You can fix broken links on your store by setting up redirects.
From the Dashboard, go to the SEO Tools tab and select Broken Links.
Click Create URL redirect to set up your first redirect.
In the broken link field, enter the path after your main domain (for example, /broken-link).
In the new link field, enter the new path (for example, /new-link).
Click Fix Broken Link to complete the setup.
For existing redirects, click Add redirect. You’ll see a list of all your redirects, including the broken path, redirect path, their status, and the option to delete them.
