Seo

• 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.
