Updating your content regularly is important, for search engines and readers. Search engines favor posts that are more recent and relevant because that is what their users want. You want to minimise dupe content, rather than block it, I find the best solution to handling a problem is on a case by case basis. If users consistently ditch your site, it’s a sign the content doesn’t match up to their expectations. In evaluating the worth of these inbound links, some search engines consider the rank of the website providing the link to your website. By simplifying on-page content and a website's architecture, users will have a more positive and meaningful experience navigating your website.
