inergytek.com website review

About 1.7 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 11.9 s faster on a phone.

24 files are served with short cache lifetimes, so returning visitors download them again (572 KiB).

8 third-party services load with your homepage (YouTube, Google Tag Manager and Clarity and others), adding 3.5 MB and 1.3 s of main-thread time.

Your mobile performance score is 51. Pages that score under 90 lose visitors before the first paint.

YouTube costs a phone 656 ms of main-thread work and 2.2 MB 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.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 750 ms.

Google Tag Manager costs a phone 363 ms of main-thread work and 731 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 92 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

Polyfills for old browsers add 65 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.

3 images could be 58 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.

A phone's processor spends 3.4 s on main-thread work while loading, 1.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

emotivecdn.io costs a phone 94 ms of main-thread work and 384 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.

11 long tasks block the main thread while loading, the longest for 166 ms. During a long task the page ignores taps.

31 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.

The first text or image appears after 15.6 s on a phone. Good is under 1.8 s.

Your largest element takes 28.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Visually, the page fills in at 15.6 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 31.2 s. Good is under 3.8 s.

Scripts block taps and scrolling for 225 ms in total while the page loads. Good is under 200 ms.

2 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 112 ms to 119 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 5.1 MB in 279 requests on a phone: scripts 3.5 MB (96), other files 812 KiB (141) and HTML 229 KiB (8). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.44 g of CO₂e: 172.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

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

All page content should be contained by landmarks: 10 elements on the page fail this check, rated moderate by axe-core.

Document should not have more than one banner landmark: 1 element on the page fails this check, rated moderate by axe-core.

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

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.

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

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

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

Structured data found (Organization and WebSite) but with 1 problem, for example “WebSite: potentialAction.target is not an absolute URL ("https://inergytek.com/search?q={search_term_string}")”.

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

2 links have no real href, so search engines can't follow them.

The homepage links to 38 pages on inergytek.com and 16 external pages.

https://inergytek.com/products/flexp3, https://inergytek.com/pages/support, https://inergytek.com/blogs/power-for-life, https://inergytek.com/policies/shipping-policy, https://inergytek.com/collections/power-stations and https://inergytek.com/pages/contact-us and 1 other have no meta description, so Google writes the search snippet from whatever text it finds.

https://inergytek.com/products/flexp3, https://inergytek.com/collections, https://inergytek.com/collections/power-stations and https://inergytek.com/pages/inergy-patents have no <h1> headline, so visitors and search engines get no clear main topic.

https://inergytek.com/policies/shipping-policy and https://inergytek.com/pages/contact-us 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 19 found) and read each the way a search engine does.

5 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

3 errors were logged to the browser console while the page loaded, for example “Uncaught TypeError: Cannot read properties of null (reading 'innerHTML')”.

Chrome logged issues while loading the page (“Cookie”).

Social proof on the homepage: 1 testimonial or review block. Pairing it with named testimonials or customer logos makes it far more convincing.

The homepage has only about 121 words of visible text; thin pages give Google and first-time buyers little to go on.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 2 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 16 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 42 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
