mycatdna.com website review

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

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

4 images could be 141 KiB 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.

About 398 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

About 75 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

Google Tag Manager costs a phone 291 ms of main-thread work and 499 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.

A phone's processor spends 2.0 s on main-thread work while loading, 742 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

7 third-party services load with your homepage (Google Tag Manager, Optanon and Shopify and others), adding 877 KiB and 431 ms of main-thread time.

6 files are served with short cache lifetimes, so returning visitors download them again (83 KiB).

19 KiB could be saved by minifying JavaScript.

4 long tasks block the main thread while loading, the longest for 124 ms. During a long task the page ignores taps.

Polyfills for old browsers add 9 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 11.2 s. Good is under 3.8 s.

Your largest element takes 4.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Product_MCD_edited_2.png”.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 96 ms to 113 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Visually, the page fills in at 5.6 s (Speed Index). Good is under 3.4 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' largest content (lcp) went from 1.2 s to 1.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.5 MB in 162 requests on a phone: scripts 1,011 KiB (43), other files 715 KiB (75) and images 393 KiB (22). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.70 g of CO₂e: 84.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

ARIA dialog and alertdialog nodes should have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

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

Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.

There are 2 <h1> headlines (“” and “All-in-one genetic testing for your breed”). One clear main headline is easier for people and search engines.

4 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 64 pages on mycatdna.com and 28 external pages.

Your homepage links to https://mycatdna.com/products/optimal-selection-feline, which answers with an error. Visitors hit a dead end and search engines drop it.

https://mycatdna.com/pages/cat-breeds, https://mycatdna.com/pages/our-science, https://mycatdna.com/pages/research, https://mycatdna.com/blogs/news, https://mycatdna.com/pages/compare and https://mycatdna.com/blogs/news/tagged/traits use the same meta description. A description written for each page earns more clicks.

We fetched 15 pages linked from your homepage (of 19 found) and read each the way a search engine does.

6 of 20 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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 721 words of visible text.

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

Opening the homepage sets 11 cookies (measured from a US location before any click).

Loading the homepage contacts 12 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
