vvolt.com website review

A phone's processor spends 7.0 s on main-thread work while loading, 2.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Klaviyo and omnisnippet1.com and others), adding 1.1 MB and 1.5 s of main-thread time.

Your mobile performance score is 56. Pages that score under 90 lose visitors before the first paint.

Google Tag Manager costs a phone 877 ms of main-thread work and 687 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.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 500 ms.

15 images could be 135 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 418 KiB of JavaScript is downloaded but never used on this page.

19 long tasks block the main thread while loading, the longest for 323 ms. During a long task the page ignores taps.

20 files are served with short cache lifetimes, so returning visitors download them again (283 KiB).

The page has 1,607 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

9 KiB JavaScript is shipped twice across bundles. Google estimates it would make the page about 100 ms faster on a phone.

Polyfills for old browsers add 36 KiB JavaScript that modern phones do not need.

23 KiB could be saved by minifying JavaScript.

About 11 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 10 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.

The page becomes fully interactive after 17.7 s. Good is under 3.8 s.

Your largest element takes 5.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Scripts block taps and scrolling for 905 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.4 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Visually, the page fills in at 5.3 s (Speed Index). Good is under 3.4 s.

Your homepage downloads 3.4 MB in 347 requests on a phone: scripts 1.6 MB (118), other files 791 KiB (128) and images 713 KiB (72). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.96 g of CO₂e: 115.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Links must have discernible text: 4 elements on the page fail this check, rated serious by axe-core.

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

Summary elements must have discernible text: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 23 elements on the page fail this check, rated moderate 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, h1 → h5 and h3 → h5), which makes the page harder to scan with a screen reader.

There are 2 <h1> headlines (“” and “Alpha 2.1”). One clear main headline is easier for people and search engines.

Your meta description is 200 characters; Google truncates after about 160, so the end of your pitch is cut.

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

The homepage links to 128 pages on vvolt.com and 4 external pages.

/pages/streek and /pages/dealers have no meta description, so Google writes the search snippet from whatever text it finds.

/collections/alpha-ii-add-ons-and-accessories and /collections/centauri-ii-add-ons-and-accessories use the same meta description. A description written for each page earns more clicks.

/collections/preloved-ebikes, /collections/alpha-ii-add-ons-and-accessories, /collections/centauri-ii-add-ons-and-accessories, /collections/cargo, /collections/accessories and /collections/ebike-jackets and 6 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 38 found) and read each the way a search engine does.

5 errors were logged to the browser console while the page loaded, for example “Uncaught SyntaxError: Unexpected identifier 'site'”.

2 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

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

1 link go through two or more redirects, for example https://vvolt.com/customer_authentication/redirect?locale=en&region_country=US.

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.

vvolt.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.

vvolt.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 customer or partner logo. 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 319 words of visible text.

DMARC is set to p=none, so mail pretending to be vvolt.com is still delivered. Reports are on, so moving to quarantine is the next step.

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, Klaviyo and LinkedIn Insight and 4 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 25 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.
