1st-chainsupply.com website review

About 236 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.2 s faster on a phone.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

Your mobile performance score is 60. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, Bigcommerce and Hotjar and others), adding 1.0 MB and 736 ms of main-thread time.

Google Tag Manager costs a phone 313 ms of main-thread work and 338 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 47 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

Bigcommerce costs a phone 262 ms of main-thread work and 563 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.

8 long tasks block the main thread while loading, the longest for 257 ms. During a long task the page ignores taps.

The page has 1,597 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

6 files are served with short cache lifetimes, so returning visitors download them again (27 KiB).

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

4 images could be 64 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 18 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.

5 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 8.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “QUANTITY DISCOUNTS ON ALL CHAINS SHOP ALL CHAINS”.

The page becomes fully interactive after 8.7 s. Good is under 3.8 s.

Real visitors wait 806 ms for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 489 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 3.8 s (Speed Index). Good is under 3.4 s.

16 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 79 ms to 69 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.0 s to 2.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

2 images (83 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

3 images further down the page (80 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 0.31 g of CO₂e: 37.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

37 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

All page content should be contained by landmarks: 43 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h2 → h6, h2 → h4 and h2 → h4), which makes the page harder to scan with a screen reader.

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

Your title is only 16 characters: “1st Chain Supply”. Between 30 and 65 characters leaves room to say what you do and for whom.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at https://www.1st-chainsupply.com/sitemap.xml, so Google discovers your pages only by following links.

1 link has no real href, so search engines can't follow it.

Your <h1> is empty.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 232 pages on 1st-chainsupply.com and 0 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no /llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

/chains, /chains/chain-by-type, /chain-by-type/binder-chain, /chain-by-type/mooring-chain, /chain-by-type/powder-coated and /chain-by-type/security-maxx and 8 others have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 2 pages by a URL that isn't their canonical one, for example /chain-by-type/powder-coated, whose canonical is /chains/chain-by-type/powder-coated. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 15 pages linked from your homepage (of 106 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=134612170&Ver=2&mid=1ed0fbbf-a7e9-4fa5-9e70-744c3175cb79&bo=1&sid=06817ab0d64a11f1880917c19b44a795&vid=06818600d64a11f1be7be5e5c8443af1&vids=1&msclkid=N&pi=918639831&l.

2 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

HSTS is set, but max-age is 0 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.

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

1st-chainsupply.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.

1st-chainsupply.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.

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

The homepage carries about 879 words of visible text.

1st-chainsupply.com has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

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 Google Ads, Google Analytics, Google Tag Manager, Hotjar and Klaviyo and 1 more (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 18 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 15 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
