celerity.com website review

36 files are served with short cache lifetimes, so returning visitors download them again (10.1 MB).

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

5 third-party services load with your homepage (Google Tag Manager, Vidyard and Optanon and others), adding 9.5 MB and 700 ms of main-thread time.

About 472 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 920 ms faster on a phone.

3 images could be 1.4 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Vidyard costs a phone 184 ms of main-thread work and 8.9 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 64 (desktop: 96). Pages that score under 90 lose visitors before the first paint.

About 146 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 770 ms faster on a phone.

Google Tag Manager costs a phone 383 ms of main-thread work and 372 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.

9 long tasks block the main thread while loading, the longest for 161 ms. During a long task the page ignores taps.

Desktop scores 96 but mobile only 64. A gap that wide usually means heavy scripts and images that hit phones hardest.

Polyfills for old browsers add 9 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.

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 7.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “randstad digital: powering your digital ambition.”.

The page becomes fully interactive after 13.3 s. Good is under 3.8 s.

Visually, the page fills in at 6.6 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 94 ms to 129 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 1.9 s to 2.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.3 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.2 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 268 ms in total while the page loads. Good is under 200 ms.

Your homepage downloads 11.6 MB in 76 requests on a phone: images 10.1 MB (12), scripts 1.1 MB (37) and stylesheets 141 KiB (4). Under 2 MB keeps phones on slow connections fast.

2_1.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

1 image (40 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 3.28 g of CO₂e: 393.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Some lists contain elements other than list items, which screen readers announce wrongly.

ARIA role should be appropriate for the element: 2 elements on the page fail this check, rated minor by axe-core.

Alternative text of images should not be repeated as text: 1 element on the page fails this check, rated minor by axe-core.

Elements with visible text labels do not have matching accessible names. (1 element).

Structured data found (Organization, WebPage and WebSite) but with 2 problems, for example “Organization: missing name”.

10 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 48 pages on celerity.com and 8 external pages.

Your Organization JSON-LD is missing name, url, logo, sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

There is no /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.

/ and /fr all use the title “Talent Focused Digital Enablement Solutions | Randstad Digital”. Search engines can't tell which page to show for a search, so each competes with the others.

Your homepage links to 1 page by a URL that isn't its canonical one, for example /fr, whose canonical is /fr/home. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/contact-us has 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 15 pages linked from your homepage (of 30 found) and read each the way a search engine does.

2 of 8 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

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

Opening https://celerity.com goes through 3 redirects before the homepage loads.

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.

randstaddigital.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

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

Social proof on the homepage: 1 customer or partner logo. Pairing it with named testimonials or customer logos makes it far more convincing.

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.

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.

The homepage carries about 515 words of visible text.

celerity.com has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

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 Tag Manager (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 2 cookies, 1 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 8 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
