centinelamed.com website review

125 files are served with short cache lifetimes, so returning visitors download them again (4.7 MB).

About 1.2 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 9.8 s faster on a phone.

34 images could be 7.9 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 2.1 s faster on a phone.

39 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.7 s.

Your mobile performance score is 28. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.2 s on main-thread work while loading, 1.4 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (YouTube, steerhealth.io and userway.org and others), adding 2.5 MB and 1.0 s of main-thread time.

YouTube costs a phone 935 ms of main-thread work and 1.9 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.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 450 ms).

14 long tasks block the main thread while loading, the longest for 294 ms. During a long task the page ignores taps.

Polyfills for old browsers add 18 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

About 148 KiB of CSS is downloaded but never applied on this page.

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.

5 KiB could be saved by minifying CSS.

3 KiB could be saved by minifying JavaScript.

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 wait 4.4 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 2.4 s for your server to start answering (75th percentile). Good is under 800 ms.

Your largest element takes 55.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “FastTrackCareReserve Your ER Arrival…”.

Visually, the page fills in at 18.2 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 58.0 s. Good is under 3.8 s.

The layout shifts by 0.991 while loading, so content jumps under the reader's thumb. Good is under 0.1.

The first text or image appears after 4.7 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.5 s to 3.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 3.0 s (75th percentile). Good is under 1.8 s.

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

Scripts block taps and scrolling for 227 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 79 ms to 88 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 14.2 MB in 176 requests on a phone: images 11.1 MB (65), scripts 2.2 MB (45) and fonts 460 KiB (12). Under 2 MB keeps phones on slow connections fast.

20 images are downloaded at several times the size a phone draws them, for example DKA5STAR.png at 7,017 px wide, shown at 242 px. Resized copies would save about 6.9 MB.

7 images weigh 6.0 MB together. On a phone connection a single image that size takes seconds.

27 images (9.4 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.

25 images further down the page (9.0 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 4.02 g of CO₂e: 482.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

5 tap targets are too small or too close together to hit reliably with a finger.

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

ARIA toggle fields do not have accessible names (1 element).

1 form field has no label, so screen readers announce an empty box and autofill guesses.

There are 10 <h1> headlines (“FastTrackCare”, “Emergency Department Accreditation” and “MyChart Patient Portal Text Opt-In”). One clear main headline is easier for people and search engines.

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

Structured data found (AboutPage, ContactPage, Hospital and ImageObject) but with 8 problems, for example “WebSite: missing name”.

Open Graph is missing og:description, so shared links fall back to guesses.

The homepage links to 118 pages on centinelamed.com and 14 external pages.

/help-paying-your-bill took over 3 s to send its HTML from our server.

We fetched 15 pages linked from your homepage (of 44 found) and read each the way a search engine does.

11 of 26 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

5 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

7 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

Chrome logged issues while loading the page (“Cookie”).

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

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.

centinelamed.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.

centinelamed.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.

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

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 946 words of visible text.

centinelamed.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.

centinelamed.com has no SPF record, so mail servers can't tell which servers may send email as you. Your mail lands in spam more often, and anyone can send mail pretending to be you.

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.

centinelamed.com has no MX record, so it receives no email. SPF -all and DMARC reject still matter: they stop others sending mail as you.

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 (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 4 cookies, 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 16 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
