What the Data Shows

Pages with CWV scores of 20-40 get the most impressions. The spread is ~56%. Content-rich pages may score lower on CWV but still attract more visibility.

Bottom line: CWV affects rankings, but visibility can peak at mid scores when pages are content-heavy.

How to Read This Chart

The x-axis shows Core Web Vitals performance score buckets. Each bar shows relative impressions for pages in that bucket. Notice the peak in the 20–40 bucket and the ~56% spread across buckets. High scores do not automatically mean the most visibility.

Background

Many SEOs treat Core Web Vitals as a tie-breaker. Others ignore it because “content wins anyway.” We bucketed 35K+ pages by CWV performance score and compared relative impressions. The relationship is real, but not linear. The 20–40 score bucket gets the most impressions, with a ~56% spread across buckets.

What to Do Next

  1. 1

    Export top 100 landing pages by impressions and map CWV score buckets high

    Pick the worst bucket among your best pages and start there.

  2. 2

    Split CWV by template and device in Search Console high

    Find the one template causing most “poor” URLs on mobile.

  3. 3

    Remove or delay one heavy 3rd‑party script on the top template medium

    Re-test INP and LCP after each removal to confirm impact.

  4. 4

    Preload the LCP element and compress the hero asset medium

    Ship one change and validate in field data over the next weeks.

Best Practices

  1. 1

    Pass CWV on top landing pages (LCP < 2.5s, INP < 200ms, CLS < 0.1)

    Fix the pages that already earn demand. If you don’t, you cap growth and lose close calls on competitive queries.

  2. 2

    Cut 3rd‑party JS to < 200 KB on templates

    Third-party scripts are a common INP killer. If you keep them, you will not hold “good” CWV at scale.

  3. 3

    Keep hero images < 200 KB and preload the LCP asset

    This lowers LCP on real devices. If you don’t, mobile scores stay stuck even after other fixes.

  4. 4

    Target a stable 50–70 score, not 90+

    Mid scores can still win when content is strong. Chasing 90+ often means stripping useful modules that earn links and long-tail traffic.

Common Mistakes to Avoid

  • Chasing a 100 performance score across the whole site

    You waste time on pages that will never drive impressions.

  • Using only lab scores and ignoring field data

    You “fix” CWV and see no change because real-user bottlenecks remain.

  • Blaming CWV for every ranking drop

    You miss content and intent issues that move impressions far more.

What Works

  • + Fewer slow loads reduce short clicks and back-to-SERP behavior.
  • + Faster rendering improves crawl efficiency on heavy template sites.
  • + Better INP reduces interaction friction on ads, filters, and nav.

What Doesn’t

  • - Chasing the score can remove content blocks that drive impressions.
  • - Lab scores swing by device and test location, so wins look bigger than they are.
  • - Fixing CWV on low-demand pages rarely changes total impressions.

Expert Tip

Treat CWV as a page-type constraint, not a site-wide KPI. Content hubs often sit in the 20–40 range because of widgets, tables, and embeds. Fix the one bottleneck that hits field CWV (often INP from 3rd-party JS), and keep the content that earns the impressions.

Frequently Asked Questions

Does Core Web Vitals performance score affect Google rankings?
Yes. Our page-level buckets show clear differences in impressions across CWV score ranges.
What CWV performance score should I aim for?
Aim for “good” CWV in field data on your top pages. For scores, push toward a stable 50–70 before chasing higher.
If CWV affects rankings, why do 20–40 score pages get the most impressions?
Because content-heavy pages match more queries and earn more long-tail impressions. CWV still matters, but content can outweigh it.
Will improving CWV move rankings fast?
Sometimes, but not always. It tends to help most in tight SERPs where relevance is similar.
Is a 90+ PageSpeed score required to rank?
No. Many pages rank with mid scores, especially when they cover topics deeply and satisfy intent.
