Competitor Comparison

Competitors: Free 2 · Solo 3 · Agency 5 · Scale 10

Field data (real Chrome user measurements) for the whole domain, all devices combined, over the last 28 days. That is why these values can differ from the per-page mobile and desktop figures above. Comparing at domain level keeps the table readable with several competitors. How we measure

Your values against your industry

Where this domain sits in the Online retail distribution, measured across 1034 domains. The colour of your own value still follows the Google thresholds.

Metric	Your domain	Industry median	Middle half of the industry	Position
LCP	5084 ms	1992 ms	1534 ms – 2602 ms	Slowest quarter
INP	384 ms	185 ms	137 ms – 253 ms	Slowest quarter
CLS	0.21	0.05	0.01 – 0.13	Slowest quarter

Google keeps the same pass thresholds for every site: 2500 ms LCP, 200 ms INP, 0.1 CLS. The industry values say what is common, not what is good.

CrUX Trend for this Domain

Real Chrome user data for the whole domain, all devices combined, week by week. Each point covers the 28 days up to that week, so the latest point can differ slightly from the competitor comparison. The dot colour shows how that week rates, the dashed lines mark the thresholds for good and poor. Google currently provides up to six months of history, not a limitation of this tool. How we measure

1. Reduce unused JavaScript est. -890 ms

Mobile All 10 analyzed pages

Several scripts ship more code than the page actually executes, delaying interactivity on mobile.

Code-split routes and defer non-critical bundles so only the JavaScript needed for the first render loads eagerly.

Guide

Affected files

vendor-bundle.min.js · saves up to ≈ 856 ms / 209 KB
analytics-suite.js · saves up to ≈ 232 ms / 57 KB

2. Lazy-load offscreen images est. -640 ms

Mobile and Desktop /blog, /blog/core-web-vitals-guide, /blog/image-optimization-responsive-images-srcset-avif-webp-lazy-loading-guide, /features

Images below the fold load immediately, competing with the largest contentful paint image for bandwidth.

Add loading="lazy" to below-the-fold images and prioritize only the hero image.

Guide

Affected files

post-hero-wide.jpg · saves up to ≈ 1.2 s / 305 KB

3. Serve images in modern formats est. -720 ms

Mobile and Desktop /, /features, /integrations, /blog, /blog/core-web-vitals-guide, /blog/image-optimization-responsive-images-srcset-avif-webp-lazy-loading-guide, /pricing

Product screenshots and marketing photos are shipped as unoptimized JPEG/PNG, far larger than a modern WebP/AVIF encode.

Re-encode images as WebP or AVIF with a JPEG/PNG fallback for older browsers.

Guide

Affected files

hero-dashboard.png · saves up to ≈ 1.1 s / 262 KB
pricing-comparison.png · saves up to ≈ 536 ms / 131 KB

4. Eliminate render-blocking resources est. -410 ms

Mobile and Desktop All 10 analyzed pages

The stylesheet and several scripts in the document head block the first paint on every page.

Inline critical CSS, defer the rest, and load non-essential scripts with the defer attribute.

Guide

Affected files

app.css · saves up to 310 ms / ≈ 24 KB
main.js · saves up to 100 ms / ≈ 8 KB

5. Minify JavaScript est. -320 ms

Mobile All 10 analyzed pages

The main application bundle and several third-party scripts ship unminified, with comments and whitespace intact.

Run a production build step (minification + tree-shaking) before deploying JavaScript bundles.

Guide

Affected files

main.js · saves up to ≈ 164 ms / 40 KB

6. Enable text compression est. -280 ms

Mobile and Desktop All 10 analyzed pages

HTML, CSS and JavaScript responses are served without gzip or Brotli compression.

Enable Brotli (or gzip as a fallback) compression for all text-based responses at the web server or CDN level.

Guide

7. Preconnect to required origins est. -150 ms

Mobile All 10 analyzed pages

Third-party origins for fonts, analytics and the live-chat widget are discovered late, adding avoidable connection latency.

Add <link rel="preconnect"> for the font, analytics and chat-widget origins used on every page.

Guide

8. Prioritize the LCP image est. -260 ms

Mobile and Desktop /, /features, /integrations, /blog/core-web-vitals-guide

The largest contentful paint element is a hero image that is not marked as a high-priority resource.

Add fetchpriority="high" and preload the hero image so it starts downloading immediately.

Lab Metrics

Controlled measurements from a single Lighthouse run per page. Useful for finding the cause of a slow page, but values can vary a little between runs.

Test setup: mobile emulates a mid-range phone on a throttled connection, desktop runs unemulated on a faster connection. Both run in headless Chrome.

Breakdown by asset type for each analyzed page (mobile). Weight can vary a lot page to page, so an average would be misleading here.

Compare all third parties in the benchmark

Monitoring, team, API and other account features in the Scale plan

These features belong to your account rather than a single report, so they do not appear above. Each card shows the plan it starts in.

Monitoring

Monitoring every 6 hours, daily or weekly, device of your choice, 12,000 PageSpeed tests per month for monitoring, manual scans, MCP and REST API (one per URL and device)

PerfDelta measures your URLs automatically, emails you when values get worse and sends a weekly performance report.

Available from Solo PageSpeed tests per month: Free 0 · Solo 600 · Agency 4000 · Scale 12000

Manual PageSpeed tests per day

Up to 2,400 PageSpeed tests per day for manual scans in the web app, via MCP and REST API, from the monthly budget

Manual scans in the web app, via MCP and the REST API draw on the monthly budget you share with monitoring, one PageSpeed test per URL and device. A daily cap protects against spikes.

Manual PageSpeed tests per day: Free 6 · Solo 120 · Agency 800 · Scale 2400

Projects, tags and status dashboard

Keep several clients or sites apart in their own projects, filter monitored URLs by tag and share a public status page.
