immersion.com website review

55 files are served with short cache lifetimes, so returning visitors download them again (5.1 MB).

27 files block the first paint until they finish downloading. Deferring or inlining them could save about 4.9 s.

About 266 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.4 s faster on a phone.

9 images could be 1.2 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 400 ms faster on a phone.

Your mobile performance score is 57 (desktop: 84). Pages that score under 90 lose visitors before the first paint.

About 152 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 600 ms faster on a phone.

40 KiB could be saved by minifying CSS.

5 third-party services load with your homepage (Cloudflare CDN, Bootstrap CDN and Google Fonts and others), adding 211 KiB and 33 ms of main-thread time.

The HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.

29 KiB JavaScript is shipped twice across bundles.

21 KiB could be saved by minifying JavaScript.

Desktop scores 84 but mobile only 57. 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.

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

Real visitors see the first content after 4.1 s (75th percentile). Good is under 1.8 s.

Real visitors wait 2.3 s for your server to start answering (75th percentile). Good is under 800 ms.

The first text or image appears after 5.5 s on a phone. Good is under 1.8 s.

Your largest element takes 6.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image. Most of its time is resource load duration (3.5 s).

Visually, the page fills in at 8.4 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 6.7 s. Good is under 3.8 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 2026-10-17, real Chrome visitors' largest content (lcp) went from 4.2 s to 4.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.5 MB in 75 requests on a phone: images 3.1 MB (27), media 1.5 MB (1) and scripts 406 KiB (21). Under 2 MB keeps phones on slow connections fast.

3 images (431 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.

1 image further down the page (28 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 1.55 g of CO₂e: 186.0 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: 9 elements on the page fail this check, rated moderate by axe-core.

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

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

No Open Graph image (also missing: og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 49 pages on immersion.com and 0 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 /latest-news, which answers with an error. Visitors hit a dead end and search engines drop it.

/gaming is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

/automotive, /gaming, /mobile, /technology, /haptics-resource-library and /partners and 8 others use the same meta description. A description written for each page earns more clicks.

Your homepage links to 2 pages by a URL that isn't their canonical one, for example /mobile, whose canonical is /ja/mobile. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/automotive, /gaming, /mobile, /technology, /partners and /about and 1 other have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 19 found) and read each the way a search engine does.

5 of 8 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

3 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 403 ()”.

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

No Content-Security-Policy header, the main browser-side defence against injected scripts.

The server only offers HTTP/1.1, so browsers open several connections and load files more slowly. Most hosts and CDNs turn on HTTP/2 with a setting.

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

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

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.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

immersion.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.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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 355 words of visible text.

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

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.

Opening the homepage sets 4 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 6 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
