vitruline.com website review

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.2 s.

Your mobile performance score is 87. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, Klaviyo and Shopify and others), adding 771 KiB and 553 ms of main-thread time.

About 265 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.

Google Tag Manager costs a phone 313 ms of main-thread work and 332 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.

4 long tasks block the main thread while loading, the longest for 276 ms. During a long task the page ignores taps.

About 17 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.

3 KiB could be saved by minifying JavaScript.

3 images could be 38 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 26 KiB JavaScript that modern phones do not need.

5 files are served with short cache lifetimes, so returning visitors download them again (14 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 9.5 s. Good is under 3.8 s.

Your largest element takes 3.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Vitruline”.

Scripts block taps and scrolling for 261 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.

1 image (100 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 0.51 g of CO₂e: 60.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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: 2 elements on the page fail this check, rated moderate by axe-core.

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your title is only 24 characters: “Vitruvin NMN Supplements”. Between 30 and 65 characters leaves room to say what you do and for whom.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

The homepage links to 84 pages on vitruline.com and 8 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.

There is no https://vitruline.com/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://vitruline.com/collections/all-products has no meta description, so Google writes the search snippet from whatever text it finds.

https://vitruline.com/collections/all-products has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 31 found) and read each the way a search engine does.

3 errors were logged to the browser console while the page loaded, for example “Invalid left-hand side in assignment”.

Social proof on the homepage: 1 testimonial or review block. Pairing it with named testimonials or customer logos makes it far more convincing.

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 801 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 2 mores (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 14 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 27 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
