GTmetrix vs. VWO

GTmetrix is very well suited for small organizations or startups that do not have sufficient technical staff for site optimization. GTmetrix also comes with the free version, which allows users to use their service for free for up to three websites, which is a good option. However, this might not be the best option for a large organization that works in different technical domains and have a good number of technical staff.

Our marketing team does a lot of creative testing around messaging and imagery. VWO is well suited for this type of testing and can yield great results if you define your conversion goals correctly. However, when we have tried to do more substantial/advanced changes through VWO (such as re-positioning content or modifying elements in a form), we have had some challenges and not been able to get the desired tests working correctly.

• Really complete report of performance issues.
• Get reports from PageSpeed and YSlow at same time.
• Gives a score from each separate tool, also displays loading time, page size and total requests very easily.

• VWO has a strong support team willing to help provide answers to questions during the setup process. During setup, we had some questions regarding implementation across a significant number of sites and they were able to ease dev team concerns and provide detailed best practices to streamline integration.
• Some of the initial results of a few of the initial tests raised some questions internally. We setup a call and were able to quickly address the questions and find some opportunities to leverage moving forward.
• I discovered a bug within the UI that lead to some questions internally. I was able to report it and the problem was fixed rather quickly and their team followed up with a thank you for reporting it and to report the issue was now resolved.

• They might consider improving their checking process speed, it often takes a huge time to display the performance report. This is even longer for non-logged-in users.
• Previously two different options of Google's Pagespeeds and Yahoo's lighthouse were shown in the report section, now only combined report is shown. I personally like the two reports from different sources.
• Non-tech savvy persons might not find it so easy to use.

• The heatmaps within A/B tests are overlayed on the live website. Unfortunately, these don't work properly when scrolling down the site.
• I am missing an overview of all my custom conversions. I can only see a list of frequently used goals while setting up an A/B test, which may or may not include all custom conversions.

Visual Website Optimizer is a easy to use and powerful tool for testing web pages. We use it to test lead generation websites to increase the number of people that complete a form. Before we decided to go with Visual Website Optimizer we did research into other options and found Visual Website Optimizer to be one of the best.

It's easy to use fast, data is easy to read and take aways are great too.

Overall VWO is quite good with general user usability, and every person who has had to take up the mantle of using the tool itself has found it manageable. However there is definitely some room for improvement - again, perhaps this is particularly the case because we are running a large number of tests in a number of different languages (and markets, and countries!) which requires a lot of upkeep.

I have not experienced an application error or unplanned outage with VWO.

VWO doesn't appear to slow down our website at all, though some customers with adblockers like UBlock Origin have been known to not see entire pages if VWO is making changes to the page at a macro level (background, font, etc). This is rare though.

I have never had the need to use GTmetrix support. Therefore, there is really no way for me to give a grade here. However, if you are on a paid plan my guess and it is a guess, is that their support is as good as the tool is. There are a lot more features in the paid plans, reporting. monitoring etc. I could see where support could come into play as these features are added to the account

While their online document support is lacking a simple email to their support team will almost always get responded to the next day. It has however taken more than one email to explain the problem to the support team till they understood the problem. The solution I was given also only half fixed the problem the rest I figured out on my own.

Training was good, just limited to the onboarding process. They walked through all of the steps it takes to get started in VWO and each of the modules, along with giving us ideas for starting our first test. I feel like it could be better if there was a guided process within the VWO program to continue to educate you along the way, and a way to turn that off for experienced users.

Overall, the implementation of VWO is straightforward. If you've got a straightforward way of deploying code to all of your test pages, either a good CMS or a TMS, then implementation should be a breeze. There is no tweaking to be done to the code itself, and once deployed it has the flexibility to cope with different VWO modules (tracking, conversion analysis, session analysis) without modification.

Given we are doing the work to improve in Google to a large degree - the Google product is essential. But GTMetrix may use their info as well as other independent stuff to be a little better. I appreciate the way GTMetrix provides the info - cleaner and clearer and thus quicker to address.

VWO is by far the easiest tool to use among all experimentation tools. It is like the experimentation tool for dummies and works as well as the others. A highlight would be the reports on every test because compared to the others, in VWO is way much easier to understand the metrics and the test performance.

The product seems infinitely scalable for our needs (small business) and we've never had any issue with loading VWO-edited elements. I will say, though, that online customers with ad blockers have been known to not see certain VWO elements as their third-party scripts are disabled.

• A great free tool that is does what it is meant to do very well.
• Due to its simplicity and speed it is highly efficient.

Incentivized

• Our clients have seen significant increases in engagement and conversion rates through changes we recommended after using VWO to test our hypotheses.
• Our clients and internal teams have appreciated the level of granular detail available within the platform, as more information leads to more reliable optimization suggestions.
