To add a user to Google Search Console, start by navigating to the Users page within your account settings. Click on the 'Add user' button and enter the email address of the new user. You will receive an invitation email from Google to verify their account. Once verified, you can grant them access to your Search Console account by clicking on the 'Add role' dropdown menu and selecting a suitable permission level. For monitoring purposes, it's recommended to assign the 'Property Manager' or 'Audience Manager' role to this user. This will allow them to view data, monitor search queries, and set up alerts for specific metrics such as impressions, clicks, and conversions. To set up alerts, navigate to the 'Settings' page and click on the 'Alerts' tab. Create a new alert by selecting a metric and choosing when you want to receive notifications, such as daily or weekly summaries. This will ensure your team member is informed of any changes in search query activity and can take prompt action accordingly.
