Produce a spreadsheet with 4 columns like this:
1. SEARCH TERM
2. NUMBER OF GLOBAL MONTHLY SEARCHES
3. NUMBER OF RESULTS
Barack Obama | 3,350,000 | 735,000,000 | people
(the categories, I will give you)
NUMBER OF RESULTS you get from googling the term.
GLOBAL MONTHLY SEARCHES you get from https://adwords.google.com/o/Keywo
Use this as the source:
Get the category from the title. E.g. Actors.
So you understand the concept, eventually there will be a game: Who gets more results?
Barack Obama vs. Kittens
