It's not a matter of picking one platform for digital advertising success. Today's consumers use several apps, devices, and search engines in the process of buying. Someone may find a product on TikTok and then look for reviews on Google and make the purchase when they see a retargeted Instagram ad. However, many companies continue to invest in one platform for all their advertising. This method leaves huge blind spots in the customer journey, and makes people rely on a single algorithm, a single audience system, and a single source of traffic.
