Mobile Speed Score Benchmarks by Industry (2026)

Google’s mobile speed score, measured via PageSpeed Insights and Lighthouse, rates your page’s mobile performance on a scale from 0 to 100. A score of 90 or above is considered good, 50 to 89 needs improvement, and below 50 is poor. With mobile traffic accounting for over sixty percent of global web traffic in 2026, your mobile speed score directly reflects the experience of the majority of your visitors.

Why Mobile Speed Demands Special Attention

Mobile devices face constraints that desktop machines do not: slower processors, less memory, variable network conditions, and smaller screens that render differently. A page that scores 95 on desktop might score 50 on mobile because the same JavaScript takes longer to parse and execute on a mobile CPU. This is why Google uses mobile-first indexing and evaluates mobile performance separately from desktop.

Many site owners focus on desktop Lighthouse scores and overlook their mobile performance. This is a critical mistake because Google’s ranking algorithms primarily evaluate the mobile version of your site. A strong desktop score with a weak mobile score provides a false sense of security.

Industry Comparison

E-commerce mobile scores have a median of 52, firmly in the “needs improvement” range. Heavy product image galleries, complex filtering interfaces, and numerous third-party scripts for analytics, personalization, and payment all take a toll on mobile performance. Top performers achieve 78 through aggressive mobile optimization including reduced image quality tiers for mobile, simplified mobile layouts, and deferred script loading.

SaaS sites perform better with a 65 median. Marketing pages tend to be less asset-heavy than e-commerce, and many SaaS companies prioritize performance as part of their technical brand. Leading SaaS sites hit 88 through static generation and minimal client-side JavaScript.

Media and publishing sites struggle the most at 38 median. Ad scripts are the dominant factor, often consuming more processing time than the actual page content. Even well-optimized media sites cap out around 62 due to the inherent overhead of programmatic advertising.

Finance sites lead at 68 median. Text-focused content, minimal third-party dependencies, and dedicated performance engineering teams produce consistently better mobile scores. Top finance sites achieve 90.

Healthcare sites sit at 55 median, with compliance-related scripts, form widgets, and legacy CMS platforms being the primary drag on mobile performance.

Boosting Your Mobile Speed Score

Improving mobile speed scores requires mobile-specific optimization: serve appropriately sized images for mobile viewports, minimize JavaScript execution time by deferring non-critical scripts, reduce DOM complexity for simpler mobile rendering, use font-display strategies that prevent text rendering delays, and audit third-party scripts for mobile impact. Testing on real mid-range devices rather than high-end phones gives a more accurate picture of typical user experience.
