10 Techniques to Improve Readability
1. Shorten Your Sentences
Average sentence length should be under 20 words. Break long sentences at natural pauses. If a sentence has more than one comma, it can probably be split into two. This single change typically improves readability scores by 10-15 points.
2. Use Simpler Words
Replace multi-syllable words with simpler alternatives: "utilize" becomes "use," "approximately" becomes "about," "demonstrate" becomes "show," "facilitate" becomes "help." Each syllable reduction improves your Flesch score.
3. Use Active Voice
"The team completed the project" (active) beats "The project was completed by the team" (passive). Active voice is shorter, clearer, and more engaging. Aim for 80%+ active voice in your content.
4. Break Up Long Paragraphs
Keep paragraphs to 2-4 sentences for web content. Long paragraphs increase cognitive load and scare mobile readers. Find the natural break point where the topic shifts slightly and start a new paragraph.
5. Add Subheadings Every 200-300 Words
Subheadings provide visual breaks, aid scanning, and improve content structure for both readers and search engines. Descriptive subheadings that summarize the section below are most effective.
6. Eliminate Filler Words
Cut "very," "really," "actually," "basically," "literally," "in order to," and "due to the fact that." These add words without adding meaning. "In order to improve" becomes simply "to improve."
7. Use Contractions
Write "don't" instead of "do not," "it's" instead of "it is." Contractions reduce word count and create a conversational tone that scores higher on readability metrics while feeling more natural to readers.
8. Replace Jargon with Plain Language
Unless writing for specialists, replace industry jargon with common language. "Leverage synergies" becomes "work together effectively." Your readers should not need a dictionary to understand your content.
9. Use Transition Words
Words like "however," "therefore," "because," "first," and "meanwhile" help readers follow your logic. Content with transition words scores higher on readability because it guides the reader through the argument smoothly.
10. Read Aloud and Edit
The best readability test is reading your content aloud. If you stumble, the sentence is too complex. If you run out of breath, the sentence is too long. Awkward phrasing that looks fine on screen becomes obvious when spoken.
Readability and Engagement
Content with readability scores of 60-70 has nearly half the bounce rate of content scoring 30-40. This is a massive difference in user engagement that directly affects SEO through behavioral signals. Improving readability is one of the highest-ROI optimizations you can make.

What is a good readability score for a blog?
A Flesch Reading Ease score of 60-70 is ideal for most blogs. This represents an 8th-9th grade reading level that most adults find comfortable. Scores above 70 are great for general audiences. Scores below 50 are too complex for most web content.
How does readability affect SEO?
Google does not use readability as a direct ranking factor, but readable content gets lower bounce rates, higher time on page, and more shares — all indirect ranking signals. Content that scores above 60 significantly outperforms lower-scoring content on engagement metrics.
What is the Flesch Reading Ease formula?
Flesch Reading Ease = 206.835 - (1.015 x average words per sentence) - (84.6 x average syllables per word). Higher scores mean easier reading. The formula rewards shorter sentences and simpler words.
How do I make my writing more readable?
Use shorter sentences (under 20 words average), simpler words (prefer "use" over "utilize"), active voice, and short paragraphs (2-4 sentences). Break up long sections with subheadings every 200-300 words.
What readability level should I write at?
For web content, write at a 6th-8th grade level (Flesch-Kincaid Grade Level 6-8). This is not about dumbing down content — it is about clear, efficient communication. Most best-selling authors write at a 7th grade level.
