I made a mistake by giving the responsibility of creating blog to a person who didn't knew about how to right good quality posts. The blog posts(Total 12 in numbers) are containing similar content that of my website and in the comment section given the websites links. The Posts are nowhere in the google search and the blog not been updated since last 1 year. Now i want to start in a new way and integrate blog section in my website only. But what should i do with the old blog. Shall i delete the entire blog or remove all the posts.
