The defender helped the Toffees come from behind to defeat Burnley at Goodison Park on Monday night.
"I have a target in my head, as I do every year," he told the club's website.
"I know I'm capable of scoring goals, I just need to get in the right positions and make good runs and they'll come.
"Thankfully I've done that tonight and hopefully it can continue."
On the Burnley win, Keane said: "It was a similar game to Southampton [on the opening day of the season]. I think we were disappointing in the first half - they had too much space, we struggled to get to grips with the game a bit but we hung on in there.
"Then we conceded in the second half, but I thought we reacted really well. It's always important when you do concede to try to get that goal as soon as you can.
"I got into a bit of space, I saw it and I knew from training where Andros puts those crosses when he cuts back on to his left foot, so I just got in the right place, it was a great cross and I managed to guide it in to get us back in the game.
"We had a 15-minute spell where I thought we were top class - and I thought we could have actually had more."
