I intended to sell some text links spaces( for revelant sites only ) in my homepage to cover other ads for my site. But someone told me that by selling it will hurt my ranking instantly??? I am confused what would be happened then? another warning was If I sell more than 20 text links in my page, I also risk to loose my pr too.
Please advise me as I think I am not gonna sell anything if it harm to my ranking.
Thank you for your advises in advance!
