Every business possesses a unique relationship between first-time buyer AOV and future value. The relationship dictates exactly how the brand must approach marketing for first-time buyers.
An example: "Brand A" has an AOV of $70 and in the first five years after a first purchase the customer spends $230. You wouldn't be surprised if this company offers free shipping, executes television / radio / billboards, hires expensive influencers, seemingly wastes money. This business "can" waste money because the customer pays the brand back over time. In fact, it is almost good that the brand wastes money, because the long-term payback of finding new customers is so worth is that the math all works out.
Another example: "Brand B" has an AOV of $70 and in the first five years after a first purchase the customer spends $22. This company has no choice but to be exceptionally disciplined in their marketing approach. No waste. None. They can only afford tactics that are guaranteed to work and deliver profit during the acquisition transaction. Their "Share of AOV" is poor ... just 31%.
There are times when you read stuff from the LinkedIn experts, telling "brands" what they "must do" to be successful. Well, "Share of AOV" dictates what a "brand" must do ... if the company wants to be profitable.
There is a reason we always end up with department stores, or Walmart, or Target, or Amazon, or Marketplaces. The extended merchandise assortment (which comes at a cost, by the way, but frequently at a cost that is lower than wasteful marketing spend) drives "Share of AOV" much higher, allowing the company to generate a ton of downstream profit.
There is reason most newer enterprises hit a ceiling. Their merchandise assortment is too narrow, meaning "Share of AOV" is too low and eventually the brand reaches all of the prospects it can possibly reach.
Smart marketers optimize the relationship between acquisition AOV and downstream Share of AOV. From there, smart marketers do everything they can to increase merchandise productivity (i.e. personalizing the assortment to customers), increasing profitability, thereby increasing how much can be spent to acquire a customer.
