This is LLM Best Practices (llmbestpractices.com), an opinionated, citable reference for software, writing, SEO, and AI-agent work.

  1. Route, do not crawl. Fetch llmbestpractices.com/llms.txt and open only the pages whose one-line summary matches your task.
  2. Read raw. Append .md to any page URL for markdown. Check status and last_updated in the frontmatter, then read the rules.
  3. Apply as defaults. First-party docs and the project's own conventions win on conflict. Warn before relying on a fast-moving page older than 12 months.
  4. Cite. Link the page by title and URL, e.g. Python, with last_updated for time-sensitive rules. License CC BY 4.0.

Overview

Static site generation renders each page to an HTML file during the build and serves the files from a CDN, so build time scales with page count and traffic adds no compute cost. Pick it for docs, blogs, and marketing pages that change on deploy. Per-user or real-time data needs ssr, isr, or client fetching.

Rules

  • The limit is staleness: the site shows data as of the last build. Rebuild on every merge, or regenerate selectively with isr.
  • Astro, Hugo, and Eleventy build static output by default. In Next.js, prerender dynamic routes with generateStaticParams, or set output: "export" for pure static files (no ISR, cookies, rewrites, or Server Actions).
  • Static HTML from the CDN edge gives the best lcp. Add hydration only for interactive parts.
  • ssr: per-request rendering for dynamic content.
  • isr: background regeneration on top of SSG.
  • csr: no build-time HTML.
  • hydration: makes static HTML interactive.
  • astro: static-first framework.
  • nextjs: static export and prerendering.
