Confirmed Based on 22,840 data points

What the Data Shows

Pages with 60-80 accessibility scores get the most impressions. The spread is ~36% between the best and worst buckets.

Bottom line: Better accessibility scores correlate with more impressions, with a ~36% gap across buckets.

How to Read This Chart

The x-axis groups pages into accessibility score buckets. Each bar shows relative impressions for that bucket. Look for the tallest bar to see the best-performing range and the drop to the weakest bucket.

Background

Many SEOs treat accessibility as a legal or UX task. They assume it has no search impact. Our data says otherwise. We compared 22K+ unique pages by accessibility score buckets and relative impressions, and saw a clear lift in the top bucket range.

What to Do Next

  1. 1

    Run an accessibility crawl on top templates high

    Audit home, category, product, and article templates, not random URLs.

  2. 2

    Fix the top 10 repeat errors site-wide high

    Start with alt text, form labels, contrast, and heading order.

  3. 3

    Ship changes behind a small rollout medium

    Roll out to 5–10% of pages and watch impressions and engagement for two weeks.

  4. 4

    Add an accessibility check to QA low

    Fail builds when critical issues return on key templates.

Best Practices

  1. 1

    Fix missing alt text (0 critical images)

    Alt text helps search and screen readers understand images. Missing alt often means weaker relevance signals.

  2. 2

    Add labels to inputs (100% labeled fields)

    Labeled forms reduce friction and help assistive tech. Unlabeled fields can break key user actions and hurt engagement.

  3. 3

    Meet contrast checks (AA on key templates)

    Good contrast improves readability and reduces pogo-sticking. Poor contrast pushes users away fast on mobile.

  4. 4

    Keep heading order clean (one H1, no skips)

    Clean headings make page structure clear for users and crawlers. Skipped levels often signal messy templates and weak information order.

Common Mistakes to Avoid

  • Chasing a 100 score

    You burn dev time for tiny gains while missing high-impact fixes.

  • Using accessibility overlays

    They can add bloat, conflicts, and a false sense of compliance.

  • Auditing one page type only

    Template-wide issues stay live across thousands of URLs.

What Works

  • + Cleaner HTML structure makes it easier for crawlers to parse page sections.
  • + Better readability and forms reduce bounce and increase successful sessions.
  • + Fewer hidden blockers like unlabeled controls improves interaction on mobile and assistive tech.

What Doesn’t

  • - Accessibility scores can rise from cosmetic tweaks that do not change content relevance.
  • - Overlays and extra scripts can slow pages and add rendering issues.
  • - One-off fixes on a single URL do not move site-wide visibility.

Expert Tip

Treat accessibility score as a proxy for template quality. The biggest SEO wins usually come from fixing repeated template errors, not polishing edge-case warnings on a few pages.

Frequently Asked Questions

Does an accessibility score directly affect Google rankings?
It is not a single ranking factor you can tune. But it tracks with things Google rewards, like usable pages.
What accessibility score range gets the most impressions?
In our dataset, the 60–80 bucket had the highest relative impressions.
Is accessibility just a UX issue, not an SEO issue?
No. The same problems that block users also block crawling, parsing, and conversion paths.
Should I stop at 60–80 instead of trying to hit 90+?
Do the biggest fixes first. After that, test ROI, because some points are low impact.
Can improving accessibility hurt SEO?
Yes, if you add heavy scripts or change templates without QA. Keep changes lean and measure before and after.
