When was zillow.com registered?

zillow.com was registered on 16 September 2004, which makes it about 22 years old.

A registration this old means the domain has been renewed repeatedly, which costs money every year and is not something abandoned or disposable projects tend to do.

The registrar of record is GoDaddy Corporate Domains, LLC.

Registration runs until 11 November 2028.

The domain carries 4 registry locks, which blocks unauthorised transfer or deletion.

Where is zillow.com hosted?

The first address resolves to infrastructure in Frankfurt am Main, Germany.

The network is operated by AWS CloudFront (GLOBAL) (AS16509 Amazon.com, 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 zillow.com running on?

zillow.com exposes 3 identifiable technologies: Next.js, Google Analytics, Google Tag Manager.

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.

Visitor tracking is present (Google Analytics and Google Tag Manager), so this homepage is not cookie-free.

• Next.js
• Google Analytics
• Google Tag Manager

How does the homepage respond?

The server answered with HTTP 200 over
HTTPS.

At 1046ms to first byte this response is slow for a homepage measured from a single European location.

The HTML weighs 461KB, which is ordinary for a homepage.

The HTML is compressed with gzip.

What does the homepage say about itself?

The title is 56 characters, inside the range that displays without truncation.

A meta description of 154 characters is present.

All 7 images on the homepage have alt attributes.

Is zillow.com served over a valid certificate?

The HTTPS certificate is issued by Amazon and is
valid until 2026-12-31, which is 87 days from the date of this check. It covers
5 hostnames.

• zillow.com
• zillow.ca
• www.zillow.net
• zillow.net
• www.zillow.ca

The certificate has 87 days left to run.

Which security headers does it set?

4 of 6 are set (HSTS, Content Security Policy, X-Content-Type-Options, Referrer-Policy). Absent: X-Frame-Options, Permissions-Policy.

How is DNS configured for zillow.com?

zillow.com resolves to 4 addresses, which indicates load balancing or a CDN rather than a single origin server.

Mail is handled by 1 exchanger.

An SPF record is published, giving receiving servers a rule for which hosts may send as this domain.

Reverse DNS resolves to server-18-245-46-34.fra56.r.cloudfront.net, server-18-245-46-38.fra56.r.cloudfront.net, which usually names the hosting provider.

Who runs DNS and mail for zillow.com?

DNS is operated by Amazon Route 53 rather than self-hosted name servers.

Mail is handled by Google Workspace.

No AAAA records are published, so the site is reachable over IPv4 only.

What else is worth noting about zillow.com?

14 of 14 externally hosted scripts carry no subresource integrity hash. If one of those hosts were compromised, the replacement script would run with full access to the page.

1 email address appears in the homepage markup, where address-harvesting crawlers will find it.

Can zillow.com be spoofed in email?

DMARC is set to quarantine, so mail failing authentication is sent to spam rather than the inbox.

CAA records restrict certificate issuance to 1 named authority (issuewild awstrust.com), so no other CA should be able to issue for this domain.

The zone is not DNSSEC-signed. That is still the norm for most domains, but it means DNS answers cannot be cryptographically verified.

What else does zillow.com publish?

An ads.txt file is published with 15 entries, which means the site sells programmatic advertising and has declared who may resell its inventory.

What does robots.txt allow?

robots.txt is 10,524 bytes and names
18 user-agent groups.

It does not blanket-disallow general crawlers.

AI crawler policy

8 sitemaps are declared in robots.txt, which gives crawlers a direct list of URLs.

Named AI crawlers are explicitly allowed (applebot-extended).

What structured data does the homepage publish?

No JSON-LD or microdata was found on the homepage.

What does zillow.com load from third parties?

The homepage pulls resources from 7 third-party hosts (api.consentjs.datagrail.io, cdn.pubnub.com, delivery.digitalassets.zillowgroup.com, fonts.googleapis.com, photos.zillowstatic.com, s.zillowstatic.com). Each one sees the visitor IP and user agent on every page load.

2 cookies are set before any interaction (zguid, zgsession). 2 lack the Secure flag.

The page links or refers to Facebook, Instagram.

Does zillow.com settle on one address?

Plain HTTP redirects to HTTPS, so visitors who type the bare address still land on the secure version.

Both zillow.com and www.zillow.com answer with 200 and neither redirects to the other. Search engines therefore see two complete copies of the site, and link equity is split between them unless a canonical tag resolves it.

How easily can zillow.com be crawled?

A sitemap index is served at https://mortgageapi.zillow.com/sitemap.xml listing 161 entries.

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

What tracking does zillow.com run?

2 tracking scripts detected: Google Analytics, Google Tag Manager.

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 does zillow.com look when shared?

2 of 5 social preview tags are set. Missing: og:image, og:type, twitter:card.

How are images, fonts and scripts handled?

7 images on the homepage, 2 of them lazy-loaded (29%).

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 2 external stylesheets and 14 external scripts, with 14 carrying defer or async.

Responses carry Amazon CloudFront and edge cache edge headers, so content is served from a CDN rather than straight from the origin.

Is zillow.com accessible and current?

The page uses 4 landmark elements and 107 ARIA attributes.

There are 4 form inputs but only 0 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 2006, 20 years behind the current year, which usually indicates the site is not actively maintained.

Can search engines index zillow.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 308 internal and 20 external links across 17 outside hosts.

Visible text is only 1.8% of the HTML, which indicates the page is assembled in the browser rather than served as content.

The heading outline skips 1 level, which breaks the document structure screen readers navigate by.

How is zillow.com delivered?

The HTML is served with Cache-Control: private, max-age=0, must-revalidate.

A web app manifest is declared, so the site is installable as a progressive web app.

Frequently asked questions

Does zillow.com set the usual HTTP security headers?

It sets 4 of 6. The ones not present are: X-Frame-Options, Permissions-Policy.

Does zillow.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 zillow.com built with?

The homepage exposes these fingerprints: Next.js, Google Analytics, Google Tag Manager. 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 5 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 zillow.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.
