Where you fall

Underperforming

Over 5s mobile

Page is heavy with third-party scripts (analytics, chat widgets, fonts), unoptimized images, or render-blocking JavaScript. Each fix typically cuts 0.3 to 1.0 second.

Typical range

1.5s to 3.5s mobile

Healthy load time. Standard Next.js / Vercel hosted marketing pages sit here with minimal optimization. SEO floor is met.

Outperforming

Under 1.5s mobile

Static-first architecture, image optimization, no third-party JS. Conversion benefits are real but diminishing under 2 seconds.

What drives this metric (in order)

  1. Third-party JavaScript (the biggest performance cost)
  2. Image format and size (next-gen formats, proper sizing)
  3. Font loading strategy (system fonts > preloaded > async)
  4. Render-blocking resources
  5. Hosting and CDN configuration

Questions founders ask

Does page speed affect SEO?

Yes, marginally. Google's Core Web Vitals (LCP, INP, CLS) factor into rankings. Most indie SaaS see SEO impact at the margins; the bigger reason to optimize is direct conversion rate.

Is Next.js fast enough out of the box?

Yes for marketing pages. Static generation (or App Router server components) on Vercel sits under 2s mobile time-to-interactive without any optimization work. The performance debt accumulates from added third-party scripts and unoptimized images.

Should I remove my analytics tools to improve speed?

No. PostHog, GA4, and similar tools cost 100 to 300ms on first paint, which is acceptable. Remove only the duplicated tracking (most sites have 3 to 5 redundant analytics tools loaded simultaneously).
