I have set up my WordPress website recently. The website is talks about some current events around the world. As we know nobody will likes slow website even with great content. So I am searching a good website to test and fix my website speed. While doing online research to find 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 detailed report on the page speed issues as well. But I bit confused, why the all sites gives different results when compared each other. So which website gives better result?
