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
- Fix technical blockers before content optimization.
- One page should have one clear primary search intent.
- Prefer long-term quality signals over manipulative patterns.
- Mobile-first assumptions matter because indexing is mobile-first.
- Recommendations should be page-specific and implementable.
Technical SEO checklist
#### Crawlability
robots.txtshould 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:
ProductandOffer
- interior pages:
BreadcrumbList
- Q&A sections:
FAQPageonly 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
H2andH3should reflect actual content hierarchy
- do not skip structure just for visual styling
Keyword mapping
- define the search intent
- gather realistic keyword variants
- prioritize by intent match, likely value, and competition
- map one primary keyword/theme to one URL
- 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-pattern
Fix
keyword stuffing
write for users first
thin near-duplicate pages
consolidate or differentiate them
schema for content that is not actually present
match schema to reality
content advice without checking the actual page
read the real page first
generic “improve SEO” outputs
tie every recommendation to a page or asset
