Where is claritycheck.com hosted?
The first address resolves to infrastructure in Toronto, Canada.
The network is operated by Cloudflare, Inc. (AS13335 Cloudflare, Inc.).
Hosting location describes where the responding server sits, not where the business is. A CDN will report its nearest edge rather than the origin.
What is claritycheck.com running on?
claritycheck.com exposes 2 identifiable technologies: Next.js, Cloudflare.
The build output indicates a server-rendered JavaScript framework, which means the HTML served to crawlers is generated ahead of time rather than assembled in the browser.
Cloudflare sits in front of the origin, so the server header, IP addresses and response timing describe the edge rather than the machine actually running the site.
- Next.js
- Cloudflare
How does the homepage respond?
The server answered with HTTP 200 over
HTTPS.
At 406ms to first byte this response is unremarkable for a homepage measured from a single European location.
The HTML alone is 571KB before images, stylesheets or scripts are counted, which is heavy for a document that browsers must parse before anything renders.
The HTML is compressed with gzip.
| Server header | cloudflare |
|---|---|
| Compression | gzip |
| Page size | 584,875 bytes |
| Declared language | en |
| Mobile viewport | declared |

What does claritycheck.com load from third parties?

6 cookies are set before any interaction (NEXT_LOCALE, uuid, funnel_type, X-Country, country). 1 lacks the Secure flag.
The page links or refers to X/Twitter, LinkedIn.
| Cookie | Secure | HttpOnly | SameSite |
|---|---|---|---|
| NEXT_LOCALE | no | no | lax |
| uuid | yes | no | lax |
| funnel_type | yes | no | lax |
| X-Country | yes | no | lax |
| country | yes | no | lax |
| device_type | yes | no | lax |
Does claritycheck.com settle on one address?
Plain HTTP redirects to HTTPS, so visitors who type the bare address still land on the secure version.
The www address redirects to https://claritycheck.com/, so the site settles on one canonical hostname.
How easily can claritycheck.com be crawled?
A sitemap is served at https://claritycheck.com/sitemap.xml listing 329 entries.
The most recent lastmod date is 2026-10-02.
A deliberately invalid URL correctly returns HTTP 404, so missing pages will not be indexed.
What tracking does claritycheck.com run?
No analytics or advertising trackers were detected on the homepage of claritycheck.com, which is unusual for a commercial site.
How does claritycheck.com look when shared?
All five social preview tags are present, so links shared to social platforms and chat apps will render with a title, description and image.
The page declares 27 hreflang alternates (x-default, en, ar-SA, cs, de, el, es, es-ES, es-MX, et, fr, hr), so it targets more than one language or region.
How are images, fonts and scripts handled?
3 images on the homepage, 2 of them lazy-loaded (67%).
All image references use JPEG, PNG or GIF. WebP or AVIF typically cut image weight substantially at the same visual quality.
No srcset attributes are used, so every device is served the same image size regardless of screen.
The page pulls 2 external stylesheets and 5 external scripts, with 4 carrying defer or async.
Responses carry Cloudflare edge headers, so content is served from a CDN rather than straight from the origin.
Is claritycheck.com accessible and current?
The page uses 5 landmark elements and 98 ARIA attributes.
The viewport tag disables pinch-zoom. That fails WCAG 1.4.4 and is a genuine problem for anyone who needs to enlarge text.
There are 2 form inputs but only 1 label elements, so some fields may be unlabelled for screen readers.
No skip-to-content link was found, which keyboard users rely on to bypass navigation.
The visible copyright notice reads 2024, 2 years behind the current year, which usually indicates the site is not actively maintained.
Can search engines index claritycheck.com?
Nothing on the homepage prevents indexing: no noindex is set in the robots meta tag or the X-Robots-Tag header.
The homepage carries 54 internal and 0 external links across 0 outside hosts.
Visible text is only 1.6% of the HTML, which indicates the page is assembled in the browser rather than served as content.
How is claritycheck.com delivered?
The HTML is served with Cache-Control: no-store, must-revalidate.
HTTP/3 is advertised via alt-svc, so modern browsers will upgrade to QUIC after the first visit.
No favicon is declared in the markup.
Frequently asked questions
Does claritycheck.com set the usual HTTP security headers?
It sets 5 of 6. The ones not present are: Content Security Policy.
Does claritycheck.com allow AI crawlers?
robots.txt names no AI crawler specifically, so they fall under the wildcard rule, which does not disallow them.
What is claritycheck.com built with?
The homepage exposes these fingerprints: Next.js, Cloudflare. A site behind a CDN or rendered server-side may use more than it reveals.
Where does this data come from?
Every figure was measured by our own server on 4 October 2026: DNS lookups, one HTTPS request to the homepage, a TLS handshake and a request for robots.txt. No third-party SEO API is involved.
Is any of this traffic or authority data?
No. Traffic, authority and ranking figures cannot be measured by inspecting a domain, only modelled. Everything here is a direct observation.
I own claritycheck.com and want this page removed.
Ask through the contact page on this site, from an address at the domain, and the report will be taken down. It only ever shows what the domain already serves publicly.
