CANON · SEO

Technical SEO is about making content findable and understandable by search engines. Not tricks — structure.

Semantic HTML is SEO

Search engines understand semantic HTML natively. Every rule in canon-accessibility that improves screen reader experience also improves SEO.

<h1> once per page, matching the page topic.
Heading hierarchy (h1 → h2 → h3) reflects content structure.
<nav>, <main>, <article>, <aside> help crawlers understand page layout.
<a href> for links (not <div onClick>).
<img alt> describes the image for image search.

Essential meta tags

<head>
  <title>Page Title — Site Name</title>
  <meta name="description" content="Concise summary under 155 characters.">
  <link rel="canonical" href="https://example.com/page">
  <meta name="robots" content="index, follow">
</head>

<title>: 50–60 characters. Unique per page. Primary keyword near the front.
<meta description>: 120–155 characters. Compelling summary. Unique per page.
<link rel="canonical">: prevents duplicate content penalties.
<meta robots>: index, follow is default. noindex for admin pages.

Structured data (JSON-LD)

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "Page Title",
  "author": { "@type": "Person", "name": "Author" },
  "datePublished": "2026-04-18"
}
</script>

Use for: articles, products, FAQs, breadcrumbs, organizations, events. Google uses structured data for rich results (stars, prices, FAQ dropdowns).

Page speed = ranking factor

Core Web Vitals are a Google ranking signal. See canon-performance for targets:

LCP ≤ 2.5s
INP ≤ 200ms
CLS ≤ 0.1

Crawlability

robots.txt: allow crawlers access to important pages, block admin/API routes.
sitemap.xml: list all public pages with <lastmod> dates.
Internal linking: every important page reachable within 3 clicks from the homepage.
No orphan pages (pages with no internal links pointing to them).

Anti-patterns

Anti-pattern	Why it fails
Same `<title>` on every page	Search engines can't distinguish pages
No `<meta description>`	Search engine generates one (often badly)
Keyword stuffing	Penalized by modern search engines
Client-rendered content without SSR/SSG	Crawlers may not execute JS
No canonical URL	Duplicate content across www/non-www, http/https
Blocking CSS/JS in robots.txt	Crawlers can't render the page
