ocz.com website review

9 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.8 s.

About 209 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.4 s faster on a phone.

Your mobile performance score is 65 (desktop: 93). Pages that score under 90 lose visitors before the first paint.

About 135 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 610 ms faster on a phone.

13 images could be 714 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

8 files are served with short cache lifetimes, so returning visitors download them again (111 KiB).

Polyfills for old browsers add 15 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 200 ms faster on a phone.

4 third-party services load with your homepage (Optanon, dga.jp and Google Fonts and others), adding 324 KiB and 146 ms of main-thread time.

15 KiB could be saved by minifying CSS.

2 long tasks block the main thread while loading, the longest for 65 ms. During a long task the page ignores taps.

Desktop scores 93 but mobile only 65. A gap that wide usually means heavy scripts and images that hit phones hardest.

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 7.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “We use strictly necessary cookies and similar technologies …”.

The page becomes fully interactive after 8.0 s. Good is under 3.8 s.

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

Real visitors see the first content after 2.0 s (75th percentile). Good is under 1.8 s.

Real visitors wait 952 ms for your server to start answering (75th percentile). Good is under 800 ms.

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

The first text or image appears after 3.0 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 5.1 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 92 ms to 95 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 2.5 s to 2.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

12 images (798 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.

10 images further down the page (612 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.41 g of CO₂e: 49.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

1 button has no accessible name, so screen readers announce just “button”.

<dl> elements must only directly contain properly-ordered <dt> and <dd> groups, <script>, <template> or <div> elements: 1 element on the page fails this check, rated serious by axe-core.

3 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: 3 elements on the page fail this check, rated minor by axe-core.

Elements with visible text labels do not have matching accessible names. (1 element).

No meta description, so Google writes its own snippet from whatever text it finds.

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

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

The homepage links to 124 pages on ocz.com and 52 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 https://americas.kioxia.com/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.

https://americas.kioxia.com/pt-br/top.html, https://americas.kioxia.com/es-lar/top.html and https://americas.kioxia.com/en-us/business/memory/selector.html have no meta description, so Google writes the search snippet from whatever text it finds.

https://americas.kioxia.com/en-us/top.html and https://americas.kioxia.com/en-ca/top.html use the same meta description. A description written for each page earns more clicks.

https://americas.kioxia.com/en-us/business/ssd.html and https://americas.kioxia.com/en-us/business/ssd/enterprise-ssd.html took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 52 found) and read each the way a search engine does.

17 of 29 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

2 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://cache.dga.jp/s/tsbmb_api/new_ac.css' from origin 'https://americas.kioxia.com' has…”.

Large scripts ship without source maps.

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 585 words of visible text.

Opening the homepage sets 1 cookie (measured from a US location before any click).

Loading the homepage contacts 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
