colagenova.com website review

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.0 s.

7 third-party services load with your homepage (Shopify, Klaviyo and Google Tag Manager and others), adding 2.9 MB and 441 ms of main-thread time.

Shopify costs a phone 273 ms of main-thread work and 2.4 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.

About 484 KiB of JavaScript is downloaded but never used on this page.

A phone's processor spends 3.6 s on main-thread work while loading, 983 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 2,530 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

7 images could be 197 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

8 long tasks block the main thread while loading, the longest for 167 ms. During a long task the page ignores taps.

About 87 KiB of CSS is downloaded but never applied on this page.

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

6 files are served with short cache lifetimes, so returning visitors download them again (13 KiB).

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.

2 KiB could be saved by minifying CSS.

The page becomes fully interactive after 11.6 s. Good is under 3.8 s.

Visually, the page fills in at 4.9 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 4.6 MB in 292 requests on a phone: media 1.5 MB (1), scripts 1.1 MB (140) and other files 971 KiB (101). Under 2 MB keeps phones on slow connections fast.

4 images (171 KiB) 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.

4 images further down the page (107 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.29 g of CO₂e: 155.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA toggle fields must have an accessible name: 2 elements on the page fail this check, rated serious by axe-core.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

All page content should be contained by landmarks: 10 elements on the page fail this check, rated moderate by axe-core.

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

Headings skip levels (h2 → h6 and h2 → h4), which makes the page harder to scan with a screen reader.

No meta description, so Google writes its own snippet from whatever text it finds.

There are 2 <h1> headlines (“Colagenova” and “El colágeno que funciona.”). One clear main headline is easier for people and search engines.

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

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

The homepage links to 122 pages on colagenova.com and 3 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

https://colagenova.com/collections/salud-articular has no meta description, so Google writes the search snippet from whatever text it finds.

https://colagenova.com/products/colagenova-movility and https://colagenova.com/products/colagenova-movility-bolsa-780g use the same meta description. A description written for each page earns more clicks.

https://colagenova.com/collections/salud-articular has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 36 found) and read each the way a search engine does.

3 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_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.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

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 388 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel (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.

Opening the homepage sets 12 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 21 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
