Overview

This skill teaches core SEO fundamentals covering E-E-A-T, Core Web Vitals, technical and content SEO, schema markup, and Google-friendly AI content practices. It focuses on practical signals and measurable targets to improve search visibility and user experience. Use it to align content, technical work, and measurement with ranking priorities.

How this skill works

The skill inspects and summarizes key SEO signals: experience/expertise/authoritativeness/trustworthiness, Core Web Vitals targets, site structure and performance elements, on-page content rules, and schema types. It translates those signals into concrete checks (e.g., LCP < 2.5s, INP < 200ms, CLS < 0.1), metadata guidelines, and content quality actions. It also maps metrics to tools for monitoring and prioritizes actions by likely ranking impact.

When to use it

  • Planning a new website or major redesign to bake SEO into architecture.
  • Auditing an existing site for performance, indexing, and content quality gaps.
  • Optimizing individual pages for search intent, metadata, and readability.
  • Validating AI-assisted content before publication to meet Google expectations.
  • Creating measurement dashboards and prioritizing SEO work by impact.

Best practices

  • Demonstrate first-hand experience and expert review in content to satisfy E-E-A-T.
  • Hit Core Web Vitals targets (LCP <2.5s, INP <200ms, CLS <0.1) and optimize mobile performance.
  • Use clear site structure: XML sitemap, robots.txt, canonical tags, and HTTPS.
  • Write unique, in-depth content with one H1, descriptive meta elements, and accessible alt text.
  • Apply appropriate schema (Article, FAQPage, Product, Review, etc.) to enhance SERP features.
  • Treat AI drafts as starting points—add original insights and human verification before publishing.

Example use cases

  • Pre-launch checklist for a product site: implement HTTPS, sitemap, canonical tags, and product schema.
  • Content refresh for a blog pillar: expand depth, add author credentials, update meta description and schema.
  • Performance sprint: reduce LCP via image optimization, server timing, and caching to improve Core Web Vitals.
  • AI-assisted article workflow: human edit, expert review, add unique examples, and mark up FAQ schema.
  • SEO prioritization workshop: rank issues by quality content, backlinks, page experience, mobile, then technical fixes.

FAQ

How important are Core Web Vitals compared to content quality?

Content quality is the highest priority, but Core Web Vitals materially affect user experience and can influence rankings and engagement metrics—optimize both.

Can I publish AI-generated content?

You can use AI drafts if you add human edits, original insights, and fact-checking to meet E-E-A-T and avoid thin or misleading content.

Which schema should I implement first?

Start with organizational and article/product schemas relevant to your pages, then add FAQ and review schemas where they add clear SERP benefit.
