Sometimes like today one of my articles gets published on EZA and shoots straight to the first page of google. I then build a few backlinks for the article and promote it a bit here and there. Then some times my article just dissapears from google, I can't find it anywhere in the first 20 pages. A few days later it will re appear on google's first or second page. Why is it doing that and will my article stick after the initial roller coaster?
