Is it SEO safe to build 5-10 sub-domains for a website? or i will better keep all pages on the same domain name?
google will look at each subdomain as it's own site why wouldn't it be safe? just put unique content on each site and build a few links to those url's and you'll be fine
Well if it will treat it as separated domains, this can change to a dramatical situation ... like 1000 backlinks to one sub-domain name, 300 backlinks to another sub-domain name...
But it will be problem bcz getting 1000 of Bl is not easy. And also in each update many links will be droped. So me suggestion make 1 domain to avoiding the sharing and independent domains
