Where is alison.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 alison.com running on?
alison.com exposes 3 identifiable technologies: Google Analytics, Google Tag Manager, Cloudflare.
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.
Visitor tracking is present (Google Analytics and Google Tag Manager), so this homepage is not cookie-free.
- Google Analytics
- Google Tag Manager
- Cloudflare
How does the homepage respond?
The server answered with HTTP 200 over
HTTPS.
At 404ms to first byte this response is unremarkable for a homepage measured from a single European location.

What does the homepage say about itself?
The title is 46 characters, inside the range that displays without truncation.
A meta description of 159 characters is present.
There are 2 H1 headings. One is conventional; several dilute the signal about what the page is primarily about.
8 of 73 images carry no alt attribute, which leaves them unreadable to screen readers and uninterpretable to image search.

Does alison.com settle on one address?

The www address redirects to https://alison.com/, so the site settles on one canonical hostname.
How easily can alison.com be crawled?

A deliberately invalid URL correctly returns HTTP 404, so missing pages will not be indexed.

No consent management platform was detected alongside them. Where GDPR or the ePrivacy Directive applies, analytics and advertising scripts generally need consent before they load.

How are images, fonts and scripts handled?
73 images on the homepage, 0 of them lazy-loaded (0%).
All image references use JPEG, PNG or GIF. WebP or AVIF typically cut image weight substantially at the same visual quality.
Fonts are loaded from Google Fonts, which means every page view also contacts Google. Self-hosting removes that dependency.
The page pulls 7 external stylesheets and 15 external scripts, with 9 carrying defer or async.
Responses carry Cloudflare edge headers, so content is served from a CDN rather than straight from the origin.
Is alison.com accessible and current?
The page uses 3 landmark elements and 3 ARIA attributes.
There are 20 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.

Nothing on the homepage prevents indexing: no noindex is set in the robots meta tag or the X-Robots-Tag header.
The homepage carries 159 internal and 20 external links across 10 outside hosts.
Visible text is only 4.3% of the HTML, which indicates the page is assembled in the browser rather than served as content.
The heading outline skips 2 levels, which breaks the document structure screen readers navigate by.

The HTML is served with Cache-Control: no-cache, private.
A web app manifest is declared, so the site is installable as a progressive web app.
