If I get links from blogspot or wordpress blog which is free and not a domain so will I get value for those subdomain link? Please let me know. In this way any one can make 1000 of blogs and out their own links. so does google give value for this link? waiting for your reply.
Yes. There is a value for each and every blog links. But the blog should have high quality original content to be counted. If you create 1000 blogs with no info in it and if you link it, there is no use.
Better off building one or two really good blogs and sending quality links from relevant pages than building 1000 spam blogs. Google has seen that one before.
