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