An explanation of the Google Page Experience update
By introducing the following three metrics, Google hopes to decrease common frustrations users have whilst interacting with web pages:
- What speed does the page load at?
- How soon is the page interactive?
- How stable is the page?
By prioritising the webpages that positively satisfy these metrics, Google hopes to recommend those which are easy to use and well-maintained first.
If you want to really get to grips with the upcoming changes, here’s our breakdown of the technical details…
These are the core web vitals that will impact your site’s traffic:
- Largest Contentful Paint (LCP)
This is the main metric for page load speed. It measures how long users have to wait before large blocks of content load such as images, videos and chunks of text. Page content that takes more than 4 seconds to load will rank poorly, to improve your LCP measure, consider doing the following:
- Scale down image sizes so they load faster
- Use a size loading optimizer plugin
- Boost server speed
- Cumulative Layout Shift (CLS)
We’ve all been there, opened a page and tried to click on something before it’s fully loaded, and then by the time it does load, a shift occurs that changes the location of where we clicked. It’s a real pain and this metric measures just that. Unexpected element shifts can cause unwanted interactions, to avoid this make sure elements on your page do not suddenly change in size between the first and final loading.
This one measures how soon you can interact with elements on a page, or how quickly these interactive elements respond to user action. A good measure for this is 100 milliseconds, and anything longer than 300 milliseconds is, well, too long. You can improve on this by using a good programmer to test, audit and optimise the code.
