Is your business's site slow on a phone?

Paste your website's address below to see how your home page loads for customers who open it on a phone.

The free check reads your home page, opens it in a phone-sized browser, loads it again on a throttled Slow 4G connection, and reads its certificate, its links, its tap-to-call phone number, its contact form, its structured data and its mail setup.

It shows its worst findings in full, with how to fix each one yourself, and says how many more of its checks failed. A check it could not run is shown as not measured, never as passed. There is no account and nothing to pay.

Why it matters: Google's web.dev reports that the BBC lost an additional 10% of users for every additional second its site took to load. Source: web.dev, read 2026-10-24

The free check reads your home page; the paid audit measures that page in depth, every finding cited.
