How to use A/B (split) testing to optimise donations on your charity website

How to use A/B (split) testing to optimise donations on your charity website

You may have come across the concept of A/B or split testing before, but have you ever used it to boost donations?

A/B testing enables you to randomly serve two different versions of a webpage so you can collect data on which performs best. In a simple A/B test, half of your potential donors will see one version of the page and the other half will see the other.

By monitoring and tweaking your donation page based on real data, you can increase your conversions rate and drive more donations.

Choosing what to test on your donations page

Where do you start when it comes to A/B testing? While there are no hard and fast rules, it makes sense to start on those page elements that are most visible to potential donors. These might include your featured page image, page title/heading and donation button.

You can then start focusing on more subtle elements of your page such as the suggested donation amounts and different form layouts.

It can help to break down a webpage into visuals, text, layout and process, as follows:

Images can be highly emotive and a simple image change might increase conversions significantly. This is where I'd start in any A/B donation testing.

Visual elements

These include your featured page image, the colour scheme of your webpage and the colour and contrast of your donations button. The font style and size can also be included here. Images can be highly emotive and a simple image change might increase conversions significantly. This is where I'd start in any A/B donation testing.

Text elements

These include the actual page copy, your page title or headline and the text on your donation button.

Are you addressing your target audience? Does your headline attract attention and does it link directly to your copy? Does 'Click to support our cause' convert better than a simple 'Donate now' button?

You can also test whether you should include information about how donations are spent, key statistics or social proof. If you offer the choice between one off and regular donations, can altering your text increase recurring donations?

Page layout

Where is your donation button on your page? Does it appear as a pop up? Is it on a 'sticky' header that follows your reader as they scroll? All of these elements can be tested.

Donations Process

Some donations can be completed in a click while others are set out in a step-by-step process. Try both ways and see which converts better.

Do you include a suggested donation amount? You can try varying this up and down or omitting it altogether. In this case, you will want to track both conversion numbers and overall amounts. If setting your suggested donation higher leads to a drop in donations but an increase in revenue, you might experiment further to find the optimum numbers.
