Scott Clark: Which links are you talking about - internal links or links to the site from elsewhere?
Dante J Funari: Internal links throughout the site. I know 301 redirects are preferred. Just wondering is it best handled via a plugin, changes to a specific file, etc etc.
Dave Elliott: 301 redirect to a relevant page. If internal also update them within your content
Michael Martinez: For WordPress sites I prefer to handle internal redirects via a plugin, especially if there are a large number of them. For one thing, you`re far less likely to cause a catastrophic error if you mistype a redirect in a plugin`s matrix. Modifying server configuration files is not a task that should be routinely performed, especially by people who don`t know what to do if they make an error.
Dan Sylvester: https://wordpress.org/plugins/redirection/This is what i use. works great with regex has bulk redirects with logs and groups.Just make sure you 301 to a relevant page.
