supertexinternational.com website review

11 files are served with short cache lifetimes, so returning visitors download them again (405 KiB).

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 1.9 s).

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.9 s.

Your mobile performance score is 57. Pages that score under 90 lose visitors before the first paint.

About 138 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 720 ms faster on a phone.

The page goes through 1 redirect before it starts loading, costing about 751 ms. Link and advertise the final URL directly.

About 87 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

1 image could be 26 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

14 KiB could be saved by minifying JavaScript.

The HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.

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

Visually, the page fills in at 9.9 s (Speed Index). Good is under 3.4 s.

The layout shifts by 0.364 while loading, so content jumps under the reader's thumb. Good is under 0.1.

The first text or image appears after 3.5 s on a phone. Good is under 1.8 s.

Your largest element takes 3.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image. Most of its time is resource load delay (2.4 s).

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

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

By the Sustainable Web Design model, a visit to your homepage emits about 0.12 g of CO₂e: 14.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

<html> element must have a lang attribute: 1 element on the page fails this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 5 elements on the page fail this check, rated moderate by axe-core.

3 form fields have no label, so screen readers announce an empty box and autofill guesses.

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

The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.

Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

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

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your title is only 8 characters: “SUPERTEX”. 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 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.

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

There is no robots.txt at supertexinternational.com/robots.txt, the first file search crawlers ask for.

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

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

The homepage links to 12 pages on supertexinternational.com and 3 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 https://www.supertexinternational.com/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.

/, https://www.supertexinternational.com/Supertex/index, https://www.supertexinternational.com/Supertex/about, https://www.supertexinternational.com/Supertex/category, https://www.supertexinternational.com/Supertex/functional and https://www.supertexinternational.com/Supertex/sfw and 3 others all use the title “SUPERTEX”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.supertexinternational.com/Supertex/index, https://www.supertexinternational.com/Supertex/about, https://www.supertexinternational.com/Supertex/category, https://www.supertexinternational.com/Supertex/functional, https://www.supertexinternational.com/Supertex/sfw and https://www.supertexinternational.com/Supertex/qc and 3 others have no <h1> headline, so visitors and search engines get no clear main topic.

https://www.supertexinternational.com/Supertex/category, https://www.supertexinternational.com/supertex/partner and https://www.supertexinternational.com/Supertex/contact have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 9 pages linked from your homepage and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 (Not Found)”.

The page has no <!DOCTYPE html>, so browsers render it in quirks mode.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

2 images are served at too low a resolution for sharp phone screens.

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

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage has only about 1 words of visible text; thin pages give Google and first-time buyers little to go on.

There is no form on the homepage, so every lead has to click through to another page first.

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

Opening the homepage sets 1 cookie (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.
