Does readability affect rankings?

Confirmed Based on 17,569 data points

What the Data Shows

Mid-range readability (40-60) pages get the most impressions. The spread is ~96% — readability clearly correlates with search visibility.

Bottom line: Aim for mid-range readability (40–60) if you want more search impressions.

How to Read This Chart

The X-axis shows readability score buckets. Each bar shows relative impressions for pages in that bucket. The tallest bar is the 40–60 range. Notice the drop on both ends and the ~96% spread between low and peak buckets.

Background

Many SEOs treat readability as “nice to have” and focus on links, intent, and templates. But readability changes how many queries your page can win, especially long-tail. We compared readability scores to relative impressions across 17K+ pages from a corpus of millions. Pages in the 40–60 readability range earned the most impressions, with a ~96% spread across buckets.

What to Do Next

  1. 1

    Export readability scores for your top 100 pages high

    Bucket pages by score and compare impressions per bucket.

  2. 2

    Rewrite 10 pages outside 40–60 with the most impressions gap high

    Shorten sentences, swap hard words, and keep all key headings and entities.

  3. 3

    Add a short summary and glossary blocks on technical pages medium

    Raise readability without cutting expert detail.

  4. 4

    Recheck scores after templates and nav are removed from the sample low

    Measure only the main content so changes map to rankings.

Best Practices

  1. 1

    Target readability 40–60 on key pages

    That range won the most impressions in our data. Outside it, visibility drops fast.

  2. 2

    Keep average sentence length under 20 words

    Short sentences raise clarity without dumbing down content. Long sentences push scores down and hurt skimming.

  3. 3

    Use plain words for core terms (then define the jargon)

    Plain words widen query match and reduce bounce from confused users. If you skip definitions, technical terms narrow your audience.

  4. 4

    Add a 2–3 line summary near the top

    A fast summary keeps the page readable even when details get complex. Without it, pages read “hard” and lose impressions.

Common Mistakes to Avoid

  • Chasing the highest score (70–90+) on expert topics

    You strip needed detail and weaken topical depth.

  • Measuring readability on the whole page, not the main content

    Nav, tables, and boilerplate skew the score and hide real issues.

  • Rewriting without protecting headings and entity coverage

    You improve readability but drop terms that drive rankings.

What Works

  • + Wider query coverage because more users can understand and keep reading.
  • + Cleaner snippets since key points are easier to extract from clear sentences.
  • + Better internal linking performance because readers reach deeper sections and related pages.

What Doesn’t

  • - Pushing scores too high can remove needed terms and weaken relevance.
  • - Readability tools can misread lists, tables, and code blocks as “hard to read.”
  • - Fixing readability won’t save pages that miss intent or lack original info.

Expert Tip

Don’t “simplify” by removing entities and modifiers. Keep the technical nouns, then fix the glue words around them. Most readability gains come from shorter sentences, clearer verbs, and fewer stacked clauses, not from deleting important concepts.

Frequently Asked Questions

What readability score should I aim for in SEO?
In our dataset, 40–60 drove the most impressions. Treat it as a target band, not a rule.
Does Google rank pages higher because they are easier to read?
Our data shows a strong correlation with visibility. The safest takeaway is that clearer pages earn more impressions.
Can technical content rank well with low readability?
Yes, if the query demands technical depth. Add summaries and definitions to lift impressions without removing detail.
Is readability more important than backlinks?
No single factor replaces authority. Readability is a scaling factor for impressions once you meet intent and quality.
Does keyword density improve readability scores and rankings?
No, it often hurts readability. Stuffing repeats makes text harder to scan and can cut impressions.
