Hello, everybody! I read that is better to have the url like www.example.com/white-shoes.html then www.example.com/white_shoes.html. But i found this to late and my site is already on server. Can someone tell me please how can i change this without to have erors 404. I deleted 2 files from my site and now, all the time google webmaster tools send my messages that i have 2 erors 404 to those files i've deleted. The site is www.hoteluri-in-bulgaria.ro. I'm a beginer and please give me an advice but with more details to can understand. Thank you!
