semperis.com website review

3 images could be 1.8 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 9.6 s faster on a phone.

About 802 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 5.3 s faster on a phone.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.9 s.

17 files are served with short cache lifetimes, so returning visitors download them again (218 KiB).

Your mobile performance score is 45. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google CDN, Google Tag Manager and Accessibe Accessibility Overlay and others), adding 1.6 MB and 875 ms of main-thread time.

Polyfills for old browsers add 35 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 450 ms faster on a phone.

About 105 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

Google CDN costs a phone 284 ms of main-thread work and 736 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 Tag Manager costs a phone 270 ms of main-thread work and 370 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 2.6 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 1,604 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

9 long tasks block the main thread while loading, the longest for 197 ms. During a long task the page ignores taps.

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 9.1 s on a phone. Good is under 1.8 s.

Your largest element takes 34.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 34.8 s. Good is under 3.8 s.

Visually, the page fills in at 10.2 s (Speed Index). Good is under 3.4 s.

Real visitors see the first content after 2.2 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.3 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 419 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.9 s to 2.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 6.3 MB in 136 requests on a phone: images 3.7 MB (45), scripts 1.8 MB (35) and other files 426 KiB (43). Under 2 MB keeps phones on slow connections fast.

2 images weigh 3.5 MB together. 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 image-background-lightning-stirke-1920x1169.png at 1,920 px wide, shown at 390 px. Resized copies would save about 1.0 MB.

2 images (3.5 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.

1 image further down the page (1.6 MB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.78 g of CO₂e: 213.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

2 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

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

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

Headings skip levels (h1 → h3 and h2 → h4), which makes the page harder to scan with a screen reader.

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

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

The homepage links to 172 pages on semperis.com and 10 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.

Your homepage links to 2 pages by a URL that isn't their canonical one, for example /resources/introducing-ai-agents-to-your-identity-fabric, whose canonical is /resources/white-papers/introducing-ai-agents-to-your-identity-fabric. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/our-customers took over 3 s to send its HTML from our server.

We fetched 15 pages linked from your homepage (of 86 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=187052300&Ver=2&mid=933ab247-a660-4706-9f57-413f9450d04f&bo=1&sid=34019e60d75711f1ab5dbb1d42bb50e6&vid=34019030d75711f191405fc909155249&vids=1&msclkid=N&pi=918639831&l.

5 of 14 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

4 errors were logged to the browser console while the page loaded, for example “Connecting to 'https://go.semperis.com/getCookie?_mchId=239-CPN-851&_mchTd=semperis.com' violates the following Content…”.

Chrome logged issues while loading the page (“Content security policy”).

1 link go through two or more redirects, for example https://semperis.com/services/active-directory-migration-consolidation.

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.

semperis.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.

semperis.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.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage carries about 1,053 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 Ads, Google Analytics, Google Tag Manager, LinkedIn Insight and Microsoft Ads and 2 mores (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 21 cookies (measured from a US location before any click).

Loading the homepage contacts 43 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
