aptiv.com website review

26 files are served with short cache lifetimes, so returning visitors download them again (457 KiB).

About 304 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.7 s faster on a phone.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

22 images could be 3.4 MB 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.

Your mobile performance score is 64 (desktop: 87). Pages that score under 90 lose visitors before the first paint.

6 third-party services load with your homepage (Google Tag Manager, Optanon and piwik.pro and others), adding 899 KiB and 530 ms of main-thread time.

About 120 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

Google Tag Manager costs a phone 305 ms of main-thread work and 350 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.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 200 ms).

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.

6 long tasks block the main thread while loading, the longest for 123 ms. During a long task the page ignores taps.

19 KiB could be saved by minifying JavaScript.

17 KiB could be saved by minifying CSS.

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 2.1 s for your server to start answering (75th percentile). Good is under 800 ms.

Your largest element takes 9.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “We use cookies to give you the best possible experience whe…”.

The page becomes fully interactive after 9.4 s. Good is under 3.8 s.

Real visitors wait 3.2 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.6 s (75th percentile). Good is under 1.8 s.

Visually, the page fills in at 5.8 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.9 s on a phone. Good is under 1.8 s.

1 image 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 135 ms to 138 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 3.1 s to 3.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 10.6 MB in 77 requests on a phone: images 5.6 MB (29), media 4.0 MB (1) and scripts 718 KiB (22). Under 2 MB keeps phones on slow connections fast.

1 image (34 KiB) is 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 3.02 g of CO₂e: 362.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

12 tap targets are too small or too close together to hit reliably with a finger.

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

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.

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

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

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

Your <h1> is empty.

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

The homepage links to 242 pages on aptiv.com and 23 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.

/ and /en/home all use the title “Aptiv | Home - Global Technology Company”, and 1 other title repeat too. Search engines can't tell which page to show for a search, so each competes with the others.

/en/investors and /en/user/order-history have no meta description, so Google writes the search snippet from whatever text it finds.

/en/contact and /en/contact-us use the same meta description. A description written for each page earns more clicks.

Your homepage links to 9 pages by a URL that isn't their canonical one, for example /en/careers, whose canonical is /en/jobs. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/en/user/order-history and /en/solutions/connection-systems/catalog have no <h1> headline, so visitors and search engines get no clear main topic.

/en/investors 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 113 found) and read each the way a search engine does.

14 of 31 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

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

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

HSTS is set, but max-age is 30 days; one year is the recommended minimum.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

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.

aptiv.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.

aptiv.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.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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 465 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 3 cookies (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.
