I have been writing my blog since 2007 and I want to redo my categories – create new categories, delete old categories, and reduce the total number I have – and then go through each post one by one and reassign categories.
I understand how to do this from the Managing Categories info in Support, but what I am not clear on is how adding/deleting/renaming categories will impact on individual post URLs, or search engine links… are there implications I should be aware of? Will I be creating 404s? (I have never created links to musicwork.wordpress.com/categories/… in any of my posts but I suppose someone else may have).
And if there are implications, are there any workarounds? I’m really keen to overhaul my blog – lots of things have changed since I first started writing.
