cartoonnetwork.com website review

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

About 464 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 750 ms faster on a phone.

Your mobile performance score is 66 (desktop: 85). Pages that score under 90 lose visitors before the first paint.

4 files are served with short cache lifetimes, so returning visitors download them again (47 KiB).

Polyfills for old browsers add 51 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.

Google Tag Manager costs a phone 191 ms of main-thread work and 390 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.

8 third-party services load with your homepage (Google Tag Manager, Sentry and Amplitude Mobile Analytics and others), adding 703 KiB and 445 ms of main-thread time.

1 image could be 31 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

8 long tasks block the main thread while loading, the longest for 157 ms. During a long task the page ignores taps.

About 20 KiB of CSS is downloaded but never applied on this page.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 6.2 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 11.9 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.5 s to 2.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors wait 1.3 s for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 5.6 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 282 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 188 ms to 195 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

970x250 no show names.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 (32 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 0.46 g of CO₂e: 54.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA dialog and alertdialog nodes should have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

<svg> elements with an img or image role must have alternative text: 1 element on the page fails this check, rated serious by axe-core.

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

Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

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

No XML sitemap at https://www.hbomax.com/sitemap.xml, so Google discovers your pages only by following links.

The homepage links to 50 pages on cartoonnetwork.com and 12 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 /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.

/channel 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 31 found) and read each the way a search engine does.

12 of 44 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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

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

2 errors were logged to the browser console while the page loaded, for example “Cannot get language path: missing required parameters. Missing: languageBcp47Code”.

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

Large scripts ship without source maps.

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

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage has only about 189 words of visible text; thin pages give Google and first-time buyers little to go on.

There is no form on the homepage, so every lead has to click through to another page first.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics and Google Tag Manager (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 14 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 11 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
