Getting conflicting advice on content length for AI search. Some say comprehensive, some say concise.

What I’m trying to understand:

  • What length actually performs best for AI citations?
  • Is there a sweet spot?
  • Does it depend on topic type?

Looking for data on what actually works.

Research data on content length and AI citations:

Word count correlation:

Content LengthAvg AI Citations
Under 800 words3.2
800-1,500 words3.8
1,500-2,900 words4.5
Over 2,900 words5.1

The nuance: Correlation, not causation. Long content isn’t cited BECAUSE it’s long - it’s cited because comprehensive coverage requires more words.

What actually matters:

  1. Completeness - Does it fully answer the query?
  2. Depth - Does it provide useful detail?
  3. Structure - Can AI extract relevant parts?

Section length sweet spot: 120-180 words between headings = 4.6 avg citations Under 50 words between headings = 2.7 avg citations

Thin sections hurt. Padded sections hurt. Substantive sections help.

The “comprehensive vs. concise” debate misses the point:

It’s about completeness, not word count.

For simple queries: “What is the capital of France?”

  • Concise works: “Paris is the capital of France.”
  • Long content is unnecessary padding

For complex queries: “How do I choose project management software for my team?”

  • Comprehensive works: Features, comparisons, use cases
  • Concise would be incomplete

The framework:

  1. What does this topic require to fully answer?
  2. Write that much - no more, no less
  3. If the topic is complex, it needs depth
  4. If simple, concise is better

Don’t pad to hit word counts. Don’t truncate to seem “concise.” Match length to topic complexity.

This clarifies the framework. Key takeaways:

Not about word count, about completeness:

  • Simple topics: Concise
  • Complex topics: Comprehensive
  • Match length to topic needs

Structure matters:

  • 120-180 words per section ideal
  • Very short sections hurt
  • Each section should be substantive

Our new approach:

  • Stop targeting word counts
  • Focus on complete topic coverage
  • Structure with substantive sections

Thanks everyone!

Frequently Asked Questions

How comprehensive should content be for AI search?
Research shows longer, more comprehensive content correlates with more AI citations. Articles over 2,900 words averaged 5.1 citations while those under 800 words averaged 3.2. However, depth and value matter more than raw word count.
Is there an ideal content length for AI visibility?
There’s no magic word count, but 1,500-3,000 words tends to perform well for comprehensive topics. The key is covering the topic thoroughly without padding. Shorter content works for simple questions; complex topics need more depth.
Does concise content ever outperform long content for AI?
Yes, for simple factual queries. AI may prefer concise, direct answers for basic questions. Long content works better for complex, multi-part queries where comprehensive coverage is needed.
How should content sections be structured for AI?
Optimal section length is 120-180 words between headings (4.6 avg citations). Very short sections under 50 words perform poorly (2.7 avg citations). Each section should fully address its topic without being bloated.
