cornerstone.com website review

7 images could be 1.5 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 3.9 s faster on a phone.

About 307 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.2 s faster on a phone.

Your mobile performance score is 67. Pages that score under 90 lose visitors before the first paint.

11 files block the first paint until they finish downloading. Deferring or inlining them could save about 950 ms.

About 118 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

6 third-party services load with your homepage (Optanon, Google Tag Manager and AddToAny and others), adding 421 KiB and 211 ms of main-thread time.

8 files are served with short cache lifetimes, so returning visitors download them again (81 KiB).

5 long tasks block the main thread while loading, the longest for 76 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 9 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.

Your largest element takes 21.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 21.9 s. Good is under 3.8 s.

Visually, the page fills in at 5.9 s (Speed Index). Good is under 3.4 s.

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

1 image have no width and height attributes, so the layout jumps as each one loads.

Your homepage downloads 6.6 MB in 52 requests on a phone: images 5.1 MB (14), fonts 792 KiB (6) and scripts 564 KiB (9). 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 (2.4 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.

By the Sustainable Web Design model, a visit to your homepage emits about 1.88 g of CO₂e: 225.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Some lists contain elements other than list items, which screen readers announce wrongly.

Some list items are not inside a list.

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

The skip-link target should exist and be focusable: 1 element on the page fails this check, rated moderate by axe-core.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h2 → h4, h3 → h6 and h3 → h6), which makes the page harder to scan with a screen reader.

Elements with visible text labels do not have matching accessible names. (1 element).

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

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

The homepage links to 102 pages on cornerstone.com and 15 external pages.

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.

We fetched 15 pages linked from your homepage (of 76 found) and read each the way a search engine does.

Large scripts ship without source maps.

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.

cornerstone.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.

cornerstone.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 testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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 3,857 words of visible text.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 3 cookies (measured from a US location before any click).

Loading the homepage contacts 9 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
