We present results of optical long-term variability campaigns (10 - 20 years) of the two Seyfert galaxies NGC 7603 and Mrk 110. The variations of the continuum, of the individual broad line intensities and of their line profiles are investigated in detail and compared to line profile variations in NGC 5548 and NGC 4593. Individual emission line profiles vary differently from line to line and from outburst to outburst indicating a complex and structured broad emission line region.
