kottelab.com website review

18 images could be 537 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 800 ms faster on a phone.

Your mobile performance score is 72. Pages that score under 90 lose visitors before the first paint.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

Shopify costs a phone 145 ms of main-thread work and 353 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.

2 third-party services load with your homepage (Shopify and shop.app), adding 396 KiB and 158 ms of main-thread time.

About 43 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

About 35 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.

3 files are served with short cache lifetimes, so returning visitors download them again (12 KiB).

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.

Your largest element takes 8.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Gold spoons in a row filled with loose-leaf tea”.

The page becomes fully interactive after 9.0 s. Good is under 3.8 s.

The first text or image appears after 2.3 s on a phone. Good is under 1.8 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.

Your homepage downloads 2.4 MB in 164 requests on a phone: images 1.1 MB (25), other files 745 KiB (39) and scripts 393 KiB (86). Under 2 MB keeps phones on slow connections fast.

B0500408-4C34-4C9D-ABCC-E90E874F65AF_1_105_c.webp 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).

4 images (310 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 0.69 g of CO₂e: 82.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

Alternative text of images should not be repeated as text: 1 element on the page fails this check, rated minor by axe-core.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

5 links have no real href, so search engines can't follow them.

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

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

The homepage links to 97 pages on kottelab.com and 24 external pages.

https://kottelab.com/collections/all has no meta description, so Google writes the search snippet from whatever text it finds.

https://kottelab.com/collections/bobo4t has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 27 found) and read each the way a search engine does.

14 of 52 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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 ()”.

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.

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

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

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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 1,006 words of visible text.

Opening the homepage sets 5 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.
