microair.net website review

About 505 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.5 s faster on a phone.

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.0 s.

19 images could be 442 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 800 ms faster on a phone.

Your mobile performance score is 56. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, Shopify and Clarity and others), adding 1.1 MB and 579 ms of main-thread time.

10 files are served with short cache lifetimes, so returning visitors download them again (95 KiB).

A phone's processor spends 2.9 s on main-thread work while loading, 1.4 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Google Tag Manager costs a phone 192 ms of main-thread work and 354 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.

Shopify costs a phone 136 ms of main-thread work and 503 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.

About 45 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

7 long tasks block the main thread while loading, the longest for 138 ms. During a long task the page ignores taps.

38 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.

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.

For real visitors the layout shifts by 0.45 (75th percentile). Good is under 0.1.

Your largest element takes 16.1 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 16.1 s. Good is under 3.8 s.

The first text or image appears after 4.5 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 7.5 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 92 ms to 105 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 1.6 s to 1.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.3 MB in 233 requests on a phone: scripts 1.3 MB (54), images 1.0 MB (48) and other files 714 KiB (102). Under 2 MB keeps phones on slow connections fast.

2 images further down the page (52 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 0.94 g of CO₂e: 113.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 link inside paragraphs relies on colour alone to stand out.

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

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

3 form fields have no label, so screen readers announce an empty box and autofill guesses.

Headings should not be empty: 2 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h2 → h6, h2 → h6 and h2 → h6), which makes the page harder to scan with a screen reader.

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your title is 85 characters, so Google will cut it off around 60: “Leaders in Custom Marine & RV A/C Controls, Soft Starters & Displays – Micro-Air, LLC”.

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

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

8 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

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

The homepage links to 117 pages on microair.net and 22 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.

We fetched 15 pages linked from your homepage (of 39 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=247009111&Ver=2&mid=597256ce-9ec4-4102-a79b-63a88ca8edad&bo=1&sid=c9ed5330da6c11f1bd9d1b1d0cb98e0d&vid=c9ed70d0da6c11f1ac552fc03e1de4e5&vids=1&msclkid=N&pi=918639831&l.

2 errors were logged to the browser console while the page loaded, for example “Shopify's Google Analytics stub called with: [array Array] See https://help.shopify.com/manual/promoting-marketing/pixe…”.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

Social proof on the homepage: 51 testimonial or review blocks. 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.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 847 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, LinkedIn Insight 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 28 cookies, 4 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 35 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
