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.

What's included

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.

Common problems

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 schema validation: some pages ship without a title or description, and nobody notices for weeks.

Image optimization ignored

A plain image tag instead of the built-in component: images ship at original size and format, and the first screen takes noticeably longer.

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.

How we work

Six steps from audit to result

01

Configuration audit

Review astro.config, integrations, server-output. SSG vs SSR vs hybrid.

02

Core Web Vitals

PageSpeed Insights + Chrome DevTools for all page types.

03

Schema.org and meta

Unified system via Layout component and Content Collections with zod validation.

04

Sitemap, robots, hreflang

@astrojs/sitemap setup, robots exclusions, multilingual markup.

05

Content and interlinking

Internal link structure, breadcrumbs, related blocks on every page.

06

Monitoring

GSC, regular speed and indexation reports every 2 weeks.

How the rendering mode affects indexing

This is the central question on any modern framework. Everything else — meta tags, markup, speed — is decided after it.

ModeWhat a crawler seesWhen it fits
Static generationReady HTML with all content — the best case for indexingContent changes rarely: services, articles, catalogues without frequent price updates
Server renderingReady HTML assembled per requestData changes often: stock, prices, personalisation
Client renderingAn empty page; content appears after scripts runAccount areas and internal interfaces — things that should not be indexed anyway
Mixed modeDepends on which part of the page ships immediatelyCatalogues with static cards and dynamic blocks

A common mistake is client rendering on pages meant to bring people from search. Easy check: open the page source and search for your own text. If it is not there, a crawler may not see it either.

Adaptive Lab principles

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' — we watch indexation, speed and rankings continuously and send a report once a month.
