Can Google PageInsights offer significantly different results depending on where the user is?
Can Google PageInsights offer significantly different results depending on where the `user` is entering the website to be crawled? (have seen that today but wasn`t sure why that was happening - and makes the results rather questionable).
Selected answers from the Dumb SEO Questions G+ community.
Michael Martinez: Page speed is different for every user because of differences in devices, connections, stability in the signal (which can be awful even for 4G smartphones), changes to page content, congestion at Internet Exchange Points (the so-called "fast lanes" you sometimes hear about), problems with the Web server, problems with the receiving device (computer or smartphone), etc. Treat the PageSpeed Insights tool as a metric, not as a representation of reality. It`s affinity for the reality "out there" is extremely loose at best and mostly figurative.
Paul Thompson: PagesSpeed Insights scans form where Google`s server is located, not where you are when you enter the address to be scanned.
Alan Bleiweiss: Neil, it varies because no two connections are alike to the same page. Every process for every individual asset in the page code, can have a different process time with every visit.
Michael Stricker: I much prefer webpagetest.org - a platform that Google now incorporates into their own mobile speed test tool. Why? Because I can specify network (3G majority ‘til 2020), device (Galaxy S7), location (cities US and Intl), Browser (Chrome) and more.
