After the match, Naismith admitted the visitors were slightly sluggish at Craven Cottage but felt the excellent form they have produced this season helped get them over the line to move within four points of fourth-placed Arsenal.
"It was a big win especially at this stage of the season. You'd probably take results over performances, but today we were probably a bit lethargic in the first half but it shows the quality we've got amongst us," the Scotland international told Sky Sports.
"We stuck in and by the end of it we were controlling the game.
"(The manager Roberto Martinez) wanted us to be a bit lively going forward and there was a lot of space to make things happen and that's what I was trying to do.
"Looking at the first goal, the ball came to me on the edge of the box and I was just trying to get it on target and the last one for me was trying to seal the win and take some pressure off at the end of the game."
Of Everton's current position, Naismith added: "This time of the season you're pushing for Europe and the wins are vital so you need to get them."
