Keyword Manager allows you to create an unlimited number of keyword lists for all paid subscriptions; and users with a paid account can give ______ access to any free user.

Keyword Manager allows paid users to share their keyword lists with free users, but only with "Viewer" access. This means free users can see and analyze the keywords in the list, but they cannot make any changes, add new keywords, or delete existing ones. "Editor" access would imply the ability to modify the list, which is restricted to paid accounts. "Owner" access would grant full control, including deletion and transfer of ownership, which is also not available for free users. This tiered access ensures that core functionalities requiring a paid subscription remain exclusive while still allowing for collaboration and sharing of research insights.
