Unlike a weak phone signal solely causing a grainy sound, in growth marketing, it can mean the difference between a successful program or a massive cash bleed. As we move toward an increasingly privacy-centric world, it is even more necessary for companies to nail down signal early on.So what exactly is “signal” in growth marketing? It can carry many different meanings, but holistically speaking, it’s the event data in our arsenal to help guide decisions. When it comes to paid acquisition, it’s vital to optimize and pass back the correct event data to paid channels. This is so that targeting and bidding algorithms have the most enriched data to utilize. I’ve seen startups spend thousands of dollars inefficiently as a result of not having optimal signal in their paid acquisition campaigns. I’ve also spent millions at companies such as Postmates refining our signal to the best possible state. I’d like every startup to avoid the painful mistake of not having this set up correctly, instead making the most of every important ad dollar.
