The file

We split this skill into the rules it gives an agent

2 rules. 0 are common, 2 are distinctive, and 0 are very specific to this project.

  • 0

    Common

    Most of the 145 edited versions we read keep these.

  • 2

    Distinctive

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Only one H1 per page — must differ from title but include primary keyword

    line 24
  2. Distinctive:

    Search intent match: informational, navigational, transactional, commercial

    line 38

“Common” is measured: kept by at least 6 in 10 of the 145 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Critical Rules

On-Page Fundamentals

  • Title: 50-60 chars, primary keyword in first 30 chars, unique per page
  • Meta description: 150-160 chars, benefit-focused, call-to-action
  • Only one H1 per page — must differ from title but include primary keyword
  • H1 → H2 → H3 strict hierarchy — never skip levels
  • Primary keyword in: title, H1, first 100 words, URL
  • Keyword density under 3% — stuffing triggers penalties

Technical Essentials

  • Core Web Vitals: LCP < 2.5s, INP < 200ms, CLS < 0.1
  • Mobile-first indexing: Google indexes mobile version — test mobile rendering
  • Canonical URL on every page — prevents duplicate content penalties
  • robots.txt: don't block CSS/JS, Google needs them to render
  • XML sitemap: max 50K URLs per file, submit in Search Console
  • HTTPS required — mixed content breaks security indicators

Content Signals

  • Search intent match: informational, navigational, transactional, commercial
  • E-E-A-T for YMYL: Experience, Expertise, Authoritativeness, Trustworthiness
  • Thin content penalty: pages under 300 words with no unique value
  • Content freshness: update dates matter for time-sensitive queries

Penalties to Avoid

  • Hidden text with CSS or font-size:0 — immediate penalty
  • Duplicate title tags across pages — wastes crawl budget
  • Keyword stuffing in alt text — unnatural patterns detected
  • Cloaking: showing different content to users vs bots
  • Link schemes: buying links, excessive link exchanges
