A Closer Look at Google PageSpeed
There was a time when core web vitals were not very relevant in the world of search engine optimization, and this was largely because the Google algorithm was mostly focused on content instead of other ranking factors such as page loading times. Core web vitals are all about metrics; as such, there are numerous tools that you can use to measure certain ranking factors, and each of them is bound to give you different results.
It stands to reason the Google's own PageSpeed Insights should be the golden standard for measuring page loading times, but not all SEO professionals agree in this regard. When you have a website that loads in less than three seconds on an average desktop, you can expect to get scores higher than 95% on popular measurement tools such as GTMetrix, which is recommended by many SEO agencies. The problem is that this quick loading experience will not always be detected by PageSpeed Insights, and this can lead many to believe that Google will not assign a favorable ranking score.
Quite a few SEO practitioners have noticed that the PageSpeed Insights tool does not provide accurate measurements, particularly when it comes to mobile websites. This complaint is relatively new; when Google first launched PageSpeed Insight, users reported that the results matched not only GTMetrix but also their own stopwatch measurements. Unfortunately, this stopped being the case in the months following the declarations of the novel coronavirus pandemic.
One page loading speed aspect that many SEO professionals have noticed is that using the right content delivery network can make a big difference in terms of passing the PageSpeed Insights test with flying colors. Nitro CDN is the solution most often mentioned; it almost feels as if Google has forged a partnership with Nitro, but this is highly unlikely. The bottom line of a solid CDN is that it Google will detect its use; therefore, you can count on a more favorable core web vitals consideration.
In the end, you may not even need to worry about page loading speed that much to begin with. If the Google algorithm sees that your website is properly hosted on a speedy data center, chances are that this will be a more influential ranking factor that the actual loading time.
