Googles Algorithm Pigeon

Launch date: July 24, 2014 (US); December 22, 2014 (UK, Canada, Australia)
Hazards: Poor on- and off-page SEO

How it works: Pigeon affects those searches in which the user’s location plays an important part. The update created closer ties between the local algorithm and the core algorithm: traditional SEO factors are now used to rank local results.

How to adjust: Invest effort into on- and off-page SEO. The tool’s Content Analysis dashboard will give you a good idea about the aspects of on-page optimization you need to focus on.

A good way to start with off-page SEO is getting listed in relevant business directories. Not only do those act like backlinks, helping your site rank; they rank well in Google themselves.
