Page loading time is becoming an ever-important factor when it comes to search engine rankings. We use a number of tools to measure site speed performance including Google Page Speed Insights and GTMetrix.
Page Speed Insights (PSI)
Google announced in January 2018 that poor page speed performance would start to negatively affect the worst performing pages . Furthermore, Google updated PSI during November 2018 to change thresholds reducing scores in line with their new performance expectations.
GTMetrix concentrates on a set of scores based on network level analysis and HTTP ARchive meta data, producing a different, yet valuable alternative to Google PSI.
