GTmetrix give you the technical data you need to stay up to speed

We use GTmetrix for two main tasks. It is one of our investigative tools when beginning an SEO audit (or deciding if we even want to take on the client). GTmetrix allows you to quickly get a pretty comprehensive look at the technical health of a website. In just a few minutes you can get a good look to see the data size of a page, get an idea of load time. You can also see if the site is using caching, scaled images, if scripts are minified and/or in-line and the list goes on to address about 25 different parameters.

The other area that we use GTmetrix for is speed optimization. Not only can you see the items mentioned above but you also can look at the Waterfall so you can see the order that assets are loading on the page but also how long each takes. This lets you identify areas that can be improved and find where the biggest improvements can be made with the least effort or cost.

Speaking of cost, all of the above can be accomplished with the free version of GTmetrix.
  • Quickly assess the general technical health of a page or site.
  • Quickly Identify areas that can be improved.
  • I have been using GTmetrix for several years. I have the free account and I honestly cannot think of one thing that I could suggest improvements for. I am not afraid to critique when due. However, in this instance there really is nothing that I can say that I dislike or would like to see different. The interface is easy to understand and use. The information that is produced from scanning a URL is well organized and well presented.
I am not at all averse to the larger SEO platforms like SEMRush or Ahrefs they are great tools and can do virtually do everything GTmetrix can. However, I tend to like tools that are really good at one thing if I am looking to do a specific task.

GTmetrix is superb at what it does. Of all the Website audit tools available GTmetrix is the best at looking at the technical issues a site or page may have. It is built to do this one function and it does it great. Especially considering you can do all this with a free account. If you are looking for Metas description, H tags or other on-site data, this is not the tool. However, if you want to see all your render-blocking Java Scripts if compression is being used or scaled images are correctly sized, this is the tool.

A typical scenario we find ourselves in during speed optimization is to have a tab with GTmetrix open as well as being in the backend of whatever website we are working on. As we make changes to the site we can immediately check using GTmetrix to see how the improvements are helping. This process takes place in real-time and is quite efficient. I can do the same with other tools but they tend to look at other areas of the site at the same time and that makes the process slower.

We use GTmetrix to ensure a fast load time of websites for clients. Many have beautiful sites, but they now know their sites load slowly. GTmetrix is great to know where the site is lagging and how to improve the site to load quickly. Some areas are more important than others and the breakdown from the report is perfect to prioritize the areas for improvement.
  • Reporting
  • Recommendations
  • A few more test locations
  • Save more runs when logged in
Showing page speed results to others is great! The breakdown is outstanding. It has an overall PageSpeed, YSlow, Waterfall (super useful), and more. It might not have the most technical details, but for a free tool, it does a perfect job for everyone. If someone wants to dig into the details, they can easily click on one of the tabs and dig in.

An excellent tool for website performance reports

We use GTmetrix on a regular basis throughout the organization, since it helps us get insights from website performance issues and what we can do to improve that.

It gathers data from PageSpeed, YSlow and Waterfall (like devtools), besides offering some paid features like timings, video and history.
  • 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.
  • The user interface is a little bit confusing.
  • You can't choose a different test server (since we're from Brazil, it doesn't reflect exactly what most of our users are experiencing).
  • There's a wait time (queue) in case there are other users using the platform at the same time.
GTmetrix is an excellent tool if you need insights and a complete report on your website's performance and what you can do about it. Google PageSpeed, for instance, offers more features in order to get better results.

Although the user interface is inferior, I rather use GTmetrix than PageSpeed or YSlow separately.
