aersf.com website review

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

About 227 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 59 (desktop: 70). Pages that score under 90 lose visitors before the first paint.

About 23 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 620 ms faster on a phone.

17 files are served with short cache lifetimes, so returning visitors download them again (101 KiB).

A phone's processor spends 2.7 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Klaviyo costs a phone 139 ms of main-thread work and 429 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 1,671 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Google Tag Manager, Klaviyo and 9gtb.com and others), adding 923 KiB and 350 ms of main-thread time.

Polyfills for old browsers add 18 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 200 ms faster on a phone.

5 long tasks block the main thread while loading, the longest for 166 ms. During a long task the page ignores taps.

10 KiB could be saved by minifying JavaScript.

2 images could be 85 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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 16.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “TRAVEL KIT 3 TRAVEL KIT 3 Smart toiletries storage that sta…”.

The page becomes fully interactive after 17.1 s. Good is under 3.8 s.

Visually, the page fills in at 7.7 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.2 s on a phone. Good is under 1.8 s.

Real visitors wait 2.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Over the last 25 four-week periods to 2026-10-10, real Chrome visitors' tap response (inp) went from 80 ms to 79 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-10, real Chrome visitors' largest content (lcp) went from 2.5 s to 2.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.2 MB in 316 requests on a phone: other files 1.2 MB (175), scripts 1.1 MB (89) and images 664 KiB (35). Under 2 MB keeps phones on slow connections fast.

1 image further down the page (33 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.92 g of CO₂e: 110.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

Structured data found (WebSite) but with 1 problem, for example “ld+json block 1 is not valid JSON (Expected ',' or ']' after array element in JSON at position )”.

The homepage links to 134 pages on aersf.com and 5 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.

/pages/shipping, /collections/new-arrivals, /collections/best-sellers, /collections/backpacks, /collections/slings and /collections/duffels and 4 others have no meta description, so Google writes the search snippet from whatever text it finds.

/pages/shipping, /collections/new-arrivals and /collections/best-sellers have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 57 found) and read each the way a search engine does.

2 images failed to load on a phone, for example https://bat.bing.com/action/0?ti=56014780&Ver=2&mid=2e5fe0c8-77b4-4428-b1c4-ac7eea3e201e&bo=1&sid=bd306150cb4811f19319e1639996503c&vid=bd308d40cb4811f1b93a6b7d428b3cf7&vids=1&msclkid=N&pi=918639831&lg.

27 of 56 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 “Access to XMLHttpRequest at 'https://crossborder-integration.global-e.com/resources/css/1557/US' from origin 'https://a…”.

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

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.

aersf.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.

aersf.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.

Social proof on the homepage: 1 trust badge. 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 458 words of visible text.

DMARC is set to p=none, so mail pretending to be aersf.com is still delivered. Add a report address, check the reports, then move to quarantine.

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 Tag Manager, Klaviyo and Microsoft Ads (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 9 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 30 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
