What we look for

These pages scored below 90 out of 100 in Google's PageSpeed Insights test, a lab load of each page that rates its loading speed, but not low enough to rate Poor.

Why it matters

Google rates this range as Needs Improvement. The gains are smaller than on poor pages, but visitors on slow phones still feel them.

How to fix

Open each page in PageSpeed Insights (pagespeed.web.dev) and work through its suggestions, starting with those that save the most time.

What it cannot know

The score comes from one lab test per page and can move a few points between runs.

Where you’ll see it

The id is stable, and every surface uses it, so it’s the thing to search for or hand to an agent.

Terminal
When it is one of the five findings under Fix first, raptor crawl prints the id under it.
Check: performance.cwv_score_needs_work
crawl.json and the CSV
The crawl JSON names the finding by this id, and so do the CSV and raptor_query.
"check_id": "performance.cwv_score_needs_work"
The HTML report
This link opens the finding in the report, and each finding shows its id.
crawl.html#finding=performance.cwv_score_needs_work
MCP
raptor_findings with this check_id returns the finding in full, with a fix brief ready to paste into a task. If it didn’t fire, it says why.
