aspenpublishing.com website review

Sentry costs a phone 3.3 s of main-thread work and 76 KiB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

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

A phone's processor spends 12.4 s on main-thread work while loading, 7.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 17. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Sentry, Facebook and Google CDN and others), adding 1.4 MB and 4.8 s of main-thread time.

About 581 KiB of JavaScript is downloaded but never used on this page.

14 files are served with short cache lifetimes, so returning visitors download them again (574 KiB).

16 images could be 481 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

20 long tasks block the main thread while loading, the longest for 444 ms. During a long task the page ignores taps.

Facebook costs a phone 383 ms of main-thread work and 254 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.

Google CDN costs a phone 312 ms of main-thread work and 294 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.

The page has 1,586 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

About 75 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.

Polyfills for old browsers add 29 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.

2 KiB could be saved by minifying CSS.

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 page becomes fully interactive after 22.3 s. Good is under 3.8 s.

The layout shifts by 0.88 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Your largest element takes 7.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

Scripts block taps and scrolling for 1.6 s in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 6.4 s (Speed Index). Good is under 3.4 s.

For real visitors the layout shifts by 0.18 (75th percentile). Good is under 0.1.

The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.1 s to 1.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.9 MB in 408 requests on a phone: scripts 1.7 MB (98), other files 1.5 MB (244) and images 1.0 MB (27). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.40 g of CO₂e: 167.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Banner landmark should not be contained in another landmark: 2 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.

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.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

1 frame has no title, so screen-reader users cannot tell what it contains.

There are 8 <h1> headlines (“Aspen Publishing”, “Find the casebooks you need and the study aids yo…” and “The most trusted legal casebooks and study aids a…”). One clear main headline is easier for people and search engines.

The homepage links to 208 pages on aspenpublishing.com and 21 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description 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.

Your homepage links to /pages/practiceperfect-resources-for-students, which answers with an error. Visitors hit a dead end and search engines drop it.

/collections/shop-all, /collections/study-aids, /pages/aspen-access-program, /pages/aspen-learning-library-user-guides, /pages/connected-quizzing-resources-for-students and /pages/on-demand-print-companion and 4 others have no meta description, so Google writes the search snippet from whatever text it finds.

/collections/shop-all, /collections/study-aids, /pages/aspen-access-program, /pages/connected-quizzing-resources-for-students, /pages/on-demand-print-companion and /collections/custom-edition-textbooks and 2 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 103 found) and read each the way a search engine does.

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

2 errors were logged to the browser console while the page loaded, for example “Cart icon is not found”.

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

3 links from your homepage to your own site are broken, for example https://aspenpublishing.com/blogs/how-to-articles/aspen-access-educator-tutorial (503).

1 link to other sites is dead, for example https://twitter.com/AspenPublishing%22 (404).

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

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.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

aspenpublishing.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.

aspenpublishing.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.

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 611 words of visible text.

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