backofbottle.com website review

About 2.0 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 14.9 s faster on a phone.

30 files are served with short cache lifetimes, so returning visitors download them again (403 KiB).

A phone's processor spends 4.5 s on main-thread work while loading, 2.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 57. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Vimeo, Klaviyo and tidio.co and others), adding 4.2 MB and 459 ms of main-thread time.

4 images could be 863 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 66 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 750 ms faster on a phone.

Vimeo costs a phone 131 ms of main-thread work and 2.5 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.

Polyfills for old browsers add 31 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.

Klaviyo costs a phone 98 ms of main-thread work and 311 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.

tidio.co costs a phone 60 ms of main-thread work and 515 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 49 ms of main-thread work and 516 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.

53 KiB could be saved by minifying JavaScript.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 150 ms.

6 long tasks block the main thread while loading, the longest for 138 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.

4 KiB could be saved by minifying CSS.

Your largest element takes 27.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

Visually, the page fills in at 17.8 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 35.7 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 105 ms to 137 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.5 s to 1.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 16.4 MB in 329 requests on a phone: media 9.6 MB (4), scripts 3.8 MB (113) and images 1.4 MB (28). Under 2 MB keeps phones on slow connections fast.

1 image (206 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.

2 images further down the page (238 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 4.64 g of CO₂e: 556.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

5 frames have no title, so screen-reader users cannot tell what they contain.

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

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

1 image has no alt text, which hurts accessibility and image search.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 2 elements on the page fail this check, rated moderate by axe-core.

4 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. (1 element).

Your meta description is only 39 characters: “Built with Stylists. Made for Everyone.”. 70 to 160 characters is enough to sell the click.

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

The homepage links to 77 pages on backofbottle.com and 6 external pages.

/collections/all, /collections/hydration, /collections/volume, /collections/smooth-finish, /collections/oily-hair and /collections/repair-and-strengthen and 2 others have no meta description, so Google writes the search snippet from whatever text it finds.

/pages/bestsellers and /pages/philosophy have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 32 found) and read each the way a search engine does.

4 of 20 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

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 analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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 339 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel (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 18 cookies, 2 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 40 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
