cosmerna.com website review

A phone's processor spends 13.3 s on main-thread work while loading, 2.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (YouTube, Shopify and avada.io and others), adding 2.7 MB and 1.0 s of main-thread time.

Your mobile performance score is 72. Pages that score under 90 lose visitors before the first paint.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 950 ms.

YouTube costs a phone 528 ms of main-thread work and 1.0 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 585 KiB of JavaScript is downloaded but never used on this page.

Shopify costs a phone 357 ms of main-thread work and 1.3 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.

9 long tasks block the main thread while loading, the longest for 294 ms. During a long task the page ignores taps.

The page has 2,722 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

7 images could be 184 KiB 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.

About 156 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.

7 files are served with short cache lifetimes, so returning visitors download them again (35 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.

The page becomes fully interactive after 23.6 s. Good is under 3.8 s.

Visually, the page fills in at 12.7 s (Speed Index). Good is under 3.4 s.

Your largest element takes 3.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Scripts block taps and scrolling for 357 ms in total while the page loads. Good is under 200 ms.

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 5.0 MB in 526 requests on a phone: scripts 1.9 MB (222), other files 1.3 MB (210) and images 1.1 MB (41). Under 2 MB keeps phones on slow connections fast.

d7b2b9bbc42641eaa5d573cf8e20aa1b.thumbnail.0000000000.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

2 images further down the page (41 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 1.43 g of CO₂e: 171.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 element hidden from screen readers can still receive keyboard focus.

1 frame has no title, so screen-reader users cannot tell what it contains.

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

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

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

Your title is only 8 characters: “CosmeRNA”. Between 30 and 65 characters leaves room to say what you do and for whom.

Your meta description is 259 characters; Google truncates after about 160, so the end of your pitch is cut.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

The homepage links to 54 pages on cosmerna.com and 30 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

The HTML your server sends has 666 of the 1,685 words a browser shows. AI crawlers don't run JavaScript, so they miss the rest.

Your homepage links to https://www.cosmerna.com/en-us/blogs/cosmerna-insights/announcement, which answers with an error. Visitors hit a dead end and search engines drop it.

We fetched 15 pages linked from your homepage (of 33 found) and read each the way a search engine does.

5 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

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

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

Chrome logged issues while loading the page (“Cookie”).

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

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

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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 1,685 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). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 10 cookies, 1 of them by other companies (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 26 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
