adeia.com website review

9 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.0 s.

293 KiB could be saved by minifying JavaScript.

25 files are served with short cache lifetimes, so returning visitors download them again (10.8 MB).

6 third-party services load with your homepage (website-files.com, JSDelivr CDN and cloudfront.net and others), adding 12.3 MB and 381 ms of main-thread time.

website-files.com costs a phone 153 ms of main-thread work and 11.9 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.

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

About 62 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

About 40 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

7 KiB could be saved by minifying CSS.

7 images could be 155 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

1 long task block the main thread while loading, the longest for 76 ms. During a long task the page ignores taps.

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.

Your largest element takes 7.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The first text or image appears after 4.1 s on a phone. Good is under 1.8 s.

Real visitors see the first content after 1.9 s (75th percentile). Good is under 1.8 s.

Real visitors wait 865 ms for your server to start answering (75th percentile). Good is under 800 ms.

The page becomes fully interactive after 7.2 s. Good is under 3.8 s.

Visually, the page fills in at 4.1 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 89 ms to 84 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 12.3 MB in 62 requests on a phone: media 10.7 MB (2), images 888 KiB (20) and scripts 538 KiB (29). Under 2 MB keeps phones on slow connections fast.

3 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 3.49 g of CO₂e: 419.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

8 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: 15 elements on the page fail this check, rated moderate by axe-core.

Banner landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Document should not have more than one banner landmark: 1 element on the page fails this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

3 form fields have no label, so screen readers announce an empty box and autofill guesses.

ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (h1 → h4, h2 → h4 and h2 → h4), which makes the page harder to scan with a screen reader.

Structured data found (Organization) but with 1 problem, for example “Organization: url is not an absolute URL ("/")”.

The homepage links to 47 pages on adeia.com and 6 external pages.

/all-upcoming-events and /newsroom have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 24 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

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

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.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

adeia.com 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.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

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

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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 255 words of visible text.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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.

Opening the homepage sets 2 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 7 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
