Chrome UX Report (opens in a new tab): real Chrome visitors over rolling 28-day periods.
One score from every part of this review. How it works
Speed
Improve image delivery
6.4 s · 5.4 MB7 images could be 5.4 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 6.4 s faster on a phone.
Render-blocking requests
2.6 s10 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.6 s.
Mobile performance score: 58
58/100Your mobile performance score is 58 (desktop: 90). Pages that score under 90 lose visitors before the first paint.
Reduce unused JavaScript
760 ms · 138 KiBAbout 138 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 760 ms faster on a phone.
Reduce unused CSS
300 ms · 46 KiBAbout 46 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.
Use efficient cache lifetimes
200 ms · 12 KiB3 files are served with short cache lifetimes, so returning visitors download them again (12 KiB).
Legacy JavaScript
200 ms · 10 KiBPolyfills for old browsers add 10 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 200 ms faster on a phone.
5 third-party services on the page
5 third-party services load with your homepage (Google Tag Manager, Cloudflare CDN and Cloudflare and others), adding 232 KiB and 115 ms of main-thread time.
1 long task on the main thread
1 long task block the main thread while loading, the longest for 69 ms. During a long task the page ignores taps.
Phones get a much slower page than desktops
Desktop scores 90 but mobile only 58. A gap that wide usually means heavy scripts and images that hit phones hardest.
Minify CSS
6 KiB6 KiB could be saved by minifying CSS.
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.
2 checks passed
Main-thread work: 0.5 s
A phone's processor spends 0.5 s on main-thread work while loading, 118 ms of it running JavaScript. That is comfortably low.
Server response: 3 ms
3 msYour server sent the HTML in 3 ms, well inside Google's 600 ms guideline.
Core Web Vitals
Largest Contentful Paint: 22.4 s
22.4 sYour largest element takes 22.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.
Time to Interactive: 23.6 s
23.6 sThe page becomes fully interactive after 23.6 s. Good is under 3.8 s.
Speed Index: 11.1 s
11.1 sVisually, the page fills in at 11.1 s (Speed Index). Good is under 3.4 s.
First Contentful Paint: 4.1 s
4.1 sThe first text or image appears after 4.1 s on a phone. Good is under 1.8 s.
15 images without width and height
15 images have no width and height attributes, so the layout jumps as each one loads.

Images and page weight
5 images over 500 KB
5 images weigh 5.4 MB together. On a phone connection a single image that size takes seconds.
Page weight: 6.2 MB in 48 requests
6.2 MBYour homepage downloads 6.2 MB in 48 requests on a phone: images 5.6 MB (26), fonts 266 KiB (6) and scripts 244 KiB (9). Under 2 MB keeps phones on slow connections fast.
6 images far larger than shown
3.2 MB6 images are downloaded at several times the size a phone draws them, for example shutterstock_641035918-2.jpg at 1,000 px wide, shown at 263 px. Resized copies would save about 3.2 MB.
7 images in older formats
7 images (5.5 MB) are 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.
6 images below the first screen load straight away
6 images further down the page (4.3 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.
About 1.7 g of CO₂ per visit
1.75 gBy the Sustainable Web Design model, a visit to your homepage emits about 1.75 g of CO₂e: 209.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
Accessibility
3 text elements with low contrast
3 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
2 checks passed
Every image has alt text
All 22 images in the HTML carry an alt attribute.
42 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 43 WCAG 2.2 A/AA and best-practice rules on the phone render: 42 passed and 1 failed. 3 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
Title is long (68 characters)
Your title is 68 characters, so Google will cut it off around 60: “Sealed | Upgrade your home with insulation, HVAC and smart home tech”.
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 (174 characters)
Your meta description is 174 characters; Google truncates after about 160, so the end of your pitch is cut.
6 links with vague text
6 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.
32 internal links, 1 external
The homepage links to 32 pages on sealed.com and 1 external page.
5 checks passed
One H1 headline
Your main headline reads: “Sealed”.
Canonical URL set
The canonical URL is https://www.sealed.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://www.sealed.com/sitemap.xml.
AI search readiness
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.
No llms.txt
There is no https://www.sealed.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.
2 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 (576 words), so crawlers that don't run JavaScript still read it.
Other pages
9 pages share a meta description
https://www.sealed.com/contractors, https://www.sealed.com/homeowner, https://www.sealed.com/in-the-news, https://www.sealed.com/energy-star, https://www.sealed.com/homes-sample-application and https://www.sealed.com/implementing-measured-modeled and 3 others use the same meta description. A description written for each page earns more clicks.
3 pages without an H1
https://www.sealed.com/contractors, https://www.sealed.com/homeowner and https://www.sealed.com/programs have no <h1> headline, so visitors and search engines get no clear main topic.
12 internal pages checked
We fetched 12 pages linked from your homepage and read each the way a search engine does.
6 checks passed

Best practices
1 distorted image
1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.
3 checks passed
No console errors
No JavaScript errors were logged while the page loaded on a phone.
Tap targets are thumb-sized
14 of 16 tappable elements near the top are at least 24 px.
Mobile viewport set
The page declares a mobile viewport.
Content and conversion
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.
No phone number on the homepage
A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.
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.
No opening hours
The homepage shows no opening hours. If customers visit or call, show when.
No form on the homepage
There is no form on the homepage, so every lead has to click through to another page first.
No map or directions link
There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.
About 566 words of copy
The homepage carries about 566 words of visible text.
4 checks passed
3 calls to action
The homepage has 3 calls to action, for example “Get in touch” and “Learn more”.
Social proof on the page
Social proof on the homepage: 3 testimonial or review blocks and 2 customer or partner logos.
Analytics in place
Analytics detected: Google Tag Manager and Cloudflare Web Analytics.
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 tracker load before any consent
1Before a visitor clicks anything, the page loads Google Tag Manager (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.
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.
6 other companies contacted
Loading the homepage contacts 6 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 sealed.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
