hi i will make a site like this : http://www.zobad.net just i will put youtube videos and write some reviews but i will get many visitors so can i use a shared host for this site with large number of visitors? and what is the maximum number of visitors then should i buy vps or ded server ? thanks
As long as the videos are hosted on Youtube, they aren't going to exhaust any of your server resources. If you were hosting them on your server, then yes, you would need a good amount of bandwidth/transfer.
Don't be worry. Get started from shared hosting, when its traffic become higher and out-of-control, your provider will notice you about upgrading to better solution like VPS.
except you upload for multimedia for streaming under your site thn you would required a better bandwidth and dat is what i meant a resources from VPS at least.
