thejacketmaker.cz website review

About 1.4 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.4 s faster on a phone.

29 files are served with short cache lifetimes, so returning visitors download them again (480 KiB).

Shopify costs a phone 1.4 s of main-thread work and 1.1 MB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

A phone's processor spends 11.2 s on main-thread work while loading, 5.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 43. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

The page has 5,324 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Shopify, gotolstoy.com and Google Tag Manager and others), adding 3.3 MB and 3.1 s of main-thread time.

36 images could be 1.2 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 600 ms faster on a phone.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 950 ms.

130 KiB could be saved by minifying JavaScript.

gotolstoy.com costs a phone 576 ms of main-thread work and 405 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.

Google Tag Manager costs a phone 303 ms of main-thread work and 321 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.

rebuyengine.com costs a phone 255 ms of main-thread work and 715 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.

ZenDesk costs a phone 210 ms of main-thread work and 394 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.

About 52 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 270 ms faster on a phone.

20 long tasks block the main thread while loading, the longest for 218 ms. During a long task the page ignores taps.

Polyfills for old browsers add 48 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

7 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.

Your largest element takes 30.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

Visually, the page fills in at 20.1 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 41.5 s. Good is under 3.8 s.

Scripts block taps and scrolling for 963 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 151 ms to 196 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 2.2 s to 2.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 10.9 MB in 602 requests on a phone: images 5.7 MB (117), scripts 3.3 MB (164) and other files 1.1 MB (273). Under 2 MB keeps phones on slow connections fast.

32 images further down the page (3.4 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

10 images (1.1 MB) 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.

5 images are downloaded at several times the size a phone draws them, for example Mens_Leather_Shoes.webp at 1,000 px wide, shown at 179 px. Resized copies would save about 346 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 3.10 g of CO₂e: 372.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA attributes must conform to valid values: 3 elements on the page fail this check, rated critical by axe-core.

3 dropdowns have no label.

Interactive controls must not be nested: 1 element on the page fails this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 10 elements on the page fail this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

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

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

Headings should not be empty: 2 elements on the page fail this check, rated minor by axe-core.

There are 2 <h1> headlines (“” and “Create Your Custom Leather Jackets”). One clear main headline is easier for people and search engines.

Structured data found (BreadcrumbList, Organization and WebSite) but with 1 problem, for example “Organization: url points at a different host (https://www.thejacketmaker.com)”.

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

The homepage links to 304 pages on thejacketmaker.cz and 57 external pages.

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

https://www.thejacketmaker.cz/collections/all, https://www.thejacketmaker.cz/pages/black-friday-jacket-deals, https://www.thejacketmaker.cz/collections/mens-leather-jackets, https://www.thejacketmaker.cz/collections/mens-bomber-jackets, https://www.thejacketmaker.cz/collections/mens-aviator-jackets and https://www.thejacketmaker.cz/collections/mens-biker-leather-jackets and 7 others have no <h1> headline, so visitors and search engines get no clear main topic.

https://www.thejacketmaker.cz/collections/all, https://www.thejacketmaker.cz/collections/mens-leather-jackets, https://www.thejacketmaker.cz/collections/mens-bomber-jackets, https://www.thejacketmaker.cz/collections/mens-aviator-jackets, https://www.thejacketmaker.cz/collections/mens-biker-leather-jackets and https://www.thejacketmaker.cz/collections/mens-winter-jackets and 3 others 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 15 pages linked from your homepage (of 196 found) and read each the way a search engine does.

3 errors were logged to the browser console while the page loaded, for example “Error: ”.

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

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.

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

Your longest form asks for 10 fields (3 required). Every extra field lowers completion.

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

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.

The homepage carries about 1,993 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel (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 28 cookies, 1 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 48 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
