1. Basic Definitions & Differences | Domain Perspective

In SEO, links are categorized into 3 types. The difference depends on the domain and your perspective:

If you want to learn SEO, it is very important to understand the work of an SEO professional logically. To perform SEO effectively, you must first understand how search engines work. A modern search engine operates through five main stages.

Internal Link: Linking one page to another page on the same website.

For example:

  • [abc.com/page1](https://abc.com/page1) âž” [abc.com/page2](https://abc.com/page2)
  • External Link: Linking a page from your website to another website (From the giving page’s perspective).

For example:

  • [abc.com/page1](https://abc.com/page1) âž” [xyz.com/page2](https://xyz.com/page2)

Backlink: Any incoming link received by a page from another page/domain (From the receiving page’s perspective).

For example: Any link pointing to Page 2.

Note: For the receiving page (Page 2), whether the link comes from an internal domain or an external domain, it is still considered a Backlink!

2. PageRank Distribution & Internal Link Value

  1. PageRank Concept: When Page A links to Page B, Page A passes a portion of its authority/value to Page B.
  2. The Pocket Analogy:
  • Creating internal links does not increase the overall domain authority (total weight) of the website.
  • Internal linking helps distribute the existing PageRank value of the domain to the right pages.

3. Key Benefits of Internal Links

  1. Website Structure: Gives a clear network structure to unlinked or orphan pages.
  2. Page Importance Signal: Pages that receive the highest number of internal links are treated as most important by Google.
  3. Fixing Technical Errors: Helps prevent Canonical Tag confusion and unnecessary redirect chains.

4. Technical Precautions (Avoid Redirect Errors)

An internal link must always point directly to the exact final URL structure:

  • HTTP vs HTTPS Error: Do not link an http:// page to an https:// page if it creates a redirect.
  • WWW vs Non-WWW Error: Do not link to [www.abc.com](https://www.abc.com) if your site structure uses abc.com.
  • Trailing Slash Error: Pay attention to whether the site uses a trailing slash ([abc.com/page](https://abc.com/page) vs [abc.com/page/](https://abc.com/page/)).
  • Consequence: Making these mistakes turns the link into a Redirect, which wastes PageRank and link value.

5. Surfer Models: How Google Values Links

[Random Surfer Model] ──── (Evolution) ────> [Reasonable Surfer Model] (Equal value for all links) (Value based on User Behavior & Position)

A. Random Surfer Model (Old Approach)

  • In its early stages, Google assumed a user could randomly click any link on a page (Header, Footer, and Privacy Policy links all had equal weight).

B. Reasonable Surfer Model (Modern Approach)

  • Google now assigns value based on logical user behavior:
    • Main Content Links: Highest Value
    • Header Links: Medium Value
    • Sidebar / Footer / Comment Links: Lowest or No Value

6. Position & UI Pitfalls

  • Above the Fold Advantage: The higher up a link is placed within the Main Content (Top Part), the more PageRank value it passes. Links placed further down pass lower values.
  • The “Contact Us” Trap:
    • If you place a Contact Us link/button at the top of every service page, a huge amount of PageRank gets collected on the Contact Us page.
    • Result: Your main Service/Money page fails to rank, and the contentless Contact Us page starts ranking in Google search results instead!

7. Internal Linking Architecture Strategy

Key Terms:

  1. Money Page (Service Page): The core page that generates business and conversions (e.g., best-dental-clinic-in-delhi). It does not need 1,000-word blog posts; it just needs to be professional and conversion-focused.
  2. Supporting Content Pages: Guides, Success Stories, Testimonials, Comparison Guides, Interviews, Whitepapers, Vocabulary pages.
  3. Pillar Page: A main hub page that lists and links out to all supporting content pieces on a given topic.

Link Passing Rules (Top vs Bottom Placement)

Rule 1: Passing High PageRank (Green Links = TOP Part)

  • Pillar Page âž” Supporting Pages: Place links to all supporting content pages (Guides, Testimonials, etc.) in the Top Part of the Pillar Page so they receive strong PageRank.
  • Supporting Pages âž” Money Page: Place the link pointing to the Money Page in the Top Part (first few lines) of every supporting content page.
    • Reason: The primary goal is to pass maximum link value to the Money Page.

Rule 2: Passing Low Value (Red Links = BOTTOM Part)

  • Supporting Pages âž” Pillar Page: If supporting content pages need to link back to the Pillar Page, place those links in the Bottom Part of the main content.
    • Reason: This prevents supporting pages from draining their stored PageRank back to the Pillar Page.

Rule 3: Cross Category Rules

  • Cross Category / Vertical Links (e.g., Dentist vs Dermatology): Pages from unrelated services should not link to each other. If two different Pillar pages must be linked, place the link in the Middle Part so moderate value is passed without causing confusion.

Note:

  1. Primary Goal: The purpose is not just to rank supporting blog pages; the main objective is to rank the Money Page.
  2. Top Content Placement: The link to the Money Page should always be in the upper text section (Top Part) of supporting content pages.
  3. Audit Check: Search site:yourdomain.com. If your Contact Us or About Us page ranks higher than your main Service page, your internal link flow is flawed and needs correction!
