A/B Testing for PPC Campaigns: Is it Worth it and How to Do it Right

Pay-per-click (PPC) advertising can be a powerful way to drive traffic and leads to your website. But like any marketing effort, optimizing your PPC campaigns is crucial for getting the most bang for your buck. One optimization tactic that is growing in popularity is A/B testing – trying out two different versions of an ad, landing page, or other campaign element and seeing which performs better.

Let’s explore when and how A/B testing can benefit your PPC campaigns with advice from experts in PPC in St. Catherine, Canada.

Split Testing Overview

A/B testing, also known as split testing, is a controlled experiment where two versions of an ad, landing page, or campaign variable are shown to a segment of traffic. The performance of Version A is compared to Version B to statistically determine which option drives more conversions and revenue.

Some examples of things you can A/B test for PPC include:

  • Ad copy
  • Ad formats (responsive, static, etc.)
  • Landing page layouts
  • Call-to-action placement or wording
  • Offers or discounts

By making data-driven decisions backed by split test results, you can optimize your PPC campaigns for higher profits.

Components of Split Testing

There are a few key components that go into setting up and analyzing a split test:

Test Group & Control Group – Traffic is randomly divided between a control, which sees the original version, and a test group, which sees the variation you’re testing.

Sample Size – You need enough conversion data for each variation to produce statistically significant results.

Test Duration – Tests should run long enough to achieve the minimum sample size. 2-4 weeks is common.

Tracking & Analysis – Tracking metrics like CTR, conversions, cost per conversion, and ROI then comparing performance.

Significance Testing – Statistical tests determine if the difference between groups is significant, not just random chance.

How to Structure Your A/B Tests

Follow these best practices when developing and implementing A/B tests:

  • Limit one variable – Only test one change at a time between the A and B versions. More variables can skew results.
  • Prioritize what to test – Focus on high-traffic campaigns and optimize elements that directly impact conversions like headlines and calls-to-action first.
  • Isolate the test – Create a separate campaign or ad group for your test so performance data is kept separate.
  • Run simultaneous rotations – Rotate both versions at the same time so external factors like the day of the week impact both evenly.
  • Let the test run – Leave your test running according to your predetermined sample size and don’t end it early.

KPIs and Evaluating Your A/B Testing

Be sure to track these key PPC metrics for both your A and B variants:

  • Click-through-rate (CTR)
  • Bounce rate
  • Cost per click (CPC)
  • Conversions and conversion rate
  • Cost per acquisition (CPA)
  • Return on ad spend (ROAS)

Evaluate which version meets your ROI goals, not just the highest conversions. If Version B gets 10 more sales but costs 20% more, Version A may still be better for your profits.

Significance testing also determines if differences are statistically significant and not just random chance. PPC management tools or statistical calculators can calculate significance for you.

Filters to Use for A/B Tests

Segmenting your PPC traffic using filters can isolate certain demographics or high-value customers for your split tests. Some filters to consider.

  • Location – Test ad copy that targets certain regions.
  • Language – Test translations to optimize for foreign markets.
  • Device – Test mobile vs desktop layouts and messaging.
  • Audiences – Target previous site visitors or your customer email lists.
  • Day/time – Test weekday vs weekend or non-work hours.
  • Source/medium – Test effectiveness across Google, Bing, social, etc.
