How Split Testing Your CTA Will Boost Your Business

What is your reason for sending emails? To get subscribers, to get customers, to make sales to previous customers? Whatever your goal is, you’re always looking for your recipients to DO something.

So you include a call to action (CTA). Your CTA is what drives someone to do what you want them to do. If you’re not confident in your CTA, there is a quick fix for you!

That’s right… a split test.

CTA, like sign up forms and subject lines, are awesome to split test. The right call to action can drastically affect your email campaign and truly drive your business up. Split testing is the perfect way to make sure you’re putting the best call to action out there.

Variables to Test?

When it comes to a call to action, the smallest change can have a huge impact. And there are a lot of things you can change.

The Daily Egg, a blog for conversion optimization, design and copywriting tips, highlights six variables to consider when designing a call to action.

  • Size (How big is the link? Will people notice it right away?)
  • Color (Does the button stand out?)
  • Text (Do people understand exactly what will happen if they click?)
  • Position (Do people have to scroll to see the button?)
  • White Space (Is the link getting lost in the clutter?)
  • Special Effects (Does the button attract attention because it stands out from the page?)

We’ve tested some of these variables ourselves over the years.

Are buttons best?

In our early days of sending out broadcasts that linked to our blog, we were trying to build our following. We wanted to know if people were more likely to click on a noticeable button, or if they would respond better to a text link. So we ran some tests.

At first, the button was getting significantly more attention. It was bigger, it stood out from the rest of the page, and the call to action really jumped off the screen.

But within the first few tests, the text link beat the button once by a significant amount. We couldn’t let this go unexplored, so we continued to test.

Eventually, over about 40 tests, we determined the text links to be a better call to action for us. Once the novelty of the button wore off, our subscribers seemed to be more comfortable with the less glaring link.

What words work?

The phrasing of the CTA can also have the enormous impact on it’s success. Copyblogger explored the impact of the words “Click here” in opposition to more creative link text that could help search engine optimization, using data from Marketing Sherpa.

Their findings brought us back to our roots: “Click here” is the most effective way to get someone to… well, click there. Marketing Sherpa tested their initial call to action (“Continue here…”) against three other options. This was the impact on their clickthroughs:

Here were the differences in clickthroughs:

  • “Click to continue”: 8.53%
  • “Continue to article”: 3.3%
  • “Read more”: (-)1.8%

“Click to continue” was the clear winner, and they quickly changed their call to action.

Colors creating clickthroughs?

ConversionXL compiled a the findings of tests that pitted red buttons against green buttons.

Red, as a color, can signify both dominance or danger. So what does that mean for a call to action?

Over the course of three case studies, where the only difference between buttons was the color, red beat out green 3 out of 3 times.

What does this mean for you?

Get testing! Just because text links work better for AWeber and red buttons beat green buttons in a few tests, doesn’t mean that either of these findings are what’s best for you.

Consider your audience, your objective, and your strategy to build your business. Make your call to action work for you!
