centizen.com website review

68 files are served with short cache lifetimes, so returning visitors download them again (1.7 MB).

Your mobile performance score is 75. Pages that score under 90 lose visitors before the first paint.

14 images could be 314 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 600 ms faster on a phone.

About 50 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.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

5 third-party services load with your homepage (clutch.co, JSDelivr CDN and Cloudflare CDN and others), adding 476 KiB and 37 ms of main-thread time.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

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 5.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Build Faster with Scalable Digital Engineering With 22+ yea…”.

Real visitors wait 2.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

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

Real visitors wait 1.3 s for your server to start answering (75th percentile). Good is under 800 ms.

The page becomes fully interactive after 5.9 s. Good is under 3.8 s.

Visually, the page fills in at 4.2 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.1 s to 1.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.2 MB in 82 requests on a phone: images 1.7 MB (64), fonts 371 KiB (6) and stylesheets 68 KiB (6). Under 2 MB keeps phones on slow connections fast.

12 images (1.1 MB) 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.

14 images further down the page (1.1 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.63 g of CO₂e: 75.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

No XML sitemap at https://centizen.com/sitemap-index.xml, so Google discovers your pages only by following links.

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

The homepage links to 160 pages on centizen.com and 13 external pages.

We fetched 15 pages linked from your homepage (of 97 found) and read each the way a search engine does.

1 image is served at too low a resolution for sharp phone screens.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

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

X-XSS-Protection is set to “1”; the header is deprecated and can introduce bugs. Use 0 or remove it.

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

centizen.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.

centizen.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.

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.

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

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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

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 1,122 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 1 cookie, 1 of them by other companies (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 6 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
