Website Speed Audit

How fast does your site actually load?

One clear score for desktop and mobile - no jargon, no dashboard to learn. Just how fast your site is and what to fix first.

Audit my site's speed

What your score means

90-100

Fast

Visitors rarely notice load time. Good territory for conversions and rankings alike.

50-89

Needs work

Load time is starting to cost you visitors, especially on mobile connections.

0-49

Slow

A meaningful share of visitors are leaving before the page finishes loading.

Why speed is worth checking

Every extra second costs visitors

The longer a page takes to become usable, the more people leave before it does - this compounds on mobile networks.

Speed affects conversions directly

Faster pages consistently see higher checkout, signup, and form-completion rates than slower ones on comparable traffic.

Google factors it into ranking

Page speed is one of many signals search engines use - not the only one, but a real one that's fully within your control.

Desktop

Full network & CPU profile

Mobile

375px, throttled conditions

FAQ

Frequently asked questions

"Loads okay" on your own fast connection can still be genuinely slow for a visitor on a mobile network across the country. This audit measures actual load timing under controlled conditions, not a subjective glance.

Both - the audit runs each automatically. Most sites see meaningfully more traffic on mobile, and mobile scores are frequently worse than desktop, so checking only one gives an incomplete picture.

Usually images: oversized, uncompressed, or loading before they're needed. After that, unnecessary third-party scripts (chat widgets, analytics, ad tags) are the next most common culprit. The full report prioritizes issues for you rather than leaving you to guess.

They're related but not identical. This speed audit gives you one clear, plain-language number to act on quickly. For the full technical breakdown - LCP, CLS, TBT, Speed Index individually - see the Performance Audit.
