aero.com website review

A phone's processor spends 10.5 s on main-thread work while loading, 7.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Stripe, Google Tag Manager and Facebook and others), adding 1.4 MB and 1.9 s of main-thread time.

20 long tasks block the main thread while loading, the longest for 1.7 s. During a long task the page ignores taps.

Your mobile performance score is 63. Pages that score under 90 lose visitors before the first paint.

27 files are served with short cache lifetimes, so returning visitors download them again (961 KiB).

About 877 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 60 ms faster on a phone.

Google Tag Manager costs a phone 544 ms of main-thread work and 531 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.

Stripe costs a phone 547 ms of main-thread work and 281 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.

Facebook costs a phone 297 ms of main-thread work and 228 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 1,587 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

1 image could be 13 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

Polyfills for old browsers add 51 KiB JavaScript that modern phones do not need.

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

34 KiB could be saved by minifying JavaScript.

About 28 KiB of CSS is downloaded but never applied on this page.

10 KiB JavaScript is shipped twice across bundles.

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.

Scripts block taps and scrolling for 5.3 s in total while the page loads. Good is under 200 ms.

The page becomes fully interactive after 23.6 s. Good is under 3.8 s.

Real visitors wait 362 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

For real visitors the layout shifts by 0.11 (75th percentile). Good is under 0.1.

Real visitors wait 1.1 s for your server to start answering (75th percentile). Good is under 800 ms.

Visually, the page fills in at 5.0 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 330 ms to 350 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.8 s to 1.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.2 MB in 127 requests on a phone: scripts 2.8 MB (44), other files 144 KiB (65) and fonts 136 KiB (4). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.92 g of CO₂e: 110.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

Scrollable region must have keyboard access: 2 elements on the page fail this check, rated serious by axe-core.

All page content should be contained by landmarks: 47 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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

Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

Elements with visible text labels do not have matching accessible names. (12 elements).

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

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

The homepage links to 55 pages on aero.com and 8 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

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.

/flights has under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 15 pages linked from your homepage (of 22 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 401 ()”.

Large scripts ship without source maps.

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

3 links go through two or more redirects, for example https://aero.com/api/auth/login?screen=login.

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.

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

aero.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.

aero.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.

There is no form on the homepage, so every lead has to click through to another page first.

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 737 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 Segment (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 5 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 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
