circulon.com website review

A phone's processor spends 4.2 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,763 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 67. Pages that score under 90 lose visitors before the first paint.

17 images could be 702 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 250 ms faster on a phone.

8 third-party services load with your homepage (Google Tag Manager, Clarity and Klaviyo and others), adding 907 KiB and 750 ms of main-thread time.

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 750 ms.

About 76 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

Google Tag Manager costs a phone 298 ms of main-thread work and 359 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

About 303 KiB of JavaScript is downloaded but never used on this page.

6 long tasks block the main thread while loading, the longest for 217 ms. During a long task the page ignores taps.

11 files are served with short cache lifetimes, so returning visitors download them again (69 KiB).

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

4 KiB could be saved by minifying JavaScript.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 13.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 24.1 s. Good is under 3.8 s.

Real visitors see the first content after 2.1 s (75th percentile). Good is under 1.8 s.

Real visitors wait 819 ms for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 4.6 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 220 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 175 ms to 185 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.6 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 7.1 MB in 424 requests on a phone: images 4.6 MB (74), scripts 1.3 MB (171) and other files 911 KiB (160). Under 2 MB keeps phones on slow connections fast.

6 images further down the page (395 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 2.00 g of CO₂e: 240.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

32 tap targets are too small or too close together to hit reliably with a finger.

18 elements hidden from screen readers can still receive keyboard focus.

Elements must only use permitted ARIA attributes: 5 elements on the page fail this check, rated serious by axe-core.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

9 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 15 elements on the page fail this check, rated moderate by axe-core.

19 visible links have no text or label, so screen readers cannot say where they go.

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 262 pages on circulon.com and 8 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

/pages/circulon-ceramic-with-laserdefense and /collections/circulon-ceramic-with-laserdefense all use the title “Circulon Ceramic with LaserDefense™”. Search engines can't tell which page to show for a search, so each competes with the others.

/pages/circulon-ceramic-with-laserdefense and /collections/circulon-ceramic-with-laserdefense use the same meta description. A description written for each page earns more clicks.

/pages/circulon-ceramic-with-laserdefense, /collections/a1-series, /collections/scratchdefense-clad-cookware, /collections/infinity-pan, /collections/circulon-ceramic-with-laserdefense and /collections/high-performance-nonstick-cookware and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 74 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=56263687&tm=gtm002&Ver=2&mid=2bf420b5-1e9a-4f84-8da1-c10a9e07d798&bo=1&sid=91503ea0dbfa11f1be76b1bcd6386267&vid=91503d20dbfa11f1a27b7f8edd107d39&vids=1&msclkid=N&pi=91.

6 errors were logged to the browser console while the page loaded, for example “Uncaught Bazaarvoice is not configured for the domain circulon.com.”.

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

3 links go through two or more redirects, for example https://circulon.com/account.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

circulon.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

circulon.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

The homepage carries about 482 words of visible text.

DMARC is set to p=none, so mail pretending to be circulon.com is still delivered. Reports are on, so moving to quarantine is the next step.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Amazon Ads, Google Ads, Google Analytics, Google Tag Manager and Klaviyo and 6 mores (measured from a US location before any click). A consent tool (Ketch) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 38 cookies, 1 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 61 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
