stac.edu website review

About 393 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.0 s faster on a phone.

13 files are served with short cache lifetimes, so returning visitors download them again (199 KiB).

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

6 images could be 12.1 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 400 ms faster on a phone.

8 third-party services load with your homepage (Google Tag Manager, wpmucdn.com and Facebook and others), adding 1.1 MB and 1.0 s of main-thread time.

13 files block the first paint until they finish downloading. Deferring or inlining them could save about 800 ms.

Google Tag Manager costs a phone 671 ms of main-thread work and 659 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 2.2 s on main-thread work while loading, 903 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 54 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

8 long tasks block the main thread while loading, the longest for 196 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 50 ms faster on a phone.

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.

The first text or image appears after 9.3 s on a phone. Good is under 1.8 s.

Your largest element takes 18.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “IGNITE YOUR PASSION Ignite What’s Next. Imagine all you can…”.

The page becomes fully interactive after 19.3 s. Good is under 3.8 s.

Visually, the page fills in at 9.3 s (Speed Index). Good is under 3.4 s.

Real visitors wait 976 ms for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 341 ms in total while the page loads. Good is under 200 ms.

1 image 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' tap response (inp) went from 123 ms to 112 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.6 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 36.0 MB in 109 requests on a phone: media 21.4 MB (7), images 13.3 MB (31) and scripts 1.1 MB (24). Under 2 MB keeps phones on slow connections fast.

STAC-Campus-Aerial-new.jpg weighs 11.9 MB. On a phone connection a single image that size takes seconds.

1 image is downloaded at several times the size a phone draws it, for example STAC-Campus-Aerial-new.jpg at 13,500 px wide, shown at 342 px. Resized copies would save about 11.9 MB.

2 images (12.0 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.

2 images further down the page (12.0 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 10.20 g of CO₂e: 1223.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA roles used must conform to valid values: 1 element on the page fails this check, rated critical by axe-core.

Links must have discernible text: 5 elements on the page fail this check, rated serious by axe-core.

All page content should be contained by landmarks: 4 elements on the page fail this check, rated moderate by axe-core.

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

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

Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.

2 links have no real href, so search engines can't follow them.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

Your <h1> is empty.

The homepage links to 91 pages on stac.edu and 20 external pages.

Your Organization JSON-LD is missing logo, sameAs (social profiles) 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 https://stac.edu/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.

https://stac.edu/events has no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 57 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://stac.edu/.

6 of 16 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 “Failed to load resource: net::ERR_FAILED”.

Social proof on the homepage: 3 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach 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 511 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and The Trade Desk (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 11 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 28 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
