Does page health score predict search performance?

It Depends

What the Data Shows

Not enough data to draw a strong conclusion on health score and search performance.

Bottom line: Use health score to find fixes, not to forecast impressions or CTR.

How to Read This Chart

The X-axis shows health score buckets from low to high. Each bucket has two bars for relative impressions and relative CTR. If health score predicted performance, you would see both bars rise steadily across buckets. Instead, the bars jump around, so the relationship is not strong.

Background

Teams love a single “page health score.” It feels like an easy proxy for rankings and traffic. We bucketed millions of pages by health score and compared relative impressions and CTR. The pattern was weak and noisy, so we cannot claim health score predicts search performance.

What to Do Next

  1. 1

    Split health score by template and directory high

    Compare impressions and CTR inside each template to avoid mixed signals.

  2. 2

    Create a “blockers” segment and fix it this week high

    Group pages with noindex, bad canonicals, 4xx/5xx, and redirect chains, then clear them.

  3. 3

    Run a before/after check on one fix medium

    Pick one change and measure delta in crawl stats, impressions, and CTR after 14–28 days.

  4. 4

    Replace the single KPI with three metrics low

    Track index coverage, crawl hits, and duplicate rate alongside the score.

Best Practices

  1. 1

    Fix index coverage errors first (0 critical)

    Pages that cannot index cannot earn impressions. If you chase score points instead, you may ignore pages stuck in “Crawled - currently not indexed.”

  2. 2

    Keep TTFB under 800ms on key templates

    Slow responses cut crawl efficiency and hurt UX. If TTFB stays high, crawlers hit fewer URLs per visit and logs show wasted budget.

  3. 3

    Hold CLS under 0.1 on top landing pages

    Layout shift steals clicks and drops on-page engagement. If CLS is high, CTR may not fall, but conversion often does.

  4. 4

    Reduce duplicate titles below 1% per section

    Duplicate titles blur intent and hurt snippet match. If you ignore it, pages compete and impressions spread thin across near-duplicates.

Common Mistakes to Avoid

  • Using the score as a KPI for organic growth

    You can raise the score and still lose impressions due to intent mismatch or weak pages.

  • Averaging health across the whole site

    A few huge directories can hide failing revenue pages in the same score bucket.

  • Fixing low-impact warnings to “green” the report

    You spend weeks on tiny wins while indexability, internal links, and content gaps stay unfixed.

What Works

  • + Finds index blockers and broken canonicals fast.
  • + Flags template-wide issues that can hit thousands of URLs at once.
  • + Reduces crawl waste by surfacing thin or duplicate URL patterns.

What Doesn’t

  • - Blends many signals into one number, so root cause stays hidden.
  • - Can reward “easy” fixes that do not change impressions or CTR.
  • - Site averages can mask the pages that actually drive revenue.

Expert Tip

Health scores often suffer from Simpson’s paradox. A “better” bucket can contain more low-demand pages, while a “worse” bucket contains your highest-demand pages. Always test score vs impressions within the same template, query type, and country.

Frequently Asked Questions

Does a higher page health score mean higher rankings?
Not reliably. Our buckets did not show a clear lift in impressions or CTR as scores rose.
Why do low-health pages sometimes get more impressions?
They can rank because they match demand, have links, or sit in strong templates. Health issues may not block indexing or relevance.
Should I stop tracking health scores?
No. Track it for QA and risk control, not as a traffic forecast.
What parts of “health” matter most for search?
Indexing, crawl paths, and duplicate control tend to matter most. Speed and CWV matter more when they are very bad.
If health score does not predict performance, is it useless?
No. It is great for finding broken pages and regressions, but it is not a ranking model.
