Auditing Google Search Console for unauthorized user access is the process of reviewing the list of verified owners and permitted users to ensure only trusted individuals have control over your site’s search data. This security check involves checking the ‘Users and permissions’ menu and the ‘Ownership verification’ settings to detect unfamiliar email addresses. Regular audits help prevent malicious actors from submitting harmful sitemaps, masking security alerts, or utilizing your site’s authority for spam campaigns.
Why is checking for unauthorized GSC users a security priority?
Google Search Console provides deep access to how your website interacts with search engines. If a malicious actor gains access, they can see your top-performing keywords, crawl errors, and manual actions. They might also use this access to hide their activities, such as injecting spammy content that you might not see on the frontend of your site.
Unauthorized users often use this platform to monitor the success of SEO spam hacks. By looking at the performance reports, they can see which of their injected pages are ranking and adjust their tactics. This makes the breach harder to detect through standard traffic monitoring alone.
SEO spam hacks occur when malicious actors gain unauthorized access to your website infrastructure to inject unwanted content, hidden links, or redirect scripts into your pages.

How to identify suspicious property owners in Search Console?
To begin your audit, navigate to the Settings menu in the sidebar of your Google Search Console property. Click on ‘Users and permissions’ to see a list of everyone who can view or manage the data. You should look for any email address that does not end in your company domain or belong to a known agency partner.
Some attackers verify themselves as ‘Owners’ rather than just ‘Full’ or ‘Restricted’ users. Click on ‘Ownership verification’ under the settings tab to see the specific method used for each owner. If you see an HTML file or a DNS record that your IT team did not create, it is a clear sign of a security breach.
Common signs of unauthorized access
- Email addresses from generic providers like gmail.com or outlook.com that no one on your team recognizes.
- A sudden increase in the number of verified owners without a corresponding internal project.
- HTML verification files found in the root directory of your server that were not placed by your developers.
- New DNS TXT records in your domain registrar that link to unknown Google accounts.
- Meta tags added to the header of your website that you did not authorize.
What are the risks of ignoring unauthorized access?
Ignoring an unknown user in your console can lead to catastrophic losses in organic traffic. Attackers can use the ‘Removals’ tool to temporarily hide your most important pages from search results. This can happen quickly and might go unnoticed for days if you are not checking the console daily.
Furthermore, unauthorized owners can ignore security warnings sent by Google. If your site is flagged for malware, the attacker might see the notification and delete it or simply ignore it, leaving your visitors at risk. This leads to your site being marked as ‘Deceptive’ in browsers like Chrome.
Malware is any software or mobile application specifically designed to harm a computer, a mobile device, the software it’s running, or its users.

How Alien Road applies search console security audits
Alien Road includes a security layer in every SEO engagement. When we start a typical project for a client, such as a Shopify store or a custom B2B platform, the first step is a user audit. We do not just look at who is there; we document every active verification token found on the server and the DNS.
If we find an unauthorized user, our team works with the client’s developers to remove the source of verification first. Simply deleting the user from the Google Search Console UI is not enough because the attacker can re-verify their status if the HTML file or DNS record remains active. We provide a clear report of when the access was likely gained and what data might have been compromised during that period.
Step-by-step process for removing malicious owners
Removing an unauthorized owner requires a specific order of operations. If you remove the user first but leave the verification token, they will reappear in the list within hours. Follow these steps to ensure the removal is permanent and secure.
- Identify the verification method: Go to Settings > Ownership verification to see if they used an HTML file, meta tag, or DNS record.
- Remove the token: Log into your server, CMS (like WordPress or Shopify), or DNS provider and delete the specific file or record.
- Unverify the user: Go back to the Search Console settings and click ‘Unverify’ next to the suspicious user’s name.
- Change your passwords: Treat this as a full site breach. Update passwords for your CMS, hosting account, and your own Google account.
- Audit other properties: Check if the same user has gained access to your Google Analytics or Google Ads accounts.
Common methods attackers use to gain property access
Attackers often gain access through vulnerabilities in your website’s software. Outdated plugins or weak server passwords allow them to upload a small HTML file to your root directory. Once that file is live, they can go to Google Search Console and claim ownership of your domain instantly.
Another common method is through compromised personal accounts. If a former employee’s Gmail account is hacked, and that account still has ‘Owner’ status, the hacker gains full control. This is why maintaining a clean user list is a key part of technical SEO maintenance.
Where to start this week
Open your Google Search Console account today and go directly to the ‘Users and permissions’ section under Settings. Export the list of users to a spreadsheet and ask your team to verify every single email address on that list. If you find an address that no one recognizes, do not wait; check the verification method and begin the removal process immediately.
Schedule a recurring calendar invite for the first Monday of every month to repeat this audit. Regular monitoring is the most reliable way to catch SEO spam hacks before they cause permanent damage to your rankings and brand reputation.
