marvel.com website review

134 files are served with short cache lifetimes, so returning visitors download them again (4.5 MB).

About 2.3 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 6.5 s faster on a phone.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.1 s.

Your mobile performance score is 28 (desktop: 55). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 9.2 s on main-thread work while loading, 5.4 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google CDN, disney.com and Google/Doubleclick Ads and others), adding 5.3 MB and 3.2 s of main-thread time.

29 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 800 ms faster on a phone.

Google CDN costs a phone 868 ms of main-thread work and 1.4 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.

disney.com costs a phone 696 ms of main-thread work and 1.9 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.

Google/Doubleclick Ads costs a phone 586 ms of main-thread work and 876 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.

About 132 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.

Google Tag Manager costs a phone 361 ms of main-thread work and 302 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.

20 long tasks block the main thread while loading, the longest for 337 ms. During a long task the page ignores taps.

espn.com costs a phone 261 ms of main-thread work and 269 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.

Polyfills for old browsers add 40 KiB JavaScript that modern phones do not need.

Desktop scores 55 but mobile only 28. A gap that wide usually means heavy scripts and images that hit phones hardest.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

3 KiB could be saved by minifying JavaScript.

2 KiB could be saved by minifying CSS.

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.

The first text or image appears after 15.2 s on a phone. Good is under 1.8 s.

Your largest element takes 27.5 s to render on a phone. Google's threshold for “good” is 2.5 s.

The page becomes fully interactive after 46.4 s. Good is under 3.8 s.

Visually, the page fills in at 15.2 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 2.0 s in total while the page loads. Good is under 200 ms.

Real visitors see the first content after 2.0 s (75th percentile). Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' tap response (inp) went from 147 ms to 144 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 2.2 s to 2.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 10.8 MB in 501 requests on a phone: scripts 5.4 MB (213), images 3.5 MB (118) and other files 1.1 MB (148). Under 2 MB keeps phones on slow connections fast.

36 images further down the page (1.5 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

9 images are downloaded at several times the size a phone draws them, for example 20250331_newtomu_base_set_dsk.webp at 2,000 px wide, shown at 390 px. Resized copies would save about 429 KiB.

3 images (394 KiB) are 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 3.07 g of CO₂e: 367.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Some list items are not inside a list.

ARIA commands must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 28 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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

1 form field has no label, so screen readers announce an empty box and autofill guesses.

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

Your title is 72 characters, so Google will cut it off around 60: “Marvel.com | The Official Site for Marvel Movies, Characters, Comics, TV”.

Structured data found (Organization and WebSite) but with 1 problem, for example “WebSite: missing name”.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

The homepage links to 93 pages on marvel.com and 35 external pages.

There is no https://www.marvel.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.

robots.txt blocks GPTBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers, which the crawlers above handle.

https://www.marvel.com/rss/feed has no <title>, so Google invents the link text in results.

https://www.marvel.com/rss/feed has no meta description, so Google writes the search snippet from whatever text it finds.

https://www.marvel.com/unlimited and https://www.marvel.com/culture-lifestyle/books use the same meta description. A description written for each page earns more clicks.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://www.marvel.com/podcasts, whose canonical is https://www.marvel.com/digital-series/podcasts. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://www.marvel.com/rpg, https://www.marvel.com/shop/marvel-must-haves and https://www.marvel.com/rss/feed have no <h1> headline, so visitors and search engines get no clear main topic.

https://www.marvel.com/unlimited 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 52 found) and read each the way a search engine does.

7 of 34 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.

3 errors were logged to the browser console while the page loaded, for example “Framing 'https://www.google.com/' violates the following report-only Content Security Policy directive: "frame-ancestor…”.

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

Large scripts ship without source maps.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

Social proof on the homepage: a star rating. Pairing it with named testimonials or customer logos makes it far more convincing.

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.

The homepage shows no opening hours. If customers visit or call, show when.

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

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 1,021 words of visible text.

Before a visitor clicks anything, the page loads Comscore, Google Ads, Google Tag Manager and Meta Pixel (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 26 cookies (measured from a US location before any click).

Loading the homepage contacts 37 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
