# Usefull 404
As I’ve changed CMS from etomite to wordpress, friendly url’s are changed a bit. Essentially shortened URL and removed “.html” from the end.
But what to do with old links? I had two options:
- Create redirects to updated URLs
- Make use of 404 error page
I’ve chosen 2nd option, as it is more elegant and requires a few work – more automation.
So, I was thinking: how can I redirect users comming from old URLs to new ones? And here I thought – if link is old one, I get 404. Here I can get that old link and redirect to a new one. Of course that idea is not new, so I’ve googled a bit and found ready made solution: Adding Search results to Wordpress 404 pages
This is more better than moving automatically, because not all 404’s would be from old links and if someone mistypes address – he/she will get search results.
