Category Based Permalinks with Wordpress
As part of a site overhaul, I moved from date-based permalinks to category-based permalinks. I did this to segment the site by top-level categories, and to improve search engine friendliness. Many people argue that this is a superior permalink structure, but very few point out the downsides.
Broken URLs are the single biggest problem. The initial change isn’t a big deal. I used Dean Lee’s Permalinks Migration plugin to redirect all the old URLs to the appropriate new URLs. Watch out, though: whenever you change a category you will end up with a broken URL that’s the above plug-in does not fix. Also, if you change the name of one of your categories, all of the posts under that category will have changed URLs.
