26 A/B Testing Tools To Improve Your Conversions in 2018
Rate this post

So, you have decided to use A/B testing to optimise conversions on your website? But how do you know which tool to choose? This list of 26 A/B testing tools will help you pick the best solution for your company.

Firstly, you should ask yourself two important questions:

  • How do I decide which is the best A/B testing tool for my company?
  • Will the tool help me to optimise my conversion rate?

There are now more than 20 A/B testing tools on the market, not to mention those that offer testing as part of a wider service. We have taken the market leaders, including AB Tasty, Kameleoon, Optimizely, and Google Optimize, and analysed them according to the most important criteria.

A/B Testing Tools analysis
Full A/B Testing Tools Table Displayed Below

Four years ago, the A/B testing market was divided between two options: Optimizely and VWO. Since then, the number of testing tools has increased rapidly. AB Tasty arrived, with a set of advanced analytics, and in 2017 Google launched its own optimisation software, Google Optimize. In 2018 there are no less than 26 software solutions competing for your attention. 

To expand their market share, some publishers – such as AB Tasty and VWO – have begun to offer a vast range of analytics (heatmaps, mini-questionnaires, recording sessions). Others – such as Convertize – have simplified AB Testing by focusing on the features that bring results to marketers.

Our analysis will focus on the A/B testing capabilities of each tool. Extras, such as heatmaps and recording sessions) will be dealt with another time.

Which criteria are important for an A/B Testing Tool?

The first questions most marketers ask when choosing a new tool concern the price (setup fee and monthly subscription) and the usability (both client-side and server-side). But there are other factors to consider, too.

Our table compares 6 criteria, including ‘Must-have’ and ‘Luxury’ features.

1. “Must-have”: These are the essential features required to perform A/B tests :

2. “Luxury” or “Professional”: These are the options that make AB testing easy (Luxury) or allow for high-traffic sites (Professional):

  • Automated mode – Luxury
  • Tactics library – Luxury
  • Multivariate Testing (MVT) – Professional

In addition to this, it is important that you consider your company’s needs. The tool you choose should reflect the size of your business, your previous experience with other software and your technical resources (budget, the size of your team, etc.)

A/B Testing Tools – Definitions

Client Side

“Client-side” means the tool is applied by the visitor’s browser (for example, Internet Explorer or Firefox). This is done by ‘tagging’ the webpage’s HTML with several lines of Javascript. When the page is loaded, the Javascript makes calls to a back-office system (such as Google’s Analytics servers), which then notifies the browser of which page content should be downloaded and displayed. The back-office system also keeps score of conversions.

Server Side:

“Server-side” means the tool runs on the server. The page is compiled by the server, and is presented to the browser in its finished form. In the same way that some PC software is only available for Windows or for Macs, some server-side software is only available for particular server technologies (such as PHP).

A/B/n Testing and Split Testing

In an A/B test, your visitor sees Version A of a page or Version B of it. (Note, a test with three page versions would be called an A/B/C test. “A/B/n” is often used as shorthand for a test that has n different page versions.

Multivariable Testing

“Multivariate” or “Multivariable” (MVT) tests are simply ones in which you carry out A/B tests (or A/B/n ones) on several independent page elements simultaneously. There are many different ways of carrying out multivariate (MVT) tests: You can show every single possible combination of page elements (“full factorial”) or only a fraction of them. There are many types of “fractional factorial” test, and they all have complicated-sounding names (for example, “Taguchi”). You can also choose to display losing combinations less frequently.

Autopilot 

Some A/B Testing tools allocate traffic evenly between variation A and B. This could potentially mean directing half of a website’s traffic to a less-optimal version (which can cost large companies vast amounts of money). With an “autopilot” feature, traffic is directed in larger numbers to the best-performing variation during the test. 

Multi-Armed Bandit

The “Multi-Armed Bandit” solution is a form of Autopilot in which traffic is directed to better-performing pages according to more complex rules.

Page-Editing

Some of the software tools have in-built platforms for creating and editing webpages — a bit like having their own WordPress interface. They can be useful if the thought of involving your company’s web development team gives you the shudders.

Tactics Library

Knowing which elements to test is a significant advantage when A/B testing. Tools such as Convertize provide a catalogue of proven tactics to structure your testing.
