Speed

6 to fix61
  • Render-blocking requests

    2.6 s

    12 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.6 s.

  • Mobile performance score: 61

    61/100

    Your mobile performance score is 61. Pages that score under 90 lose visitors before the first paint.

  • Improve image delivery

    500 ms · 250 KiB

    17 images could be 250 KiB 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.

  • Use efficient cache lifetimes

    400 ms · 66 KiB

    6 files are served with short cache lifetimes, so returning visitors download them again (66 KiB).

  • Reduce unused JavaScript

    300 ms · 83 KiB

    About 83 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

  • Shopify adds 108 ms

    108 ms

    Shopify costs a phone 108 ms of main-thread work and 318 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.

  • 5 third-party services on the page

    5 third-party services load with your homepage (Heroku, Shopify and Cloudflare CDN and others), adding 564 KiB and 275 ms of main-thread time.

  • Legacy JavaScript

    150 ms · 16 KiB

    Polyfills for old browsers add 16 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

  • Reduce unused CSS

    40 ms · 27 KiB

    About 27 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 40 ms faster on a phone.

  • Font display

    50 ms

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

  • 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.

  • Forced reflow

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

2 checks passed
  • Main-thread work: 1.7 s

    A phone's processor spends 1.7 s on main-thread work while loading, 652 ms of it running JavaScript. That is comfortably low.

  • Server response: 9 ms

    9 ms

    Your server sent the HTML in 9 ms, well inside Google's 600 ms guideline.

Core Web Vitals

5 to fix67
  • Largest Contentful Paint: 10.9 s

    10.9 s

    Your largest element takes 10.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

  • Time to Interactive: 11.0 s

    11.0 s

    The page becomes fully interactive after 11.0 s. Good is under 3.8 s.

  • First Contentful Paint: 4.0 s

    4.0 s

    The first text or image appears after 4.0 s on a phone. Good is under 1.8 s.

  • Speed Index: 7.1 s

    7.1 s

    Visually, the page fills in at 7.1 s (Speed Index). Good is under 3.4 s.

  • 11 images without width and height

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

  • Not enough real-visitor data yet

    Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

2 checks passed
  • Cumulative Layout Shift: 0

    0

    The layout barely moves while loading (CLS 0, good is under 0.1).

  • Total Blocking Time: 0 ms

    0 ms

    Scripts block the page for only 0 ms while loading. Good is under 200 ms.

Images and page weight

1 to fix85
  • Page weight: 3.0 MB in 244 requests

    3.0 MB

    Your homepage downloads 3.0 MB in 244 requests on a phone: images 1.3 MB (27), other files 742 KiB (93) and scripts 664 KiB (103). Under 2 MB keeps phones on slow connections fast.

  • 1 image in older formats

    1 image (74 KiB) is JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

  • 1 image below the first screen load straight away

    1 image further down the page (74 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

  • About 0.9 g of CO₂ per visit

    0.86 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.86 g of CO₂e: 103.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 checks passed
  • Images are sized for phones

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

Accessibility

7 to fixGoogle 8591
  • 1 button without a name

    1 button has no accessible name, so screen readers announce just “button”.

  • 3 tap targets too small

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

  • All page content should be contained by landmarks (32 elements)

    All page content should be contained by landmarks: 32 elements on the page fail this check, rated moderate by axe-core.

  • No main landmark

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

  • Page should contain a level-one heading (1 element)

    Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

  • 5 links without text

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

  • 1 form field without a label

    1 form field has no label, so screen readers announce an empty box and autofill guesses.

  • Headings skip levels

    Headings skip levels (h2 → h4 and h3 → h5), which makes the page harder to scan with a screen reader.

2 checks passed
  • Every image has alt text

    All 36 images in the HTML carry an alt attribute.

  • 44 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 51 WCAG 2.2 A/AA and best-practice rules on the phone render: 44 passed and 7 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

4 to fixGoogle 9280
  • No H1 headline

    There is no <h1>, so neither visitors nor Google get a clear main headline.

  • No structured data

    No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

  • Meta description is long (320 characters)

    Your meta description is 320 characters; Google truncates after about 160, so the end of your pitch is cut.

  • 16 links crawlers can't follow

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

  • 75 internal links, 3 external

    The homepage links to 75 pages on lumight.com and 3 external pages.

5 checks passed
  • Title: 37 characters

    Your title is a healthy 37 characters: “Lumight - Top US LED lighting company”.

  • Canonical URL set

    The canonical URL is https://lumight.com/.

  • 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://lumight.com/sitemap.xml.

AI search readiness

1 to fix88
  • No Organization structured data

    There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

3 checks passed
  • AI answer engines may read the site

    Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.

  • Text is in the HTML

    Your server sends the page's text in the HTML (675 words), so crawlers that don't run JavaScript still read it.

  • llms.txt published

    The site publishes https://lumight.com/llms.txt (5 KiB, 8 links), a plain-text guide to the site for AI tools.

Other pages

1 to fix95
  • 10 pages without a meta description

    https://lumight.com/collections/outdoor-1, https://lumight.com/collections/architectural, https://lumight.com/collections/cutoff, https://lumight.com/collections/traditional, https://lumight.com/collections/fabricator and https://lumight.com/collections/slingshot and 4 others have no meta description, so Google writes the search snippet from whatever text it finds.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 43 found) and read each the way a search engine does.

6 checks passed
  • Linked pages load

    All 15 pages we checked loaded without an error.

  • Canonical URLs point to themselves

    No page we checked hands its ranking to a different URL.

  • Titles are unique

    Every page we checked has its own title.

  • Every page has an H1

    Each page we checked has a main headline.

  • No linked page is hidden from search

    None of the pages we checked carries a noindex tag.

  • Every page has a title

    All 15 pages that loaded have a <title>.

Best practices

2 to fixGoogle 9287
  • 11 small tap targets

    11 of 45 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

  • 1 JavaScript error while loading

    1 error was logged to the browser console while the page loaded, for example “Handlebars is not defined”.

  • 1 low-resolution image

    1 image is served at too low a resolution for sharp phone screens.

1 checks passed
  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

4 to fix69
  • No call to action on the first screen

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

  • Local business without LocalBusiness data

    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.

  • Thin social proof

    Social proof on the homepage: 8 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

  • No analytics detected

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

  • No opening hours

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

  • No map or directions link

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

  • No risk reducer

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

  • About 674 words of copy

    The homepage carries about 674 words of visible text.

4 checks passed
  • 21 calls to action

    The homepage has 21 calls to action, for example “Contact”, “Shop Now” and “Subscribe”.

  • 2 short forms

    2 short forms (1 field at most) are right on the homepage.

  • Direct contact links

    Visitors can reach you directly: 1 phone link and 2 email links.

  • Phone number on the homepage

    Your phone number is on the homepage as a tap-to-call link.

Privacy and tracking

1 to fix
  • 3 trackers load before any consent

    3

    Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager 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.

  • 9 cookies set on arrival

    9

    Opening the homepage sets 9 cookies (measured from a US location before any click).

  • No consent tool detected

    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.

  • 14 other companies contacted

    Loading the homepage contacts 14 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 lumight.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.

Apps on your store

Your storefront loads 5 apps. Each one is code from another company running for your shoppers.

Apps your storefront loads
