How does the feature: Claim a listing work?
With the claim listings feature, listing owners can "Claim" their listings and let the site visitors know the listing has been verified by admin and store owner.
By default, listing owners can claim their listings by submitting an integrate form using the "Claim Listing" link on the listing they would like to claim. This form is handled by one of the integrated forms supported by WP Job Manager - Contact Listing (GravityForms, Ninja Forms, Contact Form 7) and they can fill out any details you require.
Once you (site admin) have confirmed they are the owner of the listing you can reassign the author of the listing in the WordPress dashboard and verify the claim from the backend.
If you would like to automate this processes, you can use our WP Job Manager - Claim Listings plugin. This will allow users to automatically submit the necessary claim data and the admin can simply approve or deny the claim from the backend. With the WP Job Manager - Claim Listings plugin site admins can also charge an additional fee for users to claim their listings.
