simuero.com website review

About 595 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.2 s faster on a phone.

26 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.3 s.

The page has 7,638 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 68. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (rebuyengine.com, Google Tag Manager and Clarity and others), adding 1.2 MB and 760 ms of main-thread time.

A phone's processor spends 3.2 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

rebuyengine.com costs a phone 267 ms of main-thread work and 331 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 91 ms of main-thread work and 316 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.

8 long tasks block the main thread while loading, the longest for 119 ms. During a long task the page ignores taps.

About 45 KiB of CSS is downloaded but never applied on this page.

7 files are served with short cache lifetimes, so returning visitors download them again (43 KiB).

Polyfills for old browsers add 36 KiB JavaScript that modern phones do not need.

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.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your homepage downloads 3.0 MB in 300 requests on a phone: scripts 1.3 MB (93), other files 873 KiB (129) and images 512 KiB (28). Under 2 MB keeps phones on slow connections fast.

5 images (244 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 0.84 g of CO₂e: 100.7 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”.

Images must have alternative text: 1 element on the page fails this check, rated critical by axe-core.

Some list items are not inside a list.

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

Scrollable region must have keyboard access: 16 elements on the page fail this check, rated serious by axe-core.

All page content should be contained by landmarks: 3 elements on the page fail this check, rated moderate by axe-core.

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

ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

Elements marked as presentational should be consistently ignored: 1 element on the page fails this check, rated minor by axe-core.

Elements with visible text labels do not have matching accessible names. (17 elements).

The homepage links to 225 pages on simuero.com and 9 external pages.

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

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

https://simuero.com/customer_authentication/redirect, https://simuero.com/policies/shipping-policy and https://simuero.com/collections/new-pieces have no meta description, so Google writes the search snippet from whatever text it finds.

https://simuero.com/collections/handmade-jewelry-shop, https://simuero.com/customer_authentication/redirect, https://simuero.com/policies/shipping-policy, https://simuero.com/collections/best-seller-jewelry, https://simuero.com/collections/new-pieces and https://simuero.com/collections/bags and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 51 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “TypeError: Cannot read properties of null (reading 'discountCodes')”.

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 testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust 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 280 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager, Klaviyo and Microsoft Clarity (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 7 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 28 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
