sdcclinical.com website review

About 527 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.3 s faster on a phone.

19 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

50 files are served with short cache lifetimes, so returning visitors download them again (287 KiB).

Your mobile performance score is 61. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, hsappstatic.net and Hubspot and others), adding 1.2 MB and 733 ms of main-thread time.

Google Tag Manager costs a phone 359 ms of main-thread work and 644 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.

A phone's processor spends 2.1 s on main-thread work while loading, 1.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

hsappstatic.net costs a phone 144 ms of main-thread work and 378 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 182 ms. During a long task the page ignores taps.

Polyfills for old browsers add 14 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.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Your largest element takes 8.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Homepage Hero_CRO and AI Technology_Man”.

The page becomes fully interactive after 12.2 s. Good is under 3.8 s.

The layout shifts by 0.152 while loading, so content jumps under the reader's thumb. Good is under 0.1.

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

Scripts block taps and scrolling for 278 ms in total while the page loads. Good is under 200 ms.

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

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

By the Sustainable Web Design model, a visit to your homepage emits about 0.46 g of CO₂e: 55.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

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

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

The homepage links to 92 pages on sdcclinical.com and 13 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no https://sdcclinical.com/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.

We fetched 15 pages linked from your homepage (of 20 found) and read each the way a search engine does.

3 of 7 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

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

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 787 words of visible text.

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

Opening the homepage sets 13 cookies (measured from a US location before any click).

Loading the homepage contacts 22 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
