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
