How to SEO Wordpress permalinks

I mistakenly put an apostrophe in my title (for instance girl's). How can I remove it. I know I need either all in one or platinum plugin, but I don't know how to use it.

I don't want to delete the post and repost it because it might create duplicate pages on google.

 

Just remove the apostrophe in the title and update the post.

 

I don't really want to remove the apostrophe. I want to change the permalink because if I try to copy the permalink, the apostrophe is represented by 99%t%2 (something like this). I believe that is the ASCII code of apostrophe. I want to remove that.

 

Same thing. Just remove the permalink code you don't want included and update the post.

 

Why stress over something so minor? Just fix it and move on. Do a 301 redirect from the old to the new if you are so worried.

 

for permalink setting go wp admin > settings > permalinks .

for settings old slug use 301 or redirection or old slug plugin

 

You can even edit the url of the post in the edit screen
