cloudsecurityalliance.org website review

42 files are served with short cache lifetimes, so returning visitors download them again (2.3 MB).

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 4.7 s.

About 1,018 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 39. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.2 s on main-thread work while loading, 2.4 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google CDN, Google Tag Manager and ZenDesk and others), adding 2.1 MB and 1.4 s of main-thread time.

10 images could be 1.4 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 138 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 750 ms faster on a phone.

Google CDN costs a phone 662 ms of main-thread work and 1.1 MB 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.

85 KiB could be saved by minifying CSS.

Google Tag Manager costs a phone 382 ms of main-thread work and 374 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.

ZenDesk costs a phone 257 ms of main-thread work and 392 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.

18 long tasks block the main thread while loading, the longest for 252 ms. During a long task the page ignores taps.

The page has 1,525 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

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

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 10.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Join CSA. Get Frontier Ready. Prepare for machine-speed cyb…”.

The page becomes fully interactive after 24.7 s. Good is under 3.8 s.

The first text or image appears after 5.3 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 978 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 6.0 s (Speed Index). Good is under 3.4 s.

Real visitors wait 3.5 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 3.4 s to 4.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.7 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.5 s for your server to start answering (75th percentile). Good is under 800 ms.

35 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' tap response (inp) went from 213 ms to 218 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 7.2 MB in 84 requests on a phone: images 3.8 MB (35), scripts 2.5 MB (15) and other files 375 KiB (17). Under 2 MB keeps phones on slow connections fast.

3 images (669 KiB) 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 2.04 g of CO₂e: 244.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

12 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.

2 links inside paragraphs rely on colour alone to stand out.

<html> element must have a lang attribute: 1 element on the page fails this check, rated serious by axe-core.

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

37 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.

The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.

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

Your title is only 10 characters: “Home | CSA”. Between 30 and 65 characters leaves room to say what you do and for whom.

There are 3 <h1> headlines (“Join CSA. Get Frontier Ready.”, “Trusted AI Safety Expert (TAISE) Certificate” and “Build Trustworthy AI with CSA's AI Controls Matrix”). One clear main headline is easier for people and search engines.

Structured data found (Organization) but with 1 problem, for example “Organization: missing @context (expected "https://schema.org")”.

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

The homepage links to 229 pages on cloudsecurityalliance.org and 31 external pages.

Your Organization JSON-LD is missing logo, 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.

/blog has no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 85 found) and read each the way a search engine does.

2 links go through two or more redirects, for example https://www.csacloudbytes.com/.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

Social proof on the homepage: 4 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

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 1,216 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 and Microsoft Clarity (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 2 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 18 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
