Feedback

When the user wants to fix indexing issues from Search Console, use noindex, or implement Google Indexing API. Also use when the user mentions "fix indexing," "not indexed," "Crawled - currently not indexed," "discovered - currently not indexed," "index coverage," "noindex," "noindex tag," "pages not indexed," "why not indexed," "request indexing," or "Google Indexing API." For sitemap, use xml-sitemap.

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.

Page Removal Decision Framework

When intentionally removing a page from the web, choose the method based on whether a relevant alternative exists and whether the page should remain accessible:

Scenario Method Rationale
Has a closely related replacement page 301 redirect Preserves accumulated link signals and user flow
Content merged into a new page 301 redirect Direct old URL to the new canonical location
Permanently deleted, no alternative 410 Gone Explicitly signals permanent removal to search engines
Deleted, uncertain if permanent 404 Not Found Safe default; can reinstate later if needed
Still accessible but should not be indexed noindex Page remains available to users; excluded from SERP

Before removing: Check the URL's search traffic, backlinks, internal links, and conversion value. If the page has value, consider updating or merging rather than removing.

Common mistakes:

  • 404-ing pages that have relevant alternatives (wastes accumulated signals)
  • Redirecting all deleted pages to the homepage (breaks user intent)
  • Creating redirect chains (A → B → C) instead of direct redirects
  • Removing pages without cleaning up internal links pointing to them
  • Using robots.txt to block noindex pages (crawler must access the page to read the noindex directive)

Post-removal cleanup:

  1. Remove deleted URLs from XML sitemap; update and resubmit
  2. Update internal links to point directly to the final URL (avoid relying on redirects)
  3. For 301 redirects, ensure the target URL is in the sitemap
  4. In GSC, use URL Inspection to verify important pages; use Removals tool for temporary quick-hide (not permanent — use proper HTTP status or noindex)

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).
