4startech.com website review

About 464 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.1 s faster on a phone.

6 images could be 279 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.1 s faster on a phone.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.3 s.

Your mobile performance score is 48. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google Tag Manager, Bigcommerce and skylitech.com and others), adding 1.9 MB and 1.1 s of main-thread time.

About 91 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 750 ms faster on a phone.

Google Tag Manager costs a phone 464 ms of main-thread work and 560 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.

Bigcommerce costs a phone 395 ms of main-thread work and 876 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.

12 long tasks block the main thread while loading, the longest for 437 ms. During a long task the page ignores taps.

38 KiB JavaScript is shipped twice across bundles. Google estimates it would make the page about 300 ms faster on a phone.

A phone's processor spends 3.0 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 2,370 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

LiveChat costs a phone 94 ms of main-thread work and 366 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.

26 KiB could be saved by minifying CSS.

Polyfills for old browsers add 14 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

11 files are served with short cache lifetimes, so returning visitors download them again (55 KiB).

21 KiB could be saved by minifying JavaScript.

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 11.6 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 12.9 s. Good is under 3.8 s.

Scripts block taps and scrolling for 697 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.

For real visitors the layout shifts by 0.18 (75th percentile). Good is under 0.1.

Real visitors see the first content after 2.0 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.2 s for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 5.5 s (Speed Index). Good is under 3.4 s.

4 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' largest content (lcp) went from 2.7 s to 2.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

4ST_BC_Carousel_Backdrop_2.jpg 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).

1 image further down the page (33 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.55 g of CO₂e: 65.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Form elements must have labels: 2 elements on the page fail this check, rated critical by axe-core.

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

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

5 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: 21 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 visible link has no text or label, so screen readers cannot say where it goes.

Headings skip levels (h1 → h3 and h2 → h4), which makes the page harder to scan with a screen reader.

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

There are 4 <h1> headlines (“Four Star Networking Equipment At Four Star Value”, “Large selection of New and Refurbished” and “Offering Aruba & Instant On”). One clear main headline is easier for people and search engines.

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://4startech.com/sitemap.xml, so Google discovers your pages only by following links.

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

The homepage links to 412 pages on 4startech.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.

/terms-conditions, /product-guaranty, /product-inquiry, /brocade, /brocade/icx-switch-fans-1 and /brocade/icx-switch-icx-6400-series-1 and 5 others have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example /rfq-contact-form, whose canonical is /buy-back-program. 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 197 found) and read each the way a search engine does.

4 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

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

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.

4startech.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.

4startech.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.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

Social proof on the homepage: 1 testimonial or review block. Pairing it with named testimonials or customer logos makes it far more convincing.

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 439 words of visible text.

DMARC is set to p=none, so mail pretending to be 4startech.com is still delivered. Add a report address, check the reports, then move to quarantine.

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 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 21 cookies, 4 of them by other companies (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 18 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
