I have set up my WordPress website recently. The website is talking about some current events around the world. As we know nobody will like slow websites even with great content. So I am searching for a good website to test and fix my website speed. While doing online research to find the best speed testing sites, I found, GTmetrix.com, Pingdom.com, and Google page speed insights in the top list. I got to know that all sites will provide a detailed report on the page speed issues as well. But I bit confused as, why all sites give different results when compared to each other. So which website gives better results?
