Symptoms, then evidence
Is my website slow? Start with a lab snapshot you can act on
“Slow” shows up as bounce spikes, abandoned checkouts, and vague complaints from sales. This check does not guess—it measures how your page behaves in a controlled mobile-first lab run so you can separate real bottlenecks from anecdotes.

What we measure when you ask if your site is slow
Google PageSpeed Insights (Lighthouse-style) scores how long it takes for meaningful content to appear, how quickly the page responds to input, and whether the layout jumps while loading—signals that map closely to what people describe as “sluggish.”
- Time-to-meaningful-content patterns in a throttled lab environment.
- Input delay signals that make taps and clicks feel unresponsive.
- Cumulative layout shift: content that moves after it appears.
- A prioritized list of opportunities often tied to images, scripts, and third parties.
Why “feels slow” needs a shared definition
Teams argue less when everyone looks at the same numbers. A lab snapshot gives marketing, design, and engineering a neutral baseline before you debate redesigns or new hosting.
Lab data is not the same as what every visitor experiences on every network—but it is repeatable. Use it to verify fixes after releases and to compare candidates (old template vs new, with vs without a tag).

Slow website FAQ
If the lab score is good, can my site still feel slow?
Yes. Real users on weak devices or congested networks may have a worse experience. Treat a strong lab score as a green light to look elsewhere (hosting region, database latency, or server-side rendering), not as proof that no one waits.
Does this replace Real User Monitoring?
No. RUM tells you what happened in the wild; the lab tells you what is likely wrong on the page you tested. The two complement each other.
Why mobile-first?
Most consumer traffic is mobile, and mobile profiles are stricter. The full audit on the homepage runs both mobile and desktop strategies so you can compare.
What do I do after I see a low score?
Start with the top few diagnostics that affect many pages (shared scripts, hero images, font loading). Re-run after each change to confirm impact.
