onno.com website review

A phone's processor spends 5.7 s on main-thread work while loading, 2.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Shopify, Facebook and Klaviyo and others), adding 1.3 MB and 930 ms of main-thread time.

9 images could be 1.0 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

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

13 files block the first paint until they finish downloading. Deferring or inlining them could save about 850 ms.

About 395 KiB of JavaScript is downloaded but never used on this page.

Shopify costs a phone 254 ms of main-thread work and 444 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 194 ms of main-thread work and 311 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.

14 long tasks block the main thread while loading, the longest for 249 ms. During a long task the page ignores taps.

12 files are served with short cache lifetimes, so returning visitors download them again (239 KiB).

Polyfills for old browsers add 51 KiB JavaScript that modern phones do not need.

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

About 14 KiB of CSS is downloaded but never applied on this page.

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.

2 KiB could be saved by minifying JavaScript.

The page becomes fully interactive after 18.2 s. Good is under 3.8 s.

Visually, the page fills in at 11.7 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 813 ms in total while the page loads. Good is under 200 ms.

Your largest element takes 4.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Made to Move®”.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 145 ms to 138 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 1.3 s to 1.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 21.3 MB in 380 requests on a phone: media 15.1 MB (2), images 3.2 MB (63) and scripts 1.7 MB (112). Under 2 MB keeps phones on slow connections fast.

8 images are downloaded at several times the size a phone draws them, for example ocW1A-19-A.webp at 1,727 px wide, shown at 268 px. Resized copies would save about 1.1 MB.

ocW1A-19-A.webp weighs 489 KiB. On a phone connection a single image that size takes seconds.

16 images (2.5 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.

By the Sustainable Web Design model, a visit to your homepage emits about 6.05 g of CO₂e: 725.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

ARIA commands must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

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

Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.

The homepage links to 67 pages on onno.com and 2 external pages.

/products/bamboo-t-shirt-women and /products/bamboo-t-shirt-men use the same meta description. A description written for each page earns more clicks.

/products/bamboo-t-shirt-women, /products/long-sleeve-bamboo-t-shirt-women, /products/beechwood-t-shirt-women, /products/hemp-t-shirt-women, /collections/clearance and /products/bamboo-t-shirt-men and 2 others have no <h1> headline, so visitors and search engines get no clear main topic.

/products/bamboo-t-shirt-women, /products/long-sleeve-bamboo-t-shirt-women, /products/beechwood-t-shirt-women, /products/hemp-t-shirt-women, /products/organic-cotton-t-shirt-women and /products/bamboo-t-shirt-men and 1 other have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 15 pages linked from your homepage (of 23 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

Large scripts ship without source maps.

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://onno.com/customer_authentication/redirect?locale=en&region_country=US.

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.

onno.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.

onno.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.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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 285 words of visible text.

DMARC is set to p=none, so mail pretending to be onno.com is still delivered. Add a report address, check the reports, then move to quarantine.

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, Klaviyo, Meta Pixel and TikTok Pixel (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 37 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 36 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
