For example: my blog article about 'class management' doesnt get ranked at all on 'class management', so I want to change the focus keyword to 'how to get my students to be silent'.
There are 2 options for this. Which one is the best?
Is it better to...
A) Cut the text from the blog article, then delete that blog article and paste the text into a new article in which you focus on optimizing for the new keyword?
-> Advantage: New blog posts get a boost from Google: a fresh start.
Or is it better to...
B) Keep the article and just update it so that it focusses on the new focus keyword?
-> Advantage: updating a blog post is a ranking factor.
Thank you in advance!
