atomstack.com website review

A phone's processor spends 23.6 s on main-thread work while loading, 9.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Clarity costs a phone 1.5 s of main-thread work and 30 KiB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

The page has 5,328 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Clarity, reddit and loox.io and others), adding 2.5 MB and 3.3 s of main-thread time.

About 928 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.

Your mobile performance score is 55. Pages that score under 90 lose visitors before the first paint.

About 118 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 830 ms faster on a phone.

reddit costs a phone 810 ms of main-thread work and 32 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.

loox.io costs a phone 427 ms of main-thread work and 624 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.

Shopify costs a phone 318 ms of main-thread work and 880 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.

28 files are served with short cache lifetimes, so returning visitors download them again (301 KiB).

azurefd.net costs a phone 55 ms of main-thread work and 321 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.

13 long tasks block the main thread while loading, the longest for 230 ms. During a long task the page ignores taps.

Polyfills for old browsers add 29 KiB JavaScript that modern phones do not need.

2 images could be 24 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

11 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.

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 26.9 s. Good is under 3.8 s.

Visually, the page fills in at 15.0 s (Speed Index). Good is under 3.4 s.

Your largest element takes 6.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Halloween Sale: Buy More,Save More.”.

Real visitors wait 272 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 217 ms to 307 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors wait 1.1 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 495 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.1 s to 2.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.4 MB in 597 requests on a phone: scripts 2.3 MB (197), other files 1.5 MB (306) and images 787 KiB (63). Under 2 MB keeps phones on slow connections fast.

AtomStack_SWIFT-banner750x1080_1.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 1.53 g of CO₂e: 183.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Scrollable region must have keyboard access: 2 elements on the page fail this check, rated serious by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 4 elements on the page fail this check, rated moderate by axe-core.

Contentinfo landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Document should not have more than one contentinfo landmark: 1 element on the page fails this check, rated moderate by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

20 visible links have no text or label, so screen readers cannot say where they go.

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

ARIA role should be appropriate for the element: 3 elements on the page fail this check, rated minor by axe-core.

Alternative text of images should not be repeated as text: 3 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h1 → h3, h2 → h4 and h2 → h4), which makes the page harder to scan with a screen reader.

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

Your meta description is 258 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 567 pages on atomstack.com and 8 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.

/pages/halloween-sale has no meta description, so Google writes the search snippet from whatever text it finds.

/products/atomstack-p1, /pages/halloween-sale, /collections/a-series, /products/atomstack-a70-max, /products/atomstack-ace-a40-pro-v2-laser-engraver and /products/atomstack-ace-pro-v2 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 159 found) and read each the way a search engine does.

10 of 45 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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

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.

atomstack.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.

atomstack.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.

Social proof on the homepage: 4 testimonial or review blocks. 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.

The homepage carries about 1,158 words of visible text.

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, Meta Pixel and Microsoft Ads and 2 mores (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 30 cookies, 2 of them by other companies (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 50 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
