provasil.com website review

Your mobile performance score is 83. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, Facebook and TikTok and others), adding 1.5 MB and 668 ms of main-thread time.

About 422 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 492 ms of main-thread work and 553 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.

6 files are served with short cache lifetimes, so returning visitors download them again (250 KiB).

Shopify costs a phone 0 ms of main-thread work and 487 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.

Polyfills for old browsers add 35 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 200 ms faster on a phone.

2 images could be 227 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

7 long tasks block the main thread while loading, the longest for 173 ms. During a long task the page ignores taps.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 150 ms.

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

The page becomes fully interactive after 12.5 s. Good is under 3.8 s.

Your largest element takes 4.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Provasil - Powerful Cognitive Support”.

Scripts block taps and scrolling for 222 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.

2 images are downloaded at several times the size a phone draws them, for example Cognitive-Health-_-Sleep_0c20a620-03b7-408b-a546-00c311c7abb at 2,048 px wide, shown at 326 px. Resized copies would save about 290 KiB.

3 images further down the page (485 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 0.56 g of CO₂e: 66.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

All page content should be contained by landmarks: 4 elements on the page fail this check, rated moderate by axe-core.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

The homepage links to 18 pages on provasil.com and 9 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://provasil.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://provasil.com/products/provasil-reviews has no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 5 pages linked from your homepage and read each the way a search engine does.

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

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

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage carries about 733 words of visible text.

Before a visitor clicks anything, the page loads 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.

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