Now let’s get more detailed, with an overview of each of these tools, including their pros and cons.
Google Optimize Review
Google Optimize launched in 2017 and is a major improvement over their previous A/B testing tool which was built into Google Analytics (called Google Content Experiments).
By offering Google offering this for free, it has now become the most commonly used A/B testing tool in the industry, but it has limitations, and is better suited to newer A/B testing users with fewer needs.
As of November 2022, there is some talk of the free version being removed, with only the paid Google Optimize 360 remaining. It that happens, it will definitely cause a huge shift in the market, with no good free or low cost A/B testing tools available at the moment.
Let’s take a look at the notable pros and cons of Google Optimize.
Google Optimize Pricing:
They offer two different plans, offering a free plan and a plan focused on the enterprise market.
- Google Optimize: Free
- Google Optimize 360: You have to contact their sales team for customized pricing
Google Optimize Pros:
- Very good tool for free, and is ideal for businesses who only have basic A/B testing needs.
- Excellent integration with Google Analytics to help improve A/B testing reporting.
- Easy to analyze reports in greater depth using by Google Analytics alongside it.
- Can be upgraded to their premium 360 version to unlock more features.
Google Optimize Cons:
- The usability of it is lacking compared to other tools, particularly the creation of A/B tests.
- Only 5 tests can be run at the same time (unlimited when upgrading to 360 version).
- No ability to use Google Analytics segments (only in 360 version).
- Only 3 success metrics (objectives) can be used (unlimited in 360 version).
- Multi-page testing is not included in the free version (only in 360 version).
- Reporting is not real-time, with 6-8 hour delays in data coming through.
- No ability to copy tests between containers for staging and live, so manual copying is needed.
- No support included, only through forums or paid 3rd party consultants or agencies.
- Upgrading to Google Optimize 360 is very expensive, and really only for enterprise clients.
Rating on G2: 4.1/5 (as of November 2022)
VWO are one of the pioneering A/B testing tools who launched in 2010. They initially started off as a low cost A/B testing tool, but have recently added many excellent features and started to focus more on the enteprise market.
In particular they recently expanded their offerings to include many different plans with additional tools.
They have 6 different plans, but unfortunately pricing is not publically available.
- VWO Testing – the A/B testing tool only which is the lowest cost version
- VWO Full Stack – for doing mobile app and server side testing
- VWO Insights – includes CRO tools for session recordings, survey tools and form analysis
- VWO Personalize – for doing advanced personalization campaigns
- VWO Deploy – lets you deploy winning versions without needing development
- VWO Services – their agency handles all the A/B testing strategy, design and dev for you
Here are the pros and cons of the VWO Testing plan, which is the plan most of their clients choose.
- Intuitive user interface with great A/B test design wizard to help you get better results.
- Includes A/B test duration estimator tool which helps you see if you have enough traffic.
- Includes their very good ‘VWO Plan’ for managing and recording insights from A/B tests.
- Great integration between all the tools on their platform, including visitor recordings and surveys.
- Pricing is not publicly available, and has increased as they moved away from the low cost tool market.
- While they now offer many CRO tools, the different plans and tools are confusing to understand.
Rating on G2: 4.3/5 (as of November 2022)
Convert has evolved from being a great low cost A/B testing tool to one of the most advanced and complete tools available.
They offer 4 plans, with slightly improved features for the more expensive plans, but all with unlimited tests included. Here are the prices as of November 2022.
- Lite: $559 per month (save 30% when paying annually)
- Optimal: $769 per month (save 30% when paying annually)
- Expert: $1,119 per month (save 30% when paying annually)
- Enterprise: You have to contact their sales team for customized pricing
- Is one of the only GDPR compliant A/B testing tools.
- The fastest loading tool for user experience, with no flicker experienced.
- Offers the best support of all tools, including web chat support.
- Their pricing is transparent and publically available, unlike other premium tools.
- Expensive monthly plans, but is cheaper than using VWO or Optimizely (an enterprise tool)
Rating on G2: 4.7/5 (as of November 2022)
I got their free trial extended from 14 days to 30 days for you – you won’t find this elsewhere.
The Verdict: Google Optimize, VWO, or Convert?
To help you make up your mind about which is better for your needs, here are is my expert opinion about these tools:
- Google Optimize is the best for beginners or those with no budget for A/B testing, but has limitations.
- VWO is a great tool for those looking for more A/B testing features than Google Optimize.
- Convert is best for advanced users, with excellent features and the best support options.
Ultimately I suggest you sign up for Google Optimize to see if that meets your needs, and also try a free trial of VWO to see the benefits of their more advanced A/B testing features. If your company can afford to invest in Convert and you want expert features, then use that tool instead.

Other A/B Testing Tools Worth Considering
I reviewed 3 of the most popular A/B testing tools, but there are certainly some other less popular tools you may want to consider. Here are some of the best other ones for you to also consider, each with their own strengths:
- Omniconvert – a multi-purpose tool that also offers personalization, surveys, and website popups.
- A/B Tasty – a good tool that also includes useful options for visitor recordings and heatmaps.
- Optimizely – was the most popular low-cost testing tool, but is now enterprise market only.
- Adobe Target – a very good A/B testing, but is very expensive and for the enterprise market only.
