Hi guys, I have a question about value of links that comme from tumblr blogs that have "noindex" tag on their header. I have many backlinks that come from that kind of blogs (adult blogs from tumblr). The point is, every adult blog from tumblr have "noindex" tag in their header, and, i wonder if the links that come from here have any value! Even, if i check in google my adult blog this appear in first page, first position for some KW, even if this blog contain "noindex" tag. Any advice here?
