What gets checked
The audit separates ranking signals from test noise.
PageSpeed scores are useful, but they can disagree with what Google and your visitors actually see. nimo starts with field data when it exists, then uses diagnostics to explain the cause.
Real visitor data
nimo checks Chrome field data first, because that is the data behind Google's Core Web Vitals signals.
Lighthouse diagnostics
When field data shows a problem, the audit uses lab diagnostics to explain the likely technical causes.
Prioritized fixes
Instead of a long warning list, nimo tells you which issue to fix first and why it matters.
Core Web Vitals
The metrics are technical. The answer should not be.
nimo translates the metrics into what a visitor experiences and what your team should do next.
LCP
Largest Contentful Paint
How long visitors wait for the main content.
INP
Interaction to Next Paint
Whether taps and clicks feel delayed.
CLS
Cumulative Layout Shift
Whether the page jumps while loading.
TTFB
Time to First Byte
Whether the server responds quickly enough.
Best for
Use it when a generic speed score is not enough.
PageSpeed Insights says you pass, but Search Console says you fail.
A client wants proof that performance actually improved.
Your WordPress or Shopify site slowed down after plugins, apps, or tracking tags.
You need a plain-English explanation before asking a developer to make changes.
Run the audit before you change another plugin setting.
Paste your URL, get the result, and see whether the next fix should be image priority, render-blocking CSS, scripts, server response, or something else.
