Have questions?

Speed Layer helps optimize page performance and loading order. Results vary by site, device and network conditions.

Faster websites can improve the shopping experience. Our GA4 comparisons found differences in engagement and configured conversion events per session. Those observational differences do not establish causal lift.

Quicker access to content and products can support shopping. Our website and GA4 measurements do not establish sales or revenue gains.

After installation, we confirm activation and review page behavior. The time needed to measure results depends on traffic, configuration and the metric being evaluated.

Installation depends on your website configuration. We confirm setup and review page behavior with your team.

  • Source and period: Auto Genius fleetwide analysis dated October 2, 2026. June 5–October 2; PageSpeed through October 2, field and GA4 through September 30.
  • Coverage: 526 sites: 489 licensed and 37 trial. Eligible sites: PageSpeed 494, field LCP 233, GA4 313. Device subsets overlap.
  • PageSpeed: Matched Active/Control site/day/device tests; at least 14 paired days. Equal weighting of eligible site/device means. The relative score lift does not mean the site is that percentage faster.
  • Field LCP: Matched Active/Control site/device/days; at least 100 samples per group per day and seven paired days. Equal weighting of site/device mean daily p75 values, not a pooled fleet percentile.
  • GA4 comparison: Matched site/date/device/property pairs; at least 14 paired days and 100 sessions per group. Inconsistent or empty groups excluded. Non-Active is derived as Total minus Active, not an independently observed randomized control.
  • GA4 rates: Engaged sessions per session were 18.2% higher across 313 eligible sites. Configured ASC conversion events per session were 34.6% higher. Relative differences use each group’s corresponding session denominator. Observational results do not establish causality, unique customers, sales or revenue.
  • Limits: Results vary. Trial mobile field LCP was 1.22% higher, or slower, across 18 eligible sites. These results do not guarantee an improvement on every site or every Core Web Vital.
