Hi Guys, I was checking my website's page load time through Google Analytics tool and found website Avg. Page Load time - 30 Secs. Now when i open my website, it takes only 1 to 2 secs to open in my browser (Incognito mode). Then i have checked it through SEOprofiler tool and it says - fastest page is 563 ms (0.56 sec) and Slowest 919 ms (0.92 sec). Also i have checked website in GTMetrix tool and it says - 5.6 sec (Server - Canada, Browser - Chrome). Now, my question is which data is true? I think all, but how can we validate that analytics is showing right figure and how it is calculating it? Which tool you recommend is best to calculate correct page load time and speed?
Keep in mind that there is a difference between server response time and page load time. Many of the tools you mentioned (like GTMetrix) provide waterfall representations so you can identify what's causing a delay in fulling loading the page (my guess is there's some third-party scripts that are causing the delay). My recommended "starter" tool is the "Test My Site" tool on thinkwithgoogle(dot)com - why not go to the source, right?
