Internal Link Analysis + Generation

What This Skill Does

Two functions:

Good internal linking:

• Helps Google find all your pages
• Distributes "link juice" (ranking power) to important pages
• Guides users through your content

Why Internal Links Matter

• Orphan pages (no internal links) = Google can't find them = not indexed
• Deep pages (6+ clicks from homepage) = Google thinks they're not important
• Link hoarding (homepage links to everything) = diluted equity per link
• Poor anchor text = Google doesn't understand what the linked page is about

Check Categories

1. Orphan Pages

Pages with ZERO internal links pointing to them.

How to find:

1. Crawl entire site to find all pages
2. Check which pages have no inbound internal links
3. Cross-reference with sitemap (orphan pages often only accessible via sitemap)

Severity:

• Orphan + in sitemap = Medium (Google can find via sitemap, but weak)
• Orphan + not in sitemap = Critical (Google may never find it)

2. Click Depth Analysis

Rule: Important pages should be within 3 clicks of homepage.

3. Internal Link Distribution

PageRank flow analysis:

• Which pages receive the most internal links?
• Which pages receive the fewest?
• Does distribution match business priority?

Common problems:

4. Anchor Text Analysis

Good anchor text:

• Descriptive of target page content
• Contains relevant keywords naturally
• Varies across different linking pages

Bad anchor text patterns:

5. Broken Internal Links

Links pointing to 404 pages within your own site.

Impact:

• Wastes link equity
• Bad user experience
• Wastes crawl budget

6. Nofollow on Internal Links

Using rel="nofollow" on internal links = bad practice.

When it's wrong:

• Regular content links marked nofollow
• Navigation links marked nofollow

When it's acceptable:

• User-generated content (comments)
• Login/signup pages (PageRank sculpting is dead, but still ok)

7. Link Equity Sinks

Pages that receive lots of internal links but provide no value:

• Thank you pages
• Login pages
• Terms of service (linked from every page footer)

Solution: Add nofollow or reduce links to low-value pages.

8. Contextual vs Navigation Links

Goal: Important pages should have BOTH navigation AND contextual links.

Analysis Method

Step 1: Crawl Site

• Use crawler to discover all pages
• Record all internal links (source URL, target URL, anchor text)

Step 2: Build Link Graph

• Create adjacency matrix of page relationships
• Calculate inbound/outbound link counts per page

Step 3: Calculate Metrics

• Click depth: BFS from homepage
• Internal PageRank: Simplified PageRank calculation
• Orphan detection: Pages with 0 inbound links

Step 4: Cross-Reference with Goals

• Which pages should rank? (money pages, pillar content)
• Do those pages have strong internal link support?
