chemcore.com website review

Your mobile performance score is 46. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.3 s on main-thread work while loading, 744 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

9 long tasks block the main thread while loading, the longest for 395 ms. During a long task the page ignores taps.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 350 ms.

The page has 2,096 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

About 29 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

About 28 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

2 third-party services load with your homepage (Shopify and shop.app), adding 194 KiB and 90 ms of main-thread time.

2 images could be 90 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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.

1 file is served with short cache lifetimes, so returning visitors download them again (1 KiB).

Your largest element takes 25.8 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 27.9 s. Good is under 3.8 s.

The layout shifts by 0.367 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Visually, the page fills in at 6.1 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.5 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 84 ms to 79 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 10.5 MB in 292 requests on a phone: images 8.7 MB (18), other files 1.1 MB (207) and scripts 369 KiB (52). Under 2 MB keeps phones on slow connections fast.

4 images weigh 7.1 MB together. On a phone connection a single image that size takes seconds.

chemcore_logo_black_final.svg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 2.97 g of CO₂e: 355.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 buttons have no accessible name, so screen readers announce just “button”.

Scrollable region must have keyboard access: 2 elements on the page fail this check, rated serious by axe-core.

1 element hidden from screen readers can still receive keyboard focus.

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

All page content should be contained by landmarks: 4 elements on the page fail this check, rated moderate by axe-core.

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

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 19 characters: “Chemcore Industries”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

The homepage links to 162 pages on chemcore.com and 2 external pages.

Your homepage links to /collections/15-gauge-sinks and /collections/16-gauge-sinks, which answer with an error. Visitors hit a dead end and search engines drop them.

/collections/silgranit has no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 58 found) and read each the way a search engine does.

3 errors were logged to the browser console while the page loaded, for example “Refused to apply style from 'https://www.chemcore.com/cdn/shop/t/2/assets/tiny.content.min.css?v=637' because its MIME …”.

2 links from your homepage to your own site are broken, for example https://www.chemcore.com/collections/farmhouse-sinks (network).

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

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.

chemcore.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.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

Social proof on the homepage: 6 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

The homepage has only about 168 words of visible text; thin pages give Google and first-time buyers little to go on.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

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.

Opening the homepage sets 5 cookies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
