swimessentials.com website review

A phone's processor spends 7.7 s on main-thread work while loading, 3.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,686 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Google Tag Manager, Shopify and Clarity and others), adding 2.2 MB and 1.6 s of main-thread time.

About 877 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

Your mobile performance score is 61. Pages that score under 90 lose visitors before the first paint.

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

Google Tag Manager costs a phone 585 ms of main-thread work and 637 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.

monkcommerce.app costs a phone 202 ms of main-thread work and 598 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 219 ms of main-thread work and 400 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 142 ms of main-thread work and 320 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.

13 files are served with short cache lifetimes, so returning visitors download them again (221 KiB).

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 200 ms).

About 49 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

14 long tasks block the main thread while loading, the longest for 155 ms. During a long task the page ignores taps.

3 images could be 107 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 51 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.

3 KiB could be saved by minifying JavaScript.

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.

The page becomes fully interactive after 22.0 s. Good is under 3.8 s.

Visually, the page fills in at 7.4 s (Speed Index). Good is under 3.4 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.

Real visitors wait 245 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Scripts block taps and scrolling for 553 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 139 ms to 162 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.4 MB in 372 requests on a phone: scripts 2.3 MB (126), other files 1.2 MB (206) and images 602 KiB (23). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.24 g of CO₂e: 148.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Images must have alternative text: 25 elements on the page fail this check, rated critical by axe-core.

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

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

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.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

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

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

Elements with visible text labels do not have matching accessible names. (4 elements).

Your meta description is 296 characters; Google truncates after about 160, so the end of your pitch is cut.

1 link has no real href, so search engines can't follow it.

The homepage links to 205 pages on swimessentials.com and 16 external pages.

Your Organization JSON-LD is missing logo, sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://www.swimessentials.com/collections/outlet/Shop-products-in-our-last-chane-collection, whose canonical is https://www.swimessentials.com/collections/outlet. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 15 pages linked from your homepage (of 81 found) and read each the way a search engine does.

14 of 42 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“Authorization will not be covered by the wildcard symbol (*) in CORS `Access-Control-Allow-Headers`…”).

Social proof on the homepage: 3 testimonial or review blocks. 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.

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 805 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 and 1 more (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 8 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 38 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
