A low readability score is almost always fixable — and the fixes are mechanical, not creative. This guide walks through what readability actually measures, what a good score looks like for your audience, and seven practical edits that lift the score on any piece of writing.
What Is a Readability Score?
A readability score estimates how hard a piece of writing is to read. The two most common scales are Flesch reading ease (0–100, higher is easier) and Flesch–Kincaid grade level (US school grade required to understand the text).
Both formulas look at sentence length and syllable count. They are blunt instruments — they cannot tell whether your prose is interesting — but they reliably catch the two biggest readability killers: long sentences and long words.
For SEO and UX, readability matters because clearer content keeps readers on the page. You can check any draft instantly with a free readability checker before publishing.
What Is a Good Readability Score?
There is no universal good score — the right number depends on your audience.
| Score | Level | Best for |
|---|---|---|
| 70–80 | Easy | Consumer blogs, landing pages |
| 60–70 | Standard | Business blogs, how-to guides |
| 50–60 | Fairly difficult | B2B, technical content |
| 30–50 | Difficult | Academic, legal content |
Aim a few points higher than your audience strictly requires. Readers never complain that text is too easy to skim.
7 Practical Ways to Improve Readability
- Shorten sentences — Aim for under 20 words. Bad: "Despite the fact that the algorithm is complex, we decided to implement it because it provides better results." Good: "The algorithm is complex, but we use it because the results are better."
- Use common words — Choose "use" over "utilize", "help" over "facilitate", "start" over "commence". Plain words score higher and read faster.
- Break up long paragraphs — Keep paragraphs to three or four lines on desktop — one or two on mobile. White space invites the next sentence to be read.
- Write in active voice — Bad: "The report was reviewed by the team." Good: "The team reviewed the report." Active sentences are shorter and clearer.
- Add subheadings every 200–300 words — Subheadings give skimmers somewhere to land and Google extra context about page structure.
- Avoid jargon unless it earns its place — Industry terms are fine when your audience uses them — but define new ones on first use, or replace them with plain language.
- Read it aloud before publishing — If you stumble over a sentence, your readers will too. Fix the sentence, not your delivery.
Readability and SEO — The Connection
Google has stated repeatedly that readability is not a direct ranking factor. But it is a strong indirect one. Clearer content produces better engagement signals — lower bounce rates, longer time on page, more scroll depth — and those signals influence how Google evaluates page quality.
The Helpful Content update reinforced this. Pages that read like they were written for humans tend to satisfy intent better, which is exactly what the system is trying to reward.
Mobile reading habits raise the stakes. More than 60% of search traffic is mobile, where every long sentence and every five-syllable word costs you readers. A higher Flesch score is, in practice, a higher chance of being read at all.
If you want to track the raw score, a dedicated Flesch reading score calculator gives you the number plus a grade-level estimate side by side. For full SEO context — readability plus keyword balance plus headline length — use the broader SEO text analyzer.
