Hello, A short description of my website: Promoting homepage with a few keywords + internal pages ( /iphone5, /galaxys4, /htcone ). I'm building only white hat backlinks manually a few per day, no spam at all! Suddenly one of my internal pages after was ranking #2 got nowhere in google (i looked over in all pages), the page wasn't deindexed, all other pages kept the good rankings, the homepage as well. Instead one blog post ( /iphone5-how-cheap-will-it-get-in-time ) is still ranking for my keyword but on 5th page. Any ideas what could have happened? Will it ever come back? Should I continue to build backlinks to that page? Thank you!
