TL;DR: For most posts, 3–8 internal links is a solid range. The right number depends on length and how much related content you have.

A Practical Rule Of Thumb

• Short posts (500–900 words): 3–5 internal links
• Medium posts (900–1,500 words): 5–8 internal links
• Long posts (1,500+ words): 8–12 internal links

What Matters More Than The Number

• Relevance (link to pages that truly help the reader)
• Placement (contextual links inside the body are best)
• Anchor text (tell Google and humans what they’ll get)

Where To Place Internal Links:

1. Near the top: 1 link to a foundational page or service page (if relevant).
2. In the middle: 1–3 links to supporting how-to or related posts.
3. Near the end: 1–2 links to “next step” content.

What To Avoid:

• Stuffing links for SEO only
• Linking 15 times to the same page
• Using vague anchor text like “click here”
