cdnetworks.com website review

16 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.3 s.

Your mobile performance score is 45. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.5 s on main-thread work while loading, 2.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 272 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 750 ms faster on a phone.

The page goes through 11 redirects before it starts loading, costing about 755 ms. Link and advertise the final URL directly.

Polyfills for old browsers add 51 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 400 ms faster on a phone.

13 long tasks block the main thread while loading, the longest for 447 ms. During a long task the page ignores taps.

About 59 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.

Google Tag Manager costs a phone 261 ms of main-thread work and 197 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 2,444 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

5 third-party services load with your homepage (Google Tag Manager, Hubspot and zi-scripts.com and others), adding 341 KiB and 421 ms of main-thread time.

18 files are served with short cache lifetimes, so returning visitors download them again (213 KiB).

1 image could be 6 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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.

Real visitors see the first content after 3.3 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.9 s for your server to start answering (75th percentile). Good is under 800 ms.

Your largest element takes 8.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “State of WAAP Report 2025 67% of L7 DDoS attacks targeted A…”.

The page becomes fully interactive after 15.7 s. Good is under 3.8 s.

Scripts block taps and scrolling for 1.2 s in total while the page loads. Good is under 200 ms.

Real visitors wait 3.7 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 206 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Visually, the page fills in at 5.8 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 409 ms to 304 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 3.4 s to 3.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.9 MB in 140 requests on a phone: scripts 1.5 MB (48), images 1.2 MB (50) and stylesheets 139 KiB (21). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.83 g of CO₂e: 100.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Documents must have <title> element to aid in navigation: 1 element on the page fails this check, rated serious by axe-core.

<html> element must have a lang attribute: 1 element on the page fails this check, rated serious by axe-core.

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

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

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.

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

Your page has no <title>, so Google has to invent the blue link in search results.

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

There is no <h1>, so neither visitors nor Google get a clear main headline.

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

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

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

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

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

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

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.

No viewport meta tag, so phones render the desktop layout zoomed out.

The page has no <!DOCTYPE html>, so browsers render it in quirks mode.

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

Your certificate from GlobalSign nv-sa · GlobalSign RSA OV SSL CA 2018 expires in 8 days. If it doesn't renew automatically, visitors get a security warning.

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.

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.

cdnetworks.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.

cdnetworks.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.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

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.

The homepage has only about 0 words of visible text; thin pages give Google and first-time buyers little to go on.

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.

DMARC is set to p=none, so mail pretending to be cdnetworks.com is still delivered. Add a report address, check the reports, then move to quarantine.

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 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.
