sandvine.com website review

34 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.3 s.

Your mobile performance score is 75. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (TrustArc, hsappstatic.net and Hubspot and others), adding 979 KiB and 801 ms of main-thread time.

120 files are served with short cache lifetimes, so returning visitors download them again (467 KiB).

9 images could be 521 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

TrustArc costs a phone 448 ms of main-thread work and 170 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 130 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.

5 long tasks block the main thread while loading, the longest for 322 ms. During a long task the page ignores taps.

A phone's processor spends 2.1 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

hsappstatic.net costs a phone 143 ms of main-thread work and 406 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 1,662 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

About 180 KiB of JavaScript is downloaded but never used on this page.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 13 KiB JavaScript that modern phones do not need.

11 KiB could be saved by minifying CSS.

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.

2 KiB could be saved by minifying JavaScript.

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.

The page becomes fully interactive after 14.6 s. Good is under 3.8 s.

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

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

Real visitors see the first content after 2.4 s (75th percentile). Good is under 1.8 s.

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

The first text or image appears after 2.7 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 383 ms in total while the page loads. Good is under 200 ms.

Your largest element takes 2.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “This site uses cookies and related technologies, as describ…”. Most of its time is element render delay (2.4 s).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 76 ms to 81 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.5 MB in 232 requests on a phone: images 930 KiB (86), scripts 768 KiB (43) and fonts 316 KiB (6). Under 2 MB keeps phones on slow connections fast.

3 images are downloaded at several times the size a phone draws them, for example Maritime Blog Image.jpg at 1,280 px wide, shown at 50 px. Resized copies would save about 198 KiB.

3 images further down the page (199 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 0.70 g of CO₂e: 83.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 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: 23 elements on the page fail this check, rated moderate by axe-core.

Headings should not be empty: 2 elements on the page fail this check, rated minor by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

There are 2 <h1> headlines (“Change your Approach to Observability” and “What's happening at AppLogic Networks”). One clear main headline is easier for people and search engines.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

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

The homepage links to 135 pages on sandvine.com and 26 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://www.applogicnetworks.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 74 found) and read each the way a search engine does.

25 of 31 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

5 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

26 images are served at too low a resolution for sharp phone screens.

Chrome logged issues while loading the page (“Cookie”).

Social proof on the homepage: 6 customer or partner logos. 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.

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 541 words of visible text.

Before a visitor clicks anything, the page loads HubSpot, LinkedIn Insight and Meta Pixel (measured from a US location before any click). A consent tool (TrustArc) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 11 cookies (measured from a US location before any click).

Loading the homepage contacts 27 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
