hadrian.io website review

23 files block the first paint until they finish downloading. Deferring or inlining them could save about 5.8 s.

About 680 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.9 s faster on a phone.

A phone's processor spends 13.3 s on main-thread work while loading, 4.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 26 (desktop: 54). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

The page has 4,482 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (website-files.com, Google Tag Manager and Hotjar and others), adding 3.6 MB and 1.9 s of main-thread time.

31 files are served with short cache lifetimes, so returning visitors download them again (2.0 MB).

20 long tasks block the main thread while loading, the longest for 1.4 s. During a long task the page ignores taps.

website-files.com costs a phone 562 ms of main-thread work and 2.8 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.

Google Tag Manager costs a phone 426 ms of main-thread work and 289 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.

Hotjar costs a phone 320 ms of main-thread work and 64 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.

Facebook costs a phone 257 ms of main-thread work and 220 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.

About 68 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.

Polyfills for old browsers add 54 KiB JavaScript that modern phones do not need.

6 images could be 45 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Desktop scores 54 but mobile only 26. A gap that wide usually means heavy scripts and images that hit phones hardest.

9 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.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

The first text or image appears after 8.6 s on a phone. Good is under 1.8 s.

Your largest element takes 15.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Know your attack surface,”.

Scripts block taps and scrolling for 5.1 s in total while the page loads. Good is under 200 ms.

The page becomes fully interactive after 26.3 s. Good is under 3.8 s.

Visually, the page fills in at 11.4 s (Speed Index). Good is under 3.4 s.

Real visitors wait 219 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors see the first content after 2.4 s (75th percentile). Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-10-10, real Chrome visitors' tap response (inp) went from 115 ms to 137 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.5 MB in 138 requests on a phone: scripts 2.3 MB (58), media 1.5 MB (4) and fonts 330 KiB (6). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.27 g of CO₂e: 152.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

The homepage links to 171 pages on hadrian.io and 8 external pages.

We fetched 15 pages linked from your homepage (of 80 found) and read each the way a search engine does.

2 of 6 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “Error: <svg> attribute height: Expected length, "auto".”.

Large scripts ship without source maps.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

1 link go through two or more redirects, for example https://app.hadrian.io/.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

hadrian.io has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

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

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 1,251 words of visible text.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Hotjar and HubSpot and 3 mores (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 10 cookies (measured from a US location before any click).

Loading the homepage contacts 43 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
