Hello, I'm Binny and I have a small question expect people to help. I have a commercial website is NamChamVn.Com.Vn and I saw a number of forums wrote that "Free Backlink" So the Backlink including "clean" does not? And does it have not been downgraded on google? You go to their website to backlink to see such a fine has not it?
Your question not making any sense to me! If you are talking about backlinks which some of the site providing for free then you can take those if your site is aged. But if your site is new, I suggest you not to take those free backlinks. Instead make some backlinks by yourself through social submission & microblog sites like twitter.
In SEO, giving and getting links should always have good reason why a link should be belong site, with regards to relevancy of the sites..
