Compare side by sideOne score from every part of this review. How it works
Speed
Render-blocking requests
900 ms2 files block the first paint until they finish downloading. Deferring or inlining them could save about 900 ms.
4 third-party services on the page
4 third-party services load with your homepage (Google Tag Manager, Bootstrap CDN and Google Analytics and others), adding 354 KiB and 174 ms of main-thread time.
Reduce unused CSS
150 ms · 34 KiBAbout 34 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.
Reduce unused JavaScript
139 KiBAbout 139 KiB of JavaScript is downloaded but never used on this page.
2 long tasks on the main thread
2 long tasks block the main thread while loading, the longest for 123 ms. During a long task the page ignores taps.
Use efficient cache lifetimes
54 KiB2 files are served with short cache lifetimes, so returning visitors download them again (54 KiB).
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.

Mobile performance score: 91
91/100Your mobile performance score is 91. That is in Google's “good” band (90 and up).
Main-thread work: 0.3 s
A phone's processor spends 0.3 s on main-thread work while loading, 151 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
Cumulative Layout Shift: 0.183
0.183The layout shifts by 0.183 while loading, so content jumps under the reader's thumb. Good is under 0.1.
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.

Time to Interactive: 3.6 s
3.6 sThe page is fully interactive after 3.6 s.
First Contentful Paint: 1.5 s
1.5 sThe first text or image appears after 1.5 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 “This domain is for sale.”.
Speed Index: 1.5 s
1.5 sVisually, the page fills in at 1.5 s (Speed Index), inside the 3.4 s “good” threshold.
Total Blocking Time: 41 ms
41 msScripts block the page for only 41 ms while loading. Good is under 200 ms.
Images and page weight
About 0.1 g of CO₂ per visit
0.11 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.11 g of CO₂e: 13.6 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: 410 KiB in 8 requests
410 KiBYour homepage downloads 410 KiB in 8 requests on a phone: scripts 288 KiB (2), images 53 KiB (1) and HTML 47 KiB (2). 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
2 text elements with low contrast
2 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
Links look like plain text
1 link inside paragraphs relies on colour alone to stand out.
<object> elements must have alternative text (1 element)
<object> elements must have alternative text: 1 element on the page fails this check, rated serious by axe-core.
1 image without alt text
1 image has no alt text, which hurts accessibility and image search.
All page content should be contained by landmarks (5 elements)
All page content should be contained by landmarks: 5 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
22 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 28 WCAG 2.2 A/AA and best-practice rules on the phone render: 22 passed and 6 failed. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
robots.txt blocks all crawlers
Your robots.txt disallows the whole site for every crawler, so search engines are told to stay out.
No meta description
No meta description, so Google writes its own snippet from whatever text it finds.
Blocked from indexing
Google's crawler is blocked from indexing this page.
Title is short (29 characters)
Your title is only 29 characters: “porkbun.com | domain for sale”. 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 http://vax.world/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
One H1 headline
Your main headline reads: “This domain is for sale.”.
AI search readiness
robots.txt blocks 6 AI answer engine crawlers
6 of 6Your robots.txt shuts out ChatGPT search (OAI-SearchBot), ChatGPT (ChatGPT-User), Claude search (Claude-SearchBot), Claude (Claude-User), Perplexity (PerplexityBot) and Perplexity (Perplexity-User). These fetch pages to answer people's questions and cite the source, so your site can't be quoted or linked in those answers.
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://vax.world/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 5 crawlers
robots.txt blocks GPTBot, ClaudeBot, Google-Extended, Applebot-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.
Best practices
2 checks passed
No console errors
No JavaScript errors were logged while the page loaded on a phone.
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 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 28 words
The homepage has only about 28 words of visible text; thin pages give Google and first-time buyers little to go on.
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.
2 checks passed
1 short form
A short form (1 field at most) is right on the homepage.
Analytics in place
Analytics detected: Google Analytics.
Privacy and tracking
2 trackers load before any consent
2Before a visitor clicks anything, the page loads Google Analytics and 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.
3 cookies set on arrival
3Opening the homepage sets 3 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.
4 other companies contacted
Loading the homepage contacts 4 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 vax.world, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
