Chrome UX Report (opens in a new tab): real Chrome visitors over rolling 28-day periods.
One score from every part of this review. How it works
Speed
Render-blocking requests
550 ms2 files block the first paint until they finish downloading. Deferring or inlining them could save about 550 ms.
Improve image delivery
112 KiB3 images could be 112 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.
6 third-party services on the page
6 third-party services load with your homepage (Shopify, Bugsnag and zi-scripts.com and others), adding 109 KiB and 32 ms of main-thread time.
Use efficient cache lifetimes
36 KiB4 files are served with short cache lifetimes, so returning visitors download them again (36 KiB).
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.
Forced reflow
Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.
Minify CSS
3 KiB3 KiB could be saved by minifying CSS.

Images and page weight
About 0.4 g of CO₂ per visit
0.36 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.36 g of CO₂e: 43.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
4 checks passed
Page weight: 1.3 MB in 117 requests
1.3 MBYour homepage downloads 1.3 MB in 117 requests on a phone: other files 663 KiB (69), images 248 KiB (6) and scripts 217 KiB (30). That is a lean page.
Images use modern formats
Every sizeable image is WebP, AVIF or SVG.
Images load when needed
Images below the first screen wait until the visitor scrolls to them.
Images are sized for phones
No image is downloaded at more than three times the size it is drawn on a phone.
Accessibility
Certain ARIA roles must contain particular children (1 element)
Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.
2 text elements with low contrast
2 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
Orphan list items
Some list items are not inside a list.
All page content should be contained by landmarks (1 element)
All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.
2 checks passed
Every image has alt text

47 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 51 WCAG 2.2 A/AA and best-practice rules on the phone render: 47 passed and 4 failed. 2 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
3 H1 headlines
There are 3 <h1> headlines (“”, “” and “The part you qualified. Every build.”). One clear main headline is easier for people and search engines.
No social preview image
No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.
57 internal links, 0 external
The homepage links to 57 pages on centon.com and 0 external pages.

AI search readiness
4 checks passed
AI answer engines may read the site
Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.
Organization data: 4 of 6 facts
Your Organization JSON-LD gives name, url, logo and contact details; sameAs (social profiles) and description would complete it.
Text is in the HTML
Your server sends the page's text in the HTML (430 words), so crawlers that don't run JavaScript still read it.
llms.txt published
The site publishes https://www.centon.com/llms.txt (6 KiB, 8 links), a plain-text guide to the site for AI tools.
Other pages
2 pages share a title
https://www.centon.com/collections/taa and https://www.centon.com/collections/professional-taa all use the title “TAA Compliant USB & microSD, Professional Series | Centon”. Search engines can't tell which page to show for a search, so each competes with the others.
2 pages share a meta description
https://www.centon.com/collections/taa and https://www.centon.com/collections/professional-taa use the same meta description. A description written for each page earns more clicks.
1 link to non-canonical URLs
Your homepage links to 1 page by a URL that isn't its canonical one, for example https://www.centon.com/collections/professional-taa, whose canonical is https://www.centon.com/collections/taa. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.
