the-sleeper.com website review

8 third-party services load with your homepage (Google Tag Manager, Klaviyo and TikTok and others), adding 1.3 MB and 1.2 s of main-thread time.

Your mobile performance score is 54. Pages that score under 90 lose visitors before the first paint.

10 files block the first paint until they finish downloading. Deferring or inlining them could save about 900 ms.

Google Tag Manager costs a phone 645 ms of main-thread work and 514 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 556 KiB of JavaScript is downloaded but never used on this page.

4 images could be 467 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

A phone's processor spends 3.6 s on main-thread work while loading, 1.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

7 long tasks block the main thread while loading, the longest for 262 ms. During a long task the page ignores taps.

Klaviyo costs a phone 170 ms of main-thread work and 305 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.

19 files are served with short cache lifetimes, so returning visitors download them again (178 KiB).

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

45 KiB could be saved by minifying JavaScript.

About 28 KiB of CSS is downloaded but never applied on this page.

Polyfills for old browsers add 27 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.

4 KiB could be saved by minifying CSS.

2 KiB JavaScript is shipped twice across bundles.

The page becomes fully interactive after 17.0 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.

Scripts block taps and scrolling for 685 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 5.1 s (Speed Index). Good is under 3.4 s.

The layout shifts by 0.178 while loading, so content jumps under the reader's thumb. Good is under 0.1.

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

Your homepage downloads 4.0 MB in 316 requests on a phone: scripts 1.7 MB (117), images 1.1 MB (28) and other files 845 KiB (131). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.13 g of CO₂e: 135.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Elements must only use permitted ARIA attributes: 1 element on the page fails this check, rated serious by axe-core.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

All page content should be contained by landmarks: 6 elements on the page fail this check, rated moderate by axe-core.

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

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

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

The homepage links to 106 pages on the-sleeper.com and 10 external pages.

Your homepage links to https://the-sleeper.com/apps/iwish, which answers with an error. Visitors hit a dead end and search engines drop it.

https://the-sleeper.com/collections/special-sale, https://the-sleeper.com/collections/iconic-pajamas-suit and https://the-sleeper.com/collections/knitwear have no meta description, so Google writes the search snippet from whatever text it finds.

https://the-sleeper.com/collections/shop-all, https://the-sleeper.com/collections/new-arrivals, https://the-sleeper.com/collections/best-sellers, https://the-sleeper.com/collections/bridal-edit, https://the-sleeper.com/collections/vacation and https://the-sleeper.com/collections/special-sale and 7 others have no <h1> headline, so visitors and search engines get no clear main topic.

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

6 errors were logged to the browser console while the page loaded, for example “Refused to apply style from 'https://the-sleeper.com/cdn/shop/t/132/assets/section-custom-liquid.css?v=33426' because i…”.

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 phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage has only about 40 words of visible text; thin pages give Google and first-time buyers little to go on.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.
