Open your Google Search Console property, click Settings in the left sidebar, then select Users and permissions. Click the Add user button in the top right, enter the person's Google account email address (typically a Gmail or Google Workspace email), and choose their permission level: Owner for full control including user management, Full for viewing all data and some actions, or Restricted for view-only access to most reports. Click Add, and they'll receive an email notification with immediate access. Permission levels matter. Owner grants complete control, including the ability to add or remove other users and delete the property. Full users can see all reports, submit sitemaps, manage URL parameters, and use most tools except user management. Restricted users can view most data but can't take actions like submitting sitemaps or requesting indexing. For agencies like Ottawa SEO, we typically request Full access for day-to-day optimization work, while clients retain Owner status. You can share access to individual properties or entire domain properties. If you verified your site at the domain level (using DNS verification), anyone you add gains access to all subdomains and protocols under that domain. Property-level verification limits access to just that specific URL version. Most clients share access to the primary property they're monitoring, typically the https://www version. Common mistakes include sharing access to only one property version when multiple exist, or forgetting that the person needs a Google account first. If they don't have one, they'll need to create a free Gmail account before you can grant access. Access changes take effect immediately, though it can take 5-10 minutes for the invitation email to arrive. You can revoke access anytime through the same Users and permissions menu by clicking the three dots next to their name and selecting Remove access.
