Your Content Site Ships 847KB of React. Google's Crawler Sees None of It.

Here's the thing most developers don't talk about: Astro ships zero JavaScript by default. Your pages are pure HTML and CSS until you explicitly decide to add something interactive. And that's not a limitation -- that's the whole point. For content-heavy sites, blogs, directories, and marketing pages, this translates directly into faster load times, better Core Web Vitals scores, and honestly a much simpler architecture to maintain long-term. You're not fighting hydration bugs at 11pm. Next.js is genuinely better if you're building a highly interactive web application -- but most sites aren't that.

Content platforms, blogs, documentation sites, and directory platforms are where Astro genuinely shines. We run a 137,000-listing pub directory on Astro -- so this isn't theoretical. Multilingual marketing sites too -- we've deployed in 30 languages without it becoming a nightmare. Programmatic SEO sites generating anywhere from 10,000 to 100,000+ pages from structured data? Pretty straightforward in Astro. Agency portfolios, product marketing sites -- honestly, the pattern is simple. Anywhere content outweighs interactivity, Astro's going to serve you better than the alternatives.

Astro is exceptional for SEO -- and I don't say that lightly after building on half a dozen frameworks. Zero client-side JavaScript means no hydration delay, so your Largest Contentful Paint is instant and you're not getting Cumulative Layout Shift from components loading late. The real kicker is the control you get: built-in content collections, sitemap integration, and complete ownership over your HTML output. No magic, no surprises. Our Astro sites consistently hit Lighthouse scores of 98-100. That's not luck -- that's just what happens when you stop shipping unnecessary JavaScript to the browser.

Yes, and this is where Astro's island architecture earns its reputation. Interactive components -- React, Svelte, Vue, whatever you're comfortable with -- load only where you actually need them, using client directives like client:visible or client:idle. The rest of the page stays static HTML. So you're not paying a performance tax across the entire site just because one section has a search widget or a pricing toggle. You get the interactivity of a single-page app exactly where it's needed, and clean static HTML everywhere else. It's a genuinely smart model.

Marketing sites and blogs typically run GBP 5,000-15,000. Directory platforms with a Supabase backend -- think proper search, filtering, user submissions -- are more like GBP 15,000-40,000. Multilingual content platforms with programmatic SEO built in sit in the GBP 25,000-60,000 range. But here's what actually matters: socialanimal.dev itself is built on Astro. We eat our own cooking. So when we talk about performance, architecture decisions, or build times -- we're not guessing. We can show you exactly how it's built and why we made each call.

Yes, absolutely. We migrate WordPress, Webflow, Gatsby, and Hugo sites to Astro regularly. And it's not the painful process you might be imagining -- we preserve all your existing URLs, SEO metadata, and content structure throughout. Astro's content collections make it pretty straightforward to pull in existing Markdown or CMS content without starting from scratch. Typical migration timeline runs 4-8 weeks depending on site complexity. The sites that benefit most are ones where the old platform was slowing things down -- technically or editorially -- and the team just needed a cleaner foundation to build on.
