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
150 ms · 33 KiB4 files are served with short cache lifetimes, so returning visitors download them again (33 KiB).
Reduce unused JavaScript
150 ms · 29 KiBAbout 29 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.
Render-blocking requests
150 ms1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 150 ms.
Improve image delivery
8 KiB1 image could be 8 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.
Document request latency
2 KiBThe HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.
3 checks passed
Mobile performance score: 100
100/100Your mobile performance score is 100 (desktop: 100). That is in Google's “good” band (90 and up).
Main-thread work: 0.1 s
A phone's processor spends 0.1 s on main-thread work while loading, 20 ms of it running JavaScript. That is comfortably low.
Server response: 1 ms
1 msYour server sent the HTML in 1 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.
Real-user LCP: 3.0 s
3.0 sReal visitors wait 3.0 s for the largest content to appear (75th percentile). Good is under 2.5 s.
Real-user INP: 328 ms
328 msReal visitors wait 328 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.
Real-user CLS: 0.20
0.20For real visitors the layout shifts by 0.20 (75th percentile). Good is under 0.1.
Real-user FCP: 2.4 s
2.4 sReal visitors see the first content after 2.4 s (75th percentile). Good is under 1.8 s.
Real-user TTFB: 1.2 s
1.2 sReal visitors wait 1.2 s for your server to start answering (75th percentile). Good is under 800 ms.
2 images without width and height
2 images have no width and height attributes, so the layout jumps as each one loads.

Tap response (INP) got 11% faster for real visitors
-11%Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' tap response (inp) went from 366 ms to 319 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

-42%Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 5.5 s to 3.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).
Cumulative Layout Shift: 0.008
0.008The layout barely moves while loading (CLS 0.008, good is under 0.1).
First Contentful Paint: 0.8 s
0.8 sThe first text or image appears after 0.8 s, inside the 1.8 s “good” threshold.
Largest Contentful Paint: 1.5 s
1.5 sYour largest element renders in 1.5 s on a phone, inside Google's 2.5 s “good” threshold. The largest element is the text “Please check your connection, disable any ad blockers, or t…”.
Speed Index: 0.8 s
0.8 sVisually, the page fills in at 0.8 s (Speed Index), inside the 3.4 s “good” threshold.
Total Blocking Time: 0 ms

Time to Interactive: 1.5 s
1.5 sThe page is fully interactive after 1.5 s.
Images and page weight
About 0.04 g of CO₂ per visit
0.04 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.04 g of CO₂e: 5.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
4 checks passed
Page weight: 151 KiB in 10 requests
151 KiBYour homepage downloads 151 KiB in 10 requests on a phone: fonts 77 KiB (1), scripts 48 KiB (2) and other files 10 KiB (3). That is a lean page.
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
All page content should be contained by landmarks (6 elements)
All page content should be contained by landmarks: 6 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.
1 checks passed
32 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 33 WCAG 2.2 A/AA and best-practice rules on the phone render: 32 passed and 1 failed. 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.
Title is short (16 characters)
Your title is only 16 characters: “Client Challenge”. Between 30 and 65 characters leaves room to say what you do and for whom.
No structured data
No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.
No canonical URL
No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.
No social preview image
No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.
No XML sitemap
No XML sitemap at https://www.jstor.org/sitemap.xml, so Google discovers your pages only by following links.
Only 0 internal links
The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.
No favicon declared
No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.
No X (Twitter) card tag
No twitter:card tag. X falls back to Open Graph, which is incomplete here.
1 checks passed
robots.txt in place
robots.txt is in place and points crawlers to your sitemap.
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.jstor.org/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.
Opted out of AI training for 4 crawlers
robots.txt blocks GPTBot, ClaudeBot, Google-Extended and CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers, which the crawlers above handle.
1 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.
Best practices
1 JavaScript error while loading
1 error was logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 401 ()”.
1 checks passed
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.
No calls to action
We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.
No social proof
No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.
No analytics detected
No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.
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 13 words
The homepage has only about 13 words of visible text; thin pages give Google and first-time buyers little to go on.
No form on the homepage
There is no form on the homepage, so every lead has to click through to another page first.
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.
Privacy and tracking
1 cookie set on arrival
1Opening the homepage sets 1 cookie (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.
1 checks passed
No known trackers before consent
No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).
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 jstor.org, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
