It's an excellent website speed troubleshooting and testing tool

My overall experience is amazing, I'm using this tool from the beginning. This tool helps me to grow up my speed optimization service and take it to the next level. GT-Metrix saves my time also, I don't need to do research for any critical issues, they have ready all the guidelines about every single problem. I use this tool almost every day, GT-Metrix is now my 1st choice of all speed testing tools.

Pros

The first thing I liked about this tool, is it's super simple to use as well as it's effective. GT-Metrix added a new feature called Speed Visualization which can help me to track every second loading report and the obstacle that blocks the speed index. This tool especially provides two types of score, performance and structure which is very helpful. They don't even just show the website loading speed result. There is a TOP ISSUES tab with a complete guideline for troubleshooting methods. As a developer, I take help from this tool a lot, it's really superb!

Cons

GT-Metrix can't show the exact loading speed or performance in the report. If you scan the site URL for the first time, you'll not get the same result if you scan it for the second time, this is a weird thing. I provide speed optimization services to my clients. After finishing the speed up process, clients check the site performance on GT-Metrix. But the performance they got from their side, not match what I'm getting on my side, so this is another annoying thing about this tool. Scan location of GT-Metrix always shows from Vancouver, Canada, but I'm not in this location. It doesn't matter from where you are scanning or using the tool, it will show Vancouver, Canada location. I think this tool needs to improve these things.

Reasons for Switching to GTmetrix

It is important to me that what other testing tools show reports about the websites. As a developer, I have to take bits of help from all software, not just one.

The best way to test your website response and load time

I use GTmetrix to test all websites we make for us, or for clients. When creating a website for a local tourism company, GTmetrix helped me lower the load time from 8.5 seconds to under 1 second, just by telling me what the bottleneck was and nudging me to the right solution. It is a great tool that I can highly recommend to anyone making websites.

Pros

One click and a few seconds of loading time give me more information about what needs fixing on my website than most other software that I tried. It is an amazing tool that shows you where the issues with the speed of your website are and how to make them go away! I love that it tests against two different metrics, and it has testing options including server location and the ability to measure only until "on load" event.

Cons

I can't say there was anything I disliked about GTmetrix. It would have been great to have even more server locations maybe, but that was never a big issue for me.

Great for helping know website speed!

Pros

I love that within a few seconds GTmetrix can tell me the speed of my website and what things need improved.

Cons

I feel like GTmetrix doesn't really help explain how to fix the issues it identifies.

One of the best performance metrics tools

I have been using GTmetrix for years now and will continue to do so in future. I'm still on the free plan now but will most likely upgrade later on. There's really only 1 alternative that I found to be very good as well, but gives some different views. So I'll be choosing between this and that tool (Dareboost).

Pros

Last year GTmetrix updated their protocol so it's now fully up-to-date with the latest Google metrics. Just by having an account, you have a choice between various different locations to test your website load speed from. GTmetrix gives a lot of different views, metrics and important tips that help you optimise your websites. Not many tools have the possibility to enable video view so you can see exactly how your website is rendered in a certain browser and what the actual loading time is. This is very handy.

Cons

It might be just my websites, but I'm often getting very different results between tests, which can be very frustrating. There's always this doubt whether a website is trully fully optimised when you get A ratings, B ratings and then suddenly an E rating. But again, that's probably not their fault. The limits on the free plan can be pretty frustrating. But they're a business so they obviously need to have limitations on their free plan in order to have more people upgrade and make money.

If you want to increase the performance to position your web page, this is the best tool!

In my particular experience, I use several tools and they are compared with this tool that is the speed reference of load, of YScore, degree of performance, and the most important thing that is that I'm listing in what value each parameter is found Make up my website, from optimization of images to optimization of code and parameters of caching. The truth is I recommend it, it is easy to use and it gives you a lot of value when optimizing your website for a good SEO positioning. Recommended 100%

Pros

I have had very good experience with GTMetrix, and believe me I have used many in order to not only measure the speed of my site, but to correct many aspects that prevent an effective SEO positioning. For me, one of the best tools to measure the speed of loading the website, in addition to this great advantage, also lists the errors you might have within a site and the recommendations to improve or minimize such errors. This tool has given me a lot of value when auditing one of the websites, since it lists the values ​​of each of the parameters that the site has and tells me how long each part of the code of the page takes. So with these values ​​I can optimize my website.

Cons

The truth of all the tools, this seems to me the most complete, because what they lack to others this one has it and it is to be able to compare several websites. The only thing that would add would be other servers, since it only has a location like Canada.
