cosara.it website review

About 452 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.4 s faster on a phone.

Your mobile performance score is 66. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, posthog.com and Shopify and others), adding 1.2 MB and 751 ms of main-thread time.

19 files are served with short cache lifetimes, so returning visitors download them again (355 KiB).

Google Tag Manager costs a phone 329 ms of main-thread work and 514 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.

13 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

A phone's processor spends 2.2 s on main-thread work while loading, 1.4 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Polyfills for old browsers add 29 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

8 long tasks block the main thread while loading, the longest for 145 ms. During a long task the page ignores taps.

3 images could be 91 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

17 KiB JavaScript is shipped twice across bundles.

7 KiB could be saved by minifying JavaScript.

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

Your largest element takes 9.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 12.8 s. Good is under 3.8 s.

The first text or image appears after 2.9 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 4.6 s (Speed Index). Good is under 3.4 s.

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

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 2.5 MB in 200 requests on a phone: scripts 1.3 MB (67), images 1.0 MB (52) and stylesheets 92 KiB (35). Under 2 MB keeps phones on slow connections fast.

2 images (122 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.70 g of CO₂e: 84.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

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

No XML sitemap at https://cosara.it/sitemap.xml, so Google discovers your pages only by following links.

The homepage links to 125 pages on cosara.it and 6 external pages.

There is no https://cosara.it/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

https://cosara.it/customer_authentication/redirect has no <title>, so Google invents the link text in results.

https://cosara.it/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://cosara.it/customer_authentication/redirect and https://cosara.it/policies/shipping-policy have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://cosara.it/products/flash-by-sweet-muffin, whose canonical is https://cosara.it/products/flash-by-luna. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://cosara.it/customer_authentication/redirect has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 55 found) and read each the way a search engine does.

8 of 29 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

12 images are served at too low a resolution for sharp phone screens.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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 460 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Microsoft Clarity and 1 more (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.
