Speed

12 to fix58
  • Main-thread work: 8.0 s

    A phone's processor spends 8.0 s on main-thread work while loading, 4.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • 3,924 HTML elements

    The page has 3,924 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, preproduct.io and ContentSquare and others), adding 2.3 MB and 2.4 s of main-thread time.

  • Reduce unused JavaScript

    50 ms · 1.7 MB

    About 1.7 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 50 ms faster on a phone.

  • Use efficient cache lifetimes

    1.5 MB

    51 files are served with short cache lifetimes, so returning visitors download them again (1.5 MB).

  • Mobile performance score: 58

    58/100

    Your mobile performance score is 58. Pages that score under 90 lose visitors before the first paint.

  • Google Tag Manager adds 707 ms

    707 ms

    Google Tag Manager costs a phone 707 ms of main-thread work and 691 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.

  • preproduct.io adds 449 ms

    449 ms

    preproduct.io costs a phone 449 ms of main-thread work and 43 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.

  • ContentSquare adds 416 ms

    416 ms

    ContentSquare costs a phone 416 ms of main-thread work and 212 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.

  • Improve image delivery

    333 KiB

    13 images could be 333 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • Klaviyo adds 161 ms

    161 ms

    Klaviyo costs a phone 161 ms of main-thread work and 350 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.

  • Shopify adds 107 ms

    107 ms

    Shopify costs a phone 107 ms of main-thread work and 520 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.

  • Render-blocking requests

    200 ms

    5 files block the first paint until they finish downloading. Deferring or inlining them could save about 200 ms.

  • 20 long tasks on the main thread

    20 long tasks block the main thread while loading, the longest for 185 ms. During a long task the page ignores taps.

  • Reduce unused CSS

    90 ms · 43 KiB

    About 43 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 90 ms faster on a phone.

  • Legacy JavaScript

    53 KiB

    Polyfills for old browsers add 53 KiB JavaScript that modern phones do not need.

  • Font display

    50 ms

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

  • Minify JavaScript

    30 KiB

    30 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.

  • Duplicated JavaScript

    2 KiB

    2 KiB JavaScript is shipped twice across bundles.

  • Minify CSS

    2 KiB

    2 KiB could be saved by minifying CSS.

  • Server response: 17 ms

    17 ms

    Your server sent the HTML in 17 ms, well inside Google's 600 ms guideline.

Core Web Vitals

6 to fix100
  • Time to Interactive: 37.9 s

    37.9 s

    The page becomes fully interactive after 37.9 s. Good is under 3.8 s.

  • Speed Index: 7.7 s

  • Total Blocking Time: 1.0 s

    1.0 s

    Scripts block taps and scrolling for 1.0 s in total while the page loads. Good is under 200 ms.

  • Largest Contentful Paint: 3.5 s

    3.5 s

    Your largest element takes 3.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

  • First Contentful Paint: 2.5 s

    2.5 s

    The first text or image appears after 2.5 s on a phone. Good is under 1.8 s.

  • 15 images without width and height

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

  • Tap response (INP) got 19% slower for real visitors

    +19%

    Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 126 ms to 153 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Largest content (LCP) held steady for real visitors

    +4%

    Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 2.2 s to 2.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

7 checks passed

    0

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

Images and page weight

1 to fix70
  • Page weight: 8.3 MB in 505 requests

    8.3 MB

    Your homepage downloads 8.3 MB in 505 requests on a phone: scripts 3.9 MB (136), images 2.3 MB (49) and other files 1.8 MB (293). Under 2 MB keeps phones on slow connections fast.

  • About 2.3 g of CO₂ per visit

    2.35 g

    By the Sustainable Web Design model, a visit to your homepage emits about 2.35 g of CO₂e: 281.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 checks passed
  • Images use modern formats

    Every sizeable image is WebP, AVIF or SVG.

  • Images load when needed

    Images below the first screen wait until the visitor scrolls to them.

  • Images are sized for phones

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

Accessibility

5 to fixGoogle 9095
  • 6 text elements with low contrast

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

  • All page content should be contained by landmarks (9 elements)

    All page content should be contained by landmarks: 9 elements on the page fail this check, rated moderate by axe-core.

  • Alternative text of images should not be repeated as text (36 elements)

    Alternative text of images should not be repeated as text: 36 elements on the page fail this check, rated minor by axe-core.

  • 1 link without text

    1 visible link has no text or label, so screen readers cannot say where it goes.

  • 1 tap target too small

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

  • Headings skip levels

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

2 checks passed
  • Every image has alt text

    All 374 images in the HTML carry an alt attribute.

  • 50 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 54 WCAG 2.2 A/AA and best-practice rules on the phone render: 50 passed and 4 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

4 to fixGoogle 10083
  • No structured data

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

  • 47 H1 headlines

    There are 47 <h1> headlines (“new coats”, “The Boyfriend” and “Rosette Jumper”). One clear main headline is easier for people and search engines.

  • Meta description is long (234 characters)

    Your meta description is 234 characters; Google truncates after about 160, so the end of your pitch is cut.

  • No social preview image

    No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

  • No X (Twitter) card tag

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

  • 220 internal links, 4 external

    The homepage links to 220 pages on withnothingunderneath.com and 4 external pages.

4 checks passed
  • Title: 44 characters

    Your title is a healthy 44 characters: “With Nothing Underneath | Shirts to live in.”.

  • Canonical URL set

    The canonical URL is https://www.withnothingunderneath.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://www.withnothingunderneath.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 (1,029 words), so crawlers that don't run JavaScript still read it.

  • llms.txt published

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

Other pages

2 to fix90
  • 1 page without a meta description

    /collections/denim-chambray has 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 /collections/shirts-all-fabrics, whose canonical is /collections/womens-shirts. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 100 found) and read each the way a search engine does.

5 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.

  • Every page has an H1

    Each page we checked has a main headline.

  • 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 9671
  • 1 broken image

    1 image failed to load on a phone, for example https://d3k81ch9hvuctc.cloudfront.net/company/Tnw3Ui/images/2e362cd9-973c-42ed-9cfb-a9a8ae1ab5ff.jpeg.

  • 65 small tap targets

    65 of 164 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

  • 6 JavaScript errors while loading

    6 errors were logged to the browser console while the page loaded, for example “analytics is not defined”.

1 checks passed
  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

2 to fix75
  • No social proof

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

  • 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 604 words of copy

    The homepage carries about 604 words of visible text.

4 checks passed
  • Clear next step on the first screen

    On a phone, the first screen shows a clear next step: “Shop” and “Menu Shop”.

  • 13 calls to action

    The homepage has 13 calls to action, for example “SHOP ALL”, “Shop” and “Menu Shop”.

  • 3 short forms

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

  • Analytics in place

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

Privacy and tracking

  • 7 trackers load before any consent

    7

    Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Hotjar and Klaviyo and 2 mores (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

  • 37 cookies set on arrival

    37

    Opening the homepage sets 37 cookies (measured from a US location before any click).

  • 53 other companies contacted

    Loading the homepage contacts 53 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

1 checks passed
  • Consent tool: Cookiebot

    A consent management tool (Cookiebot) loads with the page.
