Think both quantitative and qualitative when it comes to presentation format--so use Excel for the numbers, but also include a Word document or slideshow deck to flesh out the granular data. "The nice part is the ability to take a complex spreadsheet and create very easy-to-read charts with trend lines from them," Jahn says. "Including charts like these within a Word document can provide the trusted information that large company decision-makers seek."
Also keep in mind that you may be presenting to multiple levels of management, with varying degrees of awareness of the intricacies of search. So you may need to develop separate presentations and prep for more than one meeting.
