Google updated its page rank algorithm in December 2013 and will continue to do so every 3-6 months. The page rank update checks websites and their inbound links to ensure they follow Google's guidelines. If a site sees a decline in page rank after an update, owners should analyze the site to ensure high quality, unique content, proper on-page design, an effective social media strategy, links from high-quality sites, good link building, and avoid spammy techniques in order to improve rankings.
