Need some SEO advice - I am planning to shift one of my websites which catered to a global audience to a country specific audience. Now that website is pretty old and some of the posts have been linked from high-ranking websites. I dont want to loose out on the backlinks and at the same time I dont want those posts because those stories are irrelevant for my new demographic. I was thinking of redirecting those posts (301) to my new sitemap. Is that a good idea? my aim is to remove the posts and not loose the backlinks for good.
