What the score measures
PageSpeed Insights is a free Google tool that loads your page on a simulated mid-range phone with a slower connection and scores the result from 0 to 100. The score combines several measurements of how quickly the page shows its content and how soon it responds to a tap.
Why mobile and desktop differ
The same page often scores 95 on desktop and 45 on mobile. Phones have slower processors and connections, so heavy scripts and large images hurt far more. Since most local searches happen on phones, a good desktop score is not much comfort.
What usually pulls the score down
- Oversized images uploaded straight from a camera or phone.
- Page builders and multipurpose themes that load far more code than the page uses.
- Sliders and background video at the top of the page.
- Many third-party scripts: chat widgets, pop-ups, several tracking tags.
- Web fonts loaded in many weights.
- Cheap or overloaded hosting that is slow to respond.
Is 100 necessary?
No. The difference between 92 and 100 is invisible to a visitor. The difference between 35 and 90 is not. Aim for the green band and spend the rest of the effort on content.
