I made a huge mistake. Last week I changed the structure of my website. I had a directory that looked like mysite.com/episodes/voyager/file.html
Well I went from just doing star trek reviews to doing movie reviews as well, so I changed directories around and now all those links on google are dead. the links would now be mysite.com/main_docs/trek/episodes/voyager/file.html
Well this really bothers me because I had no idea how over the past 4 months my site really began to catch on to search terms. Like, if you type in "Voyager Prime Factors Review" my site is number 6 on google. But again, the link is now dead.
So I'm not sure the best way to handle this. Should I change my 404 document to say "this page has moved, click here" so that people can get to the proper page. Should I do some sort of automatic redirect? should I put a message asking people to click to the home page?
I'm just not sure what to do, or how to change a 404 message. I had always thought 404 page not found message was client side; not server side, yet I have in my main directory of my site, a file called something like https_404.html
