nerverenew.com website review

About 1.3 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.3 s faster on a phone.

32 files are served with short cache lifetimes, so returning visitors download them again (404 KiB).

Your mobile performance score is 48. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.6 s on main-thread work while loading, 3.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Shopify, Clarity and Google Tag Manager and others), adding 3.3 MB and 1.1 s of main-thread time.

About 169 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 750 ms faster on a phone.

11 images could be 287 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 400 ms faster on a phone.

Shopify costs a phone 256 ms of main-thread work and 1.3 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.

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

rebuyengine.com costs a phone 117 ms of main-thread work and 707 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.

Google CDN costs a phone 123 ms of main-thread work and 299 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.

cloudfront.net costs a phone 87 ms of main-thread work and 387 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.

20 long tasks block the main thread while loading, the longest for 146 ms. During a long task the page ignores taps.

Polyfills for old browsers add 75 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 50 ms faster on a phone.

12 KiB could be saved by minifying CSS.

8 KiB JavaScript is shipped twice across bundles.

6 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.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Your largest element takes 19.4 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 31.7 s. Good is under 3.8 s.

Visually, the page fills in at 9.7 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.6 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 455 ms in total while the page loads. Good is under 200 ms.

8 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 205 ms to 187 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 2.3 s to 2.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 6.0 MB in 520 requests on a phone: scripts 3.0 MB (148), other files 1.5 MB (300) and images 648 KiB (29). Under 2 MB keeps phones on slow connections fast.

1 image is downloaded at several times the size a phone draws it, for example New_Formula_Header_background.png at 3,051 px wide, shown at 390 px. Resized copies would save about 130 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 1.70 g of CO₂e: 204.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must contain particular children: 2 elements on the page fail this check, rated critical by axe-core.

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

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

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.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

1 frame has no title, so screen-reader users cannot tell what it contains.

Your title is only 11 characters: “Nerve Renew”. Between 30 and 65 characters leaves room to say what you do and for whom.

There are 2 <h1> headlines (“” and “Our Strongest Nerve Formula Yet”). One clear main headline is easier for people and search engines.

The homepage links to 26 pages on nerverenew.com and 1 external page.

https://nerverenew.com/pages/manage-subscriptions is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://nerverenew.com/pages/reviews and https://nerverenew.com/pages/claim-page have no meta description, so Google writes the search snippet from whatever text it finds.

https://nerverenew.com/collections/nerve-health, https://nerverenew.com/pages/reviews, https://nerverenew.com/pages/claim-page, https://nerverenew.com/pages/terms-and-conditions and https://nerverenew.com/pages/privacy-policy have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 10 pages linked from your homepage and read each the way a search engine does.

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

6 errors were logged to the browser console while the page loaded, for example “EZ Custom HTML (https://apps.shopify.com/custom-html): Need to subscribe $5/month or $50/year.”.

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

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

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.

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

The homepage carries about 2,089 words of visible text.

Before a visitor clicks anything, the page loads Criteo, Google Ads, Google Analytics, Google Tag Manager and Klaviyo 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 41 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 67 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
