I’m not aware of this and if it was, it’s a really bad idea. Duplicating content is not a good idea from an SEO perspective and it will also piss off your users, when they click and see that all you are doing is repeating the same stuff.
Not the same stuff. Say I have 3 different sections to my website and I want to post 3 different types of content in a, b, and c. I want to have the ease of posting, but I want to be able to do that on 3 different sections. For example, a page for dogs, a page for cats, and a page for horses. Idk. But, I want the content to be specific for each section within the same website and I still want to be able to use the post feature.
Or can I get my categories to go to the top bar?
If you’ve created a custom menu (Appearances > Menus) you can add as many categories as you want to your navigation bar.
Ya, doing this now. Would it be a problem when I convert my wordpress site to my domain?
