Speed

7 to fix63
  • Use efficient cache lifetimes

    1.1 s · 193 KiB

    13 files are served with short cache lifetimes, so returning visitors download them again (193 KiB).

  • Mobile performance score: 63

    63/100

    Your mobile performance score is 63 (desktop: 99). Pages that score under 90 lose visitors before the first paint.

  • Reduce unused JavaScript

    450 ms · 57 KiB

    About 57 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

  • 8 third-party services on the page

    8 third-party services load with your homepage (Google Tag Manager, Hubspot and usemessages.com and others), adding 2.0 MB and 268 ms of main-thread time.

  • 5 long tasks on the main thread

    5 long tasks block the main thread while loading, the longest for 285 ms. During a long task the page ignores taps.

  • Main-thread work: 2.2 s

    A phone's processor spends 2.2 s on main-thread work while loading, 827 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • b-cdn.net adds 0 ms

    0 ms

    b-cdn.net costs a phone 0 ms of main-thread work and 1.4 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.

  • Reduce unused CSS

    11 KiB

    About 11 KiB of CSS is downloaded but never applied on this page.

  • Phones get a much slower page than desktops

    Desktop scores 99 but mobile only 63. A gap that wide usually means heavy scripts and images that hit phones hardest.

  • 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.

1 checks passed
  • Server response: 4 ms

    4 ms

    Your server sent the HTML in 4 ms, well inside Google's 600 ms guideline.

Core Web Vitals

5 to fix60
  • Largest Contentful Paint: 6.5 s

    6.5 s

    Your largest element takes 6.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Threat overlap”.

  • First Contentful Paint: 2.8 s

    2.8 s

    The first text or image appears after 2.8 s on a phone. Good is under 1.8 s.

  • Time to Interactive: 6.5 s

    6.5 s

    The page becomes fully interactive after 6.5 s. Good is under 3.8 s.

  • Total Blocking Time: 358 ms

    358 ms

    Scripts block taps and scrolling for 358 ms in total while the page loads. Good is under 200 ms.

  • Speed Index: 3.4 s

    3.4 s

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

  • 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.

1 checks passed
  • Cumulative Layout Shift: 0.005

    0.005

    The layout barely moves while loading (CLS 0.005, good is under 0.1).

Images and page weight

1 to fix85
  • Page weight: 2.0 MB in 37 requests

    2.0 MB

    Your homepage downloads 2.0 MB in 37 requests on a phone: media 1.4 MB (2), scripts 282 KiB (12) and fonts 207 KiB (5). Under 2 MB keeps phones on slow connections fast.

  • About 0.6 g of CO₂ per visit

    0.57 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.57 g of CO₂e: 68.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 checks passed
  • 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

6 to fixGoogle 8390
  • 1 button without a name

    1 button has no accessible name, so screen readers announce just “button”.

  • 3 tap targets too small

    3 tap targets are too small or too close together to hit reliably with a finger.

  • 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 (35 elements)

    All page content should be contained by landmarks: 35 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.

2 checks passed
  • Every image has alt text

    All 10 images in the HTML carry an alt attribute.

  • 36 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 42 WCAG 2.2 A/AA and best-practice rules on the phone render: 36 passed and 6 failed. 2 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

4 to fixGoogle 9280
  • No H1 headline

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

  • Meta description is long (196 characters)

    Your meta description is 196 characters; Google truncates after about 160, so the end of your pitch is cut.

  • Structured data has 2 problems

    Structured data found (BreadcrumbList, LocalBusiness, Organization and WebSite) but with 2 problems, for example “LocalBusiness: missing name”.

  • 3 links with vague text

    3 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

  • Open Graph partly set

    Open Graph is missing og:description, so shared links fall back to guesses.

  • 71 internal links, 2 external

    The homepage links to 71 pages on centripetal.ai and 2 external pages.

4 checks passed
  • Title: 41 characters

    Your title is a healthy 41 characters: “Real-time Threat Prevention | Centripetal”.

  • Canonical URL set

    The canonical URL is https://www.centripetal.ai/.

  • 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.centripetal.ai/sitemap.xml.

AI search readiness

100
4 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 (944 words), so crawlers that don't run JavaScript still read it.

  • llms.txt published

    The site publishes /llms.txt (92 KiB, 309 links), a plain-text guide to the site for AI tools.

Other pages

2 to fix93
  • 8 pages share a meta description

    /customer-stories, /threat-research, /get-a-demo, /support, /partners and /contact and 2 others use the same meta description. A description written for each page earns more clicks.

  • 2 pages without an H1

    /contact and /es-latam have no <h1> headline, so visitors and search engines get no clear main topic.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 30 found) and read each the way a search engine does.

6 checks passed
  • Linked pages load

    9 pages of 15 loaded without an error (the rest turned automated requests away).

  • Canonical URLs point to themselves

    No page we checked hands its ranking to a different URL.

  • Every page has a meta description

    All 9 pages that loaded have a meta description.

  • Titles are unique

    Every page we checked has its own title.

  • No linked page is hidden from search

    None of the pages we checked carries a noindex tag.

  • Every page has a title

    All 9 pages that loaded have a <title>.

Best practices

1 to fixGoogle 10093

2 checks passed
  • Tap targets are thumb-sized

    37 of 46 tappable elements near the top are at least 24 px.

  • Mobile viewport set

    The page declares a mobile viewport.

Security and trust

100
  • Short HSTS lifetime

    HSTS is set, but max-age is 30 days; one year is the recommended minimum.

  • No Permissions-Policy

    No Permissions-Policy header to switch off camera, microphone and location for embedded content.

  • No security.txt

    There is no /.well-known/security.txt telling researchers how to report a security problem to you.

7 checks passed
  • Served over HTTPS

    The homepage is served over HTTPS (centripetal.ai).

  • Valid certificate (66 days left)

    The certificate from Let's Encrypt · YE1 verifies for centripetal.ai and is valid for another 66 days.

  • Protected from clickjacking

    X-Frame-Options or a frame-ancestors policy stops other sites framing yours.

  • Content-Security-Policy set

    A Content-Security-Policy is set, the main browser-side defence against injected scripts.

  • http:// redirects to https

    http://centripetal.ai redirects to the secure version.

  • HTTP/2 and HTTP/3

    The server speaks HTTP/2 and advertises HTTP/3, so browsers load many files over one connection.

  • All 34 links work

    All 34 links checked from your homepage (32 internal, 2 external) answered without errors.

Domain and trust

  • No CAA record

    centripetal.ai has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

  • DNSSEC is off

    centripetal.ai's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

2 checks passed
  • Domain is 6 years old

    6 years

    centripetal.ai was registered in Dec 2019 through GoDaddy.com, LLC. An established domain carries more trust with email providers and search engines.

  • Registered until Dec 2027

    centripetal.ai is registered until Dec 2027.

Content and conversion

2 to fix88
  • 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 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.

  • About 728 words of copy

    The homepage carries about 728 words of visible text.

6 checks passed
  • Clear next step on the first screen

    On a phone, the first screen shows a clear next step: “Get a Demo” and “CONTACT”.

  • 2 short forms

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

  • Social proof on the page

    Social proof on the homepage: 7 testimonial or review blocks and 1 customer or partner logo.

  • Analytics in place

    Analytics detected: Google Tag Manager, Google Analytics and HubSpot.

  • LocalBusiness structured data

    Your homepage describes the business with LocalBusiness JSON-LD, so search engines and AI assistants can read its address, hours and phone reliably.

Email authentication

90
  • Email authentication score: 90/100

    Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

3 checks passed
  • DMARC policy: quarantine

    DMARC tells receivers to quarantine mail that fails authentication, and sends you reports.

  • SPF with a strict ending (-all)

    An SPF record lists your sending servers and tells receivers to reject anything else: “v=spf1 include:_spf.google.com include:3851017.spf08.hubspotemail.net -all”.

  • DKIM signing found

    A DKIM key is published (selector “google”), so receivers can verify mail really came from you.

Privacy and tracking

  • 3 trackers load before any consent

    3

    Before a visitor clicks anything, the page loads Google Ads, Google Tag Manager and HubSpot (measured from a US location before any click). A consent tool (HubSpot cookie banner) is installed; check it blocks these until visitors agree where the law requires it.

  • 2 cookies set on arrival

    2

    Opening the homepage sets 2 cookies (measured from a US location before any click).

  • 17 other companies contacted
