slnt.com website review

About 1.9 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 7.8 s faster on a phone.

20 files are served with short cache lifetimes, so returning visitors download them again (1,011 KiB).

589 KiB JavaScript is shipped twice across bundles. Google estimates it would make the page about 3.0 s faster on a phone.

Your mobile performance score is 46. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.4 s on main-thread work while loading, 2.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, route.com and Klaviyo and others), adding 3.2 MB and 1.6 s of main-thread time.

7 images could be 605 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 450 ms faster on a phone.

Google Tag Manager costs a phone 546 ms of main-thread work and 1.1 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.

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 650 ms.

About 146 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

route.com costs a phone 430 ms of main-thread work and 717 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.

Klaviyo costs a phone 248 ms of main-thread work and 736 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 145 ms of main-thread work and 370 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 1,787 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

19 long tasks block the main thread while loading, the longest for 229 ms. During a long task the page ignores taps.

33 KiB could be saved by minifying CSS.

Polyfills for old browsers add 73 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 100 ms faster on a phone.

5 KiB could be saved by minifying JavaScript.

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

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 25.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 30.8 s. Good is under 3.8 s.

Visually, the page fills in at 10.3 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 691 ms in total while the page loads. Good is under 200 ms.

Real visitors wait 237 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

For real visitors the layout shifts by 0.15 (75th percentile). Good is under 0.1.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 153 ms to 196 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

The first text or image appears after 2.4 s on a phone. Good is under 1.8 s.

3 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 1.9 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.7 MB in 320 requests on a phone: scripts 3.5 MB (125), other files 1.1 MB (163) and images 719 KiB (8). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.63 g of CO₂e: 195.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

8 elements use ARIA attributes their role does not allow, which confuses screen readers.

Summary elements must have discernible text: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 65 elements on the page fail this check, rated moderate by axe-core.

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

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

19 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.

Headings skip levels (h2 → h6), which makes the page harder to scan with a screen reader.

Your title is only 18 characters: “SLNT® Faraday Bags”. Between 30 and 65 characters leaves room to say what you do and for whom.

2 links have no real href, so search engines can't follow them.

The homepage links to 139 pages on slnt.com and 2 external pages.

Your robots.txt lets ChatGPT search (OAI-SearchBot), ChatGPT (ChatGPT-User), Claude search (Claude-SearchBot), Claude (Claude-User), Perplexity (PerplexityBot) and Perplexity (Perplexity-User) read the homepage but closes other sections to them, so answers about those pages can't cite you.

/blogs/insights/tagged/journal and /blogs/insights/tagged/how-to are marked noindex but linked from your homepage. If they are meant to be found, remove the noindex.

/blogs/privacy-trends, /pages/corporate-and-custom-printing and /policies/shipping-policy have no meta description, so Google writes the search snippet from whatever text it finds.

/blogs/insights, /blogs/insights/tagged/journal and /blogs/insights/tagged/how-to use the same meta description. A description written for each page earns more clicks.

/pages/about-us, /pages/le-military, /pages/wholesale, /pages/corporate-and-custom-printing and /pages/collab-with-us have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 58 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://cdn.klaviyomail.com/company/JxwMTe/images/e4d8cd17-8b8c-4f20-8ac2-d80870ab94da.png.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

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

1 image is 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.

2 links go through two or more redirects, for example https://slnt.com/account.

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.

slnt.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.

slnt.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.

Social proof on the homepage: 1 testimonial or review block. 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 279 words of visible text.

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

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 Ads, Google Analytics, Google Tag Manager, Klaviyo 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 13 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 53 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
