Audit, plan, and implement SEO improvements across technical SEO, on-page optimization, structured data, Core Web Vitals, and content strategy. Use when the user wants better search visibility, SEO remediation, schema markup, sitemap/robots work, or keyword mapping.

We split this skill into the rules it gives an agent

9 rules. 0 are common, 8 are distinctive, and 1 is very specific to this project.

  • 0

    Common

    Most of the 133 edited versions we read keep these.

  • 8

    Distinctive

    This author's own choices. Worth a look.

  • 1

    Very specific

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

  2. Distinctive:

    Prefer long-term quality signals over manipulative patterns.

    line 27
  3. Very specific:

    no important page should be unintentionally noindex

    line 36
  4. Distinctive:

    avoid redirect chains longer than two hops

    line 38
  5. Distinctive:

    no duplicate URLs should compete without canonical control

    line 46
  6. Distinctive:

    put the primary keyword or concept near the front

    line 68
  7. Distinctive:

    do not skip structure just for visual styling

    line 81
  8. Distinctive:

    use descriptive anchor text

    line 94
  9. Distinctive:

    avoid generic anchors when a more specific one is possible

    line 95

“Common” is measured: kept by at least 6 in 10 of the 133 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.

SEO

Improve search visibility through technical correctness, performance, and content relevance, not gimmicks.

When to Use

Use this skill when:

  • auditing crawlability, indexability, canonicals, or redirects
  • improving title tags, meta descriptions, and heading structure
  • adding or validating structured data
  • improving Core Web Vitals
  • doing keyword research and mapping keywords to URLs
  • planning internal linking or sitemap / robots changes

How It Works

Principles

  1. Fix technical blockers before content optimization.
  2. One page should have one clear primary search intent.
  3. Prefer long-term quality signals over manipulative patterns.
  4. Mobile-first assumptions matter because indexing is mobile-first.
  5. Recommendations should be page-specific and implementable.

Technical SEO checklist

Crawlability

  • robots.txt should allow important pages and block low-value surfaces
  • no important page should be unintentionally noindex
  • important pages should be reachable within a shallow click depth
  • avoid redirect chains longer than two hops
  • canonical tags should be self-consistent and non-looping

Indexability

  • preferred URL format should be consistent
  • multilingual pages need correct hreflang if used
  • sitemaps should reflect the intended public surface
  • no duplicate URLs should compete without canonical control

Performance

  • LCP < 2.5s
  • INP < 200ms
  • CLS < 0.1
  • common fixes: preload hero assets, reduce render-blocking work, reserve layout space, trim heavy JS

Structured data

  • homepage: organization or business schema where appropriate
  • editorial pages: Article / BlogPosting
  • product pages: Product and Offer
  • interior pages: BreadcrumbList
  • Q&A sections: FAQPage only when the content truly matches

On-page rules

Title tags

  • aim for roughly 50-60 characters
  • put the primary keyword or concept near the front
  • make the title legible to humans, not stuffed for bots

Meta descriptions

  • aim for roughly 120-160 characters
  • describe the page honestly
  • include the main topic naturally

Heading structure

  • one clear H1
  • H2 and H3 should reflect actual content hierarchy
  • do not skip structure just for visual styling

Keyword mapping

  1. define the search intent
  2. gather realistic keyword variants
  3. prioritize by intent match, likely value, and competition
  4. map one primary keyword/theme to one URL
  5. detect and avoid cannibalization

Internal linking

  • link from strong pages to pages you want to rank
  • use descriptive anchor text
  • avoid generic anchors when a more specific one is possible
  • backfill links from new pages to relevant existing ones

Examples

Title formula

Primary Topic - Specific Modifier | Brand

Meta description formula

Action + topic + value proposition + one supporting detail

JSON-LD example

{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "Page Title Here",
  "author": {
    "@type": "Person",
    "name": "Author Name"
  },
  "publisher": {
    "@type": "Organization",
    "name": "Brand Name"
  }
}

Audit output shape

[HIGH] Duplicate title tags on product pages
Location: src/routes/products/[slug].tsx
Issue: Dynamic titles collapse to the same default string, which weakens relevance and creates duplicate signals.
Fix: Generate a unique title per product using the product name and primary category.

Anti-Patterns

Anti-patternFix
keyword stuffingwrite for users first
thin near-duplicate pagesconsolidate or differentiate them
schema for content that is not actually presentmatch schema to reality
content advice without checking the actual pageread the real page first
generic “improve SEO” outputstie every recommendation to a page or asset

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
