Google Keyword Tool

Google offers various free keyword research tools.
The most popular and easiest way to get inspiration on long tail keywords probably is Google Suggest. This term describes the drop-down menu opening when simply typing single letters or words into the search bar. The order of offered terms is determined by using a wide range of information in order to decide which query users most likely want to see. The tool therefore provides important insights on potential keywords.

Google Trends visualizes the development of interest for certain search terms over time. It also displays regional interests and identifies related searches regarding general topics as well as specified queries. As the name implies, this is a handy tool for differentiating between trending topics, buzzwords and current issues at all times.

Google Adwords, conceptualized for campaign planning, offers detailed insight into search volumes. This information is important when it comes to competitor analysis for particular search queries. In this regard, it would be a good idea to double check keywords derived from Google Suggest with the Keyword Planner in order to filter very in-demand search terms with the lowest possible competition.
