Keyword Planner is a free tool that can be accessed via Google’s AdWords. The tool is built to help advertisers search for keywords that they may wish to target in their campaigns. Keyword Planner also includes historical data on the use and volume of that keyword in searches, which can help marketers know when the right time might be to engage with the keyword or words.
It’s important to bear in mind that Google AdWords has different functionalities depending on the amount of money spent on the service. For example, high-spending advertisers are provided with the specific figure for average monthly search volume, whereas lower spendings are presented with a range – for example, 1K-10K.
