kocos.com website review

16 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.1 s.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 400 ms).

6 images could be 239 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 55 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.

5 third-party services load with your homepage (clickskeks.at, Bing Ads and ahrefs.com and others), adding 277 KiB and 136 ms of main-thread time.

Polyfills for old browsers add 7 KiB JavaScript that modern phones do not need.

6 KiB could be saved by minifying CSS.

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 (2 KiB).

Your largest element takes 2.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Electrical and Optical Metrology”. Most of its time is element render delay (1.4 s).

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.

5 images (347 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 0.26 g of CO₂e: 31.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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.

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

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

The homepage links to 80 pages on kocos.com and 5 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.kocos.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.kocos.com/home, https://www.kocos.com/us/home and https://www.kocos.com/ar/%D9%84%D8%B1%D8%A6%D9%8A%D8%B3%D9%8A%D8%A9 all use the title “KoCoS - Your No. 1 for Electrical and Optical Metrology”. Search engines can't tell which page to show for a search, so each competes with the others.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://www.kocos.com/us/home, whose canonical is https://www.kocos.com/home. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://www.kocos.com/ar/%D9%84%D8%B1%D8%A6%D9%8A%D8%B3%D9%8A%D8%A9 has 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 15 pages linked from your homepage (of 43 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.net/action/0?ti=97180129&Ver=2&mid=386e2abf-36ff-4e89-bfec-c4978b49b0a3&bo=2&pi=918639831&lg=en-US&sw=390&sh=844&sc=24&nwd=1&tl=KoCoS%20-%20Your%20No.%201%20for%20Electrical%20and%20O.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

2 images are displayed at the wrong aspect ratio, so they look 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 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 518 words of visible text.

Before a visitor clicks anything, the page loads Google Tag Manager and Microsoft Ads (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.

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