A starting line, not a grade

Record the old site's numbers, with date and settings, first.

Transcript

Before you change a site, write down how the old one performs. Once the redesign replaces it, nobody can measure the old one again. Here's the baseline for AllWeb's current site, measured on the fifth of October.

Speed first. This report comes from a free speed test, run on a simulated mid-range phone over a slow mobile connection. Performance, 76. The largest thing on the page took 4.7 seconds to appear. Layout shift, how much the page jumps while it loads, was 0.052, which is low. Write the settings down with the numbers: the date, the device, the connection and the tool's version. A number without its settings can't be compared with anything later.

Copy each number into one baseline file, with the capture it came from: speed on the phone and on the desktop. The page weight from the audit. And the accessibility scan's three counts. Each of these is one run, and these tests vary from run to run. So in the Test phase you'll run each three times with the same settings, and keep the middle result. It's a starting line, not a grade.

Before you change anything, record the old site's numbers with their date, settings and capture, so the Test phase can compare like with like.
