Speed

10 to fix52
  • Use efficient cache lifetimes

    8.7 s · 3.0 MB

    49 files are served with short cache lifetimes, so returning visitors download them again (3.0 MB).

  • Improve image delivery

    3.5 s · 850 KiB

    5 images could be 850 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 3.5 s faster on a phone.

  • Reduce unused JavaScript

    2.7 s · 1.1 MB

    About 1.1 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.7 s faster on a phone.

  • Render-blocking requests

    2.2 s

    12 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.2 s.

  • Mobile performance score: 52

    52/100

    Your mobile performance score is 52 (desktop: 58). Pages that score under 90 lose visitors before the first paint.

  • 8 third-party services on the page

    8 third-party services load with your homepage (Google Tag Manager, Vimeo and Civic and others), adding 1.8 MB and 682 ms of main-thread time.

  • Reduce unused CSS

    450 ms · 62 KiB

    About 62 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

  • Google Tag Manager adds 360 ms

    360 ms

    Google Tag Manager costs a phone 360 ms of main-thread work and 516 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.

  • Main-thread work: 3.2 s

    A phone's processor spends 3.2 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • Vimeo adds 121 ms

    121 ms

    Vimeo costs a phone 121 ms of main-thread work and 1.0 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.

  • 15 long tasks on the main thread

    15 long tasks block the main thread while loading, the longest for 175 ms. During a long task the page ignores taps.

  • Legacy JavaScript

    58 KiB

    Polyfills for old browsers add 58 KiB JavaScript that modern phones do not need.

  • 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.

  • Minify JavaScript

    2 KiB

    2 KiB could be saved by minifying JavaScript.

1 checks passed
  • Server response: 8 ms

    8 ms

    Your server sent the HTML in 8 ms, well inside Google's 600 ms guideline.

Core Web Vitals

11 to fix67
  • 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: 5.8 s

    5.8 s

    Real visitors wait 5.8 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • Real-user FCP: 5.3 s

    5.3 s

    Real visitors see the first content after 5.3 s (75th percentile). Good is under 1.8 s.

  • Real-user TTFB: 4.2 s

    4.2 s

    Real visitors wait 4.2 s for your server to start answering (75th percentile). Good is under 800 ms.

  • Largest Contentful Paint: 16.0 s

    16.0 s

    Your largest element takes 16.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

  • Speed Index: 13.8 s

    13.8 s

    Visually, the page fills in at 13.8 s (Speed Index). Good is under 3.4 s.

  • Time to Interactive: 21.3 s

    21.3 s

    The page becomes fully interactive after 21.3 s. Good is under 3.8 s.

  • Largest content (LCP) got 55% slower for real visitors

    +55%

    Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 3.3 s to 5.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • First Contentful Paint: 2.9 s

    2.9 s

    The first text or image appears after 2.9 s on a phone. Good is under 1.8 s.

  • Total Blocking Time: 347 ms

    347 ms

    Scripts block taps and scrolling for 347 ms in total while the page loads. Good is under 200 ms.

  • 11 images without width and height

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

  • Tap response (INP) got 11% slower for real visitors

    +11%

    Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 151 ms to 178 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

3 checks passed
  • Real-user INP: 180 ms

    180 ms

    Real visitors wait 180 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

  • Real-user CLS: 0.00

    0.00

    For real visitors the layout shifts by 0.00 (75th percentile). Good is under 0.1.

  • Cumulative Layout Shift: 0

    0

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

Images and page weight

4 to fix43
  • Page weight: 4.9 MB in 102 requests

    4.9 MB

    Your homepage downloads 4.9 MB in 102 requests on a phone: images 2.4 MB (22), scripts 2.0 MB (32) and fonts 204 KiB (6). Under 2 MB keeps phones on slow connections fast.

  • 8 images in older formats

    8 images (924 KiB) 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.

  • 5 images below the first screen load straight away

    5 images further down the page (728 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

  • 5 images far larger than shown

    52 KiB

    5 images are downloaded at several times the size a phone draws them, for example SimRT.jpg at 900 px wide, shown at 294 px. Resized copies would save about 52 KiB.

  • About 1.4 g of CO₂ per visit

    1.38 g

    By the Sustainable Web Design model, a visit to your homepage emits about 1.38 g of CO₂e: 165.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Accessibility

4 to fixGoogle 8694
  • 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.

  • 42 images without alt text

    42 images have no alt text, which hurts accessibility and image search.

  • 5 links without text

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

  • 2 form fields without a label

    2 form fields have no label, so screen readers announce an empty box and autofill guesses.

  • Headings skip levels

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

1 checks passed
  • 46 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 50 WCAG 2.2 A/AA and best-practice rules on the phone render: 46 passed and 4 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

2 to fixGoogle 9287
  • No H1 headline

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

  • No social preview image

    No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

  • 100 internal links, 22 external

    The homepage links to 100 pages on visionrt.com and 22 external pages.

6 checks passed
  • Meta description: 156 characters

    Your meta description is 156 characters: “Vision RT is the inventor of Surface Guided Radiation Therapy (SGRT) and produces a range of innovative radiotherapy so…”.

  • Title: 37 characters

    Your title is a healthy 37 characters: “Vision RT | Innovative SGRT Solutions”.

  • Canonical URL set

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

  • Structured data in place

    Structured data found: BreadcrumbList, Organization, WebPage and WebSite.

  • 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.visionrt.com/sitemap_index.xml.

AI search readiness

100
  • No llms.txt

    There is no https://visionrt.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: 4 of 6 facts

    Your Organization JSON-LD gives name, url, logo and sameAs (social profiles); description and contact details would complete it.

  • Text is in the HTML

    Your server sends the page's text in the HTML (1,234 words), so crawlers that don't run JavaScript still read it.

Other pages

1 to fix95
  • 4 pages without an H1

    https://visionrt.com/contact-us, https://visionrt.com/introduction-to-sgrt, https://visionrt.com/getting-started-with-sgrt and https://visionrt.com/sgrtaccess have no <h1> headline, so visitors and search engines get no clear main topic.

  • 10 pages slow to respond

    https://visionrt.com/about-us, https://visionrt.com/contact-us, https://visionrt.com/leadership, https://visionrt.com/news, https://visionrt.com/introduction-to-sgrt and https://visionrt.com/getting-started-with-sgrt and 4 others took over 3 s to send their HTML from our server.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 66 found) and read each the way a search engine does.

6 checks passed

  • Every page has a title

    All 15 pages that loaded have a <title>.

Best practices

2 to fixGoogle 5894
  • 2 third-party cookies

    2 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

  • Deprecated browser APIs

    The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

  • Browser-reported issues

    Chrome logged issues while loading the page (“Cookie”).

3 checks passed
  • No console errors

    No JavaScript errors were logged while the page loaded on a phone.

  • Tap targets are thumb-sized

  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

1 to fix92
  • Thin social proof

    Social proof on the homepage: 5 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

  • 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 788 words of copy

    The homepage carries about 788 words of visible text.

5 checks passed
  • Clear next step on the first screen

    On a phone, the first screen shows a clear next step: “Contact Us”.

  • 3 calls to action

    The homepage has 3 calls to action, for example “Contact / Careers”, “Contact Us” and “Contact”.

  • 2 short forms

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

  • Analytics in place

    Analytics detected: Google Tag Manager and Microsoft Clarity.

  • Direct contact links

    Visitors can reach you directly: 0 phone links and 3 email links.

Privacy and tracking

1 to fix
  • 4 trackers load before any consent

    4

    Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Microsoft Clarity (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.

  • 6 cookies set on arrival

    6

    Opening the homepage sets 6 cookies, 2 of them by other companies (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.

  • 28 other companies contacted

    Loading the homepage contacts 28 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 visionrt.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
