I am working on a domain namely http://www.backdropsbeautiful.com/ and there we've recently changed the coding structure (a design company did that). Now we are facing two problems, the first one is actually changing the URL structure, permalinks. The second one is critical, the previous website has this page for example www.backdropsbeautiful.com/crequest.php this page is indexed in Google at 3rd page for christmas backdrops and has the related christmas backdrops title two sub issues here, 1) that we need to make this 404 redirected to its new christmas backdrops page 2) the new christmas backdrops page doesn't have this title, I don't know but I guess the titles in the previous site were created dynamically, can you check please and let me know if that's true? Thanks.
