Speed

11 to fix41
  • Reduce unused JavaScript

    1.1 s · 931 KiB

    About 931 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.1 s faster on a phone.

  • Render-blocking requests

    1.4 s

    7 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

  • Mobile performance score: 41

    41/100

    Your mobile performance score is 41. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

  • Main-thread work: 7.8 s

    A phone's processor spends 7.8 s on main-thread work while loading, 3.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • 3,247 HTML elements

    The page has 3,247 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

  • 8 third-party services on the page

    8 third-party services load with your homepage (Google Tag Manager, Clarity and Klaviyo and others), adding 1.6 MB and 1.5 s of main-thread time.

  • Google Tag Manager adds 814 ms

    814 ms

    Google Tag Manager costs a phone 814 ms of main-thread work and 895 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.

  • Use efficient cache lifetimes

    350 ms · 489 KiB

    28 files are served with short cache lifetimes, so returning visitors download them again (489 KiB).

  • Improve image delivery

    756 KiB

    43 images could be 756 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • 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.

  • Clarity adds 278 ms

    278 ms

    Clarity costs a phone 278 ms of main-thread work and 29 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.

  • Font display

    50 ms

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

  • Legacy JavaScript

    46 KiB

    Polyfills for old browsers add 46 KiB JavaScript that modern phones do not need.

  • Reduce unused CSS

    34 KiB

    About 34 KiB of CSS is downloaded but never applied on this page.

  • 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.

  • Minify JavaScript

    2 KiB

    2 KiB could be saved by minifying JavaScript.

1 checks passed
  • Server response: 13 ms

    13 ms

    Your server sent the HTML in 13 ms, well inside Google's 600 ms guideline.

Core Web Vitals

5 to fix100
  • Largest Contentful Paint: 18.3 s

    18.3 s

    Your largest element takes 18.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

  • Time to Interactive: 28.4 s

    28.4 s

    The page becomes fully interactive after 28.4 s. Good is under 3.8 s.

  • Speed Index: 10.1 s

    10.1 s

    Visually, the page fills in at 10.1 s (Speed Index). Good is under 3.4 s.

  • Total Blocking Time: 1.3 s

    1.3 s

    Scripts block taps and scrolling for 1.3 s in total while the page loads. Good is under 200 ms.

  • 1 image without width and height

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

  • Tap response (INP) got 17% slower for real visitors

    +17%

    Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 92 ms to 107 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Largest content (LCP) held steady for real visitors

    -2%

    Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.5 s to 1.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

8 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: 2.1 s

    2.1 s

    Real visitors wait 2.1 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • Real-user INP: 96 ms

    96 ms

    Real visitors wait 96 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

  • Real-user CLS: 0.00

    0.00

    For real visitors the layout shifts by 0.00 (75th percentile). Good is under 0.1.

  • Real-user FCP: 1.3 s

    1.3 s

    Real visitors see the first content after 1.3 s (75th percentile). Good is under 1.8 s.

  • Real-user TTFB: 440 ms

    440 ms

    Real visitors wait 440 ms for your server to start answering (75th percentile). Good is under 800 ms.

  • First Contentful Paint: 1.3 s

    1.3 s

    The first text or image appears after 1.3 s, inside the 1.8 s “good” threshold.

  • Cumulative Layout Shift: 0.011

    0.011

    The layout barely moves while loading (CLS 0.011, good is under 0.1).

Images and page weight

3 to fix53
  • Page weight: 18.8 MB in 482 requests

    18.8 MB

    Your homepage downloads 18.8 MB in 482 requests on a phone: media 11.0 MB (2), images 4.4 MB (171) and scripts 2.2 MB (111). Under 2 MB keeps phones on slow connections fast.

  • 24 images below the first screen load straight away

    24 images further down the page (1.6 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

  • 4 images far larger than shown

    96 KiB

    4 images are downloaded at several times the size a phone draws them, for example Copy_of_AUSTIN_GAYNE_2_800x.png at 800 px wide, shown at 247 px. Resized copies would save about 96 KiB.

  • 2 images in older formats

    2 images (143 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.

  • About 5.3 g of CO₂ per visit

    5.32 g

    By the Sustainable Web Design model, a visit to your homepage emits about 5.32 g of CO₂e: 638.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Accessibility

7 to fixGoogle 8092
  • 2 text elements with low contrast

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

  • 38 images without alt text

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

  • All page content should be contained by landmarks (38 elements)

    All page content should be contained by landmarks: 38 elements on the page fail this check, rated moderate by axe-core.

  • Zoom is disabled

    The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

  • Alternative text of images should not be repeated as text (39 elements)

    Alternative text of images should not be repeated as text: 39 elements on the page fail this check, rated minor by axe-core.

  • 12 links without text

    12 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.

  • Headings skip levels

    Headings skip levels (h2 → h4, h1 → h4 and h1 → h3), which makes the page harder to scan with a screen reader.

1 checks passed
  • 46 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 53 WCAG 2.2 A/AA and best-practice rules on the phone render: 46 passed and 7 failed. 2 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

2 to fixGoogle 9291
  • No structured data

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

  • 7 H1 headlines

    There are 7 <h1> headlines (“BEST SELLERS”, “POP CULTURE INFUSED PERFORMANCE GEAR” and “BUILT FOR THE EXTRAORDINARY”). One clear main headline is easier for people and search engines.

  • Open Graph partly set

    Open Graph is missing og:title and og:description, so shared links fall back to guesses.

  • No X (Twitter) card tag

    No twitter:card tag. X falls back to Open Graph, which is incomplete here.

  • 288 internal links, 7 external

    The homepage links to 288 pages on superx.co and 7 external pages.

5 checks passed
  • Meta description: 159 characters

    Your meta description is 159 characters: “SuperX is world's leader in pop culture infused activewear, partnering with Marvel, Star Wars, DC Comics, Power Rangers…”.

  • Title: 38 characters

    Your title is a healthy 38 characters: “SUPERX: Best Superhero Workout Apparel”.

  • Canonical URL set

    The canonical URL is https://superxapparel.com/.

  • 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://superxapparel.com/sitemap.xml.

AI search readiness

1 to fix88
  • No Organization structured data

    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.

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.

  • Text is in the HTML

    Your server sends the page's text in the HTML (1,163 words), so crawlers that don't run JavaScript still read it.

  • llms.txt published

    The site publishes https://superxapparel.com/llms.txt (6 KiB, 8 links), a plain-text guide to the site for AI tools.

Other pages

3 to fix85
  • 11 pages without a meta description

    https://superxapparel.com/pages/avengers-doomsday-early-access, https://superxapparel.com/pages/star-wars%E2%84%A2-early-access, https://superxapparel.com/collections/dc-comics, https://superxapparel.com/collections/my-hero-academia, https://superxapparel.com/collections/star-wars and https://superxapparel.com/collections/invincible and 5 others have no meta description, so Google writes the search snippet from whatever text it finds.

  • 1 link to non-canonical URLs

    Your homepage links to 1 page by a URL that isn't its canonical one, for example https://superxapparel.com/pages/star-wars%E2%84%A2-early-access, whose canonical is https://superxapparel.com/pages/star-wars%e2%84%a2-early-access. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

  • 14 pages without an H1

    https://superxapparel.com/pages/avengers-doomsday-early-access, https://superxapparel.com/pages/star-wars%E2%84%A2-early-access, https://superxapparel.com/collections/marvel, https://superxapparel.com/collections/dc-comics, https://superxapparel.com/collections/my-hero-academia and https://superxapparel.com/collections/star-wars and 8 others have no <h1> headline, so visitors and search engines get no clear main topic.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 142 found) and read each the way a search engine does.

4 checks passed
  • Linked pages load

    All 15 pages we checked loaded without an error.

  • 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 15 pages that loaded have a <title>.

Best practices

3 to fixGoogle 6988
  • 1 third-party cookie

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

  • 5 JavaScript errors while loading

    5 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

  • 1 distorted image

    1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

  • Missing source maps

    Large scripts ship without source maps.

  • Browser-reported issues

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

2 checks passed
  • Tap targets are thumb-sized

    230 of 233 tappable elements near the top are at least 24 px.

  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

1 to fix94
  • Local business without LocalBusiness data

    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.

  • No opening hours

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

  • No map or directions link

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

  • 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 932 words of copy

    The homepage carries about 932 words of visible text.

  • Urgency cues

    The page uses urgency cues (a countdown or limited-time wording).

7 checks passed
  • Clear next step on the first screen

    On a phone, the first screen shows a clear next step: “SHOP BY COLLAB” and “SHOP BY CHARACTER”.

  • 23 calls to action

    The homepage has 23 calls to action, for example “Early access Star Wars™ Join the list”, “SHOP BY COLLAB” and “Shop all collabs”.

  • 3 short forms

    3 short forms (1 field at most) are right on the homepage.

  • Social proof on the page

    Social proof on the homepage: 5 testimonial or review blocks, 11 customer or partner logos, a star rating and “100,000+ CUSTOMERS”.

  • Analytics in place

    Analytics detected: Google Tag Manager, Google Analytics and Microsoft Clarity.

  • Direct contact links

    Visitors can reach you directly: 2 phone links and 0 email links.

  • Phone number on the homepage

    Your phone number is on the homepage as a tap-to-call link.

Privacy and tracking

1 to fix
  • 9 trackers load before any consent

    9

    Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 4 mores (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.

  • 35 cookies set on arrival

    35

    Opening the homepage sets 35 cookies, 2 of them by other companies (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.

  • 64 other companies contacted

    Loading the homepage contacts 64 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 superx.co, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
