siruishop.de website review

About 1.5 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 8.9 s faster on a phone.

The page goes through 2 redirects before it starts loading, costing about 8.9 s. Link and advertise the final URL directly.

A phone's processor spends 10.1 s on main-thread work while loading, 6.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 32. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google Tag Manager, gsitrix.com and omnisnippet1.com and others), adding 3.4 MB and 2.3 s of main-thread time.

25 files are served with short cache lifetimes, so returning visitors download them again (698 KiB).

Google Tag Manager costs a phone 917 ms of main-thread work and 1.5 MB 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.

20 long tasks block the main thread while loading, the longest for 543 ms. During a long task the page ignores taps.

gsitrix.com costs a phone 497 ms of main-thread work and 60 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.

The page has 2,658 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Google/Doubleclick Ads costs a phone 190 ms of main-thread work and 496 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.

Shopify costs a phone 123 ms of main-thread work and 474 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.

xcottons.com costs a phone 112 ms of main-thread work and 365 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.

The HTML itself could arrive about 250 ms sooner: redirects, a slow server response or missing compression delay everything after it.

12 images could be 193 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 150 ms.

Polyfills for old browsers add 100 KiB JavaScript that modern phones do not need.

9 KiB could be saved by minifying JavaScript.

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

5 KiB JavaScript is shipped twice across bundles.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Your largest element takes 21.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 36.8 s. Good is under 3.8 s.

Scripts block taps and scrolling for 1.7 s in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 9.4 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 97 ms to 179 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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

Your homepage downloads 57.5 MB in 481 requests on a phone: media 50.7 MB (6), scripts 4.1 MB (180) and other files 1.1 MB (168). Under 2 MB keeps phones on slow connections fast.

750x1000-1.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).

1 image (72 KiB) is 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 16.30 g of CO₂e: 1955.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

8 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

5 tap targets are too small or too close together to hit reliably with a finger.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

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

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Headings should not be empty: 6 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.

Your meta description is 239 characters; Google truncates after about 160, so the end of your pitch is cut.

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

Your <h1> is empty.

The homepage links to 213 pages on siruishop.de and 14 external pages.

https://siruishop.de/collections/nach-serien-einkaufen has no meta description, so Google writes the search snippet from whatever text it finds.

https://siruishop.de/products/sirui-swift-20mm-40mm-vollformat-autofokus-objektiv, https://siruishop.de/products/saturn-v2-serie-anamorphotes-vollformat-cine-objektiv, https://siruishop.de/collections/objektiv, https://siruishop.de/collections/nach-serien-einkaufen, https://siruishop.de/products/sirui-saturn-35-50-75mm-t2-9-1-6x-anamorphotes-carbon-vollformat-objektiv-for-diverse-kameraanschlosse and https://siruishop.de/products/night-walker-t1-2-s35-cine-lens-series and 7 others have no <h1> headline, so visitors and search engines get no clear main topic.

https://siruishop.de/products/sirui-swift-20mm-40mm-vollformat-autofokus-objektiv and https://siruishop.de/products/sirui-ironstar-1-5x-anamorphic-cine-lens-series 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.

https://siruishop.de/pages/exklusive-angebote took over 3 s to send its HTML from our server.

We fetched 15 pages linked from your homepage (of 120 found) and read each the way a search engine does.

The page uses 1 deprecated browser API that will stop working in future browsers (“Synchronous `XMLHttpRequest` on the main thread is deprecated because of its detrimental effects to…”).

3 errors were logged to the browser console while the page loaded, for example “SyntaxError: Failed to execute 'querySelector' on 'Document': '[class*=' is not a valid selector.”.

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

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

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

The homepage carries about 507 words of visible text.

Opening the homepage sets 25 cookies, 2 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 44 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
