What I usually do is try to make the increase in the stitch that would come next. If the row ends in a knit and I have to increase, I'd knit, purl into the last stitch, for example. It's not perfect, but as you incorporate the increases into the overall pattern, it looks like the stitches blend out from the seam and look fine.
