zandimmunity.com website review

Your mobile performance score is 43. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 5.8 s on main-thread work while loading, 2.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Shopify, Google Tag Manager and Klaviyo and others), adding 1.7 MB and 1.4 s of main-thread time.

About 515 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 380 ms faster on a phone.

Shopify costs a phone 377 ms of main-thread work and 370 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 Tag Manager costs a phone 354 ms of main-thread work and 502 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.

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

Klaviyo costs a phone 211 ms of main-thread work and 321 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 files are served with short cache lifetimes, so returning visitors download them again (106 KiB).

20 long tasks block the main thread while loading, the longest for 170 ms. During a long task the page ignores taps.

5 images could be 87 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

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 9.5 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 17.9 s. Good is under 3.8 s.

Scripts block taps and scrolling for 1.1 s in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 6.5 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 2.5 s on a phone. Good is under 1.8 s.

Your homepage downloads 3.2 MB in 265 requests on a phone: scripts 1.6 MB (108), other files 710 KiB (90) and images 568 KiB (19). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.91 g of CO₂e: 109.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

17 text elements don'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.

All page content should be contained by landmarks: 4 elements on the page fail 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.

1 tap target is too small or too close together to hit reliably with a finger.

Your meta description is 175 characters; Google truncates after about 160, so the end of your pitch is cut.

Your <h1> is empty.

The homepage links to 73 pages on zandimmunity.com and 13 external pages.

There is no https://www.zandimmunity.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.

https://www.zandimmunity.com/collections/immunity, https://www.zandimmunity.com/collections/gummies, https://www.zandimmunity.com/collections/capsules-tablets and https://www.zandimmunity.com/collections/herbals have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 38 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 404 ()”.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

The homepage shows no opening hours. If customers visit or call, show when.

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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

The homepage carries about 504 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, 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 21 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 37 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
