koptergroup.com website review

94 files are served with short cache lifetimes, so returning visitors download them again (2.6 MB).

34 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.0 s.

Your mobile performance score is 64. Pages that score under 90 lose visitors before the first paint.

About 143 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 750 ms faster on a phone.

About 129 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.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 650 ms).

A phone's processor spends 2.5 s on main-thread work while loading, 874 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 long tasks block the main thread while loading, the longest for 224 ms. During a long task the page ignores taps.

Polyfills for old browsers add 14 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 200 ms faster on a phone.

2 images could be 146 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

3 third-party services load with your homepage (Google Tag Manager, Google Analytics and Google Fonts), adding 227 KiB and 115 ms of main-thread time.

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.

4 KiB could be saved by minifying JavaScript.

2 KiB could be saved by minifying CSS.

Your largest element takes 7.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Say hello to AW09! THE SWISS HELICOPTER”.

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

The page becomes fully interactive after 8.3 s. Good is under 3.8 s.

The first text or image appears after 2.4 s on a phone. Good is under 1.8 s.

6 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 88 ms to 88 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.9 MB in 99 requests on a phone: images 1.8 MB (18), scripts 478 KiB (39) and fonts 375 KiB (9). Under 2 MB keeps phones on slow connections fast.

4 images (196 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 0.81 g of CO₂e: 97.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

1 element hidden from screen readers can still receive keyboard focus.

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

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

Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.

Your title is 66 characters, so Google will cut it off around 60: “Say hello to AW09! A new generation of single turbine helicopters.”.

There are 2 <h1> headlines (“Say hello to AW09!” and “SINGLE [R]EVOLUTION”). One clear main headline is easier for people and search engines.

Your meta description is 164 characters; Google truncates after about 160, so the end of your pitch is cut.

13 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 59 pages on koptergroup.com and 12 external pages.

There is no https://koptergroup.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://koptergroup.com/2026/07, https://koptergroup.com/2026/05 and https://koptergroup.com/2026/04 declare the homepage as their canonical URL, which tells Google they are copies of the homepage and keeps them out of search results. A site-wide template setting usually causes this.

/, https://koptergroup.com/2026/07, https://koptergroup.com/2026/05 and https://koptergroup.com/2026/04 all use the title “Say hello to AW09! A new generation of single turbine helicopters.”. Search engines can't tell which page to show for a search, so each competes with the others.

https://koptergroup.com/2026/07, https://koptergroup.com/2026/05 and https://koptergroup.com/2026/04 use the same meta description. A description written for each page earns more clicks.

https://koptergroup.com/about, https://koptergroup.com/sh09-missions and https://koptergroup.com/contacts have no <h1> headline, so visitors and search engines get no clear main topic.

https://koptergroup.com/about, https://koptergroup.com/sh09-missions and https://koptergroup.com/services took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 20 found) and read each the way a search engine does.

27 of 54 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

3 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.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

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

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

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

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

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.

The homepage carries about 727 words of visible text.

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 2 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 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
