Speed

13 to fix35

  • Main-thread work: 15.2 s

    A phone's processor spends 15.2 s on main-thread work while loading, 8.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • Google Tag Manager adds 1.2 s

    1.2 s

    Google Tag Manager costs a phone 1.2 s of main-thread work and 1.4 MB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

  • Mobile performance score: 35

    35/100

    Your mobile performance score is 35. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

  • 5,965 HTML elements

    The page has 5,965 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

  • Improve image delivery

    450 ms · 2.4 MB

    49 images could be 2.4 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 450 ms faster on a phone.

  • 8 third-party services on the page

    8 third-party services load with your homepage (Google Tag Manager, Shopify and Cookiebot and others), adding 2.7 MB and 2.6 s of main-thread time.

  • Reduce unused JavaScript

    150 ms · 1.3 MB

    About 1.3 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

  • Render-blocking requests

    900 ms

    16 files block the first paint until they finish downloading. Deferring or inlining them could save about 900 ms.

  • 20 long tasks on the main thread

    20 long tasks block the main thread while loading, the longest for 726 ms. During a long task the page ignores taps.

  • Shopify adds 298 ms

    298 ms

    Shopify costs a phone 298 ms of main-thread work and 255 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.

  • Cookiebot adds 272 ms

    272 ms

    Cookiebot costs a phone 272 ms of main-thread work and 159 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 246 ms

    246 ms

    Klaviyo costs a phone 246 ms of main-thread work and 326 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.

  • xcottons.com adds 207 ms

    207 ms

    xcottons.com costs a phone 207 ms of main-thread work and 344 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

    185 KiB

    20 files are served with short cache lifetimes, so returning visitors download them again (185 KiB).

  • Reduce unused CSS

    150 ms · 29 KiB

    About 29 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

  • Legacy JavaScript

    27 KiB

    Polyfills for old browsers add 27 KiB JavaScript that modern phones do not need.

  • Duplicated JavaScript

    17 KiB

    17 KiB JavaScript is shipped twice across bundles.

  • 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: 19 ms

    19 ms

    Your server sent the HTML in 19 ms, well inside Google's 600 ms guideline.

Core Web Vitals

Images and page weight

1 to fix33

  • Page weight: 9.2 MB in 452 requests

    9.2 MB

    Your homepage downloads 9.2 MB in 452 requests on a phone: images 5.0 MB (97), scripts 3.0 MB (132) and other files 929 KiB (174). Under 2 MB keeps phones on slow connections fast.

  • About 2.6 g of CO₂ per visit

    2.61 g

    By the Sustainable Web Design model, a visit to your homepage emits about 2.61 g of CO₂e: 313.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Accessibility

5 to fixGoogle 9386

  • Delayed refresh under 20 hours must not be used (1 element)

    Delayed refresh under 20 hours must not be used: 1 element on the page fails this check, rated critical by axe-core.

  • 20 images without alt text

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

  • 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.

  • 5 text elements with low contrast

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

  • Headings should not be empty (1 element)

    Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

  • Headings skip levels

    Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.

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

    Elements with visible text labels do not have matching accessible names. (1 element).

1 checks passed

  • 20 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 23 WCAG 2.2 A/AA and best-practice rules on the phone render: 20 passed and 3 failed. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

1 to fixGoogle 8598

  • llms.txt published

Other pages

1 to fix95

  • 10 pages without an H1

    https://dyucycle.com/pages/holiday-sale, https://dyucycle.com/products/dyu-m20-all-terrain-long-range-electric-bike, https://dyucycle.com/products/dyu-sp1-20-inch-removable-power-bank-folding-ebike, https://dyucycle.com/products/dyu-ux-bmx-20-inch-fat-tire-electric-bike, https://dyucycle.com/products/dyu-d3s-14-inch-mini-folding-electric-bike and https://dyucycle.com/products/dyu-t1-pedal-assist-torque-sensor-electric-bike and 4 others have no <h1> headline, so visitors and search engines get no clear main topic.

  • 5 pages slow to respond

    https://dyucycle.com/products/dyu-d3s-14-inch-mini-folding-electric-bike, https://dyucycle.com/products/dyu-t1-pedal-assist-torque-sensor-electric-bike, https://dyucycle.com/products/c6-26-inch-city-electric-bike, https://dyucycle.com/products/dyu-c9-20-inch-long-range-ebike and https://dyucycle.com/products/dyu-c2-16-inch-full-folding-electric-bike took over 3 s to send their HTML from our server.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 53 found) and read each the way a search engine does.

6 checks passed

Best practices

1 to fixGoogle 9692

  • 2 JavaScript errors while loading

    2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 429 ()”.

1 checks passed

  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

5 to fix63

  • 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: 12 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

  • A 21-field form

    Your longest form asks for 21 fields (0 required). Every extra field lowers completion.

  • 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.

  • Only about 10 words

    The homepage has only about 10 words of visible text; thin pages give Google and first-time buyers little to go on.

3 checks passed

  • 38 calls to action

    The homepage has 38 calls to action, for example “Buy It Now”, “Shop now” and “Shop Now”.

  • Analytics in place

    Analytics detected: Google Tag Manager and Google Analytics.

  • Risk reducer mentioned

    A guarantee or risk reducer (money-back, free trial, no credit card or similar) is mentioned on the page.

Privacy and tracking

  • 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.

  • 1 other company contacted

    Loading the homepage contacts 1 host run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

1 checks passed

  • No known trackers before consent

    No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).
