Whether you have one dollar or thousands of dollars to spend per day on your Facebook ads, keeping costs low by serving great ads is the name of the game. But what you think is a great ad may not actually be the greatest ad. With A/B testing, you can systematically nail down what the data says is the perfect ad for your audience.

But while Facebook A/B testing can help you to lower costs, you may be looking to lower costs precisely because you have a low budget. That’s why we’re going to focus on how to run effective A/B tests in a cost-effective manner.

Why Facebook A/B testing is important

Competing in Facebook ads means you can’t just set it and forget it. Once you launch a campaign, it won’t run consistently—you will need to check in on it, analyze performance, test constantly, and continue optimizing in an effort to see success. Here are some other reasons to run Facebook A/B tests.

Facebook is finicky. What works well for some time may suddenly shift due to algorithmic changes or, quite often, unknown or irrational reasons.

Lower costs. With testing, we can learn, gain valuable insights about our audiences, find out what does and does not resonate with them, and lower our costs over time.

Reach your whole audience. What may captivate one user in an audience may not with another, so it’s best practice to always run tests in your campaigns.

For example, our custom window insert client, Indow Windows, saw a dip in their lead volume and an increase in cost per lead for one lower-funnel ad set.
