How to change category and tag base name in wordpress?
Instead of using "category" and "tag" in your permalinks you can change them to any name based on your blog theme, you can include keywords like
http://example.org/category/uncategorized/
to http://example.org/categorychanged/uncategorized/
http://example.org/tag/name
to http://example.org/tagchanged/name
After you login to wordpress dashboard: navigate to permalinks under settings section. Give your category base and tag base a name (keyword) and save it... your blog will now be powered with more relevant keywords which helps in search engines understanding your blog.
