mifo.us website review

About 449 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.2 s faster on a phone.

10 images could be 446 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.4 s faster on a phone.

The page has 5,333 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 65. Pages that score under 90 lose visitors before the first paint.

Shopify costs a phone 255 ms of main-thread work and 728 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.

A phone's processor spends 3.2 s on main-thread work while loading, 905 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

8 third-party services load with your homepage (Shopify, Klaviyo and addons.business and others), adding 989 KiB and 383 ms of main-thread time.

9 files are served with short cache lifetimes, so returning visitors download them again (45 KiB).

4 long tasks block the main thread while loading, the longest for 112 ms. During a long task the page ignores taps.

Polyfills for old browsers add 30 KiB JavaScript that modern phones do not need.

About 11 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.

4 KiB could be saved by minifying CSS.

Your largest element takes 12.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Graphite Mifo Gen 4 earbuds + charging case”.

The page becomes fully interactive after 12.1 s. Good is under 3.8 s.

Visually, the page fills in at 6.7 s (Speed Index). Good is under 3.4 s.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 121 ms to 119 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 1.5 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

mifo-gen4-hires-graphite-system.webp weighs 777 KiB. On a phone connection a single image that size takes seconds.

7 images are downloaded at several times the size a phone draws them, for example mifo-gen4-hires-graphite-system.webp at 1,800 px wide, shown at 297 px. Resized copies would save about 1.1 MB.

Your homepage downloads 3.2 MB in 347 requests on a phone: other files 1.3 MB (227), scripts 970 KiB (75) and images 662 KiB (18). Under 2 MB keeps phones on slow connections fast.

7 images (1.6 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.

mifo-gen4-performance-athlete-v2.webp 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 0.90 g of CO₂e: 107.8 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: 3 elements on the page fail this check, rated serious by axe-core.

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

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

Main landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Document should not have more than one main 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.

Elements with visible text labels do not have matching accessible names. (2 elements).

There are 2 <h1> headlines (“” and “Mifo Gen 4 Wireless Earbuds”). One clear main headline is easier for people and search engines.

The homepage links to 30 pages on mifo.us and 10 external pages.

https://mifo.us/customer_authentication/redirect has no <title>, so Google invents the link text in results.

https://mifo.us/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://mifo.us/customer_authentication/redirect, https://mifo.us/apps/collective/retailer-referral, https://mifo.us/policies/privacy-policy and https://mifo.us/policies/terms-of-service have no meta description, so Google writes the search snippet from whatever text it finds.

https://mifo.us/customer_authentication/redirect and https://mifo.us/apps/collective/retailer-referral have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 18 found) and read each the way a search engine does.

The page uses 1 deprecated browser API that will stop working in future browsers (“Authorization will not be covered by the wildcard symbol (*) in CORS `Access-Control-Allow-Headers`…”).

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 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

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 1,991 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 3 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 17 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 26 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
