Speed optimization for a vibe-coded site is a flat pass from $1,200, done in 3 to 5 days. AI builders ship heavy pages — uncompressed images, render-blocking scripts, bloated CSS — that fail Core Web Vitals and quietly cost you customers. We make yours fast: quicker loads, green Core Web Vitals, and a Lighthouse score you can screenshot.
Why vibe-coded sites are slow
AI builds for looks, not weight. It inlines everything, drops in a four-megabyte hero image at full size, loads three fonts and a CSS framework you use two classes from, and never lazy-loads a thing. On the builder’s laptop it feels instant. On a customer’s phone on a normal connection it crawls, and that’s the device most of your traffic is on. Google measures exactly this through Core Web Vitals, and so do your visitors — a large share abandon a page that takes more than about three seconds to load.
What the speed pass covers
- Images: compressed, resized to what the layout actually needs, converted to next-gen formats (WebP/AVIF), and lazy-loaded below the fold.
- Code: JavaScript and CSS minified and deferred, unused framework weight stripped out, critical CSS inlined so the page paints immediately.
- Fonts: subset, preloaded, and set to show text instantly instead of blocking the render.
- Delivery: caching headers, CDN-ready assets, and render-blocking requests removed from the critical path.
- Core Web Vitals: LCP, CLS, and INP brought into the green on both mobile and desktop — the three numbers Google actually scores.
- Proof: a before/after Lighthouse and PageSpeed report, and every change committed to your GitHub so you own it.
Why speed is money, not vanity
Fast sites make more of their traffic. Faster pages consistently convert better than slow ones, and Core Web Vitals are a confirmed Google ranking signal, so a speed pass is the rare fix that helps rankings and sales at the same time. It also compounds: every ad click and every SEO visitor you’re already paying for is worth more when the page they land on doesn’t make them wait. We wrote about how this ties into search in whether AI-built sites rank on Google.
What we won’t do
Game a Lighthouse number without a real-world gain, hide content to fake a fast paint, or strip features your site needs to hit a vanity score. The goal is a site that’s genuinely faster for the people loading it on real phones, measured on the pages that actually matter.
Common questions
How much does website speed optimization cost?
Our flat speed pass starts at $1,200 and takes 3 to 5 days, covering images, code, fonts, caching, and Core Web Vitals, with a before/after report at the end. A large or complex site runs higher, but you get one flat number up front — no hourly billing.
How much faster will my site actually get?
It depends on where you start, and vibe-coded sites usually start rough. A typical AI-built site goes from red Core Web Vitals to green, often from a Lighthouse score in the 40s to the 90s on mobile. We measure before and after with Lighthouse and PageSpeed Insights and show you both numbers, so the gain is real and documented, not a claim.
What are Core Web Vitals?
Three metrics Google uses to score real-world experience: Largest Contentful Paint (how fast the main content appears), Cumulative Layout Shift (how much the page jumps around as it loads), and Interaction to Next Paint (how quickly it responds when tapped). Passing all three is what “green Core Web Vitals” means, and it’s both a ranking factor and a conversion factor.
Does site speed affect SEO?
Yes, two ways. Core Web Vitals are a direct Google ranking signal, and speed also drives the engagement metrics — bounce, time on page, pages per visit — that indirectly shape rankings. A slow site is fighting search with one hand tied behind its back.
Can you speed up a WordPress, Wix, or Framer site?
WordPress, yes, and it’s where the biggest gains usually live — images, plugins, caching, and theme bloat are all fixable. Hand-coded and static sites, absolutely. Locked platforms like Wix or Squarespace we can improve within what the platform allows, but the ceiling is theirs, not ours, and we’ll tell you honestly what’s reachable before you pay. If the site is broken as well as slow, that’s a rescue job, and ongoing care lives in a care plan.
