viscosoft.com website review

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

8 third-party services load with your homepage (twiliocdn.com, alia-prod.com and Shopify and others), adding 2.3 MB and 1.0 s of main-thread time.

52 files are served with short cache lifetimes, so returning visitors download them again (1.1 MB).

Your mobile performance score is 61. Pages that score under 90 lose visitors before the first paint.

21 images could be 397 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 656 KiB of JavaScript is downloaded but never used on this page.

6 long tasks block the main thread while loading, the longest for 503 ms. During a long task the page ignores taps.

twiliocdn.com costs a phone 380 ms of main-thread work and 677 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.

About 135 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.

A phone's processor spends 3.6 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

alia-prod.com costs a phone 305 ms of main-thread work and 377 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.

The page has 1,768 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

videowise.com costs a phone 47 ms of main-thread work and 695 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.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

Polyfills for old browsers add 65 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.

5 KiB could be saved by minifying CSS.

The page becomes fully interactive after 22.3 s. Good is under 3.8 s.

Visually, the page fills in at 10.2 s (Speed Index). Good is under 3.4 s.

Your largest element takes 5.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Designed by topper experts. Comfort that adapts. A mattress…”.

Scripts block taps and scrolling for 366 ms in total while the page loads. Good is under 200 ms.

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

Your homepage downloads 5.3 MB in 259 requests on a phone: scripts 1.8 MB (85), other files 1.4 MB (107) and images 1.1 MB (37). Under 2 MB keeps phones on slow connections fast.

2 images are downloaded at several times the size a phone draws them, for example hp-hero-10.5.2026-mobile2.jpg at 1,500 px wide, shown at 390 px. Resized copies would save about 110 KiB.

2 images further down the page (117 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 1.50 g of CO₂e: 179.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 tap target is too small or too close together to hit reliably with a finger.

All page content should be contained by landmarks: 4 elements on the page fail this check, rated moderate by axe-core.

Alternative text of images should not be repeated as text: 11 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.

Your title is 68 characters, so Google will cut it off around 60: “Top-Rated Memory Foam Mattress Toppers, Pads and Pillows | ViscoSoft”.

Your meta description is 313 characters; Google truncates after about 160, so the end of your pitch is cut.

Your <h1> is empty.

The homepage links to 135 pages on viscosoft.com and 13 external pages.

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.

We fetched 15 pages linked from your homepage (of 65 found) and read each the way a search engine does.

8 of 28 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Uncaught TypeError: Failed to construct 'URL': Invalid URL”.

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.

viscosoft.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.

viscosoft.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.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

The homepage carries about 1,328 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 Klaviyo (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 9 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 26 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
