Creating Global Views
You can create a Global View that will combine all your URLs with all the keywords and show you the overall aggregated statistic.
To create Global View, just click: '+ Create View' in the bottom of your sidebar and you will be taken to the dashboard where you can save the View and access it whenever you need it.
You can create Global Views for specific keywords taken from different URLs, only specific URLs, and much more. You can apply criteria depending on what you would like to achieve.
