northmuseum.org website review

About 808 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.3 s faster on a phone.

26 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.6 s.

215 KiB could be saved by minifying JavaScript.

5 files are served with short cache lifetimes, so returning visitors download them again (190 KiB).

Your mobile performance score is 28 (desktop: 39). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 7.2 s on main-thread work while loading, 3.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

23 images could be 1.9 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 200 ms faster on a phone.

8 third-party services load with your homepage (Google Tag Manager, Facebook and blackbaudcdn.net and others), adding 1.1 MB and 1.6 s of main-thread time.

About 198 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.

Google Tag Manager costs a phone 686 ms of main-thread work and 424 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.

Facebook costs a phone 434 ms of main-thread work and 213 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.

blackbaudcdn.net costs a phone 400 ms of main-thread work and 316 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.

20 long tasks block the main thread while loading, the longest for 383 ms. During a long task the page ignores taps.

20 KiB could be saved by minifying CSS.

Polyfills for old browsers add 25 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.

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.

Your largest element takes 17.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image. Most of its time is resource load delay (7.0 s).

Visually, the page fills in at 14.5 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 5.9 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 17.2 s. Good is under 3.8 s.

Scripts block taps and scrolling for 2.0 s in total while the page loads. Good is under 200 ms.

Real visitors wait 893 ms for your server to start answering (75th percentile). Good is under 800 ms.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 86 ms to 87 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 1.8 s to 2.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 6.2 MB in 146 requests on a phone: images 4.0 MB (56), scripts 1.6 MB (48) and fonts 292 KiB (5). Under 2 MB keeps phones on slow connections fast.

manufacturing-hp-uai-1032x1032.png weighs 546 KiB. On a phone connection a single image that size takes seconds.

15 images (2.9 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.

7 images further down the page (1.5 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

5 images are downloaded at several times the size a phone draws them, for example manufacturing-hp-uai-1032x1032.png at 1,032 px wide, shown at 302 px. Resized copies would save about 369 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 1.75 g of CO₂e: 210.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

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

Headings skip levels (h1 → h4), which makes the page harder to scan with a screen reader.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

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

The homepage links to 108 pages on northmuseum.org and 5 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://northmuseum.org/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://northmuseum.org/calendar-events and https://northmuseum.org/calendar all use the title “Calendar Events - North Museum”. Search engines can't tell which page to show for a search, so each competes with the others.

https://northmuseum.org/calendar-events, https://northmuseum.org/buy-tickets, https://northmuseum.org/visit, https://northmuseum.org/calendar, https://northmuseum.org/group-visits-school-field-trips and https://northmuseum.org/plan-an-event and 1 other have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://northmuseum.org/calendar, whose canonical is https://northmuseum.org/calendar-events. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://northmuseum.org/visit/promotions-and-discounts, https://northmuseum.org/faq, https://northmuseum.org/exhibits/imagining-insects, https://northmuseum.org/collections and https://northmuseum.org/live-animal-room took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 45 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “gtag is not defined”.

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

Large scripts ship without source maps.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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.

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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 514 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and Mixpanel (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 (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.
