How redirection is effectively works?

Hello!

I have done mistake by writing 2 posts on same topic.

Now I want to change the article but it will take so much time to reoptimze it change the content to make similar to the intent.

Now, I want to redirect the low search volume to high one.

How to do this manually ?

Actually I don’t want to add more plugins to my site as it slow the site speed.

Thank you so much.

I thing I haven’t cleared the topic yet. You can check the speed of my sports site by your self.
