I am going to build more than 50 (maybe 300) blogs with different C-Classes. i will interlink them and post articles daily and add links on the articles. now i have some questions and hope you will help me. 1. Do i need 50 domains for the 50 C-Class IPs? is there any problem if i used subdomains? ( i mean problems with google and SEO) 2. Suggest me a good and cheap provider for C-Class hosting. 3. I didn't use C-Class hosting before, so i don't know what i will need, plz let me know if there are some important things that should i know.
