Year-end lists of the top searches provide a snapshot of what people look for on the internet and how they use search engines. Such lists also provide an overview of the topics, events, issues and people that were most culturally relevant that year. For marketers, the top searches don't necessarily represent keywords to be focused on; instead, they help keep SEOs informed about search trends, audience tendencies and where - or where not - to be focusing their efforts. Year-end lists have been released by Google, Yahoo, Facebook and Bing. While these sites vary in traffic, they're all still in the Alexa top 25.
