Orphan Pages Internal Linking Opportunities

Orphan Page Audit & Interlinking Brief Generator

You are running a complete SEO orphan page audit. The user has provided a domain as input via args. Your job is to execute every phase below in order, using the tools available, and produce a single downloadable HTML report file saved to the current working directory.

Input domain: {args}

PHASE 1 — Domain Normalization & Sitemap Discovery

1. Normalize the input domain:

   • Strip leading/trailing whitespace
   • If it doesn't start with http, prepend https://
   • If it doesn't have www. and the base domain resolves with it, use www.
   • Remove any trailing slash
   • Store as BASE_URL (e.g., https://www.example.com)

2. Fetch BASE_URL/robots.txt using WebFetch. Look for any Sitemap: directive — if found, use that URL as the sitemap location. If not found, default to BASE_URL/sitemap.xml.

3. Fetch the sitemap URL. Determine its type:

   • Sitemap index (<sitemapindex> tag present): extract all <loc> child sitemap URLs, fetch each one, and merge all <loc> URLs from every child sitemap into a single master URL list
   • Regular sitemap (<urlset> tag): extract all <loc> URLs directly

4. Store the full master URL list.

PHASE 2 — Blog URL Identification

From the master URL list:

1. Analyze all URL patterns to identify the blog/content section. Look for the URL prefix that appears most frequently in a uniform pattern. Common prefixes to check: /blog/, /articles/, /posts/, /insights/, /resources/, /learn/, /news/, /guides/

2. Select the prefix that best represents the blog content (most URLs, most uniform structure). If multiple prefixes qualify, include all of them.

3. Filter the master URL list to only include URLs matching the identified blog prefix(es). Exclude index/listing pages (e.g., BASE_URL/blog with no further slug). Store as BLOG_URLS.

4. If no blog prefix is identifiable from the sitemap, fetch BASE_URL homepage and look for a blog/articles navigation link, then fetch that page and extract all post URLs from it.

5. Log the total count: "Found {N} blog posts at {BASE_URL}"

PHASE 3 — Crawl & Build Inbound Link Map

Run a Workflow to crawl all blog posts in parallel. The workflow should:

Script logic:

• Take BLOG_URLS as the items list
• For each URL, spawn an agent that:
  • Fetches the page using WebFetch
  • Extracts ALL href links in the body/article content (not nav, header, footer) that point to other pages on the same domain matching the blog URL pattern
  • Normalizes all found links to absolute URLs (no trailing slash, no query params, no hash)
  • Returns { source_url, outbound_blog_links: [...] }
• Use schema: { type: 'object', properties: { source_url: { type: 'string' }, outbound_blog_links: { type: 'array', items: { type: 'string' } } }, required: ['source_url', 'outbound_blog_links'] }

After the workflow completes, aggregate results:

• Build inbound_count map: { url -> number } initialized to 0 for all BLOG_URLS
• Build inbound_sources map: { url -> [source_url, ...] } initialized to [] for all BLOG_URLS
• For each crawl result, iterate outbound_blog_links and increment the inbound count + push the source URL for each valid link

Classify every page:

• Orphan = 0 inbound links → store as ORPHAN_URLS
• Low-linked = 1–2 inbound links → store as LOW_LINKED_URLS
• Healthy = 3+ inbound links → store as HEALTHY_URLS

Build FULL_INBOUND_MAP: array of { url, inbound, linked_from } sorted descending by inbound count.

PHASE 4 — Keyword Research for Orphan Pages

Run a Workflow to get the top US search volume keyword for each orphan page. The workflow should:

Script logic:

• Take ORPHAN_URLS as the items list
• For each orphan URL, spawn an agent that:
  1. Extracts the slug from the URL (last path segment)
  2. Generates 6–8 keyword variants from the slug (convert hyphens to spaces, try variations with different word orders, add/remove qualifiers)
  3. Uses ToolSearch to load mcp__claude_ai_DataForSEO__kw_data_google_ads_search_volume, then calls it with the keyword variants, location_code: 2840 (United States), language_code: "en"
  4. Picks the keyword with the highest US monthly search volume as anchor_text
  5. Fallback: if DataForSEO returns no data or errors, convert the slug to a phrase (hyphens → spaces) as the anchor_text
  6. Fetches the page and writes a 2–3 sentence page_summary of what the page covers
  7. Returns { orphan_url, anchor_text, us_monthly_volume, page_summary }
• Use schema: { type: 'object', properties: { orphan_url: { type: 'string' }, anchor_text: { type: 'string' }, us_monthly_volume: { type: 'number' }, page_summary: { type: 'string' } }, required: ['orphan_url', 'anchor_text', 'us_monthly_volume', 'page_summary'] }

Store results as KEYWORD_DATA: map of { orphan_url -> { anchor_text, us_monthly_volume, page_summary } }

PHASE 5 — Generate Interlinking Briefs for Orphan Pages

Run a Workflow using a 2-stage pipeline over ORPHAN_URLS:

Stage 1 — Pass through keyword data (already computed, no agent needed — use the KEYWORD_DATA directly)

Stage 2 — For each orphan, spawn an agent that:

1. Receives orphan_url, anchor_text, page_summary, and the full BLOG_URLS list
2. Selects exactly 3 topically relevant source pages from BLOG_URLS (exclude the orphan itself; prefer well-linked, non-orphan pages)
3. Fetches each of the 3 source pages using WebFetch
4. For each source page produces:
   • source_url: the full URL of the source page
   • where_to_place: specific, precise description of the location within that page — naming the H2/H3 section, which paragraph, what content surrounds it. Must be specific enough that a content editor can navigate there without guessing
   • context_copy: minimum 300 characters of naturally flowing copy to be inserted at that location. The anchor_text MUST appear exactly once within it as <a href="ORPHAN_URL">ANCHOR_TEXT</a>. Copy must read as if it was always part of the article — not promotional, not forced. Same anchor text across all 3 placements.
5. Returns { orphan_url, anchor_text, placements: [{ source_url, where_to_place, context_copy }, ...] }

• Use schema with placements as array of 3 objects each requiring source_url, where_to_place, context_copy

After the workflow completes, post-process every context_copy:

• Check if anchor_text appears as a hyperlink (href="orphan_url" present)
• If not, find the first occurrence of anchor_text (case-insensitive) and replace with <a href="orphan_url">anchor_text</a>

Store as BRIEFS.

PHASE 6 — Generate HTML Report

Using the Write tool, save a single self-contained HTML file to the current working directory named orphan-audit-{domain}-{YYYYMMDD}.html where {domain} is the base domain (no protocol, no www, dots replaced with hyphens) and {YYYYMMDD} is today's date.

The HTML file must be completely self-contained — all CSS inline in a <style> tag, no external CDN or font imports, works offline. Use clean, professional design with the following structure:

HTML Report Structure

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <title>Orphan Page Audit — {domain}</title>
  <style>
    /* Full inline CSS — professional design, light background, clean typography */
    /* Use system fonts: -apple-system, BlinkMacSystemFont, 'Segoe UI', sans-serif */
    /* Color palette: #0f172a (headings), #334155 (body), #3b82f6 (accent/links), #f1f5f9 (backgrounds), #e2e8f0 (borders) */
    /* Stat cards, tables, collapsible sections, copy buttons */
  </style>
</head>
<body>

Section 1 — Header

• Site logo area with domain name (large)
• Audit date
• "Download Report" button (triggers window.print() or direct file save)

Section 2 — Executive Summary Four stat cards in a row:

• Total Blog Posts Found: {BLOG_URLS.length}
• Orphan Pages: {ORPHAN_URLS.length} + percentage of total
• Low-Linked Pages: {LOW_LINKED_URLS.length} (1–2 inbound links)
• Healthy Pages: {HEALTHY_URLS.length} (3+ inbound links)

A horizontal bar showing the proportion of orphan / low-linked / healthy visually.

Section 3 — Orphan Pages List Table with columns: # | Page URL (clickable link) | Anchor Text | US Monthly Volume One row per orphan page.

Section 4 — Inbound Link Map (Non-Orphan Pages) Table sorted descending by inbound count: Page URL | Inbound Links | Linked From For the "Linked From" column, list each source URL on a new line or as a comma-separated list.

Section 5 — Interlinking Briefs For each orphan page, a card containing:

• Orphan URL (h3, clickable)
• Anchor Text (badge/pill)
• US Monthly Search Volume
• Three placement blocks, each showing:
  • Source page URL (bold, clickable)
  • "Where to Place" — displayed as a styled blockquote or info box
  • "Context Copy" — displayed in a styled <pre> or <div> with a "Copy" button that uses navigator.clipboard.writeText() to copy the HTML

Section 6 — Footer

• "Generated by Infrasity Orphan Page Audit Skill"
• Audit date and domain

JavaScript (inline <script> tag)

• Copy button functionality: navigator.clipboard.writeText(element.innerText)
• Smooth scroll for any nav links
• Optional: collapse/expand for brief cards

PHASE 7 — Confirm & Report to User

After saving the HTML file:

1. Report the file path to the user
2. Give a brief summary:
   • Total blog posts found
   • Number of orphan pages
   • Number of interlinking briefs generated
   • File name and location
3. Note any pages where keyword data could not be fetched from DataForSEO (fell back to slug)

Important Rules

• Never hardcode /blog/ — always detect the URL pattern from the actual sitemap
• Anchor text is fixed per orphan — the same anchor_text string appears in all 3 context_copy blocks for that orphan, always as a hyperlink
• Context copy minimum 300 characters — enforce strictly; if an agent returns shorter copy, flag it
• Where to place must be specific — section heading + paragraph position + surrounding content context
• HTML report is self-contained — no external requests, no CDN, works offline
• DataForSEO fallback — if API returns no data, use the slug converted to a readable phrase
• Post-process hyperlinks — after all briefs are generated, always verify and fix anchor text hyperlinks before writing the HTML
• File naming — orphan-audit-{domain}-{YYYYMMDD}.html saved in the user's current working directory
