Speed

8 to fix60
  • Main-thread work: 6.5 s

    A phone's processor spends 6.5 s on main-thread work while loading, 3.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • 8 third-party services on the page

    8 third-party services load with your homepage (Google Tag Manager, Shopify and TikTok and others), adding 2.1 MB and 2.2 s of main-thread time.

  • Mobile performance score: 60

    60/100

    Your mobile performance score is 60. Pages that score under 90 lose visitors before the first paint.

  • Google Tag Manager adds 852 ms

    852 ms

    Google Tag Manager costs a phone 852 ms of main-thread work and 697 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.

  • Reduce unused JavaScript

    758 KiB

    About 758 KiB of JavaScript is downloaded but never used on this page.

  • Render-blocking requests

    700 ms

    3 files block the first paint until they finish downloading. Deferring or inlining them could save about 700 ms.

  • Shopify adds 568 ms

    568 ms

    Shopify costs a phone 568 ms of main-thread work and 793 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 on the main thread

    20 long tasks block the main thread while loading, the longest for 362 ms. During a long task the page ignores taps.

  • Improve image delivery

    92 KiB

    4 images could be 92 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • Reduce unused CSS

    57 KiB

    About 57 KiB of CSS is downloaded but never applied on this page.

  • Use efficient cache lifetimes

    44 KiB

    7 files are served with short cache lifetimes, so returning visitors download them again (44 KiB).

  • Legacy JavaScript

    37 KiB

    Polyfills for old browsers add 37 KiB JavaScript that modern phones do not need.

  • 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: 7 ms

    7 ms

    Your server sent the HTML in 7 ms, well inside Google's 600 ms guideline.

    1.1 s

    The first text or image appears after 1.1 s, inside the 1.8 s “good” threshold.

  • 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: 3.7 MB in 253 requests

    3.7 MB

    Your homepage downloads 3.7 MB in 253 requests on a phone: scripts 2.2 MB (104), other files 820 KiB (103) and images 537 KiB (23). Under 2 MB keeps phones on slow connections fast.

  • 1 image below the first screen load straight away

    1 image further down the page (45 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

  • About 1.1 g of CO₂ per visit

    1.06 g

    By the Sustainable Web Design model, a visit to your homepage emits about 1.06 g of CO₂e: 126.9 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

7 to fixGoogle 8591
  • 4 tap targets too small

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

  • Orphan list items

    Some list items are not inside a list.

  • 1 image without alt text

    1 image has no alt text, which hurts accessibility and image search.

  • 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.

  • 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.

  • 3 links without text

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

  • ARIA role should be appropriate for the element (1 element)

    ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

1 checks passed
  • 49 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 56 WCAG 2.2 A/AA and best-practice rules on the phone render: 49 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.

Other pages

2 to fix90
  • 1 page without a meta description

    https://lynvn.com/collections/lyn-infinite-men has no meta description, so Google writes the search snippet from whatever text it finds.

  • 14 pages without an H1

    https://lynvn.com/collections/subscription, https://lynvn.com/collections/view-new, https://lynvn.com/collections/bestseller, https://lynvn.com/collections/lyn-superstar, https://lynvn.com/collections/lyn-infinite and https://lynvn.com/collections/lyn-infinite-men and 8 others have no <h1> headline, so visitors and search engines get no clear main topic.

  • 13 pages slow to respond

    https://lynvn.com/collections/view-new, https://lynvn.com/collections/bestseller, https://lynvn.com/collections/lyn-superstar, https://lynvn.com/collections/lyn-infinite, https://lynvn.com/collections/lyn-infinite-men and https://lynvn.com/pages/our-history and 7 others took over 3 s to send their HTML from our server.

Content and conversion

3 to fix58

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

  • 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 353 words of copy

Privacy and tracking

1 to fix
  • 8 trackers load before any consent

    8

    Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Hotjar and Klaviyo and 3 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.

  • 23 cookies set on arrival

    23

    Opening the homepage sets 23 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.

  • 38 other companies contacted

    Loading the homepage contacts 38 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
