Hy, Today i change my server where my website was hosting from a Windows Server to a Linux server because until now i haven't access to .htaccess file. I want to know if this change (because was changed my ip) will affect all my SEO activities that i have been made until now. I mean if all my work (including here: my content, link exchanges, articles submitting, blog posts, directories and so on) that i have been made until now will be affected by this change. Will be my position in Google from a keyword affected by this change? Also what i want to say is that today i was buying a new domain. Well this domain is having the same ip like my principal website (the website that i was talking about before). Obvious has another ftp details. But what i want to know: is there any problem if you have many websites in the same ip? For example: let's say we have 2 websites on the same ip. We want to promote website_1 for keyword_1 and website_2 for the same keyword_1. Is there any problem if website_1 and website_ are hosted on the same ip? The same question if we want to promote for different keywords. Hope you understand what i mean to say...and sorry if i put silly questions but i don't know very much thing on this part of sites and servers administration. Thanks!
