GTmetrix

We are using GTmetrix in our organization for many years. It works really great. It gives a wide analysis of the site performance using many advanced options and many vital options, so we may use it to know where we are lacking the site performance and with the help of their nice documentation and detailed report, it is an easy process to resolve the issues and improve the site performance. It also helps in the SEO in an indirect manner.

We use GTmetrix to monitor the performance of our websites in an intensive way. Nowadays performance is a must to every website since users don't want to wait and if they wait one or two times they go to the competitors.

The product provides solid information about page load speeds, addressing any issues that slow the process. They also provide detailed information on performance such as first paint as well as structure and waterfall. Great tool for seeing how changes to a webpage impact various important elements. I use it often to check new pages, as well as a handful of important transactional pages that needs to be quick and clean to ensure more sales.

I use GTmetrix along with my team members to monitor our multiple websites. It helps us to determine any issues with our website. It provides us the authentic report on the current state of any site and provides applicable suggestions which in turn make the websites more convenient to the user of our services throughout the world.

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.

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.

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.
