This PageSpeed tool is designed to let you check any given webpage and see how well it’s optimized for speed. To provide you with actionable and useful insights, this tool is running on the official Google PageSpeed API. Run the page speed test and use the suggestions and feedback to make your site even faster.
The insights you can expect to get from this tool:
Page speed is important because a fast loading website improves the general user experience, decreases bounce rate and improves conversion rate. For those reasons Google also decided to make page speed part of their ranking algorithm. Back in 2010 Google officially announced page speed as an SEO ranking factor.
A good Google PageSpeed score is considered to be a score of 85 or higher. A page speed score between 85 and 65 gets qualified as Needs work and a score below 65 gets the label Poor returned the Google pages speed insights tool and API. These scores are pretty stable because of the methodology used by Google to calculate these numbers.
The Google PageSpeed score is kind of unique because of the way Google calculates this score. Most tools look at the total load time of a webpage and because of the fluctuations and number of external factors involved this will only give you a time-specific snapshot. When measuring site speed with essential tools like WebPagetest and Pingdom you’ll see a different load time almost every time you perform a test.
On one hand, this is caused by fluctuations like for example time-specific traffic load and on the other hand external factors like user connection speed, browser type and physical location influence these numbers.
The Google PageSpeed tool has removed almost all dynamic variables from the equation and instead focusses on the technical static components of your website. With Server response time being the exception here.
