Features of this tool include:
- Search for keywords in three ways: Use keywords you enter, your existing high clickthrough rate keywords, or any URL for your search. (The option to generate keywords from a URL is available for a limited number of languages.)
- Keyword performance statistics: See Google's performance statistics for your keyword results. Data includes keyword search volume, search volume trends, and predicted cost and ad position.
- Easy keyword manipulation: Select a few keywords here and there, or add them all at once. Keywords already present in your ad group will be marked so that you don't have to worry about them. You can also download your keyword list as a .csv file.
- More keyword results based on regularly updated statistics: Our advanced search engine technology allows us to provide you with the latest information on potential keywords for your campaigns.
