Neither side was able to find the net in a game of few chances, which the Dons ended with 10 men after Mark Reynolds was sent off for a second bookable offence.
Saints boss Danny Lennon said: "It's always a very difficult venue to come to, and to pick up a valued point. We had to fight for the point, and we're disappointed in terms of our opportunities that we didn't snatch all three points."
He added: "I thought the pitch probably won in terms of entertainment today. I think it would have suited two men who played back in the seventies, Tam Craigan and Craig Brown himself!"
Lennon admitted that when Reynolds was sent off, his second booking for handball from a Kenny McLean shot, he initially thought his side had been awarded a penalty.
He said "I didn't see the yellow card go up, so when I saw the red, I thought we had a penalty! I couldn't tell you if it was deliberate or not, but the referee got most of the decisions spot-on today."
Dons boss Brown was frustrated with his side's inability to find the net, as they recorded a blank at home for the seventh time this season. However, he was pleased with the overall performance of his side.
He said: "I'm biased of course, but I think Aberdeen were the better team. We missed one or two chances but having said that, our goalkeeper had an excellent save when St Mirren broke away.
"Our old failing of finding the net was apparent. We didn't score, and that's happened too often at home, of which I'm acutely aware. We tried three up front in (Johnny) Hayes, (Niall) McGinn and (Peter) Pawlett, with two supporting midfield players in (Gavin) Rae and (Stephen) Hughes.
"We had five committed to attack, with the full-backs encouraged to get forward, but it's just not happening for us in front of goal. I think it's unfair to be highly critical of Aberdeen, in view of the effort put in by the players. The commitment, particularly down to 10 men, was there and we continued to take the game to St Mirren even with 10 men."
