Is your site too slow? Here's how to know in 60 seconds

A quick, jargon-free guide to checking whether your website is slow enough to be costing you customers — and what the numbers actually mean.

Site speed matters for two reasons: humans give up on slow pages, and Google quietly demotes them in search. The good news is that you can check yours in about a minute, no developer required.

The 60-second test

  1. Open pagespeed.web.dev in a new tab.
  2. Paste your homepage URL. Hit analyze.
  3. Wait. Look at the Mobile tab (most of your traffic is mobile).

The three numbers that matter

Ignore the overall score for now. Scroll to Core Web Vitals and look at these three:

  • LCP (Largest Contentful Paint). How long until the biggest thing on screen shows up. Under 2.5s is good. Over 4s is bad.
  • CLS (Cumulative Layout Shift). How much stuff jumps around as the page loads. Under 0.1 is good. Over 0.25 is jarring.
  • INP (Interaction to Next Paint). How long the page takes to respond to a tap. Under 200ms is good.

If your numbers are bad

The usual suspects, in order of how often they cause problems:

  1. Unoptimized images. A 4MB hero photo on a phone over LTE is a real ask.
  2. Too many scripts. Every analytics, chat widget, and tag manager adds weight.
  3. Cheap hosting. Shared hosting that costs $4/mo performs like $4/mo hosting.
  4. Old WordPress theme. Themes from 2018 ship for 2018 browsers.

If you ran the test and the numbers are red, that is fixable. Most performance work pays for itself in a few months in better conversion and rankings. Send us the PageSpeed linkand we'll tell you whether it's a quick fix or a rebuild.
