would generate 9 desired actions. At $100 CPA that’s $900 VS the $500 you would would have made by selling the same traffic on a standard CPM deal.
Now granted, in the example above I just used average industry figures for CTR, click-to-lead and lead-to-action ratios. You know your traffic better than anyone, use the formula above but substitute the figures applicable for your traffic to calculate what makes sense for you. Depending on the content of your site and the product you are promoting you may have lower CTR but higher conversion ratios or the other way around. It might also be that you need a higher CPA for this to work, for example a campaign with a lower CTR or conversion ratio might still make sense if the CPA is $150 instead of $100.
I am sure you can see the appeal and the great earning potential of a good CPA deal. Lastly I would just like to list some of the benefits for affiliates to being paid on CPA rather than Revenue Sharing:
- Faster commission generation – As soon as the defined action takes place you have already earned your commission.
- Less dependence on third parties – You get your commission when the defined action happened without having to worry about what happens next. You don’t need to wait until “if and when” the business will start making money in order for you to get paid.
- Lower Risk – You will lose less money if the advertiser or affiliate program, for whatever reason, decides to stop working with you as you will not miss out on revenue that you would might have received in the future
I will be discussing Revenue Sharing and other affiliate commission calculation methods in a different post in the next few days.
