Speed

11 to fix37
  • Reduce unused JavaScript

    2.5 s · 812 KiB

    About 812 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.5 s faster on a phone.

  • Render-blocking requests

    2.3 s

    3 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.3 s.

  • Mobile performance score: 37

    37/100

    Your mobile performance score is 37 (desktop: 55). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

  • Main-thread work: 7.4 s

    A phone's processor spends 7.4 s on main-thread work while loading, 3.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • Reduce unused CSS

    600 ms · 126 KiB

    About 126 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.

  • 8 third-party services on the page

    8 third-party services load with your homepage (Google/Doubleclick Ads, lumiere.gg and Google Tag Manager and others), adding 1.1 MB and 601 ms of main-thread time.

  • Improve image delivery

    300 ms · 275 KiB

    14 images could be 275 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.

  • Use efficient cache lifetimes

    150 ms · 337 KiB

    45 files are served with short cache lifetimes, so returning visitors download them again (337 KiB).

  • 20 long tasks on the main thread

    20 long tasks block the main thread while loading, the longest for 333 ms. During a long task the page ignores taps.

  • 2,077 HTML elements

    The page has 2,077 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

  • Google/Doubleclick Ads adds 136 ms

    136 ms

    Google/Doubleclick Ads costs a phone 136 ms of main-thread work and 309 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.

  • Legacy JavaScript

    150 ms · 24 KiB

    Polyfills for old browsers add 24 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

  • Minify JavaScript

    7 KiB

    7 KiB could be saved by minifying JavaScript.

  • Chained critical requests

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

  • Forced reflow

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

  • Server response: 4 ms

    4 ms

    Your server sent the HTML in 4 ms, well inside Google's 600 ms guideline.

Core Web Vitals

5 to fix100
  • Largest Contentful Paint: 11.0 s

    11.0 s

    Your largest element takes 11.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “LaDainian Tomlinson Legends 89 OVR - Madden NFL 27”.

  • First Contentful Paint: 6.8 s

    6.8 s

    The first text or image appears after 6.8 s on a phone. Good is under 1.8 s.

  • Time to Interactive: 20.5 s

    20.5 s

    The page becomes fully interactive after 20.5 s. Good is under 3.8 s.

  • Total Blocking Time: 980 ms

    980 ms

    Scripts block taps and scrolling for 980 ms in total while the page loads. Good is under 200 ms.

  • Speed Index: 6.8 s

    6.8 s

    Visually, the page fills in at 6.8 s (Speed Index). Good is under 3.4 s.

  • Tap response (INP) held steady for real visitors

    -5%

    Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' tap response (inp) went from 100 ms to 95 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Largest content (LCP) held steady for real visitors

    -7%

    Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 0.6 s to 0.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

7 checks passed
  • Passes Core Web Vitals for real visitors

    Real Chrome users on phones pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)).

  • Real-user LCP: 0.7 s

    0.7 s

    Real visitors wait 0.7 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • Real-user INP: 105 ms

    105 ms

    Real visitors wait 105 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

  • Real-user CLS: 0.01

    0.01

    For real visitors the layout shifts by 0.01 (75th percentile). Good is under 0.1.

  • Real-user FCP: 0.7 s

    0.7 s

    Real visitors see the first content after 0.7 s (75th percentile). Good is under 1.8 s.

  • Real-user TTFB: 261 ms

    261 ms

  • Cumulative Layout Shift: 0

    0

    The layout barely moves while loading (CLS 0, good is under 0.1).

Images and page weight

1 to fix85
  • Page weight: 3.6 MB in 525 requests

    3.6 MB

    Your homepage downloads 3.6 MB in 525 requests on a phone: scripts 1.6 MB (61), images 1.2 MB (147) and other files 367 KiB (272). Under 2 MB keeps phones on slow connections fast.

  • 10 images below the first screen load straight away

    10 images further down the page (290 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

  • About 1.0 g of CO₂ per visit

    1.01 g

    By the Sustainable Web Design model, a visit to your homepage emits about 1.01 g of CO₂e: 121.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 checks passed
  • Images use modern formats

    Every sizeable image is WebP, AVIF or SVG.

  • Images are sized for phones

    No image is downloaded at more than three times the size it is drawn on a phone.

Accessibility

13 to fixGoogle 8085
  • 1 button without a name

    1 button has no accessible name, so screen readers announce just “button”.

  • <svg> elements with an img or image role must have alternative text (25 elements)

    <svg> elements with an img or image role must have alternative text: 25 elements on the page fail this check, rated serious by axe-core.

  • 7 tap targets too small

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

  • Elements must only use permitted ARIA attributes (1 element)

    Elements must only use permitted ARIA attributes: 1 element on the page fails this check, rated serious by axe-core.

  • 10 images without alt text

    10 images have no alt text, which hurts accessibility and image search.

  • Main landmark should not be contained in another landmark (1 element)

    Main landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

  • Document should not have more than one main landmark (1 element)

    Document should not have more than one main landmark: 1 element on the page fails this check, rated moderate by axe-core.

  • Landmarks should have a unique role or role/label/title (i.e. accessible name) combination (1 element)

    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)

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

  • All page content should be contained by landmarks (1 element)

    All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

  • 4 links without text

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

  • 1 form field without a label

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

  • Table header text should not be empty (6 elements)

    Table header text should not be empty: 6 elements on the page fail this check, rated minor by axe-core.

  • <td> elements in a large <table> do not have table headers.

    <td> elements in a large <table> do not have table headers. (1 element).

1 checks passed
  • 49 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 61 WCAG 2.2 A/AA and best-practice rules on the phone render: 49 passed and 12 failed. 2 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

3 to fixGoogle 9279
  • No H1 headline

    There is no <h1>, so neither visitors nor Google get a clear main headline.

  • Title is long (79 characters)

    Your title is 79 characters, so Google will cut it off around 60: “Madden NFL 27 Ultimate Team Database - Player Ratings, Stats and Teams - MUT.GG”.

  • No canonical URL

    No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

  • 139 internal links, 14 external

    The homepage links to 139 pages on mut.gg and 14 external pages.

5 checks passed
  • Meta description: 70 characters

    Your meta description is 70 characters: “Madden NFL 27 Ultimate Team Database - Player Ratings, Stats and Teams”.

  • Structured data in place

    Structured data found: NewsMediaOrganization and WebSite.

  • Open Graph tags complete

    Open Graph tags are complete, so shared links show a title, description and image.

  • robots.txt in place

    robots.txt is in place and points crawlers to your sitemap.

  • XML sitemap found

    Your XML sitemap is reachable at https://www.mut.gg/sitemap.xml.

AI search readiness

100
  • No llms.txt

    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.

3 checks passed
  • AI answer engines may read the site

    Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.

  • Organization data: 4 of 6 facts

    Your Organization JSON-LD gives name, url, logo and sameAs (social profiles); description and contact details would complete it.

  • Text is in the HTML

    Your server sends the page's text in the HTML (576 words), so crawlers that don't run JavaScript still read it.

Other pages

1 to fix95
  • 1 page without an H1

    /lineup-builder has no <h1> headline, so visitors and search engines get no clear main topic.

  • 3 pages with very little text

    /lineup-builder, /compare and /upgrades have 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.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 83 found) and read each the way a search engine does.

6 checks passed
  • Linked pages load

    All 15 pages we checked loaded without an error.

  • Canonical URLs point to themselves

    No page we checked hands its ranking to a different URL.

  • Every page has a meta description

    All 14 pages that loaded have a meta description.

  • Titles are unique

    Every page we checked has its own title.

  • No linked page is hidden from search

    None of the pages we checked carries a noindex tag.

  • Every page has a title

    All 14 pages that loaded have a <title>.

Best practices

4 to fixGoogle 5483
  • 31 third-party cookies

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

  • 14 small tap targets

    14 of 40 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

  • Deprecated browser APIs

    The page uses 1 deprecated browser API that will stop working in future browsers (“The Topics API is deprecated and will be removed in a future release.”).

  • 6 JavaScript errors while loading

    6 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 403 ()”.

  • Browser-reported issues

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

  • Missing source maps

    Large scripts ship without source maps.

1 checks passed
  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

3 to fix67
  • No call to action on the first screen

    On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

  • Thin social proof

    Social proof on the homepage: 141 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

  • No direct contact details

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

  • No risk reducer

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

  • About 294 words of copy

    The homepage carries about 294 words of visible text.

3 checks passed
  • 1 call to action

    The homepage has 1 call to action, for example “Subscribe”.

  • 1 short form

    A short form (1 field at most) is right on the homepage.

  • Analytics in place

    Analytics detected: Google Analytics.

Privacy and tracking

1 to fix
  • 4 trackers load before any consent

    4

    Before a visitor clicks anything, the page loads Criteo, 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.

  • 3 cookies set on arrival

    3

    Opening the homepage sets 3 cookies (measured from a US location before any click).

  • No consent tool detected

    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.

  • 26 other companies contacted

    Loading the homepage contacts 26 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

Security, domain, email and software versions

The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at mut.gg, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
