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). It has limitations but is improving. Here are the notable pros and cons of the tool:
- Very good tool for free, much better than their previous offering.
- Excellent integration with Google Analytics improves A/B testing reporting.
- Easy to analyze reports in greater depth using Google Analytics.
- Can be upgraded to their premium 360 version to unlock more features.
- The usability of it is lacking compared to other tools, particulary 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 for targeting (only in 360 version).
- Multi-page testing not included (only in 360 version).
- No support included, only through forums or paid 3rd party consultants or agencies.
Rating on G2Crowd: 4.3/5 (as of May 2020)
There are now several versions of VWO. One is called VWO Testing, and others are VWO insights (including visitor recordings, survey tools and form analysis), and VWO Full Stack (includes mobile app and server side testing). Here are the pros and cons of the VWO Testing plan:
- 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.
- Now includes their great ‘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.
- MVT testing is not available in their lower level package, only in their pro plan.
- Sometimes it’s hard to create tests across pages with complicated URLs.
- Pricing has increased recently as they move away from the low cost tool market.
Rating on G2Crowd: 4.1/5 (as of May 2020)
Convert has evolved from being a great low cost A/B testing tool to one of the most advanced and complete tools available.
- 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.
- Expensive monthly plan, although includes many more visitors than VWO lowest plan.
Rating on G2Crowd: 4.7/5 (as of May 2020)
I have managed to get their free trial extended from 14 days to 30 days – you won’t find this elsewhere.
Which is better? Google Optimize, VWO, or Convert?
To help you make up your mind about which is better for your needs, here are my expert two-cents 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 Convert and you want expert features, then use that tool instead.

Other A/B testing tools worth considering
I have reviewed 3 of the most popular A/B testing tools, but there are certainly some other newer tools. 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 overlays.
- Optimizely – Use to be the most popular low-cost testing tool, but now focused on enterprise market only.
- A/B Tasty – a good tool that also includes useful options for visitor recordings and heatmaps.
