Likelihood to Recommend 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.
Read full review Optimizely Web Experimentation is appropriate if you have a big budget and your company is mature enough in experimentation to take all the advantage of a such an expensive price model. If you are just starting into AB testing, or not enough budget, I do not recommend Optimizely Web Experimentation, as it becomes quite frustrating to manage usage limits and technical set up to avoid extra charges.

To be able to filter based on a custom metric Tracking scroll depth within the reporting tab A more interactive graph within the reporting tab. Ability to manipulate there vs having to update the whole page Read full review Likelihood to Renew Because it's an incredible and essential tool for my line of work as a conversion optimization specialist. Really couldn't do my job nearly as effectively without it. It's paid for itself many times over and I feel like I'm only beginning to unlock the tools potential.
Read full review Usability It's easy to use fast, data is easy to read and take aways are great too.
Read full review Usability is mostly great. I like the WYSIWYG functionality and adding in real code is simple as well. It's easy to target specific pages or audiences. I've knocked a couple of points off because of how difficult it is to set up URL redirect experiments, confusion around creating pages, and lack of data that can be further analyzed.
Read full review Reliability and Availability I would rate Optimizely Web Experimentation's availability as a 10 out of 10. The software is reliable and does not experience any application errors or unplanned outages.

Read full review Performance I would rate Optimizely Web Experimentation's performance as a 9 out of 10. Pages load quickly, reports are complete in a reasonable time frame, and the software does not slow down any other software or systems that it integrates with. Additionally, the customer service and technical support teams are always available to help with any issues or questions.
Read full review Support Rating 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
Read full review They always are quick to respond, and are so friendly and helpful. They always answer the phone right away. And [they are] always willing to not only help you with your problem, but if you need ideas they have suggestions as well.
Read full review Online Training The tool itself is not very difficult to use so training was not very useful in my opinion. It did not also account for success events more complex than a click (which my company being ecommerce is looking to examine more than a mere click).
Read full review Implementation Rating In retrospect: - I think I should have stressed more demo's / workshopping with the Optimizely team at the start. I felt too confident during demo stages, and when came time to actually start, I was a bit lost. (The answer is likely I should have had them on-hand for our first install.. they offered but I thought I was OK.) - Really getting an understanding / asking them prior to install of how to make it really work for checkout pages / one that uses dynamic content or user interaction to determine what the UI does. Could have saved some time by addressing this at the beginning, as some things we needed to create on our site for Optimizely to "use" as a trigger for the variation test. - Having a number of planned/hoped-for tests already in-hand before working with Optimizely team. Sharing those thoughts with them would likely have started conversations on additional things we needed to do to make them work (rather than figuring that out during the actual builds). Since I had development time available, I could have added more things to the baseline installation since my developers were already "looking under the hood" of the site.
Read full review Alternatives Considered 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.
Read full review Overall, the tools we compared against were great, but we went with Optimizely because it has all the features we needed and has the market leadership that gave us trust we would be successful in our experimentation efforts.
Read full review Scalability While granted, I am not the one making the changes to deploy the software; it seems basically as simple as placing the optimized snippet on your site. If you place it in the header, it should reach across your entire site easily. I do think the test setup can be a bit temperamental at times, and having too many cooks in the kitchen can lead to errors. So, I would caution how many people have the access needed to make actual changes.
