aventon.com website review

Your mobile performance score is 43 (desktop: 51). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

The page has 7,367 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 5.4 s on main-thread work while loading, 3.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 2.2 MB of JavaScript is downloaded but never used on this page.

8 third-party services load with your homepage (Shopify, Google Tag Manager and Google CDN and others), adding 2.4 MB and 1.1 s of main-thread time.

32 files are served with short cache lifetimes, so returning visitors download them again (662 KiB).

15 images could be 273 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.

About 121 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

17 long tasks block the main thread while loading, the longest for 401 ms. During a long task the page ignores taps.

Shopify costs a phone 327 ms of main-thread work and 576 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 CDN costs a phone 192 ms of main-thread work and 733 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 227 ms of main-thread work and 352 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.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 150 ms.

Polyfills for old browsers add 58 KiB JavaScript that modern phones do not need.

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.

4 KiB could be saved by minifying CSS.

2 KiB could be saved by minifying JavaScript.

The page becomes fully interactive after 39.2 s. Good is under 3.8 s.

Your largest element takes 8.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

Visually, the page fills in at 11.0 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 849 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 2.5 s on a phone. Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' tap response (inp) went from 177 ms to 173 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 3.0 s to 2.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 13.8 MB in 370 requests on a phone: media 5.4 MB (3), scripts 3.8 MB (108) and images 2.6 MB (78). Under 2 MB keeps phones on slow connections fast.

20260313-175252.png weighs 1.5 MB. On a phone connection a single image that size takes seconds.

BrettTippie_ChargersWHT_1024x1024.png is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

2 images (118 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.

By the Sustainable Web Design model, a visit to your homepage emits about 3.90 g of CO₂e: 468.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA attributes must conform to valid names: 1 element on the page fails this check, rated critical by axe-core.

ARIA attributes must conform to valid values: 1 element on the page fails this check, rated critical by axe-core.

22 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 111 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.

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.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

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

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

Alternative text of images should not be repeated as text: 5 elements on the page fail this check, rated minor by axe-core.

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

Headings skip levels (h1 → h3), 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.

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

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

3 links have no real href, so search engines can't follow them.

Open Graph is missing og:title and og:description, so shared links fall back to guesses.

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

The homepage links to 197 pages on aventon.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.

/pages/contact-us, /pages/terms-of-service, /pages/referral-project and /pages/new-releases have no meta description, so Google writes the search snippet from whatever text it finds.

/pages/terms-of-service, /pages/referral-project, /products/current-adv-ebike, /collections/ebikes and /collections/electric-commuter-bike have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 98 found) and read each the way a search engine does.

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

Large scripts ship without source maps.

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

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.

aventon.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: 4 customer or partner logos. 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 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 638 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 Ads, Google Analytics, Google Tag Manager, Hotjar and Pinterest Tag (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 31 cookies (measured from a US location before any click).

Loading the homepage contacts 54 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
