The Search Term report is really great for looking for new keywords that you might not have thought of before and also for discovering invalid keywords that you can exclude from your campaigns.
Google recently added a new filter called “search term” as one of the filter options in the Search Term report. It’s useful when you want to analyze the huge amount of data gathered and you would like to develop a specific strategy. The example provided by Google was a florist trying to discover the search terms related to “valentine” weeks before it leads to February 14.
