Astro pSEO at scale: architecture and hands-on guide
From zero to a self-generating long-tail landing page architecture using Astro plus structured data.

What readers are asking
Questions that keep coming back in reader feedback, already answered.
- 01
Why is my Astro component's interactivity not working?
Components ship as zero-JS HTML by default, so an interactive one needs a client:* directive (client:load, client:visible, …). Without it the script is never bundled into the page.

Which Astro version supports the @tailwindcss/vite integration reliably?
Astro 5 and later officially recommend the @tailwindcss/vite plugin over the old PostCSS route. Pin the astro and tailwind major versions before upgrading, or the new plugin silently ignores your v3 config.
