On my MNS I already have a post (WP platform) ranking for a certain KW. The article was shitty and short so I decided to write a new one for the same KW. I saw in that case two options: 1. Delete the text of that shitty article and insert the new one (=substitute content). In this case I am keeping the same URL and all the backlinks to it. 2. Publish new article as a new separate post using the same KW in meta tags, then 301 redirect the old post to this one to pass the juice. I went with the second option, but now I am having doubts if it was the better one. What are your thoughts on this?
