The Google Keyword Tool is a staple for anyone running an Adwords campaign. Also helpful as a keyword research tool, the Keyword Tool allows you to find related keywords, which can subsequently be targeted through your campaigns. The tool presents suggested keywords, along with search volumes, competitiveness, average CPC (cost per click) and a range of other customisable data points. You can then feed the keywords you discover directly into ad groups within your Adwords interface.
