cryptodo.net website review

2 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 (Google Tag Manager, OptiMonk and Shopify and others), adding 8.9 MB and 758 ms of main-thread time.

Your mobile performance score is 58. Pages that score under 90 lose visitors before the first paint.

Shopify costs a phone 85 ms of main-thread work and 8.0 MB 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.

7 images could be 727 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 242 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

30 files are served with short cache lifetimes, so returning visitors download them again (140 KiB).

A phone's processor spends 3.3 s on main-thread work while loading, 1.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Google Tag Manager costs a phone 294 ms of main-thread work and 295 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.

OptiMonk costs a phone 286 ms of main-thread work and 323 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 1,774 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Polyfills for old browsers add 41 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 200 ms faster on a phone.

10 long tasks block the main thread while loading, the longest for 227 ms. During a long task the page ignores taps.

About 56 KiB of CSS is downloaded but never applied on this page.

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

17 KiB JavaScript is shipped twice across bundles.

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 8.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Market Indexes”.

Visually, the page fills in at 10.1 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 12.3 s. Good is under 3.8 s.

Scripts block taps and scrolling for 307 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 2.1 s on a phone. Good is under 1.8 s.

2 images 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 10.1 MB in 289 requests on a phone: media 6.7 MB (3), images 1,009 KiB (51) and other files 962 KiB (154). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 2.88 g of CO₂e: 345.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

28 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 436 elements on the page fail this check, rated moderate by axe-core.

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

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

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

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.

The homepage links to 5 pages on cryptodo.net and 2 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.

We fetched 4 pages linked from your homepage and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

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

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.

cryptodo.net 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.

cryptodo.net'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.

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 411 words of visible text.

cryptodo.net has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

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.

Before a visitor clicks anything, the page loads Google Tag Manager (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 7 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 16 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
