Generally speaking when attempting to count online blackjack you are looking for some form of speed blackjack and/or playing at least 3 tables at once, preferably more. That is the point from an AP perspective.
If you can't or don't want to do that don't play.
Close any table where the count goes south early and load a new one.
Mostly the online casinos believe their crappy rules protect them from counters so they usually leave you alone. There will be some kind of win amount trigger however.
