How quickly your site answers the first knock
When a browser asks for your homepage, there is a pause before anything arrives. We measure that pause once, from one connection, so it is a hint rather than a verdict. If your pages really are slow, visitors on a phone feel it and some give up.
A speed test made for the purpose measures this properly, and it is free.

How to fix it
- Switch on page caching in your website software, or ask your host to.
- Put a free content network in front of the site; it also adds a firewall.
The technical version, for your web person
TTFB. One round trip including any redirect and the whole body, measured from our machine. Under 0.6 s earns the mark, under 1.2 s half.
What the check reads. Wall-clock time for a single requests.get() call — includes DNS lookup, TCP+TLS handshake, every redirect hop, and the full body download, timed client-side. Internally mislabelled 'ttfb'.
This is one of the checks in a YLB Score report. Every report is free, read by a person before it goes out, and written so that you can act on it without us. Ask for yours.
