sdvi.com website review

22 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.1 s.

About 294 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.6 s faster on a phone.

Your mobile performance score is 49 (desktop: 93). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

About 163 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 920 ms faster on a phone.

9 files are served with short cache lifetimes, so returning visitors download them again (105 KiB).

8 third-party services load with your homepage (Google Tag Manager, Hubspot and LinkedIn Ads and others), adding 742 KiB and 595 ms of main-thread time.

Google Tag Manager costs a phone 496 ms of main-thread work and 494 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.

4 images could be 370 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

10 long tasks block the main thread while loading, the longest for 304 ms. During a long task the page ignores taps.

A phone's processor spends 2.4 s on main-thread work while loading, 946 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 1,517 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Polyfills for old browsers add 13 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

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

Desktop scores 93 but mobile only 49. 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.

Your largest element takes 14.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Media Supply Chain Transformation is Your Competitive Advan…”.

The page becomes fully interactive after 14.7 s. Good is under 3.8 s.

The first text or image appears after 4.1 s on a phone. Good is under 1.8 s.

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

Scripts block taps and scrolling for 455 ms in total while the page loads. Good is under 200 ms.

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

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 2.2 MB in 90 requests on a phone: scripts 865 KiB (31), images 719 KiB (18) and stylesheets 224 KiB (21). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.61 g of CO₂e: 73.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

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

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

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

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

4 links have no real href, so search engines can't follow them.

The homepage links to 77 pages on sdvi.com and 9 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

There is no https://sdvi.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.

We fetched 15 pages linked from your homepage (of 31 found) and read each the way a search engine does.

3 of 7 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

6 errors were logged to the browser console while the page loaded, for example “Refused to apply style from 'https://sdvi.com/wp-content/plugins/js_composer/assets/css/lib/typicons/src/font/typicons.…”.

Chrome logged issues while loading the page (“Content security policy”).

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 395 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, HubSpot and LinkedIn Insight (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 3 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 18 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
