aviationweek.com website review

About 899 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 5.0 s faster on a phone.

9 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.5 s.

32 files are served with short cache lifetimes, so returning visitors download them again (686 KiB).

Your mobile performance score is 30 (desktop: 43). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.3 s on main-thread work while loading, 4.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Integral Ad Science, Google Tag Manager and Google/Doubleclick Ads and others), adding 2.1 MB and 2.3 s of main-thread time.

7 images could be 278 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 600 ms faster on a phone.

Integral Ad Science costs a phone 480 ms of main-thread work and 211 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 398 ms of main-thread work and 359 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.

About 83 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 340 ms faster on a phone.

Google/Doubleclick Ads costs a phone 330 ms of main-thread work and 480 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.

Accessibe Accessibility Overlay costs a phone 312 ms of main-thread work and 440 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.

transcend-cdn.com costs a phone 328 ms of main-thread work and 188 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.

20 long tasks block the main thread while loading, the longest for 318 ms. During a long task the page ignores taps.

Polyfills for old browsers add 40 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 200 ms faster on a phone.

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.

Real visitors wait 4.7 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 4.7 s (75th percentile). Good is under 1.8 s.

The first text or image appears after 8.2 s on a phone. Good is under 1.8 s.

Your largest element takes 22.3 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 24.4 s. Good is under 3.8 s.

Visually, the page fills in at 11.1 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 1.4 s in total while the page loads. Good is under 200 ms.

Real visitors wait 840 ms for your server to start answering (75th percentile). Good is under 800 ms.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 134 ms to 121 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 4.5 s to 4.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.4 MB in 220 requests on a phone: scripts 2.4 MB (59), images 483 KiB (49) and other files 214 KiB (86). Under 2 MB keeps phones on slow connections fast.

2 images (119 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.

3 images further down the page (93 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.97 g of CO₂e: 116.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

Document should not have more than one contentinfo landmark: 1 element on the page fails this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

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

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

ARIA role should be appropriate for the element: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.

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

Your meta description is 168 characters; Google truncates after about 160, so the end of your pitch is cut.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 287 pages on aviationweek.com and 65 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.

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.

/products, /aerospace, /aerospace/aircraft-propulsion, /aerospace/connected-aerospace, /aerospace/emerging-technologies and /aerospace/manufacturing-supply-chain and 9 others have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example /aerospace/connected-aerospace, whose canonical is /space/connected-aerospace. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/aerospace, /aerospace/aircraft-propulsion, /aerospace/connected-aerospace, /aerospace/emerging-technologies, /aerospace/manufacturing-supply-chain and /aerospace/advanced-air-mobility and 8 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 144 found) and read each the way a search engine does.

7 of 26 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

3 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

5 errors were logged to the browser console while the page loaded, for example “Uncaught TypeError: Cannot assign to read only property 'open' of object '#<Window>'”.

Chrome logged issues while loading the page (“Cookie”).

1 link to other sites is dead, for example https://pgs.aviationweek.com/MROGreaterChina_LearnMore (404).

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

No Content-Security-Policy header, the main browser-side defence against injected scripts.

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.

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

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.

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 1,264 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 Ads, Google Analytics, Google Tag Manager, LinkedIn Insight and Meta Pixel and 2 mores (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 27 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 50 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
