The biggest thing to remember is that whether your CES score is good or not depends on the question and scale used. In our customer effort score survey example above, a high CES means a low-effort experience, but the same score could mean the opposite if a different scale was used.
Determining a universally good customer effort score is tricky because of the different scales and questions. There isn't a one-size-fits-all industry standard.
You're competing against yourself, so focus on how your CES score changes over time. As long as your customer effort score is improving, you're on the right track!
