How to measure whether a website change actually worked
Echo compares each shipped change with the page's own before-state, so you see whether traffic, speed or leads moved, rather than a list of tasks completed.

When you need this
Changes ship but nobody checks afterwards, so you cannot tell which fixes earned their effort or which to repeat.
How the crew does it
Record the before-state
Website Crew
Before a change ships, Echo captures the page's speed, SEO checks, traffic and conversions.
Run the post-launch check
Website Crew
After release, Nova re-crawls the page and Echo reads the same measures over a comparable window.
Report the delta
Website Crew
You see the before and after side by side, with notes on anything else that changed in the same period.
Keep, extend or reverse
You
You decide whether to keep the change, apply the pattern elsewhere, or reverse it.
What waits for you
What to do next with each change: keep it, roll it out further, or reverse it.

Before and after readings for the same page: Core Web Vitals, SEO checks, sessions and conversions.
Limits
Without GA4, impact is estimated from crawl and heuristic data. A before-and-after comparison shows movement, not proof that the change alone caused it.
