A company may need to create more than one buyer persona for several good reasons, nevertheless, do not forget that the whole point of creating a target persona is to narrow down your marketing focus. For this reason, you should be cautious not to create too many.
If you happen to arrive at more than three buyer personas, it may be best to decide on which two or three are the most valuable to your business, and focus on them. According to the late Peter Drucker, an expert management consultant and educator, the key to all economic success lies in concentration. What this means is that it is always more profitable to do right by only two or three targets than to share your effort to serve many.
One helpful way to reduce the number of target personas for your marketing scheme is to group them according to needs. That way, you would arrive at fewer groups thereby narrowing your target focus. Although it is better to have a few targets, preferably not more than three, there are times where having multiple target personas is essential.
