I’ve seen conflicting advice about readability and AI search:

Claim 1: “AI prefers simple, clear content - aim for grade 8 reading level”

Claim 2: “Complex, expert content shows authority - don’t dumb it down”

My questions:

  • Is there actual data on readability and AI citations?
  • Does simpler always mean better?
  • How do you balance accessibility with expertise?
  • Does this vary by topic or audience?

As a writer, I want to know if I should change my style.

We studied this. Here’s what the data shows:

Research methodology:

  • 1,200 content pieces across industries
  • Measured Flesch-Kincaid grade level
  • Tracked AI citation rates over 6 months
  • Controlled for topic, authority, and freshness

Results:

Reading LevelCitation RateIndex
Grade 5-718%0.9
Grade 8-1024%1.2
Grade 11-1221%1.05
Grade 13+16%0.8

Key findings:

  1. Sweet spot is grade 8-10 - ~30% better performance than extremes
  2. Very simple underperforms - May signal lack of depth
  3. Very complex underperforms - Harder to extract clear answers
  4. Effect is moderate - Content quality matters more

The nuance:

Readability matters for EXTRACTION, not preference. AI doesn’t “prefer” simple content. It can more reliably extract clear answers from moderately readable content.

So grade 8-10 is optimal. But does that mean I should target that number, or focus on clear writing and see where it lands?

Focus on clear writing, not the number.

What actually matters:

  1. Clear answer statements - Can AI extract a direct quote?
  2. Logical structure - Does the content flow?
  3. Appropriate complexity - Does it match the topic?
  4. Active voice - Easier to parse than passive

What doesn’t help:

  • Artificially simplifying expert content
  • Adding filler to lower complexity
  • Removing nuance for simplicity

Practical guidance:

Write naturally for your audience. Then check:

  • Are your key points clearly stated?
  • Could someone quote your answer directly?
  • Is complexity appropriate to topic?

If yes to all, readability score is secondary.

The danger of gaming readability:

Dumbing down expert content damages credibility. E-E-A-T signals suffer. You might improve extraction but lose authority.

Technical content perspective:

Our challenge:

We write about complex enterprise software. Grade 8 reading level would be impossible without losing accuracy.

What we learned:

Readability score matters less than ANSWER CLARITY.

Example:

Complex technical explanation (Grade 14): “The system utilizes a multi-threaded architecture with asynchronous processing capabilities that enable parallel execution of data transformation operations…”

Same concept with clear answer lead: “The system processes data faster through parallel execution. It uses a multi-threaded architecture with asynchronous processing capabilities that enable parallel data transformation…”

The second version:

  • Still technically accurate
  • Lead sentence is extractable
  • Grade level slightly lower but still expert
  • AI can quote the clear statement

The strategy:

Keep technical depth but lead with extractable statements. AI grabs the clear sentence; interested readers get the detail.

Consumer content perspective:

For B2C, simpler IS often better:

Our testing showed:

  • Grade 6-8 content: 31% citation rate
  • Grade 9-11 content: 24% citation rate
  • Grade 12+ content: 18% citation rate

Why the difference from B2B:

Consumer queries are simpler. User expectations are different. “What’s the best coffee maker?” doesn’t need technical complexity.

The audience match:

  • Consumer content -> Match consumer reading levels
  • B2B content -> Match professional reading levels
  • Technical content -> Match expert reading levels

Don’t apply one standard to all:

Grade 8 is optimal FOR CONSUMER CONTENT.

It might be terrible for technical documentation or academic topics.

Match your audience, not a universal benchmark.

Writing coach perspective:

Readability tips that help AI (and humans):

1. Front-load answers

  • Bad: “There are many factors that contribute to…”
  • Good: “The main factor is X. Here’s why…”

2. Use active voice

  • Bad: “The product was created by our team…”
  • Good: “Our team created the product…”

3. One idea per sentence

  • Bad: “The software integrates with many platforms including CRM systems, marketing automation tools, and analytics dashboards, making it a versatile solution.”
  • Good: “The software integrates with many platforms. This includes CRM systems, marketing automation tools, and analytics dashboards.”

4. Clear transitions

  • Bad: “Additionally, furthermore, however…”
  • Good: “Also,” “But,” “Next…”

5. Avoid jargon walls

  • Bad: “Leverage synergies to optimize ROI via strategic KPI alignment”
  • Good: “Combine efforts to improve results by focusing on key metrics”

These improve readability AND AI extraction. Win-win.

Great discussion. Here’s my synthesis:

What the data shows:

  1. Moderate correlation - Grade 8-10 performs slightly better overall
  2. Context matters - Consumer vs B2B vs technical have different optima
  3. Clarity > score - Clear answers matter more than raw readability
  4. Match your audience - Don’t artificially simplify expert content

What I’m taking away:

  1. Focus on answer clarity - Can AI quote my key points directly?
  2. Front-load answers - Put clear statements first
  3. Match audience - Consumer content simpler, technical content as needed
  4. Check, don’t obsess - Readability score is a check, not a goal

My new editing checklist:

  • Is the answer to the main question clearly stated?
  • Could someone quote my first sentence as an answer?
  • Is complexity appropriate for my audience?
  • Am I using active voice and clear structure?

If yes to all, I don’t worry about the grade level number.

Thanks everyone for the nuanced perspective!

Frequently Asked Questions

Does readability score affect AI citations?
Research suggests moderate correlation - content with reading level around grade 8-10 tends to perform better than highly complex or overly simple content. However, content quality and relevance matter more than readability score alone.
What readability level is best for AI search?
Aim for Flesch-Kincaid grade level 8-10 for most content. This balances accessibility with demonstrating expertise. Technical content may require higher complexity. The key is clarity of answers, not raw readability scores.
Why might readability affect AI citations?
AI systems extract information more reliably from clear, direct writing. Complex sentence structures can make answer extraction difficult. Simple, clear statements are easier for AI to quote accurately.
Should I simplify all content for AI?
No. Match complexity to audience and topic. B2B technical content may need higher complexity to demonstrate expertise. Consumer content benefits from simplicity. Focus on clear answer statements regardless of overall complexity.
