It can't be all just increases in salary, but don't ever stop increasing salary. You should have a cost of living adjustment, in line with the BLS regional CPI-U index for the last year, as a minimum, and maybe an extra 1% just on principle.

This bare minimum will keep you from coming across as super-cheap and out of touch / unconcerned with their compensation. Remember most employees can get a bigger raise by switching jobs; your salary increases shouldn't make a point of making that obvious.
