The Dons barely troubled home goalkeeper Ben Williams but stay one point ahead of Hibs in eighth place.
Former St Johnstone and Bristol City boss McInnes is well aware of the task that awaits him next season.
He said: "It was probably a performance and result which shows you where we are at the minute and there is certainly work to be done.
"It ended up being a game of two teams going toe-to-toe and I think both teams deserved their point.
"You always have to take the positive of the clean sheet but we wanted to win the game so you come away only half-pleased.
"I have to credit my players for their appetite for the game.
"But it didn't tell me anything that I didn't already know."
