Performance
How fast your page arrives, and how heavy it is on a phone.
Why it matters
Most of your visitors are on mobile data. Every extra second of loading loses customers, and Google ranks slow pages lower. We measure what your server sends and, with Google PageSpeed, how real phones experience it.
What good looks like
- The main content shows in under 2.5 seconds
