hadrian.org website review

A phone's processor spends 4.4 s on main-thread work while loading, 2.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 81. Pages that score under 90 lose visitors before the first paint.

5 third-party services load with your homepage (Google Tag Manager, cdn-cookieyes.com and sanity.io and others), adding 8.0 MB and 180 ms of main-thread time.

sanity.io costs a phone 0 ms of main-thread work and 6.9 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.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 500 ms.

About 392 KiB of JavaScript is downloaded but never used on this page.

6 long tasks block the main thread while loading, the longest for 346 ms. During a long task the page ignores taps.

Unpkg costs a phone 0 ms of main-thread work and 803 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 12 KiB JavaScript that modern phones do not need.

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 9.7 s. Good is under 3.8 s.

Scripts block taps and scrolling for 577 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 5.5 s (Speed Index). Good is under 3.4 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 9.0 MB in 79 requests on a phone: media 6.7 MB (1), scripts 915 KiB (35) and other files 860 KiB (5). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 2.56 g of CO₂e: 307.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Your title is only 27 characters: “AI-Aware Biodefense | Blog.”. Between 30 and 65 characters leaves room to say what you do and for whom.

The homepage links to 11 pages on hadrian.org and 1 external page.

https://www.hadrian.org/team and https://www.hadrian.org/partners have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

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

2 errors were logged to the browser console while the page loaded, for example “Uncaught Error: Looks like your website URL has changed. To ensure the proper functioning of your banner, update the re…”.

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 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.

The homepage has only about 174 words of visible text; thin pages give Google and first-time buyers little to go on.

There is no form on the homepage, so every lead has to click through to another page first.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

Before a visitor clicks anything, the page loads Google Analytics and Google Tag Manager (measured from a US location before any click). A consent tool (CookieYes) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 2 cookies (measured from a US location before any click).

Loading the homepage contacts 6 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
