a313.us website review

About 255 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.6 s faster on a phone.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

Your mobile performance score is 51 (desktop: 77). Pages that score under 90 lose visitors before the first paint.

5 images could be 192 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 750 ms faster on a phone.

8 third-party services load with your homepage (Google Tag Manager, Clarity and Google CDN and others), adding 710 KiB and 696 ms of main-thread time.

About 29 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 600 ms faster on a phone.

Google Tag Manager costs a phone 486 ms of main-thread work and 516 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.

5 long tasks block the main thread while loading, the longest for 259 ms. During a long task the page ignores taps.

A phone's processor spends 2.2 s on main-thread work while loading, 1.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

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

6 files are served with short cache lifetimes, so returning visitors download them again (23 KiB).

Desktop scores 77 but mobile only 51. A gap that wide usually means heavy scripts and images that hit phones hardest.

7 KiB could be saved by minifying JavaScript.

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 13.5 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 13.5 s. Good is under 3.8 s.

The first text or image appears after 4.2 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 6.2 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 428 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.

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 2.1 MB in 169 requests on a phone: scripts 947 KiB (51), other files 672 KiB (94) and images 293 KiB (13). Under 2 MB keeps phones on slow connections fast.

3 images further down the page (92 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.59 g of CO₂e: 70.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

2 tap targets are too small or too close together to hit reliably with a finger.

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

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

2 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 should not be empty: 1 element on the page fails this check, rated minor by axe-core.

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

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

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

Open Graph is missing og:description, so shared links fall back to guesses.

The homepage links to 14 pages on a313.us and 31 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.

/collections/all and /pages/contact have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 5 pages linked from your homepage and read each the way a search engine does.

2 images failed to load on a phone, for example https://bat.bing.com/action/0?ti=149017887&Ver=2&mid=e246a4ce-9b95-4017-a91d-da800a61d94c&bo=1&sid=b2457ff0d2ae11f1ac16598049e0a89b&vid=b24581b0d2ae11f183051f1eddb3ef6d&vids=1&msclkid=N&pi=918639831&l.

3 of 6 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 “Cannot read properties of undefined (reading 'top')”.

1 link to other sites is dead, for example https://twitter.com/frenchpharmafp (404).

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

1 link go through two or more redirects, for example https://a313.us/account/login.

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.

a313.us 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.

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: 14 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

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 964 words of visible text.

a313.us 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 Ads, Google Analytics, Google Tag Manager, Microsoft Ads and Microsoft Clarity (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 27 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
