We’ve all been in those meetings that get down into the nitty-gritty. Should this push notification include an exclamation point? Should this subject line be quick and concise or a little more descriptive? Is our website banner the right shade of blue?
If you asked a random person on the street one of these questions, they’d look at you like you’ve lost your mind. But for you and your fellow marketers, you know how crucial some of these questions can be. And you know that answering these questions correctly could make the difference when trying to craft a successful marketing campaign.
But wait—how do you know if you are correct? Do you just have to make a decision, say a quick prayer to the marketing gods, then launch your campaign?
No. Of course not. That would be scary. And probably end badly. So to avoid this risk and make sure they’re launching the best campaign, the best teams are constantly testing.
What do you mean by testing?
Good question. When we talk about testing, we mean launching and comparing different variants of your messaging campaign. These variants may differ in copy details like subject lines, aesthetic details like color or use of GIFs, or even in the offer, itself—and testing gives you the data you need to understand which variant resonates with your audience the most. This helps you understand which version of your campaign delivers on key engagement metrics most effectively before actually launching your campaign to your entire audience.
So what tests should I be running?
There are a few different types of tests that you should be aware of. Luckily they all have the same general goal: to give you a valuable sample of data about your audience before launching your campaign to the masses. Here’s the tests to know and the situations that call for them:
For instance, you might want to understand how changing your subject line and the CTA button in your email influences conversions. In this case, you’ll have four variants:
So while A/B testing gives you a yes or no answer about an isolated aspect of your campaign, multivariate tests compare different versions of your campaign on a more holistic level and study how different variables within your campaign interact.
But wait. Who’s seeing these variants of my campaign?
Another good question. If you’re sending these variants to all sorts of users, you’ll possibly launch a subpar version of your messaging to a significant group of users. That’s why it’s important to get just the right amount of data to inform your test results. But how much data is too much...or too little?
The general rule of thumb: 10%. You send Message A to 10% of your audience and Message B to another 10% of your audience. Then if Message A wins, that’s the message that gets sent to the other 80% of your audience. This is a rule of thumb for a reason, as these percentages typically yield a statistically significant “winner.” But not always. So it’s worth looking into more advanced methods that leverage all sorts of fancy statistical mumbo jumbo.
In general, A/B tests require less traffic to determine a statistically significant result. For a really high traffic campaign, it may be worthwhile to run a multivariate test, though know that it will require you to dip into a larger portion of your traffic in order to get a statistically significant result.
How often should I be testing?
Oh you know, only constantly. In reality, the teams that are consistently turning out successful campaigns are investing in ongoing testing, which supports constant iteration of your messages, campaigns and strategy.
So while testing to settle isolated debates is of course valuable, you should be testing regularly so that you always have data about your campaigns at your fingertips. Then there won’t be anything to debate. You’ll always have a fairly good idea of what’s working and what needs some more thought.
