They grabbed all three points to ease themselves out of the League Two drop zone thanks to French sub Kevin Sainte-Luce's late goal in a 1-0 victory.
Ardley said: "I thought we played really well throughout the game. We created two or three good chances in the first half, while at the other end we were hardly troubled.
"In the second half we defended setpieces well, we put our bodies on the line and in the end we've managed to secure a great three points.
"Everyone can see we're so much fitter and stronger now, there's a real belief amongst the players.
"We've got that momentum now, and to be honest I always felt we were capable of getting something here.
"We can't get too carried away though. There's still another five more wins to go and this league can be very unforgiving.
"We've just got to keep going and keep trying to get those wins, hopefully well before the end of the season."
