What Is a Good Website Speed Score?
A good PageSpeed score isn't 100. Here are the real benchmarks for mobile and desktop, what they mean, and how to know if your site is actually slow.
Table of contents
PageSpeed Insights gives every website a score from 0 to 100. But what counts as "good" depends on whether you're looking at mobile or desktop, what kind of site you run, and which version of Lighthouse generated the score.
This article cuts through the noise: here are the real benchmarks, the realistic targets, and what your score actually means in 2026.
The official PageSpeed score ranges
Google groups every score into one of three buckets:
| Score | Label | Color |
|---|---|---|
| 90–100 | Good | Green |
| 50–89 | Needs improvement | Orange |
| 0–49 | Poor | Red |
A score in the green zone (90+) means your site is among the fastest 10% of sites Lighthouse measures. A score under 50 means real users are almost certainly noticing slowness.
Realistic targets for production sites
Hitting 100 on a real production site is rare. Sites with analytics, embedded videos, third-party widgets, and a CMS will struggle to break 90 on mobile even when well-optimized.
Here's what most well-built sites actually score:
- Static marketing sites: 95–100 mobile, 99–100 desktop
- Modern SaaS landing pages: 85–95 mobile, 95–100 desktop
- WordPress with a fast theme: 70–85 mobile, 90–98 desktop
- News and media sites: 50–75 mobile, 80–95 desktop
- E-commerce (Shopify, etc.): 40–70 mobile, 75–90 desktop
- Heavy web apps (dashboards, editors): 30–60 mobile, 60–85 desktop
If you're hitting the upper end of your category, you're doing well. Don't chase 100 at the expense of features your users need.
Why mobile scores are always lower
Lighthouse runs mobile audits using a deliberately slow simulated environment:
- Network: Slow 4G (1.6 Mbps download, 750ms RTT)
- CPU: 4× slowdown applied to your processor
- Device: Mid-tier Motorola Moto G4
This isn't a bug — it's the median user. If your site only works well on a fast laptop on fiber, it doesn't work well for half your visitors.
This is why mobile scores are typically 20–40 points lower than desktop scores. Always optimize for the mobile number. Read more in our mobile speed vs desktop speed article.
What goes into the score
The performance score is a weighted average of six Core Web Vitals and related metrics:
| Metric | Weight |
|---|---|
| Largest Contentful Paint (LCP) | 25% |
| Total Blocking Time (TBT) | 30% |
| Cumulative Layout Shift (CLS) | 25% |
| First Contentful Paint (FCP) | 10% |
| Speed Index (SI) | 10% |
INP (Interaction to Next Paint) is measured separately as a Core Web Vital but doesn't directly factor into the Lighthouse performance score.
How to know if your site is actually slow
The PageSpeed score is a simulated number. Real users are what matter. If you're worried about real-world performance, look at:
- Field data from PageSpeed Insights — scroll down on the report to see actual Chrome User Experience Report (CrUX) data from real visitors.
- Bounce rate above 60% — a strong signal that visitors are giving up before the page finishes loading.
- Mobile sessions noticeably shorter than desktop — often means mobile performance is poor.
If your lab score is 90+ but field data shows poor LCP or INP, that's a clue your testing environment doesn't match real users.
Quick wins to push your score up
If you're sitting at 60–80 on mobile, these four changes usually get you into the green:
- Convert images to modern formats (WebP or AVIF). See how images affect website speed.
- Defer non-critical JavaScript. Read how JavaScript slows down websites.
- Add
loading="lazy"to below-the-fold images. - Preload your hero image so LCP is fast.

The bottom line
A "good" score is 90+ on desktop and 80+ on mobile. A realistic target for most sites is 70–85 on mobile. If you're below 50, you have a real problem worth fixing — both for SEO and for the actual humans visiting your site.
Frequently Asked Questions
Is a PageSpeed score of 80 good?+
Yes — 80+ is considered good and is the realistic target for most production websites. Anything above 90 is excellent, and 100 is rarely achievable on real-world content sites without sacrificing functionality.
Why is my mobile score so much lower than desktop?+
Lighthouse simulates a mid-range Android device on a slow 4G connection. Mobile scores are typically 20–40 points lower than desktop. This is intentional — Google wants you to optimize for the slowest realistic conditions.
Does a higher PageSpeed score mean better Google rankings?+
Speed is a ranking signal, but it isn't the only one. Sites with excellent content can rank fine with a 50 mobile score. However, sites with poor Core Web Vitals (LCP, CLS, INP) get noticeably ranked lower.
