cellebrite.com website review

The page has 3,602 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

2 images could be 2.4 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

40 files are served with short cache lifetimes, so returning visitors download them again (1.1 MB).

Your mobile performance score is 79. Pages that score under 90 lose visitors before the first paint.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 950 ms.

About 611 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.

3 third-party services load with your homepage (Google Tag Manager, Cookiebot and Google Fonts), adding 405 KiB and 234 ms of main-thread time.

Polyfills for old browsers add 29 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

The HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.

About 136 KiB of CSS is downloaded but never applied on this page.

4 long tasks block the main thread while loading, the longest for 106 ms. During a long task the page ignores taps.

92 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.

Real visitors see the first content after 3.7 s (75th percentile). Good is under 1.8 s.

Real visitors wait 3.8 s for your server to start answering (75th percentile). Good is under 800 ms.

The page becomes fully interactive after 10.2 s. Good is under 3.8 s.

Visually, the page fills in at 6.8 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.3 s on a phone. Good is under 1.8 s.

Real visitors wait 4.0 s for the largest content to appear (75th percentile). Good is under 2.5 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 text “The trusted platform for investigations and intelligence-le…”. Most of its time is element render delay (2.3 s).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 125 ms to 148 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 4.5 s to 4.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

2 images weigh 3.7 MB together. On a phone connection a single image that size takes seconds.

Your homepage downloads 4.3 MB in 53 requests on a phone: images 2.5 MB (7), scripts 1.2 MB (30) and fonts 271 KiB (9). Under 2 MB keeps phones on slow connections fast.

5 images are downloaded at several times the size a phone draws them, for example Image-3.png.webp at 1,920 px wide, shown at 290 px. Resized copies would save about 3.6 MB.

1 image (402 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 1.21 g of CO₂e: 145.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

50 visible links have no text or label, so screen readers cannot say where they go.

The homepage links to 291 pages on cellebrite.com and 39 external pages.

Your robots.txt lets ChatGPT search (OAI-SearchBot) and Perplexity (PerplexityBot) read the homepage but closes other sections to them, so answers about those pages can't cite you.

https://cellebrite.com/en/solutions and https://cellebrite.com/en/solutions/roles all use the title “Digital Forensic Solutions by Role - Cellebrite”. Search engines can't tell which page to show for a search, so each competes with the others.

https://cellebrite.com/en/solutions and https://cellebrite.com/en/solutions/roles use the same meta description. A description written for each page earns more clicks.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://cellebrite.com/en/solutions, whose canonical is https://cellebrite.com/en/solutions/roles. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://cellebrite.com/en/solutions, https://cellebrite.com/en/solutions/roles, https://cellebrite.com/en/solutions/roles/analyst, https://cellebrite.com/en/solutions/roles/cellebrite-enterprise-solutions-for-directors-of-it, https://cellebrite.com/en/solutions/roles/examiner and https://cellebrite.com/en/solutions/roles/intel-analyst and 5 others took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 118 found) and read each the way a search engine does.

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.

Your longest form asks for 35 fields (18 required). Every extra field lowers completion.

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 903 words of visible text.

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

Opening the homepage sets 5 cookies (measured from a US location before any click).

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