I have just spent some time tidying up categories and tags on the site. The site was first started in January 2008, I know this as I left the first post that WordPress created on installation. That was like cleaning up and finding something that you have bought and forgotten about.
I have to confess that I have found the ideas that lurk behind tags and categories. I am slowly getting to grips with it. This post was prompted by an article on WPbeginner.com called “How to Merge and Bulk Edit Categories and Tags in WordPress”.
This article was useful and a plugin mentioned in the article allows bulk handling of categories and tags. Useful when conducting a de-cluttering of you site and a great time saver as well. I can also recommend another post on the WPbeginner.com site Categories vs Tags. Better still subscribe if you are a new WordPress User
