Ask How do you decide whether a marketing channel is worth continuing if results are inconsistent?

[Dominic87]

Inconsistent results can be confusing because a channel might perform well one month and then drop the next, making it hard to know if it is truly working. Looking at results over a longer period, instead of judging by a single month, usually gives a clearer picture. You should also check if the drop came from the channel itself or from something else like a bad offer or bad timing. How do you judge if a channel is really worth keeping?
