Keane has managed just the one goal in 59 games for the Blues.
"I know I should be scoring more. It's something I've always done in the past," the 26-year-old told the Daily Mail, having netted more regularly for Leicester, Blackburn and Burnley earlier in his career.
"I've not been prolific in the last year or so but I need to keep making the right runs.
"We have people at Everton who have got great deliveries. Hopefully I can put a few chances away before the end of the season."
