quantumstorage.com website review

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.4 s.

About 210 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.1 s faster on a phone.

Your mobile performance score is 44 (desktop: 92). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.5 s on main-thread work while loading, 2.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 119 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 740 ms faster on a phone.

2 third-party services load with your homepage (Google Tag Manager and Google Analytics), adding 304 KiB and 764 ms of main-thread time.

Google Tag Manager costs a phone 764 ms of main-thread work and 303 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.

188 KiB could be saved by minifying JavaScript.

18 long tasks block the main thread while loading, the longest for 537 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 150 ms).

6 images could be 96 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

13 KiB could be saved by minifying CSS.

Desktop scores 92 but mobile only 44. A gap that wide usually means heavy scripts and images that hit phones hardest.

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.

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 10.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 12.9 s. Good is under 3.8 s.

Visually, the page fills in at 7.3 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 779 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 3.2 s on a phone. Good is under 1.8 s.

Real visitors wait 2.5 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 1.1 s for your server to start answering (75th percentile). Good is under 800 ms.

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

3 images (104 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.52 g of CO₂e: 62.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

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

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

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

Headings skip levels (h1 → h3 and h1 → h3), which makes the page harder to scan with a screen reader.

Your title is 84 characters, so Google will cut it off around 60: “Plastic Storage Containers | Bin and Wire Shelving Systems - Quantum Storage Systems”.

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

There are 6 <h1> headlines (“BINS & SYSTEMS”, “WIRE SHELVING” and “STEEL SHELVING”). One clear main headline is easier for people and search engines.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

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

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

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

The homepage links to 120 pages on quantumstorage.com and 30 external pages.

Your robots.txt shuts out ChatGPT search (OAI-SearchBot), ChatGPT (ChatGPT-User) and Perplexity (PerplexityBot). These fetch pages to answer people's questions and cite the source, so your site can't be quoted or linked in those answers.

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.

robots.txt blocks GPTBot, ClaudeBot, Google-Extended, Applebot-Extended and CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers.

/catalogsearch/advanced, /bins-and-systems/mesh-stack-hang-bins and /bins-and-systems/all-purpose-plastic-storage-tubs use the same meta description. A description written for each page earns more clicks.

We fetched 15 pages linked from your homepage (of 101 found) and read each the way a search engine does.

15 of 48 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

On a 390 px-wide phone the page scrolls sideways, a sign that something is wider than the screen.

1 error was logged to the browser console while the page loaded, for example “Loading the script 'https://www.webtraxs.com/wt.php' violates the following Content Security Policy directive: "script-…”.

Chrome logged issues while loading the page (“Content security policy”).

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

The server only offers HTTP/1.1, so browsers open several connections and load files more slowly. Most hosts and CDNs turn on HTTP/2 with a setting.

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.

quantumstorage.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.

quantumstorage.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: 2 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

The homepage carries about 253 words of visible text.

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 Analytics and Google Tag Manager (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 13 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 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
