ion8.com website review

About 241 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.

Your mobile performance score is 59. Pages that score under 90 lose visitors before the first paint.

16 images could be 914 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

8 third-party services load with your homepage (Shopify, Trust Pilot and Clarity and others), adding 1.0 MB and 640 ms of main-thread time.

14 files block the first paint until they finish downloading. Deferring or inlining them could save about 700 ms.

About 88 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

A phone's processor spends 3.8 s on main-thread work while loading, 1.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Shopify costs a phone 276 ms of main-thread work and 591 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 2,821 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

12 files are served with short cache lifetimes, so returning visitors download them again (59 KiB).

Polyfills for old browsers add 55 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 250 ms faster on a phone.

6 long tasks block the main thread while loading, the longest for 114 ms. During a long task the page ignores taps.

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.

Your largest element takes 14.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 15.0 s. Good is under 3.8 s.

Visually, the page fills in at 7.3 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.0 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 232 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 128 ms to 133 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 7.9 MB in 259 requests on a phone: media 4.4 MB (2), images 1.3 MB (30) and scripts 960 KiB (86). Under 2 MB keeps phones on slow connections fast.

4 images are downloaded at several times the size a phone draws them, for example All_bottles_collection_card_2_1.jpg at 1,993 px wide, shown at 296 px. Resized copies would save about 550 KiB.

1 image (274 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 2.24 g of CO₂e: 268.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Some lists contain elements other than list items, which screen readers announce wrongly.

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

Page should contain a level-one heading: 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.

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

Your title is 81 characters, so Google will cut it off around 60: “ION8 Leak-Proof Stainless Steel Water Bottles | BPA-Free Kids & Adults – ION8 USA”.

The homepage links to 93 pages on ion8.com and 5 external pages.

https://ion8.com/collections/tour-12oz-bottles has no meta description, so Google writes the search snippet from whatever text it finds.

https://ion8.com/pages/shipping-rates-usa, https://ion8.com/collections/water-bottles, https://ion8.com/collections/official-nba-water-bottles, https://ion8.com/collections/official-nflpa-bottles, https://ion8.com/collections/kids-water-bottles and https://ion8.com/collections/water-bottle-accessories 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 42 found) and read each the way a search engine does.

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

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

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 577 words of visible text.

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 16 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 25 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
