decrypt.co website review

About 2.1 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.6 s faster on a phone.

A phone's processor spends 11.5 s on main-thread work while loading, 6.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 29 (desktop: 58). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

The page has 4,323 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Cookiebot, Google Tag Manager and Google/Doubleclick Ads and others), adding 1.6 MB and 1.7 s of main-thread time.

15 files are served with short cache lifetimes, so returning visitors download them again (629 KiB).

20 long tasks block the main thread while loading, the longest for 970 ms. During a long task the page ignores taps.

Cookiebot costs a phone 499 ms of main-thread work and 257 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.

Google Tag Manager costs a phone 406 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.

Google/Doubleclick Ads costs a phone 366 ms of main-thread work and 409 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 373 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 250 ms.

About 40 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

Polyfills for old browsers add 21 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

Desktop scores 58 but mobile only 29. 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.

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.

Your largest element takes 17.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Google. Source: Decrypt/Shutterstock”.

The page becomes fully interactive after 36.0 s. Good is under 3.8 s.

Visually, the page fills in at 13.8 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 3.6 s in total while the page loads. Good is under 200 ms.

The first text or image appears after 3.4 s on a phone. Good is under 1.8 s.

Real visitors wait 242 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 2.3 s to 2.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.7 MB in 234 requests on a phone: scripts 3.8 MB (94), images 638 KiB (26) and fonts 490 KiB (13). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.61 g of CO₂e: 193.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

2 buttons have no accessible name, so screen readers announce just “button”.

Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

ARIA dialog and alertdialog nodes should have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

1 element hidden from screen readers can still receive keyboard focus.

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

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

Alternative text of images should not be repeated as text: 4 elements on the page fail this check, rated minor by axe-core.

Elements with visible text labels do not have matching accessible names. (248 elements).

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

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

The homepage links to 343 pages on decrypt.co and 62 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 /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.

/explainers, /price/bitcoin, /price/ethereum, /price/solana, /price/xrp and /price/hyperliquid and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 199 found) and read each the way a search engine does.

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

2 errors were logged to the browser console while the page loaded, for example “Minified React error #425; visit https://reactjs.org/docs/error-decoder.html?invariant=425 for the full message or use …”.

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

Large scripts ship without source maps.

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.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

Social proof on the homepage: 30 trust badges. 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 2,552 words of visible text.

DMARC is set to p=none, so mail pretending to be decrypt.co is still delivered. Reports are on, so moving to quarantine is the next step.

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 Ads, Google Analytics, Google Tag Manager and X (Twitter) Ads (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 19 cookies, 1 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 41 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
