AEO best practices: engineering conventions for production
Field-tested AEO practices from production, avoiding the common anti-patterns.
Quick answer
Are AEO and GEO JSON-LD the same?
Both use schema.org, but AEO layers in entity authority (Organization / SameAs). Keep the version unified — two parallel schemas cause conflicts.

In-depth analysis
AEO (Answer Engine Optimization) targets answer engines like ChatGPT Search and Perplexity: make sure AI consistently cites your site as a source when it generates an answer. Production engineering conventions revolve around "single source of truth + explicit boundaries", steering clear of the common anti-patterns.

- Docs and code live in separate places
FAQ & pitfalls
How do I update AEO content after AI cites it?
Edit the destination page body and JSON-LD, rebuild static output, and update llms.txt. Engines re-fetch from the canonical URL.

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.

Why is my custom Tailwind v4 brand colour not applied?
Colours must be declared in @theme (for example --color-brand). A missing @tailwindcss/vite plugin, or a leftover v3 config, makes bg-brand silently render nothing.

Why are _headers / _redirects not taking effect?
Both files must sit at the root of the output directory (dist/); anything under src/ is never uploaded. A purely static project should not add _worker.js either — that gives up the zero-cold-start advantage.
