Quality backlinks from blog networks needed for Spanish site
I need 1 way backlinks from blog networks or simply from 300-400 articles. Articles posted must be unique or spinned in English, but the anchor text and backlinks will be in Spanish.
Let me know how many blog networks you have account (or you won your blog network)
They accept Spanish links with Spanish keyword anchor
Price for 50 backlinks (I know you have no work since it’s a matter of publishing the article in blog network)
I will pay only after verify the links and google indexing of the same. (you are responsible for make all the links index by google) More works will be given if this works fine.
