vitacost.com website review

The page has 6,027 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 5.5 s on main-thread work while loading, 2.4 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Shopify and Monetate and others), adding 12.7 MB and 961 ms of main-thread time.

70 images could be 1.1 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 500 ms faster on a phone.

Shopify costs a phone 246 ms of main-thread work and 11.3 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.

Your mobile performance score is 67. Pages that score under 90 lose visitors before the first paint.

20 files are served with short cache lifetimes, so returning visitors download them again (538 KiB).

About 464 KiB of JavaScript is downloaded but never used on this page.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

About 63 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.

Google Tag Manager costs a phone 301 ms of main-thread work and 469 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.

Attentive costs a phone 84 ms of main-thread work and 639 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.

10 long tasks block the main thread while loading, the longest for 205 ms. During a long task the page ignores taps.

27 KiB JavaScript is shipped twice across bundles.

Polyfills for old browsers add 10 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.

3 KiB could be saved by minifying CSS.

The page becomes fully interactive after 20.2 s. Good is under 3.8 s.

Your largest element takes 5.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “20% off probiotics. Shop Now. Code: OCT26DAILY”.

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

Scripts block taps and scrolling for 235 ms in total while the page loads. Good is under 200 ms.

Your homepage downloads 15.5 MB in 381 requests on a phone: images 12.7 MB (130), scripts 1.4 MB (98) and other files 909 KiB (106). Under 2 MB keeps phones on slow connections fast.

VITACOST_FreeShipping_2026_960x960_v2_30.jpg 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 4.38 g of CO₂e: 525.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

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

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

Alternative text of images should not be repeated as text: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.

Your <h1> is empty.

The homepage links to 489 pages on vitacost.com and 4 external pages.

There is no /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.

We fetched 15 pages linked from your homepage (of 197 found) and read each the way a search engine does.

69 of 279 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

4 errors were logged to the browser console while the page loaded, for example “Boost > [ERROR] Failed to load customized script Error: Failed to load asset customizedScript”.

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: 96 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.

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 1,173 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Pinterest Tag (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 24 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 27 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
