ducadelcosma.us website review

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.5 s.

A phone's processor spends 7.1 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

13 images could be 7.2 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

8 third-party services load with your homepage (alia-prod.com, Shopify and Klaviyo and others), adding 8.2 MB and 922 ms of main-thread time.

alia-prod.com costs a phone 523 ms of main-thread work and 7.5 MB 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.

Your mobile performance score is 77. Pages that score under 90 lose visitors before the first paint.

Shopify costs a phone 222 ms of main-thread work and 394 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.

The page has 1,777 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

20 files are served with short cache lifetimes, so returning visitors download them again (229 KiB).

9 long tasks block the main thread while loading, the longest for 194 ms. During a long task the page ignores taps.

About 33 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.

About 128 KiB of JavaScript is downloaded but never used on this page.

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

Polyfills for old browsers add 29 KiB JavaScript that modern phones do not need.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

The page becomes fully interactive after 12.3 s. Good is under 3.8 s.

Your largest element takes 4.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Visually, the page fills in at 5.8 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.4 s on a phone. Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 93 ms to 89 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 10.4 MB in 410 requests on a phone: images 8.1 MB (29), other files 1.0 MB (203) and scripts 986 KiB (152). Under 2 MB keeps phones on slow connections fast.

2 images weigh 6.8 MB together. On a phone connection a single image that size takes seconds.

2 images are downloaded at several times the size a phone draws them, for example e0e83648ab2a77a4.webp at 2,160 px wide, shown at 234 px. Resized copies would save about 6.1 MB.

1 image (127 KiB) is 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.

By the Sustainable Web Design model, a visit to your homepage emits about 2.94 g of CO₂e: 352.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

Some list items are not inside a list.

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

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. (1 element).

Your title is only 28 characters: “Golf Shoes by Duca del Cosma”. Between 30 and 65 characters leaves room to say what you do and for whom.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 156 pages on ducadelcosma.us and 6 external pages.

https://ducadelcosma.us/collections/all-mens-golf-shoes, https://ducadelcosma.us/collections/mens-shoes-best-sellers and https://ducadelcosma.us/collections/all-womens-golf-shoes have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 58 found) and read each the way a search engine does.

14 of 50 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_TUNNEL_CONNECTION_FAILED”.

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

Social proof on the homepage: 36 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 265 words of visible text.

Opening the homepage sets 20 cookies (measured from a US location before any click).

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.

Loading the homepage contacts 36 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
