If the search query is processed, in the right side panel inside of Frase there's the SERP tab where you first may see 'People Also Ask' (PAA) questions at the top that you can paste into the editor.
Below the PAA questions, but above the header strucures and content of the top search results, are a few key buttons:
1. Generate content brief button (circled in red below): Automate a content brief as described here.
2. SERP metrics button (circled in blue below): Provides a bar graph of important metrics per search results (along with min, max and average across all results) that can be exported to a CSV or Excel file.
3. Customize results button (circled in green below): Deselect certain search results you do not wish to include and import pages you want to include.
Any content from the sources can be cited quickly by clicking the header of a source, and clicking the paste button next to the text you wish to add. The text will be added to the editor with a link citing its source.
