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
Use efficient cache lifetimes
137.9 s · 25.8 MB22 files are served with short cache lifetimes, so returning visitors download them again (25.8 MB).
Improve image delivery
136.9 s · 25.7 MB18 images could be 25.7 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 136.9 s faster on a phone.
Reduce unused JavaScript
3.6 s · 703 KiBAbout 703 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.6 s faster on a phone.
Render-blocking requests
3.8 s6 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.8 s.
Reduce unused CSS
1.4 s · 251 KiBAbout 251 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.4 s faster on a phone.
6 third-party services on the page
6 third-party services load with your homepage (Google Tag Manager, harmanpro.com and jQuery CDN and others), adding 27.9 MB and 455 ms of main-thread time.
harmanpro.com adds 131 ms
131 msharmanpro.com costs a phone 131 ms of main-thread work and 27.3 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.
Mobile performance score: 56
56/100Your mobile performance score is 56. Pages that score under 90 lose visitors before the first paint.
Google Tag Manager adds 167 ms
167 msGoogle Tag Manager costs a phone 167 ms of main-thread work and 319 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 long tasks on the main thread
5 long tasks block the main thread while loading, the longest for 101 ms. During a long task the page ignores taps.
Font display
50 msWeb fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).
Document request latency
22 KiBThe HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.
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: 1.2 s
A phone's processor spends 1.2 s on main-thread work while loading, 521 ms of it running JavaScript. That is comfortably low.
Server response: 2 ms
2 msYour server sent the HTML in 2 ms, well inside Google's 600 ms guideline.
Core Web Vitals
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: 143.4 s
143.4 sYour largest element takes 143.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “VTX B35”.
Speed Index: 20.3 s
20.3 sVisually, the page fills in at 20.3 s (Speed Index). Good is under 3.4 s.
Time to Interactive: 143.4 s
143.4 sThe page becomes fully interactive after 143.4 s. Good is under 3.8 s.
First Contentful Paint: 4.7 s
4.7 sThe first text or image appears after 4.7 s on a phone. Good is under 1.8 s.
Real-user CLS: 0.19
0.19For real visitors the layout shifts by 0.19 (75th percentile). Good is under 0.1.
Real-user TTFB: 909 ms
909 msReal visitors wait 909 ms for your server to start answering (75th percentile). Good is under 800 ms.
37 images without width and height
37 images have no width and height attributes, so the layout jumps as each one loads.
7 checks passed
Real-user LCP: 2.3 s
2.3 sReal visitors wait 2.3 s for the largest content to appear (75th percentile). Good is under 2.5 s.
Real-user INP: 105 ms
105 msReal visitors wait 105 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.
Real-user FCP: 1.6 s
1.6 sReal visitors see the first content after 1.6 s (75th percentile). Good is under 1.8 s.
Tap response (INP) got 16% faster for real visitors
-16%Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 202 ms to 152 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).
Largest content (LCP) got 24% faster for real visitors
-24%Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.9 s to 2.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).
Total Blocking Time: 98 ms
98 msScripts block the page for only 98 ms while loading. Good is under 200 ms.
Cumulative Layout Shift: 0
0The layout barely moves while loading (CLS 0, good is under 0.1).
Images and page weight
Page weight: 28.0 MB in 75 requests
28.0 MBYour homepage downloads 28.0 MB in 75 requests on a phone: images 26.3 MB (40), scripts 1.2 MB (11) and stylesheets 271 KiB (2). Under 2 MB keeps phones on slow connections fast.
6 images over 500 KB
6 images weigh 24.9 MB together. On a phone connection a single image that size takes seconds.
12 images far larger than shown
24.9 MB12 images are downloaded at several times the size a phone draws them, for example 6a6031331fcd0af676cb3001c6f59257.png at 6,000 px wide, shown at 290 px. Resized copies would save about 24.9 MB.
6 images in older formats
6 images (20.3 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.
An image on the first screen is lazy-loaded
6a6031331fcd0af676cb3001c6f59257.png 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).
About 7.9 g of CO₂ per visit
7.93 gBy the Sustainable Web Design model, a visit to your homepage emits about 7.93 g of CO₂e: 951.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
Accessibility
1 text element with low contrast
1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.
All page content should be contained by landmarks (8 elements)
All page content should be contained by landmarks: 8 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.
Alternative text of images should not be repeated as text (1 element)
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
Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.
2 checks passed
Every image has alt text
All 35 images in the HTML carry an alt attribute.
37 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: 37 passed and 6 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
No meta description
No meta description, so Google writes its own snippet from whatever text it finds.
No H1 headline
There is no <h1>, so neither visitors nor Google get a clear main headline.
7 links crawlers can't follow
7 links have no real href, so search engines can't follow them.
68 internal links, 25 external
The homepage links to 68 pages on jblpro.com and 25 external pages.
6 checks passed

AI search readiness
No llms.txt
There is no https://jblpro.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.
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.
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 (192 words), so crawlers that don't run JavaScript still read it.
Other pages
1 linked page hidden from search
https://jblpro.com/en-US/promotions is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.
3 pages without a meta description
https://jblpro.com/en-US/promotions, https://jblpro.com/en-US/learning-sessions and https://jblpro.com/en-US/innovation have no meta description, so Google writes the search snippet from whatever text it finds.

Mobile viewport set
The page declares a mobile viewport.
Content and conversion
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.
Only about 201 words
The homepage has only about 201 words of visible text; thin pages give Google and first-time buyers little to go on.
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.
5 checks passed
Clear next step on the first screen
On a phone, the first screen shows a clear next step: “Where To Buy & Connect” and “WHERE TO BUY & CONNECT”.
4 calls to action
The homepage has 4 calls to action, for example “Where To Buy & Connect”, “Join our mailing list” and “Join Our Mailing List”.
1 short form
A short form (1 field at most) is right on the homepage.
Social proof on the page
Social proof on the homepage: 1 testimonial or review block and 9 customer or partner logos.
Analytics in place
Analytics detected: Google Analytics.
Privacy and tracking
3 trackers load before any consent
3Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager and HubSpot (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.
7 cookies set on arrival
7Opening the homepage sets 7 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 jblpro.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
