knockknockstuff.com website review

Your mobile performance score is 65. Pages that score under 90 lose visitors before the first paint.

About 107 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 600 ms faster on a phone.

About 156 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.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

A phone's processor spends 2.8 s on main-thread work while loading, 717 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 2,658 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

12 images could be 185 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 200 ms faster on a phone.

6 files are served with short cache lifetimes, so returning visitors download them again (36 KiB).

6 third-party services load with your homepage (Klaviyo, Shopify and nfcube.com and others), adding 339 KiB and 164 ms of main-thread time.

3 long tasks block the main thread while loading, the longest for 109 ms. During a long task the page ignores taps.

Polyfills for old browsers add 19 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.

Your largest element takes 9.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “2026 Best Selling Gifts!”.

The page becomes fully interactive after 9.8 s. Good is under 3.8 s.

Visually, the page fills in at 5.8 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.9 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 101 ms to 105 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.8 MB in 193 requests on a phone: images 1.5 MB (70), other files 603 KiB (54) and scripts 545 KiB (57). Under 2 MB keeps phones on slow connections fast.

DTC_Mobile_Banner_R1_28b08619-c7e0-4a61-be93-7bbd6eff40b6.jp 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).

By the Sustainable Web Design model, a visit to your homepage emits about 0.80 g of CO₂e: 95.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 tap target is too small or too close together to hit reliably with a finger.

All page content should be contained by landmarks: 6 elements on the page fail this check, rated moderate by axe-core.

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.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

Headings skip levels (h1 → h6), 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.

The homepage links to 288 pages on knockknockstuff.com and 11 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://knockknockstuff.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.

Your homepage links to https://knockknockstuff.com/collections/knock-knock-pads, which answers with an error. Visitors hit a dead end and search engines drop it.

https://knockknockstuff.com/collections/knock-knock-kids and https://knockknockstuff.com/pages/kids all use the title “Knock Knock Kids”. Search engines can't tell which page to show for a search, so each competes with the others.

https://knockknockstuff.com/collections/bestsellers, https://knockknockstuff.com/collections/knock-knock-notepads, https://knockknockstuff.com/collections/knock-knock-kids, https://knockknockstuff.com/collections/books-book-related, https://knockknockstuff.com/collections/journals-planners and https://knockknockstuff.com/pages/kids have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://knockknockstuff.com/pages/kids, whose canonical is https://knockknockstuff.com/collections/knock-knock-kids. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://knockknockstuff.com/collections/knock-knock-kids and https://knockknockstuff.com/pages/kids have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 71 found) and read each the way a search engine does.

1 image is served at too low a resolution for sharp phone screens.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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 350 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 12 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 23 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
