volt.io website review

About 281 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.1 s faster on a phone.

Your mobile performance score is 65. Pages that score under 90 lose visitors before the first paint.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

A phone's processor spends 3.0 s on main-thread work while loading, 1.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Google Tag Manager costs a phone 193 ms of main-thread work and 330 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.

6 third-party services load with your homepage (Google Tag Manager, iubenda and New Relic and others), adding 528 KiB and 377 ms of main-thread time.

About 14 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

Polyfills for old browsers add 12 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

5 long tasks block the main thread while loading, the longest for 137 ms. During a long task the page ignores taps.

3 images could be 86 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

4 files are served with short cache lifetimes, so returning visitors download them again (22 KiB).

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 4.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Your largest element takes 11.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “GraphicHomeCheckoutDemo”.

The page becomes fully interactive after 11.3 s. Good is under 3.8 s.

Visually, the page fills in at 7.1 s (Speed Index). Good is under 3.4 s.

For real visitors the layout shifts by 0.15 (75th percentile). Good is under 0.1.

Real visitors see the first content after 2.2 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.4 s for your server to start answering (75th percentile). Good is under 800 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 144 ms to 169 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 3.4 s to 3.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

big.caec11bc.webp 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).

By the Sustainable Web Design model, a visit to your homepage emits about 0.55 g of CO₂e: 66.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Scrollable region must have keyboard access: 2 elements on the page fail this check, rated serious by axe-core.

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

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

The homepage links to 75 pages on volt.io and 8 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.

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

We fetched 15 pages linked from your homepage (of 42 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 402 ()”.

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

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

1 link go through two or more redirects, for example https://www.volt.io/demo/.

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.

volt.io 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.

Social proof on the homepage: 7 testimonial or review blocks. 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.

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 968 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 Analytics and Google Tag Manager (measured from a US location before any click). A consent tool (iubenda) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 5 cookies (measured from a US location before any click).

Loading the homepage contacts 12 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
