Your brand is a lot more than just a name or a logo. It's the feeling that someone gets when they come into contact, any contact, with your organization. In fact, the thing that really increases engagement and drives loyalty isn't your products or services (though, to be fair, they do help quite a bit) - it's this idea of the larger brand itself.
Because someone could potentially have that experience with your brand, the idea of brand continuity could not be more important. Regardless of how someone interacts with your brand, it should all feel like it's naturally coming from the same place at all times. To truly master the idea of using continuity to strengthen your branding efforts, there are a few key things you'll need to keep in mind.
One Brand, One Voice - No Exceptions
Continuity means all of your marketing efforts need to feel as consistent as possible regardless of what those efforts happen to be. In the world of print marketing, this can be as simple as making sure that all of the fonts in your advertisements match (or at least reflect) the fonts on your actual products themselves. This can also encompass larger ideas, like if you revamp or redesign your company logo in one place you immediately roll it out everywhere at the same time to avoid confusion.
In a single word, your goal is "synchronicity." Every marketing-related decision you make must serve two masters. First, it must be purpose-driven with a strategic move made with a specific payoff in mind. Secondly, you need to make sure that it is NOT a move that is ultimately at odds with the way you talk to customers, the relationship that you have with them, or the idea that they have of your brand to begin with.
A Great Persona Makes All the Difference
Brand personas are incredibly helpful in this regard because they allow you to laser-focus your messaging on a few of your "ideal" customers in a way that makes it much easier to maintain one voice. If you segment your target audience into groups that are each represented by a singular fictional persona, it makes it much easier to make consistent decisions across all of your efforts. You can both make sure that continuity is preserved for all materials targeted at those people, but you can also easily get a "bigger picture" look about how each individual effort plays off of and compliments the rest.
The impact of negative brand continuity isn't limited to a customer getting their wire's crossed. Eventually, this problem will create a challenge that is much harder to overcome - a total loss of brand value in general. Not only will this see fewer sales for your actual products and services, but the same will be true of any retailers that may sell your products as well. This, in turn, will create fractured relationships, which goes a long way towards putting you farther away from your goals, not closer to them.
