SEO Technical: Indexing

Guides indexing troubleshooting and fix actions. For how to find and diagnose issues in GSC, see google-search-console.

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.

Scope (Technical SEO)

• Fix actions: noindex, canonical, content quality, URL Inspection; verify robots.txt does not block (see robots-txt)

• Noindex: Page-level index control; which pages to exclude and how. Complements robots-txt (path-level crawl control) and google-search-console (Coverage diagnosis)

Initial Assessment

Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for site URL and indexing goals.

Identify issue from GSC (see google-search-console for Coverage report, issue types, diagnosis workflow). Then apply fix below.

Crawled - Currently Not Indexed

Cause Action

Low quality, duplicate, off-topic Improve content, fix duplicates, set correct canonical

Static assets (CSS/JS) See below

Feed, share URLs with params Usually OK to ignore; or noindex, canonical to main URL

Important content pages Use URL Inspection, verify canonical/internal links/sitemap, Request indexing

Static Assets (Next.js / Vercel)

Vercel adds unique dpl= params to static assets per deploy, creating many "Crawled - currently not indexed" URLs.

Do Don't

Keep robots.txt allowing /_next/

Do not block /_next/ (breaks CSS/JS loading). See robots-txt

Accept static assets in GSC as expected Do not block /_next/static/css/ or ?dpl=

Use X-Robots-Tag for static assets CSS/JS should not be indexed; no SEO impact

Static assets in "Crawled - currently not indexed" is normal and expected.

Other Issue Types (from GSC Coverage)

Issue Fix

Excluded by «noindex» tag Remove noindex if accidental; keep if intentional

Blocked by robots.txt See robots-txt; remove Disallow for important paths

Redirect / 404 Fix URL or add redirect

Duplicate / Canonical Set correct canonical; usually OK

Soft-404 Page returns 200 but content says "not found" or empty—Google may treat as 404. Fix: return 404 status for truly missing pages; or add real content for 200 pages

Soft-404

A soft-404 occurs when a page returns HTTP 200 but the content indicates the page doesn't exist (e.g. "Page not found" message, empty state). Google may treat it as 404 and exclude from index.

Fix When

Return 404 Page truly doesn't exist; use proper 404 status

Add content Page is intentional (e.g. empty search results); ensure substantive content or use noindex

Redirect If URL moved, use 301 to correct destination

Noindex Usage

• How: metadata.robots = { index: false } or <meta name="robots" content="noindex"> or X-Robots-Tag

• Rationale: Not all site content should be indexed; noindex is a valid choice for many pages

• Caution: Avoid noindex on important content pages

• With robots.txt: robots.txt = path-level crawl control; noindex = page-level index control. Do not block noindex pages in robots.txt—crawlers must access the page to read the directive. Use both: robots for /admin/, /api/; noindex for /login/, /thank-you/, etc. See robots-txt for when to use which.

• nofollow ≠ noindex: nofollow controls link equity only; it does not prevent indexing. To exclude from search, use noindex. See page-metadata for meta robots implementation.

Page Types That Typically Need Noindex

Category Page Types Typical Meta Reason

Auth & Account Login, Signup, Password reset, Account dashboard Login: noindex,nofollow ; Signup: noindex,follow

No search value; login indexed = security risk; signup follow allows crawl of Privacy/Terms links

Admin & Private Admin, Staging, Test pages, Internal tools noindex,nofollow

Not for public; avoid discovery

Conversion Endpoints Thank-you, Confirmation, Checkout success, Download gate noindex,follow

Post-conversion; no SERP value; allow link equity

System & Utility 404, Internal search results, Faceted/filter URLs noindex,follow or noindex,nofollow

Thin/duplicate; 404 = error state

Legal Privacy, Terms, Cookie Policy (optional) Often noindex,follow

Low-value indexed; reduces clutter

Duplicate & Thin Printer-friendly, Parameter URLs, Near-duplicate noindex,follow or canonical Duplicate content; canonical preferred when possible

Low-Value Media kit, Feedback board (external), Thin press noindex or index for brand queries Case-by-case

noindex,follow vs noindex,nofollow: Use noindex,follow for most cases—excludes from SERP but allows link equity. Use noindex,nofollow only for login (security), staging, or temporary test pages.

Google Indexing API

Type Typical use

JobPosting Job boards

BroadcastEvent Live platforms

Requirements: Enable Indexing API, create service account, add owner in Search Console, request quota (default 200 URLs/day).
