Simply click on the graph for the month of Feb 2015 (MayPac announcement month) and it will state 10 (the percent of the maximum month on the graph, which is the month of the MayPac fight). For this current month, MayMac will register an 18 for this month so far. Sooo, 18/10 equals 1.8 times more internet searches for the key words "Floyd Conor" than "Floyd manny".
Obviously, this isn't comprehensive but it sure beats people pulling shit out of their ass and calling it gold, which is what the people stating that the MayPac announcement was bigger have been doing.
I think next month will be a better judge of interest though. I don't know how up to date the results for this month are for example. Also, it could also be an indication of people being like "who the fuck is Conor". However, why they would put Floyd in that search is beyond me.
