Speed

12 to fix41
  • Render-blocking requests

    1.4 s

    24 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: 9.1 s

    A phone's processor spends 9.1 s on main-thread work while loading, 2.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • 3,084 HTML elements

    The page has 3,084 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

  • Improve image delivery

    7.9 MB

    61 images could be 7.9 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • 8 third-party services on the page

    8 third-party services load with your homepage (Google Tag Manager, Shopify and Klaviyo and others), adding 2.4 MB and 1.6 s of main-thread time.

  • Reduce unused JavaScript

    842 KiB

    About 842 KiB of JavaScript is downloaded but never used on this page.

  • Google Tag Manager adds 469 ms

    469 ms

    Google Tag Manager costs a phone 469 ms of main-thread work and 536 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

    100 ms · 346 KiB

    31 files are served with short cache lifetimes, so returning visitors download them again (346 KiB).

  • 20 long tasks on the main thread

    20 long tasks block the main thread while loading, the longest for 402 ms. During a long task the page ignores taps.

  • Shopify adds 307 ms

    307 ms

    Shopify costs a phone 307 ms of main-thread work and 587 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.

  • Klaviyo adds 298 ms

    298 ms

    Klaviyo costs a phone 298 ms of main-thread work and 628 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 CSS

    190 KiB

    About 190 KiB of CSS is downloaded but never applied on this page.

  • Legacy JavaScript

    76 KiB

    Polyfills for old browsers add 76 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

    9 KiB

    9 KiB could be saved by minifying JavaScript.

  • Minify CSS

    6 KiB

    6 KiB could be saved by minifying CSS.

  • 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.

1 checks passed
  • Server response: 9 ms

    9 ms

    Your server sent the HTML in 9 ms, well inside Google's 600 ms guideline.

Core Web Vitals

11 to fix67
  • Fails Core Web Vitals for real visitors

  • Largest content (LCP) got 32% slower for real visitors

    +32%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.7 s to 2.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

    2.3 s

    The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

4 checks passed
  • Real-user LCP: 2.3 s

Images and page weight

5 to fix18
  • Page weight: 19.7 MB in 509 requests

    19.7 MB

    Your homepage downloads 19.7 MB in 509 requests on a phone: images 9.7 MB (100), media 5.6 MB (15) and scripts 2.7 MB (170). Under 2 MB keeps phones on slow connections fast.

  • 37 images far larger than shown

    6.0 MB

    37 images are downloaded at several times the size a phone draws them, for example sepiia-polo-manga-larga-hombre-gris-oscuro-warm-plus-4_3e236 at 1,200 px wide, shown at 180 px. Resized copies would save about 6.0 MB.

  • 3 images over 500 KB

    3 images weigh 1.6 MB together. On a phone connection a single image that size takes seconds.

  • 28 images below the first screen load straight away

    28 images further down the page (5.5 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

  • 6 images in older formats

    6 images (2.7 MB) 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 5.6 g of CO₂ per visit

    5.59 g

    By the Sustainable Web Design model, a visit to your homepage emits about 5.59 g of CO₂e: 671.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Accessibility

13 to fixGoogle 7584
  • Unlabelled dropdowns

    5 dropdowns have no label.

  • 22 tap targets too small

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

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

  • 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.

  • Malformed lists

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

  • Scrollable region must have keyboard access (1 element)

    Scrollable region must have keyboard access: 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.

  • 8 buttons without a name

    8 buttons have no accessible name, so screen readers announce just “button”.

  • All page content should be contained by landmarks (19 elements)

    All page content should be contained by landmarks: 19 elements on the page fail this check, rated moderate by axe-core.

  • 9 form fields without a label

    9 form fields have no label, so screen readers announce an empty box and autofill guesses.

  • 1 link without text

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

  • ARIA role should be appropriate for the element (3 elements)

    ARIA role should be appropriate for the element: 3 elements on the page fail this check, rated minor by axe-core.

  • Alternative text of images should not be repeated as text (1 element)

    Alternative text of images should not be repeated as text: 1 element on the page fails this check, rated minor by axe-core.

  • Elements with visible text labels do not have matching accessible names.

    Elements with visible text labels do not have matching accessible names. (5 elements).

1 checks passed
  • 53 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 63 WCAG 2.2 A/AA and best-practice rules on the phone render: 53 passed and 10 failed. 4 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

Other pages

  • 2 pages without a meta description

    https://sepiia.com/en/pages/sepiia-club and https://sepiia.com/en/collections/warm-technology have no meta description, so Google writes the search snippet from whatever text it finds.
