SEO for Astro websites
The perfect foundation for content sites: static generation, zero JS by default, perfect Core Web Vitals. SEO on Astro works out of the box — the optimizer's job is to not break it and scale it. Astro is our top choice for blogs, corporate sites, and media projects. Of all modern frameworks, Astro delivers the best Core Web Vitals and indexation from day one.
SEO services for SEO for Astro websites
SSG and prerendering setup
astro.config configuration — separate static/SSR strategies for different site sections.
Islands and interactivity without SEO harm
client:visible / client:idle for heavy components so first paint isn't blocked.
Dynamic meta tags via @astrojs/seo
Each page gets unique title/description/og — no duplicates.
Schema.org via JSON-LD
Auto-generated Article, BreadcrumbList, FAQPage markup from content frontmatter.
Sitemap and robots.txt
@astrojs/sitemap with proper priorities and changefreq. Separate maps for large projects.
Hreflang for multilingual
Correct markup via @astrojs/i18n, x-default, canonical for each language version.
What breaks SEO on this stack
Hydration mismatch breaks indexation
When client:load used instead of client:visible — Google sees a 'jumping' DOM and penalizes the page for CLS.
View Transitions without proper setup
Astro 4+ introduced View Transitions — without proper client-router config, analytics breaks.
Content Collections without schema
Markdown without zod schema validation — missing metadata on 10-20% of pages.
Image optimization ignored
Using <img> instead of <Image> loses 30-50% in load speed and LCP.
Dev mode in production
Accidental dev-build deploys = massive JS bundle and speed loss.
Static marketing without updates
Static sites without CI/CD auto-deploy on content changes — Google doesn't see freshness.
Six steps from audit to result
Configuration audit
Review astro.config, integrations, server-output. SSG vs SSR vs hybrid.
Core Web Vitals
PageSpeed Insights + Chrome DevTools for all page types.
Schema.org and meta
Unified system via Layout component and Content Collections with zod validation.
Sitemap, robots, hreflang
@astrojs/sitemap setup, robots exclusions, multilingual markup.
Content and interlinking
Internal link structure, breadcrumbs, related blocks on every page.
Monitoring
GSC, regular speed and indexation reports every 2 weeks.
How we approach modern stacks
Technical foundation first
On modern stacks, every SEO strategy starts with correct rendering and indexation. Nothing else works without it.
Core Web Vitals as a baseline
LCP, INP, CLS — the three metrics Google uses to grade real UX. SSG/SSR stacks make them easy to push into the green.
JS development with SEO in mind
We work directly with your developers — fixing what SEO tools alone can't reach.
Metric-driven monitoring
Not 'set it and forget it' — weekly reports on indexation, speed, and rankings with real numbers.
