name: seo description: SEO - meta tags, structured data. Use when optimizing for search.

SEO Guideline

Tech Stack

• Framework: Next.js (with Turbopack, SSR-first)

Non-Negotiables

• Every page must have complete metadata (title, description, canonical, OG, Twitter Cards)
• Canonical URLs must be correct (no duplicate content)
• Complete favicon set (ico, svg, apple-touch-icon, PWA icons)
• Structured data (JSON-LD) for rich results where applicable
• Security headers configured (CSP, HSTS, X-Frame-Options, X-Content-Type-Options)

Required Files

• robots.txt — search engine crawling rules
• sitemap.xml — page discovery for search engines
• llms.txt — LLM/AI crawler guidance
• security.txt — security vulnerability reporting (at /.well-known/security.txt)
• ads.txt — if ads exist
• app-ads.txt — if mobile ads exist

Context

SEO is about being found when people are looking for what you offer. Good SEO isn't tricks — it's making content genuinely useful and technically accessible to search engines and AI crawlers.

Driving Questions

• Is every page's head complete with all required meta tags?
• Are Open Graph and Twitter Cards generating correct previews?
• Is structured data present and validated?
• Do all required files exist and pass validation?
• Is the site accessible to both search engines and LLM crawlers?
• Are security headers properly configured?
