Newcastle made it four wins on the trot after overcoming West Brom 2-1, Moussa Sissoko's thunderbolt sealing the victory in the 57th minute, four minutes after Chris Brunt had cancelled out Yoan Gouffran's first-half opener.
Ameobi, who lined up alongside Loic Remy in attack, said after the win: "It's been a fantastic November for us.
"A lot has been made of our consistency and I think we've proved we're a side that can bring it week in week out, and that was a tough game for us but we've grinded it out and we're all delighted."
Asked what the difference has been, Ameobi told Sky Sports 1: "I think there's a togetherness in the squad.
"Obviously if you're going to win games everybody has to pull in the right direction and we've got a system here that we've all bought into and it's working for us and we're delighted we're able to give our fans that sort of victory.
"Maybe last season when they equalised we wouldn't have gone on to win that game. It shows how motivated we've been and we're just loving every minute."
Newcastle moved on to 23 points with the victory, one behind the three teams immediately above them - Liverpool, Chelsea and Everton.
With the likes of Manchester United, Manchester City and Tottenham below them, Newcastle can feel rightly proud of their achievements.
However, Ameobi insisted they will remain grounded.
"Winning four in a row will shoot you up the table but we're not getting carried away," he said.
"We'll enjoy this one tonight, being fifth in the table is fantastic. We've got a quick game coming up on Wednesday (against Swansea) that we've got to get ready for and we're looking forward to that."
