Why we migrate WordPress sites to Astro (and how to not lose rankings)
WordPress powers a huge chunk of the web, but a decade of plugins, themes, and database calls adds up. For content-heavy and marketing sites, a static-first rebuild on Astro is often the single biggest performance and SEO win available.
Why the move
- Speed: a static Astro site has no database on every request and no plugin bloat. Pages that took 4 seconds load in under one.
- Security: no PHP, no plugin attack surface, nothing to patch.
- Cost: static pages serve from a CDN for near zero.
- SEO: Core Web Vitals go green, and that’s a ranking signal.
Why people don’t (and the fix)
The fear is losing rankings. The fix is treating a migration as a technical SEO project with a new front end:
- Content extraction: pull every post, category, author, and image into clean Markdown.
- 1:1 redirects: map every old URL so no link equity leaks.
- Schema: preserve or upgrade your JSON-LD (Article, Breadcrumb, Organization).
- Sitemap: ship a clean sitemap so new URLs get discovered fast.
- Cutover: staged DNS switch with monitoring, not a big-bang gamble.
The result
Get the redirects, schema, and Core Web Vitals right and a migration is a positive SEO event, not a risk. In practice, we’ve seen sites go from a 4.1s LCP to 0.9s and more than double organic traffic within six months.
