I have a custom CMS for the performing arts center in my town about to launch. They will have artists/events/media, etc. on the site via the interface I’ve built for them in php/mysql.
My question has to do with google indexing and the CMS content. Odds are they won’t be deleting archived shows (which will have a url like so: calendar_expanded?id=310) but if they do, the page will display a little blurb telling the person trying to access that record that it no longer exists, or never did.
What kinds of things should I worry about when it comes to SEO and the file calendar_expanded.php and how google and other search engines index it?
Thanks in advance,
jay.
Edit
What I’m getting at here is that I don’t want search engines getting a 404 error returned from the site. If the page is suddenly unavailable with REST-ful URLs as folks are suggesting I’d have to implement some way for a .htaccess permanent redirect, no?
Make sure that you send the appropriate HTTP status codes to tell the clients the status of their request. If a requested resource can not be found or does not exist, send the status code 400; and if it does not exist any more, send the status code 410 if possible.
