Following white hat seo technique for my own website (Discounts Gyan) its a portal website. From last 4 month doing seo & smo for both keywords (Packers and Movers / Movers and Packers). But at yet did't stable rank on google. Another page's keywords are stable on google. But only packers and movers related keywords sowing fluctuation daily. So pleas suggest me how can stable these keywords.
