“Does e-commerce cannibalize in-store sales?” It’s a question I was often asked years ago as retailers struggled with the decision to take their business online. Back in late 1990’s through early 2000’s, there were no shortage of studies and expert POVs on the topic.
More than 10 years later, it feels like deja vu as this question seems to be coming up again as a hot topic. This time, it’s being driven by the rapidly growing share of online commerce as a percentage of a company’s total revenue. Many companies are seeing that 10 to 15% of their total sales are coming from online – for larger retailers, that’s translating to hundreds of million a year.
What I’ve learned that that there are few hard numbers out there on this topic. Why? Because cross-channel attribution is a messy, complicated and far from an exact science. However, there seems to be some consensus around the ratio of online spend to sales influenced offline.
1. In the table below from Forrester, they estimated that for every $1 spent online, approximately $6 of offline purchase is influenced by the online channel (2010: $177 online retail, $1,069 offline retail).
2. Terry Lundgren, the CEO of Macy’s, cited in his speech at shop.org that $1 online sales influences $5.77 spent in store over the next 10 days.
3. A Yahoo! Study (pdf) for JCPenney conducted a few years ago measured the impact of paid digital media on online and offline sales – they found a 1:6 ratio between online sales to offline sales. Although I typically take publisher studies with a grain of salt, I thought I’d reference it since it does collaborate the same ratio range.
Of course, actual mileage may vary. In fact, that ratio will vary quite a bit by the nature of your business and buying behaviors. Here are a couple of data points:
- For a beauty/fragrance client, we found that for each $1 in online redemption of a cross-channel coupon there was a corresponding $8 in offline redemption (this would be attributable to fragrance as an experienced good, more likely to be purchased in store)
- Analysis of a consumables retailer saw for each $1 of online purchases, there was a corresponding $2 of influenced offline sales (this speaks to their heavy skew toward replenishment goods/supplies vis a vis researched products)
