I've been redeveloping sites with HTML pages to Wordpress. The old pages obviously still show up in Google SERPs, I need the replacement Wordpress pages to take priority, and for the old ones to drop off.
If example.com/widgets.html is now example.com/widgets, what's the best way to set up a permanent redirect for that specific page? Is this something I do entirely in the .htaccess file? If so, how I would I add the coding to the file so that it redirects, and would I need to delete the old html page after doing so?
