Hi Friends I'm working for a site whose business is Domain Registration and they put Individual pages for Each TLD's(.com, .in etc) now i planned to change the page name with keywords For example For .com TLD Page i planned to change the page name as .com_domain_Registration .com_domain_Registration or Com_domain_registration From the above two names which one is best is there any problem in dots in page name?
I don't think so you can create page names with dots. Second one is better option and also try to use '-' rather than '_' to differentiate the words in key phrase.
I would suggest you to go for com-domain-registration instead of com_domain_registration. The reason behind using a hyphen (-) rather than underscore (_) is SE treats word1_word2 as word1word2 while word1-word2 is counted for word1, word2 and word1 word2. So com-domain-registration would be seen as com domain registration which is your targeted keyword. On the other hand com_domain_registration would be treated as comdomainregistration, for which there would be less searches ( i suppose).
