A mid-market B2B services firm migrated their marketing site off WordPress to Astro static + headless CMS — 4.2 s LCP down to 0.9 s, plugin-vulnerability surface eliminated, marketing team now ships content in plain English. Client name on request.
Marketing site running on a 5-year-old WordPress install with 28 plugins, two security incidents in 18 months, monthly emergency patch cycle, and a marketing team blocked behind developer tickets for every content update. Mobile LCP at 4.2s was tanking organic rankings — Search Console flagged the site as failing Core Web Vitals on 80%+ of crawled URLs.
Crawled the live WP, catalogued every page and template, mapped 1:1 redirects to preserve SEO equity. Astro static rebuild with Sanity headless CMS for editorial. AI prompt-driven editor for the marketing team — they describe a change in plain English; an LLM proposes the structured edit; team approves and ships. DNS cutover with WP frozen as cold backup.
Mobile LCP 0.9s, Lighthouse 100/100/100/100. Organic clicks lifted 38% within 90 days — context: starting from a Core-Web-Vitals-failed baseline, the lift is mostly Google rewarding the LCP fix, not greenfield SEO magic. Search Console flagged URLs cleared within 30 days. Marketing ships homepage modules without engineering. Plugin attack surface eliminated.
"Marketing got their site back. Engineering got their Friday afternoons back."
