How long to 301 redirect specific pages?
When I first made my website about a month ago, I made all the pages .htm. But then this week I changed that to .php so I could change the header and footer in a separate file.
I setup a 301 redirect for each page in my .htaccess file. I also changed one page from Promotions to Services and set a 301 redirect for that too.
My question is if I should leave those 301 redirects there forever? Or is there some amount of time that they need and then I can remove them?
