Prove a change worked

Write down what you expect, publish, then read the verdict against your own site's normal results and report it.

A change only counts as a win if the page did better than your site normally does over the same weeks. This workflow keeps the before, the expectation and the verdict together, so the result is one you can show.

1. Say what you expect#

Log the prediction before you publish, so you can see afterwards whether it held. To test a change on half of one page type and hold half back, run an experiment.

2. Let it be measured#

Each published change is measured against your own site's normal results and ends with one verdict: working, declined, no change or too early to tell. To hear when a number moves in the meantime, set a metric alert.

3. Read the verdict#

Did it work? lists every change made live and says whether it helped, hurt or is still being measured. The Impact ranking groups the measured changes by the kind of fix.

4. Report it#

The Weekly briefing turns the last seven days into a few cards, and a report deck covers any window you pick, branded, and reopens as it was.
