How do I use the Keyword Tool?
You can access the Keyword Tool from within your ad group to get results based on your existing campaign settings and your account's performance history. Alternatively, you can access a standalone Keyword Tool from within your AdWords account that will not consider either of these factors. If you do not have an account or do not wish to sign in to your account, you can use our external Keyword Tool at https://adwords.google.com/select/KeywordToolExternal.
To access the Keyword Tool from within your ad group:
1. Sign in to your AdWords account at https://adwords.google.com.
2. Select the appropriate campaign and ad group.
3. Select the Keywords tab.
4. Click Keyword Tool.
