byterry.com website review

12 images could be 1.7 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.3 s faster on a phone.

About 281 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.

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

A phone's processor spends 6.6 s on main-thread work while loading, 3.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 3,593 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 57. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Bazaarvoice, Clarity and Google Tag Manager and others), adding 980 KiB and 657 ms of main-thread time.

About 78 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.

14 files are served with short cache lifetimes, so returning visitors download them again (86 KiB).

5 long tasks block the main thread while loading, the longest for 254 ms. During a long task the page ignores taps.

Shopify costs a phone 109 ms of main-thread work and 397 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.

Polyfills for old browsers add 26 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 100 ms faster on a phone.

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.

3 KiB could be saved by minifying CSS.

3 KiB could be saved by minifying JavaScript.

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 18.9 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 19.4 s. Good is under 3.8 s.

Visually, the page fills in at 11.2 s (Speed Index). Good is under 3.4 s.

Real visitors wait 3.0 s for the largest content to appear (75th percentile). Good is under 2.5 s.

The first text or image appears after 2.6 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 243 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 150 ms to 179 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.2 s to 2.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 6.4 MB in 397 requests on a phone: images 3.6 MB (46), other files 1.3 MB (256) and scripts 1.1 MB (77). Under 2 MB keeps phones on slow connections fast.

download_28.gif weighs 1.5 MB. On a phone connection a single image that size takes seconds.

7 images (2.4 MB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

1663x2518_uk.gif 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 1.80 g of CO₂e: 216.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

All page content should be contained by landmarks: 3 elements on the page fail this check, rated moderate by axe-core.

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

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

Elements with visible text labels do not have matching accessible names. (1 element).

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

There are 2 <h1> headlines (“BY TERRY” and “BY TERRY”). One clear main headline is easier for people and search engines.

Your meta description is 199 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 245 pages on byterry.com and 6 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.

We fetched 15 pages linked from your homepage (of 71 found) and read each the way a search engine does.

The page uses 1 deprecated browser API that will stop working in future browsers (“CSS appearance value `slider-vertical` is not standardized and will be removed.”).

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.

byterry.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: 1 trust badge. 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 348 words of visible text.

DMARC is set to p=none, so mail pretending to be byterry.com 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 Tag Manager, Klaviyo 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 14 cookies, 1 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 23 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
