When complete, your buyer personas should outline which channels the target customer prefers to use and what advertisements they tend to engage with. They should also include relevant demographic information.
Although multi-channel campaigning involves targeting customers on multiple platforms, you still need to be selective about which of these are best suited to your campaign.

Of course, if you could campaign on every channel, then you undoubtedly would. However, running an effective multi-channel campaign is costly. With each channel you include in the strategy, you’re investing even more time and money in the campaign. This is because you’ll need to craft a strategy, produce content, and pay for ads or sponsored placement on each channel. You’ll also need to tailor your content for each of your chosen channels so that it appears meaningful and trustworthy.
