How to Improve Content Readability (Practical Guide)

Readable content holds attention, reduces bounce rate, and is more likely to earn links and social shares. This guide explains the fastest, most effective ways to raise your readability scores and — more importantly — actually communicate clearly.

The two main levers

Every readability formula (Flesch, Flesch-Kincaid, Gunning Fog) punishes the same two things:

1. Long sentences — more words per sentence = higher grade level
2. Complex words — more multi-syllable words = harder to read

Reducing both is the core of any readability improvement.

1. Shorten your sentences

Target: average 15–20 words per sentence for general web content.

Before	After
"In order to maximise the effectiveness of your content strategy in the current competitive landscape, it is essential that you regularly audit and refine your approach."	"To get results from your content strategy, audit it regularly."

How:

• Split sentences at conjunctions: replace ", and", ", but", ", which" with a full stop and a new sentence.
• Cut throat-clearing phrases: "It is important to note that…", "In the context of…", "As mentioned previously…"
• One idea per sentence. If a sentence contains two commas, check whether it holds two ideas.

2. Replace complex words with simpler ones

Target: Gunning Fog score ≤ 12 for general audiences.

Complex	Simpler
utilise	use
ameliorate	improve
demonstrate	show
facilitate	help
approximately	about
commencement	start
subsequently	then / next

Keep technical terms where they are genuinely necessary and your audience expects them — replacing "API authentication" with "login checking" in a developer article creates confusion, not clarity.

3. Use the active voice

Passive voice adds syllables and length without adding meaning.

Passive	Active
"The report was completed by the team."	"The team completed the report."
"Improvements can be made to the process."	"You can improve the process."

4. Break up long paragraphs

Readers scan — walls of text cause abandonment. A paragraph should cover one idea and run no longer than 4–5 lines in a typical article format.

Use:

• Bullet points for lists of 3+ parallel items
• Numbered lists for sequential steps
• Subheadings (H2/H3) every 200–300 words to give readers anchor points

5. Write for your actual audience

A Flesch RE of 70 is not always the target:

• Consumer blog / landing page: 65–75 (Grade 7–8)
• General news / explainer: 55–65 (Grade 8–10)
• Technical documentation: 30–50 is acceptable — developers and engineers expect precise language
• Legal / medical disclaimer: 20–40 is normal — but consider a plain-language summary above the dense section

6. Read it aloud

If you stumble while reading aloud, your reader will stumble in their head. Every stumble is a reason to leave.

Quick wins checklist

• Average sentence length ≤ 20 words (check your Readability Score)
• Replace at least one "utilise / facilitate / demonstrate" with simpler synonyms
• Break any paragraph over 5 lines into two
• Add a subheading every 250 words
• Remove throat-clearing openers ("In this article, we will discuss…")
• Flesch Reading Ease ≥ 60 for a general audience

Readability does not mean dumbing down

Clarity and depth are not opposites. The world's most effective communicators — from great scientists to great writers — express complex ideas in clear language. Readability improvements almost always make content more persuasive and trustworthy, not less intelligent.
