RECOMMENDATIONS
1. Integrate comprehensively
Use all senses. Visual cues are important, and memorable characters differentiate, but audio cues like consistent voiceovers and music also help. Consumers will not notice all brand integration cues, so test to see if your campaign fits together.
2. Start with a strong campaign idea
Start with a killer, insight-fueled campaign idea and develop tightly integrated executions that work together to bring the idea to life. Build out from the core, don’t work back from a TV ad.
3. Make each piece of content amazing
Individual creative quality defines overall campaign success. Do your idea justice by testing executions for all major channels.
4. Invest only in channels that have a clear role
There is little benefit to more channels unless they have a clear role in the campaign, and in reaching your audience. In the online space, target judiciously and don’t intrude.
5. Customise content for each channel
Only develop content for channels where you can adapt excellently and make the most of the format. Find a balance between integration and customisation. A great campaign needs enough familiarity to tie campaign elements together, but enough novelty to engage with complementary content.
