The Same Owner Websites tool allows you to uncover hidden connections between different domains by searching for shared tracking codes, ad network tags, and analytics identifiers. It quickly scans public web data to reveal other properties utilizing the exact same tracking or monetization setup.
What is it
The Same Owner Websites tool is a reverse-lookup utility designed to analyze tracking IDs embedded within website source code. When you run a query, the tool searches public databases for matching strings corresponding to popular web platforms. These platforms include Google Analytics (UA and G-4 property IDs), Google Tag Manager (GTM containers), Google AdSense (pub-publisher IDs), and Facebook Pixels.
Website owners often use identical tracking codes across multiple distinct domains to manage traffic, run marketing campaigns, or monetize content from a single dashboard. While this is a standard administrative practice, it creates a unique digital fingerprint. This utility leverages those fingerprints to map out networks of sites operated by the same individual, business, or organization, even when the domain registration details are hidden behind privacy services.
Why it matters
Understanding the network of sites connected to a specific tracking ID is critical for competitive intelligence, security analysis, and search engine optimization. If you are conducting due diligence on a potential business acquisition or link-building partner, knowing what other sites they own helps you assess their overall digital footprint and authority.
From a security and privacy perspective, exposed tracking IDs can inadvertently link anonymous blogs, portfolio sites, or niche affiliate pages to a corporate entity or personal identity. Threat actors and investigators frequently use these connections to map phishing networks or spam operations. For website owners, auditing your own domains with this tool ensures you are not leaking proprietary ownership data or leaving abandoned sites connected to active corporate accounts.
How to use this tool
- Navigate to the Same Owner Websites tool page on XiaTools.
- Locate the search input box in the center of the screen.
- Enter a valid tracking ID (such as a Google Analytics ID or AdSense publisher ID) or a domain name into the box.
- Click the Check button to initiate the lookup process.
- Review the generated list of associated websites displayed in the results table below.
How to read the results
The results interface provides a comprehensive breakdown of the domains associated with your query, categorized by the specific tracking platform detected. For example, if you analyze example.com, the tool might return a primary table showing all domains sharing the Google Analytics property UA-12345678-1 or G-4 measurement ID G-ABC123XYZ.
The output typically includes the discovered domain name, the type of tracking ID matched, the date the connection was first indexed, and the status of the target site. A realistic output for a shared Google AdSense publisher ID pub-9876543210987654 might list example.com, example-shop.net, and example-blog.org. This indicates that all three properties are monetized through the exact same advertising account, pointing toward a single operational entity.
Common problems and how to fix them
No results found for a known tracking ID
If you enter a tracking ID that you know is active on multiple sites but receive no matches, the databases may not have indexed the secondary sites yet. Search engines and web scrapers rely on continuous crawling to map source code. To fix this, ensure your sites are public, accessible, and not blocking automated crawlers via your robots.txt file.

Too many unrelated results
Generic tracking IDs or default template codes can sometimes return massive lists of unrelated websites, particularly with shared Google Tag Manager containers or free platform templates. If your results are cluttered, narrow down your search by targeting a unique platform ID, such as a specific Google AdSense publisher ID rather than a generic analytics script.
Dynamic or asynchronous loading issues
If a website injects tracking IDs dynamically using complex JavaScript frameworks after the initial page load, basic scanners might miss the identifier. Ensure your critical tracking scripts are hardcoded directly into the initial HTML document header if you want them to be reliably indexed by discovery tools.
Best practices
Always maintain strict separation of tracking and monetization accounts across distinct business ventures to protect your operational privacy. Avoid reusing Google Analytics or AdSense IDs on personal projects and client sites, as this creates an unnecessary web of interconnected assets. Regularly audit your own domains using this tool to verify that legacy websites, staging servers, and abandoned projects do not expose your primary business tracking identifiers to the public.
