Astro Development Agency for Content-Heavy Sites

Astro development is the practice of building content-heavy websites -- blogs, directories, marketing sites, documentation -- using Astro's island architecture instead of a full JavaScript framework. It's for growth leads and technical founders whose Next.js or WordPress site ships hundreds of kilobytes of React or PHP-rendered bloat before Google's crawler reaches the H1 tag, and who need Core Web Vitals and rankings to recover. Pages compile to static HTML at build time, interactive components hydrate only where explicitly opted in, and design tokens flow through vanilla CSS custom properties instead of a runtime theme provider. A typical engagement with an Astro development agency runs an audit (about a week), component and token setup (one to two weeks), then build and content migration (two to four weeks), landing on edge infrastructure with Lighthouse CI gating every merge. Marketing sites and blogs run GBP 5,000-15,000; directory platforms with a Supabase backend sit in the GBP 15,000-40,000 range; multilingual programmatic SEO platforms run GBP 25,000-60,000. We've done this rebuild ourselves -- bdManagedIT moved off WordPress onto Astro and Sanity and now scores 95+ on PageSpeed with fully static service, industry, and compliance pages. Our own site runs on Astro too, at 1,797 English pages across 11 languages with React islands only where needed. The output is a site that reads like a document to both users and Googlebot, with no hydration delay and no layout shift from client-side style recalculation.
