Speed

9 to fix59

  • Reduce unused JavaScript

    2.1 s · 755 KiB

    About 755 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.1 s faster on a phone.

  • 5,402 HTML elements

    The page has 5,402 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

  • Main-thread work: 4.0 s

    A phone's processor spends 4.0 s on main-thread work while loading, 2.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • 8 third-party services on the page

    8 third-party services load with your homepage (Google Tag Manager, Shopify and heatmap.com and others), adding 2.3 MB and 793 ms of main-thread time.

  • Mobile performance score: 59

    59/100

    Your mobile performance score is 59. Pages that score under 90 lose visitors before the first paint.

  • Google Tag Manager adds 599 ms

    599 ms

    Google Tag Manager costs a phone 599 ms of main-thread work and 1.2 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.

  • Reduce unused CSS

    300 ms · 43 KiB

    About 43 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.

  • Render-blocking requests

    300 ms

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

  • Shopify adds 135 ms

    135 ms

    Shopify costs a phone 135 ms of main-thread work and 885 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.

  • 12 long tasks on the main thread

    12 long tasks block the main thread while loading, the longest for 111 ms. During a long task the page ignores taps.

  • Use efficient cache lifetimes

    57 KiB

    13 files are served with short cache lifetimes, so returning visitors download them again (57 KiB).

  • Font display

    50 ms

    Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

  • Improve image delivery

    26 KiB

    1 image could be 26 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • Chained critical requests

    Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

1 checks passed

  • Server response: 17 ms

    17 ms

    Your server sent the HTML in 17 ms, well inside Google's 600 ms guideline.

Core Web Vitals

8 to fix100

  • Fails Core Web Vitals for real visitors

    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.

  • Largest Contentful Paint: 12.4 s

    12.4 s

    Your largest element takes 12.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Image without description”.

Images and page weight

1 to fix85

  • Page weight: 3.9 MB in 392 requests

    3.9 MB

    Your homepage downloads 3.9 MB in 392 requests on a phone: scripts 2.1 MB (187), other files 928 KiB (143) and images 353 KiB (29). Under 2 MB keeps phones on slow connections fast.

  • About 1.1 g of CO₂ per visit

    1.11 g

    By the Sustainable Web Design model, a visit to your homepage emits about 1.11 g of CO₂e: 133.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 checks passed

  • Images use modern formats

    Every sizeable image is WebP, AVIF or SVG.

  • Images load when needed

    Images below the first screen wait until the visitor scrolls to them.

  • Images are sized for phones

    No image is downloaded at more than three times the size it is drawn on a phone.

Accessibility

5 to fixGoogle 10093

  • 294 images without alt text

    294 images have no alt text, which hurts accessibility and image search.

  • Scrollable region must have keyboard access (2 elements)

    Scrollable region must have keyboard access: 2 elements on the page fail this check, rated serious by axe-core.

  • Document should not have more than one banner landmark (1 element)

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

  • Landmarks should have a unique role or role/label/title (i.e. accessible name) combination (1 element)

    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.

  • All page content should be contained by landmarks (1 element)

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

  • Headings skip levels

    Headings skip levels (h1 → h3 and h3 → h5), which makes the page harder to scan with a screen reader.

1 checks passed

  • 42 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 46 WCAG 2.2 A/AA and best-practice rules on the phone render: 42 passed and 4 failed. 4 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

1 to fixGoogle 10095

  • 9 H1 headlines

    There are 9 <h1> headlines (“Biotic⁺”, “Magnesium⁺” and “Vitals⁺”). One clear main headline is easier for people and search engines.

  • 64 internal links, 16 external

    The homepage links to 64 pages on yourheights.com and 16 external pages.

7 checks passed

  • Meta description: 152 characters

    Your meta description is 152 characters: “Feel clearer, think sharper, and improve your energy with Heights. Our science-backed supplements support your brain an…”.

  • Title: 59 characters

    Your title is a healthy 59 characters: “Heights - Science-Backed Supplements For Your Brain and Gut”.

  • Canonical URL set

    The canonical URL is https://www.heights.com/.

  • Structured data in place

    Structured data found: Organization and WebPage.

  • Open Graph tags complete

    Open Graph tags are complete, so shared links show a title, description and image.

  • robots.txt in place

    robots.txt is in place and points crawlers to your sitemap.

  • XML sitemap found

    Your XML sitemap is reachable at https://www.heights.com/sitemap.xml.

AI search readiness

1 to fix83

  • Parts of the site are closed to 6 AI crawlers

    Your robots.txt lets ChatGPT search (OAI-SearchBot), ChatGPT (ChatGPT-User), Claude search (Claude-SearchBot), Claude (Claude-User), Perplexity (PerplexityBot) and Perplexity (Perplexity-User) read the homepage but closes other sections to them, so answers about those pages can't cite you.

3 checks passed

  • Organization data: 5 of 6 facts

    Your Organization JSON-LD gives name, url, logo, sameAs (social profiles) and contact details; description would complete it.

  • Text is in the HTML

    Your server sends the page's text in the HTML (5,487 words), so crawlers that don't run JavaScript still read it.

  • llms.txt published

    The site publishes https://www.heights.com/llms.txt (6 KiB, 8 links), a plain-text guide to the site for AI tools.

Other pages

3 to fix83

  • 2 pages share a title

    https://www.heights.com/collections/supplements-2 and https://www.heights.com/collections/supplements all use the title “Supplements - Heights”. Search engines can't tell which page to show for a search, so each competes with the others.

  • 9 pages without a meta description

    https://www.heights.com/collections/best-sellers, https://www.heights.com/pages/bundle-builder, https://www.heights.com/collections/supplements-2, https://www.heights.com/collections/bundles, https://www.heights.com/pages/science and https://www.heights.com/pages/ingredients and 3 others have no meta description, so Google writes the search snippet from whatever text it finds.

  • 1 page without an H1

    https://www.heights.com/collections/shop-all has no <h1> headline, so visitors and search engines get no clear main topic.

  • 14 pages with very little text

    https://www.heights.com/collections/best-sellers, https://www.heights.com/pages/bundle-builder, https://www.heights.com/collections/supplements-2, https://www.heights.com/collections/bundles, https://www.heights.com/products/vitals and https://www.heights.com/products/biotic and 8 others 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.

  • 4 pages slow to respond

    https://www.heights.com/collections/best-sellers, https://www.heights.com/pages/bundle-builder, https://www.heights.com/collections/supplements-2 and https://www.heights.com/collections/bundles took over 3 s to send their HTML from our server.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 25 found) and read each the way a search engine does.

4 checks passed

  • Linked pages load

    All 15 pages we checked loaded without an error.

  • Every page has a title

    All 15 pages that loaded have a <title>.

  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

1 to fix93

  • No direct contact details

    No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

  • About 398 words of copy

    The homepage carries about 398 words of visible text.

6 checks passed

  • Clear next step on the first screen

    On a phone, the first screen shows a clear next step: “SHOP ALL”.

    Social proof on the homepage: 1 customer or partner logo, a star rating and “14,000+ reviews”.

  • Analytics in place

    Analytics detected: TikTok Pixel.

  • Risk reducer mentioned

    A guarantee or risk reducer (money-back, free trial, no credit card or similar) is mentioned on the page.

Privacy and tracking

1 to fix

  • 4 trackers load before any consent

    4

    Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Klaviyo (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.

  • 14 cookies set on arrival

    14

    Opening the homepage sets 14 cookies (measured from a US location before any click).

  • No consent tool detected

  • 25 other companies contacted

    Loading the homepage contacts 25 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

Security, domain, email and software versions

The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at yourheights.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
