knackbags.com website review

24 files are served with short cache lifetimes, so returning visitors download them again (937 KiB).

About 1.1 MB 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.

10 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

A phone's processor spends 6.8 s on main-thread work while loading, 3.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Klaviyo and Google CDN and others), adding 2.9 MB and 1.5 s of main-thread time.

10 images could be 1.0 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 600 ms faster on a phone.

Your mobile performance score is 56. Pages that score under 90 lose visitors before the first paint.

Google Tag Manager costs a phone 432 ms of main-thread work and 676 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.

Google CDN costs a phone 250 ms of main-thread work and 877 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 258 ms of main-thread work and 648 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 2,116 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Shopify costs a phone 59 ms of main-thread work and 418 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 long tasks block the main thread while loading, the longest for 154 ms. During a long task the page ignores taps.

Polyfills for old browsers add 57 KiB JavaScript that modern phones do not need.

51 KiB JavaScript is shipped twice across bundles.

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

About 36 KiB of CSS is downloaded but never applied on this page.

9 KiB could be saved by minifying CSS.

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

The page becomes fully interactive after 38.4 s. Good is under 3.8 s.

Visually, the page fills in at 10.5 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 411 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 132 ms to 150 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.3 s to 1.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 11.7 MB in 551 requests on a phone: fonts 5.1 MB (10), scripts 2.9 MB (135) and images 1.8 MB (40). Under 2 MB keeps phones on slow connections fast.

Knack.WhatMatters.png is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

1 image is downloaded at several times the size a phone draws it, for example knack.webp at 1,376 px wide, shown at 390 px. Resized copies would save about 29 KiB.

2 images further down the page (53 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 3.32 g of CO₂e: 398.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

[role="img"] and [role="image"] elements must have alternative text: 6 elements on the page fail this check, rated serious by axe-core.

Scrollable region must have keyboard access: 3 elements on the page fail this check, rated serious by axe-core.

1 frame has no title, so screen-reader users cannot tell what it contains.

Summary elements must have discernible text: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 5 elements on the page fail this check, rated moderate by axe-core.

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

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

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

Your <h1> is empty.

The homepage links to 164 pages on knackbags.com and 15 external pages.

https://knackbags.com/collections/expandable-backpacks, https://knackbags.com/collections/expandable-travel-duffel, https://knackbags.com/collections/expandable-tote-bags, https://knackbags.com/collections/travel-accessories, https://knackbags.com/collections/compressible-shoe-bags and https://knackbags.com/collections/travel-packing-cubes and 2 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 69 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://d3k81ch9hvuctc.cloudfront.net/company/LrMHwS/images/90227ef9-3bf6-4870-936c-5a5290a99535.png.

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

5 errors were logged to the browser console while the page loaded, for example “Cannot assign to read only property 'protect' of object '#<Object>'”.

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

Social proof on the homepage: 72 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.

The homepage carries about 610 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 22 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 50 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
