Astro · Performance

From Lighthouse 40 to 95+. In 2 to 3 weeks.

Your site loads too slowly — and it costs you rankings and conversion. We audit Astro, Next.js, Nuxt and WordPress sites, fix the real bottlenecks and ship a measurable improvement: typically 95+ on mobile Lighthouse, LCP under 1.5 seconds. With a before/after PDF report.

Performance sprint from €1,890 · complex apps individual · often paired with a maintenance retainer.

01 · Background

Why performance is SEO today.

Since 2021 Core Web Vitals (LCP, INP, CLS) have been an official Google ranking factor. Sites that miss the bar lose visibility — and conversions. Every second of load time above 2 seconds costs measurable revenue: Amazon quantified it at 1 % per 100 ms, Akamai at 7 % conversion drop per second.

  • LCP under 1.5 s is achievable — we ship it routinely even on slow mobile connections.
  • INP under 200 ms — interactive pages without JavaScript jank.
  • CLS under 0.1 — no layout jumps as the user scrolls.
  • Image optimisation with AVIF/WebP and a proper srcset strategy.
02 · Deliverables

What's in the performance package.

Lighthouse audit

Detailed audit of all templates and the top 10 URLs. Mobile + desktop.

Bundle analysis

We measure what JavaScript is actually shipped — and reduce it.

Image optimisation

AVIF/WebP conversion, correct sizes, lazy-loading, LCP-image prioritisation.

Font strategy

Self-hosting, font-display, preload for critical fonts, subset for unused glyphs.

Critical CSS inlining

Above-the-fold CSS inline, the rest deferred. Render-blocking eliminated.

Server Islands & streaming

Slow components move into Server Islands — the rest streams instantly.

CDN & edge deploy

Cache headers, edge cache, static pre-rendering wherever possible.

Real-user monitoring

Setup of CrUX tracking so you continuously see what real users experience.

Before/after report

PDF with Lighthouse comparison, CrUX data and a prioritised roadmap for next iterations.

04 · FAQ

Performance questions.

Does this work for non-Astro sites? +

Yes — we audit Next.js, Nuxt, Gatsby and WordPress sites too. For WordPress we often recommend a direct Astro migration.

How much will my Lighthouse score improve? +

Going from a typical 40–60 → 90–100 is normal. We give a pre-estimate after the audit.

What does a performance sprint cost? +

From €1,890 for small sites · €3,490 for mid-size sites · individual for complex apps.

How long do the gains last? +

Structurally permanent — but new content / plugins can degrade performance again. Our maintenance retainer keeps it tracked.

Performance is ranking

Astro isn't faster. It plays a different game.

Real data from the Chrome UX Report: Astro sites pass Core Web Vitals 66 % of the time. WordPress: 48 %. Next.js: 30 %. That's not tuning — it's architecture. And Google notices. Better vitals = higher ranking = more customers who find you before they find your competitor.
