3cisd.com website review

About 786 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 6.8 s faster on a phone.

8 files are served with short cache lifetimes, so returning visitors download them again (589 KiB).

8 images could be 341 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.8 s faster on a phone.

48 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.9 s.

About 224 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.1 s faster on a phone.

Your mobile performance score is 48. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

7 third-party services load with your homepage (Google CDN, cloudfront.net and Google Tag Manager and others), adding 1.6 MB and 836 ms of main-thread time.

Google CDN costs a phone 378 ms of main-thread work and 736 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.

cloudfront.net costs a phone 292 ms of main-thread work and 588 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 3.0 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

12 long tasks block the main thread while loading, the longest for 177 ms. During a long task the page ignores taps.

Polyfills for old browsers add 20 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

19 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.

4 KiB JavaScript is shipped twice across bundles.

The first text or image appears after 10.5 s on a phone. Good is under 1.8 s.

Your largest element takes 24.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “3CHome - Slide 2”.

The page becomes fully interactive after 24.4 s. Good is under 3.8 s.

Visually, the page fills in at 10.9 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 325 ms in total while the page loads. Good is under 200 ms.

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.

Your homepage downloads 4.7 MB in 152 requests on a phone: images 2.0 MB (20), scripts 1.7 MB (67) and other files 356 KiB (6). Under 2 MB keeps phones on slow connections fast.

1 image (74 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.

1 image further down the page (74 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.34 g of CO₂e: 161.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

All page content should be contained by landmarks: 19 elements on the page fail this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 2 elements on the page fail this check, rated moderate by axe-core.

Document should not have more than one contentinfo landmark: 1 element on the page fails this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

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

2 form fields have no label, so screen readers announce an empty box and autofill guesses.

ARIA role should be appropriate for the element: 4 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h3 → h5), which makes the page harder to scan with a screen reader.

No meta description, so Google writes its own snippet from whatever text it finds.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

There are 2 <h1> headlines (“DEB CHILDRESS, PHD” and “Chief of Research and Learning Content”). One clear main headline is easier for people and search engines.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

1 link has no real href, so search engines can't follow it.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 13 pages on 3cisd.com and 2 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 /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.

/behavior-change, /professional-development, /assessment-reporting, /resource-center, /implementation-support and /case-studies and 4 others have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 10 pages linked from your homepage and read each the way a search engine does.

24 of 53 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://dm0gz550769cd.cloudfront.net/published-assets/production/20261022123617/build/js/s…”.

1 link from your homepage to your own site is broken, for example https://3cisd.com/cdn-cgi/l/email-protection (404).

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

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

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

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

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.

3cisd.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.

3cisd.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.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust 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 1,319 words of visible text.

DMARC is set to p=none, so mail pretending to be 3cisd.com is still delivered. Reports are on, so moving to quarantine is the next step.

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 Analytics and Google Tag Manager (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 12 cookies (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 8 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
