sheko.com website review

A phone's processor spends 8.7 s on main-thread work while loading, 3.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Other Google APIs/SDKs and Klaviyo and others), adding 1.6 MB and 1.6 s of main-thread time.

7 images could be 611 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 650 ms faster on a phone.

Your mobile performance score is 58. Pages that score under 90 lose visitors before the first paint.

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 750 ms.

30 files are served with short cache lifetimes, so returning visitors download them again (468 KiB).

About 450 KiB of JavaScript is downloaded but never used on this page.

Google Tag Manager costs a phone 394 ms of main-thread work and 369 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.

Other Google APIs/SDKs costs a phone 331 ms of main-thread work and 30 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.

Klaviyo costs a phone 245 ms of main-thread work and 371 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 2,275 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Shopify costs a phone 160 ms of main-thread work and 336 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.

12 long tasks block the main thread while loading, the longest for 228 ms. During a long task the page ignores taps.

Polyfills for old browsers add 94 KiB JavaScript that modern phones do not need.

About 10 KiB of CSS is downloaded but never applied on this page.

7 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.

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

2 KiB JavaScript is shipped twice across bundles.

Visually, the page fills in at 21.9 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 23.4 s. Good is under 3.8 s.

Your largest element takes 4.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “SHEKO 4 Wochen Starter Set Stracciatella Shake”.

Scripts block taps and scrolling for 572 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 177 ms to 169 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.3 s to 2.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.0 MB in 524 requests on a phone: scripts 2.1 MB (149), other files 1.7 MB (299) and images 902 KiB (27). Under 2 MB keeps phones on slow connections fast.

2 images (127 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 1.42 g of CO₂e: 170.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Summary elements must have discernible text: 1 element on the page fails this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 4 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.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

32 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.

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

There is no <h1>, so neither visitors nor Google get a clear main headline.

The homepage links to 140 pages on sheko.com and 16 external pages.

Your homepage links to /de-be, which answers with an error. Visitors hit a dead end and search engines drop it.

/customer_authentication/redirect has no <title>, so Google invents the link text in results.

/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

/pages/sheko-club and /customer_authentication/redirect have no meta description, so Google writes the search snippet from whatever text it finds.

/collections/abnehm-shakes, /pages/sheko-club, /blogs/guide, /blogs/rezepte and /customer_authentication/redirect have no <h1> headline, so visitors and search engines get no clear main topic.

/blogs/rezepte and /customer_authentication/redirect took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 60 found) and read each the way a search engine does.

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

4 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_SOCKET_NOT_CONNECTED”.

2 links from your homepage to your own site are broken, for example https://sheko.com/de-be/ (404).

1 link to other sites is dead, for example https://help.sheko.com/wie-hoch-sind-die-versandkosten-3617350 (404).

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

1 link go through two or more redirects, for example https://sheko.com/customer_authentication/redirect?locale=de&region_country=DE.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

sheko.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

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 phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach 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 378 words of visible text.

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

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Opening the homepage sets 32 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 62 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
