We are looking at creating Categories in Content AI (Predictive Content). I know every business is different, but does anyone have good recommendations for categories? Do you have any feedback on a good strategy for selecting categories? For example, is it better to stick to content types like Blog and Video or to create categories like B2B/B2C, [description] Industry, or [description] product.
From what I understand, you cannot say that a content piece is part of Category A AND Category B (only part of Category A OR Category B), so I'm thinking it's best to keep this simple.
I use categories to group similar content, whether that is type or theme; you can tag something multiple times, it just comes down to how you call it on your site or email -- so, for example, I would create tags for all 'webinars' then tags for themes like 'best practices' -- then when I implement the tag on the site, if that page is specific to webinars, I use the content tag; but if it's something specific to 'best practices' then I use that tag and allow any content type to show up. I tend to over-tag for this reason, and if you ever needed a 'double-tag' scenario you could create a tag that has both types as well. So you could have a "Best Practices - Webinar" tag if you wanted to use both. At that point the use-case becomes pretty open-ended, but I like to keep the end user in mind and keep the content as relevant as possible.
It's purposefully open to create any category, so flexible to accommodate many options. The best cases I have seen are for product, solution types, Content resource types (like blog, video, PR), language (English, Spanish), Stage of Funnel (Top, Middle, Bottom).
Hope this helps!
