osmo-official.com website review

About 321 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.3 s faster on a phone.

5 files are served with short cache lifetimes, so returning visitors download them again (213 KiB).

Your mobile performance score is 69. Pages that score under 90 lose visitors before the first paint.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 700 ms.

8 third-party services load with your homepage (Google Tag Manager, Facebook and Klaviyo and others), adding 1.0 MB and 542 ms of main-thread time.

4 images could be 352 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 31 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.

Google Tag Manager costs a phone 242 ms of main-thread work and 306 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.

4 long tasks block the main thread while loading, the longest for 136 ms. During a long task the page ignores taps.

5 KiB could be saved by minifying JavaScript.

3 KiB could be saved by minifying CSS.

About 16 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.

Your largest element takes 9.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 9.1 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 131 ms to 170 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Visually, the page fills in at 4.8 s (Speed Index). Good is under 3.4 s.

1 image 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 1.3 s to 1.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

2 images are downloaded at several times the size a phone draws them, for example 71cTeaOiq7L._AC_SL1500_.jpg at 1,500 px wide, shown at 198 px. Resized copies would save about 279 KiB.

3 images (398 KiB) 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 0.37 g of CO₂e: 44.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Elements must only use permitted ARIA attributes: 7 elements on the page fail this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 24 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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

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

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

The homepage links to 49 pages on osmo-official.com and 0 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.

There is no https://osmo-official.com/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.

robots.txt blocks GPTBot, ClaudeBot, Google-Extended, Applebot-Extended and CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers, which the crawlers above handle.

Your homepage links to 13 pages by a URL that isn't their canonical one, for example https://osmo-official.com/us/about.html, whose canonical is https://osmo-official.com/us/about. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://osmo-official.com/us/collections/home-kitchen.html, https://osmo-official.com/us/collections/health-wellness.html, https://osmo-official.com/us/collections/outdoor-adventure.html, https://osmo-official.com/us/collections/electronics.html, https://osmo-official.com/us/collections/security.html and https://osmo-official.com/us/collections/pet-care.html 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 22 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: the server responded with a status of 409 (Conflict)”.

Social proof on the homepage: a star rating. Pairing it with named testimonials or customer logos makes it far more convincing.

There is no form on the homepage, so every lead has to click through to another page first.

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 325 words of visible text.

Before a visitor clicks anything, the page loads Google Tag Manager, Klaviyo and Meta 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 3 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 13 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
