polarwise.com website review

10 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

A phone's processor spends 5.7 s on main-thread work while loading, 2.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (GitHub, Clarity and Klaviyo and others), adding 26.2 MB and 781 ms of main-thread time.

Shopify costs a phone 134 ms of main-thread work and 25.2 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.

Your mobile performance score is 64. Pages that score under 90 lose visitors before the first paint.

About 114 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 580 ms faster on a phone.

21 files are served with short cache lifetimes, so returning visitors download them again (454 KiB).

About 297 KiB of JavaScript is downloaded but never used on this page.

GitHub costs a phone 183 ms of main-thread work and 373 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 2,151 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Klaviyo costs a phone 147 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.

10 long tasks block the main thread while loading, the longest for 148 ms. During a long task the page ignores taps.

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

3 images could be 45 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 29 KiB JavaScript that modern phones do not need.

8 KiB JavaScript is shipped twice across bundles.

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.

5 KiB could be saved by minifying JavaScript.

The page becomes fully interactive after 17.9 s. Good is under 3.8 s.

Your largest element takes 5.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Visually, the page fills in at 6.7 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 147 ms to 179 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 302 ms in total while the page loads. Good is under 200 ms.

Your homepage downloads 41.3 MB in 477 requests on a phone: media 37.3 MB (6), other files 1.9 MB (294) and scripts 1.3 MB (110). Under 2 MB keeps phones on slow connections fast.

1 image (40 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 11.71 g of CO₂e: 1405.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 buttons have no accessible name, so screen readers announce just “button”.

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

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

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.

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

Headings skip levels (h2 → h6 and h1 → h3), which makes the page harder to scan with a screen reader.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

There are 2 <h1> headlines (“Polarwise” and “Sweat-free living starts her e”). One clear main headline is easier for people and search engines.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 157 pages on polarwise.com and 6 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no https://polarwise.com/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

https://polarwise.com/collections/bestseller has 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.

We fetched 15 pages linked from your homepage (of 39 found) and read each the way a search engine does.

2 images failed to load on a phone, for example https://github.com/TheaiBoosters/vg-hosting-template-v2/blob/master/Ontwerp%20zonder%20titel-32.png?raw=true.

15 of 57 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

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

Chrome logged issues while loading the page (“Cookie”).

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 1,122 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 2 mores (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 31 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 53 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
