The 6 most common Astro SEO issues
What we find on the average Astro site within the first scan.
Hydration islands shipping unused JS
client:load on components that don't need hydration ship extra JS.
Sitemap integration missing dynamic routes
@astrojs/sitemap excludes getStaticPaths-generated routes if not declared.
Missing canonical on i18n routes
Default Astro i18n doesn't emit canonical/hreflang automatically.
Image component not used for hero
Raw <img> tags skip Astro's image optimization, LCP suffers.
RSS feed misconfigured
/rss.xml ships without atom:link self-reference, feed readers drop it.
Content Collections without schema validation
Posts publish without title/description, breaking meta tags downstream.
Why a Astro-specific audit matters
- Astro ships zero JS by default, but defaults aren't perfect. We catch what makes it through.
- We detect Astro vs Astro+integrations and tailor findings (sitemap, image, RSS, MDX).
- Findings ship with .astro snippets and astro.config.mjs config diffs.
- Works on Vercel, Netlify, Cloudflare Pages, Deno Deploy.
