Write at a clear reading level
rule · reading-level
Readability measures how easily your target audience can understand your content. Complex writing causes users to leave quickly, which harms engagement metrics and weakens the same user-focused signals measured in content quality.
Code Examples
Passive to Active Voice

❌ "The configuration must be updated by the administrator before the deployment can be initiated."
✅ "The administrator must update the configuration before starting the deployment."Simplifying Jargon

❌ "Utilise the subsequent methodological framework to iteratively optimise your content strategy."

❌ "When you are designing a website and you want to ensure that users who visit your pages
find the content easy to read and understand, which is important for both user experience
and search engine optimisation, you should consider the reading level of your audience."
✅ "Clear writing improves both user experience and SEO. Write for your audience's reading
level. Consider their background knowledge when choosing vocabulary and sentence length."Why It Matters
Content written beyond the reading level of the target audience increases bounce rates and reduces time-on-page—both engagement signals that correlate with search rankings.

Structuring for Scanners
Research by Nielsen Norman Group shows 79% of users scan rather than read web content. Structure accordingly:
Text
✅ Use subheadings every 200–300 words
✅ Use bullet points for lists of 3+ items
✅ Bold key terms or takeaways
✅ Lead with the conclusion (inverted pyramid)
✅ One idea per paragraphIndustry Context
Reading level targets vary by audience:
- Medical / legal / technical: Grade 10–12 may be appropriate
- Consumer products / blogs: Grade 6–8 is ideal
- Children's content: Grade 3–5
- Academic / professional: Grade 12+ may be appropriate
Always match the expected reading level of your target audience.
Exceptions
- Necessary utility or compliance pages can be intentionally brief and should not be judged by the same editorial-depth expectations as ranking-focused content.
- AI-assisted drafting is not a failure by itself; flag unsupported claims, missing editorial review, or low-originality output instead.
- When a page has both trust-signal issues and crawl/index problems, make the page eligible to rank first and then improve the content quality signals.
Verification
Automated Checks
- Inspect rendered HTML and HTTP headers to confirm the expected metadata or crawlability signal is present.
- Test the affected URL with Google Search Console or equivalent tooling where relevant.
- Re-crawl a representative page set after deployment.
Manual Checks
- Confirm the change does not create conflicting canonical-url, robots, or structured-data signals.
