oxy.edu website review

8 images could be 4.7 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 4.6 s faster on a phone.

14 files block the first paint until they finish downloading. Deferring or inlining them could save about 6.0 s.

About 935 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.5 s faster on a phone.

Your mobile performance score is 34 (desktop: 51). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.4 s on main-thread work while loading, 2.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (YouTube, Google Tag Manager and Facebook and others), adding 1.9 MB and 1.7 s of main-thread time.

About 267 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 900 ms faster on a phone.

YouTube costs a phone 639 ms of main-thread work and 964 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.

14 files are served with short cache lifetimes, so returning visitors download them again (233 KiB).

Google Tag Manager costs a phone 605 ms of main-thread work and 630 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.

Polyfills for old browsers add 27 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.

Facebook costs a phone 257 ms of main-thread work and 240 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.

19 long tasks block the main thread while loading, the longest for 234 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 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.

2 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.

The first text or image appears after 11.6 s on a phone. Good is under 1.8 s.

Your largest element takes 23.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Oxy student and her professor”.

The page becomes fully interactive after 26.1 s. Good is under 3.8 s.

Visually, the page fills in at 11.6 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 972 ms in total while the page loads. Good is under 200 ms.

Real visitors wait 3.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.5 s to 2.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.9 s (75th percentile). Good is under 1.8 s.

Real visitors wait 942 ms for your server to start answering (75th percentile). Good is under 800 ms.

2 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' tap response (inp) went from 127 ms to 139 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 8.2 MB in 140 requests on a phone: images 5.1 MB (30), scripts 2.0 MB (29) and fonts 743 KiB (10). Under 2 MB keeps phones on slow connections fast.

2 images weigh 1.9 MB together. On a phone connection a single image that size takes seconds.

4 images are downloaded at several times the size a phone draws them, for example Thorne-Hall-26_1440x800.jpg at 1,440 px wide, shown at 390 px. Resized copies would save about 867 KiB.

5 images (2.5 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.

Thorne-Hall-26_1440x800.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 2.31 g of CO₂e: 277.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

6 buttons have no accessible name, so screen readers announce just “button”.

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

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

1 image has no alt text, which hurts accessibility and image search.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

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

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

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

The homepage links to 148 pages on oxy.edu and 28 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://www.oxy.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.

We fetched 15 pages linked from your homepage (of 123 found) and read each the way a search engine does.

19 of 67 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.

3 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://use.fontawesome.com/releases/v5.13.0/css/all.css' from origin 'https://www.oxy.edu…”.

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

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.

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

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

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 846 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and Microsoft Clarity and 1 more (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 14 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 28 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
