In general, with HeartCatch as notable exception, viewership declines over the years.

The first season has been seen by the most people by far, but has the lowest rating. HeartCatch, Splash Star and Fresh are rated highest; Dokidoki and Smile have low ratings.

Yes5GoGo has been seen (and rated) by fewer people than Yes5, but gets a higher rating. The same goes for FwPC and Max Heart, illustrating that sequels are rated higher than their preceding seasons because of viewer self-selection.
