The Dons are currently stuck in mid-table, eight points adrift of the play-off spots and six above the relegation zone, following Saturday's battling 1-1 draw at Burton.
And Ardley wants to ensure they are looking up the table rather than over their shoulders during the final nine games.
"All the teams are under pressure from top to bottom in this league, whether that's going for the play-offs, the top three, or fighting to stay away from the bottom," said Ardley.
"It's incredibly tight and the fans and players have to come together as a club and give everything during the last nine games.
"The fans here are brilliant when they're on song and let's hope we get that in the last nine games."
