I started a blog around 6 months ago on wordpress. The main posts were getting around 3k impressions per month.

All of sudden the whole website got down with a google update. I was disappointed and didn't worked on the domain. Now i want to start that blog again.

I have started writing new content for the same blog posts again. Should I just paste new content on same page or create a new blog post. Also, please suggest about Slug.

Thanks In advance.
