aes.com website review

52 files are served with short cache lifetimes, so returning visitors download them again (346 KiB).

About 214 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 900 ms faster on a phone.

Your mobile performance score is 63 (desktop: 97). Pages that score under 90 lose visitors before the first paint.

12 images could be 780 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

7 third-party services load with your homepage (Google Tag Manager, Optanon and Cloudflare CDN and others), adding 569 KiB and 691 ms of main-thread time.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

Google Tag Manager costs a phone 285 ms of main-thread work and 183 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 2.7 s on main-thread work while loading, 1.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 2,597 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 211 ms. During a long task the page ignores taps.

About 56 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 9 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

Desktop scores 97 but mobile only 63. A gap that wide usually means heavy scripts and images that hit phones hardest.

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 11.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Cookies on this site are used by AES and third party partne…”.

The page becomes fully interactive after 11.1 s. Good is under 3.8 s.

Scripts block taps and scrolling for 369 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 3.6 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 111 ms to 108 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 1.9 s to 1.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.1 MB in 84 requests on a phone: images 2.2 MB (29), scripts 555 KiB (29) and fonts 149 KiB (5). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.87 g of CO₂e: 104.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

Some list items are not inside a list.

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

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

Headings skip levels (h2 → 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).

There is no <h1>, so neither visitors nor Google get a clear main headline.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 221 pages on aes.com and 101 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.

/about-us/careers is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

/investors and /investors/investor-resources all use the title “AES Investors: Resources, Reports, News, Filings & Events”. Search engines can't tell which page to show for a search, so each competes with the others.

/investors and /investors/investor-resources use the same meta description. A description written for each page earns more clicks.

/investors, /investors/events, /investors/presentations-and-webcasts, /investors/reports-filings, /investors/reports-filings/financial-reports and /investors/reports-filings/sec-documents and 5 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 72 found) and read each the way a search engine does.

3 of 8 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 “Failed to load resource: the server responded with a status of 404 ()”.

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.

aes.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.

aes.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.

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.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

Social proof on the homepage: 3 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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

The homepage shows no opening hours. If customers visit or call, show when.

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

Opening the homepage sets 1 cookie (measured from a US location before any click).

Loading the homepage contacts 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
