When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for language/locale and indexing goals.
Identify:
Three non-negotiables: (1) Self-referencing tags (each page links to itself), (2) Symmetric annotations (every version lists ALL others), (3) Valid ISO 639-1 or language-region codes (en, en-US, zh-CN).
Implementation methods: HTML <link> in head, XML sitemap (xhtml:link), or HTTP headers. For SPAs/JS-rendered pages, use sitemap-based hreflang as backup. See rendering-strategies for SSR/SSG/CSR.
Canonical alignment: Canonical URL must match the same regional version hreflang refers to. Misalignment causes Google to ignore hreflang.
x-default: Fallback for users whose language/location doesn't match any version. Point to default locale or language-selector page.
export const metadata = {
alternates: {
languages: {
'en-US': '/en/page',
'zh-CN': '/zh/page',
'x-default': '/en/page',
},
},
};
<link rel="alternate" hreflang="en" href="https://example.com/en/page" />
<link rel="alternate" hreflang="zh" href="https://example.com/zh/page" />
<link rel="alternate" hreflang="x-default" href="https://example.com/en/page" />
Page-level control for indexing and link following. See indexing for which page types typically need noindex.
| Directive | Effect |
|---|---|
noindex | Exclude page from search results |
nofollow | Do not pass link equity through links on the page; does NOT prevent indexing |
noindex,follow | Exclude from SERP; allow crawlers to follow links (most common for thank-you, signup, legal) |
noindex,nofollow | Exclude + block link flow (login, staging, test pages) |
Crawl vs index vs link equity: robots.txt = crawl control; noindex = index control; nofollow = link equity only. See robots-txt, indexing.
<meta name="robots" content="noindex, follow">
Next.js: metadata.robots = { index: false, follow: true }. Default is index: true, follow: true.
<meta name="viewport" content="width=device-width, initial-scale=1">
Required for mobile-friendly pages; affects Core Web Vitals and mobile search. For full mobile-first indexing and mobile usability requirements, see mobile-friendly.
<meta charset="UTF-8">
Place in <head>; first child of <head> recommended.
