What's a good page load time?

Aim for LCP under 2.5 seconds on 75% of real-user sessions. Total time-to-interactive under 3.5 seconds on 4G.

For almost any site with visitors outside a single region — yes. It's the single highest-leverage change for TTFB and LCP.

Will lazy loading break SEO?

No, as long as your LCP element is not lazy-loaded and content above the fold is present in the initial HTML.

How to Improve Website Speed

GAP Team · Jul 16, 2026 · 8 min read

Speed fixes fall into three tiers: cheap-and-huge, moderate-effort, and rewrites. Work in that order — most sites unlock a full second of LCP in the first tier alone.

Tier 1 — cheap and huge

Compress and resize images. Serve WebP/AVIF at the actual displayed size.
Add width and height to every image so layout doesn't shift.
Set a CDN in front of your site (Cloudflare, Fastly, or your host's built-in option).
Preload the LCP image and your primary web font.

Tier 2 — moderate effort

Defer or lazy-load below-the-fold JS bundles.
Split routes so first paint doesn't ship the entire app.
Cache HTML at the edge for anonymous visitors.
Move third-party tags to async and audit each one.

Tier 3 — rewrites

SSR or SSG for pages that still can't hit good LCP. Replace heavy client-side frameworks on marketing pages with static HTML.

Measure with the right tool

Use field data (CrUX / Search Console) for scoring and lab data (Lighthouse) for debugging. See Google Lighthouse Explained.
