Multi-channel Marketing：多开一个渠道何时不再划算

Multi-channel marketing is a practitioner term for reaching and selling to customers through more than one channel, such as a website, a marketplace, email, social media, or a store. It covers two things: a company being present in several channels, and customers actually using several.

This entry covers both meanings, and it counts sales channels, where an order is placed, alongside communication channels, where a message reaches someone. Most of the hard evidence sits on the sales side, and the research on communication channels is much thinner.

One idea runs through everything below. Being in many channels is common. Making customers use many channels is a bet that only sometimes pays.

Multi-channel marketing: two things the term gets used for

The first meaning is about the company. A business sells through its own website, lists products on a marketplace, keeps a store open, and sends offers by email. The questions here are coverage, cost, and whether the team can run every channel well at once.

The second meaning is about the customer. One person browses on a phone, checks a price in a store, and orders online a week later. The question here is value: is a customer who uses several channels worth more, and can marketing create more of them profitably?

A company can have plenty of the first without much of the second. The official statistics below measure presence, while the field experiments measure behavior. Mixing the two is the most common mistake with this term, because "most firms sell in several channels" says nothing about whether multichannel customers are more valuable.

The term is also separate from channel marketing, which usually refers to the partners and intermediaries that carry a product to market.

Multi-channel, cross-channel, omnichannel: where each starts

The research reviewed for this entry produced no authoritative, sourced definition separating these three labels. What follows is an editorial working distinction, not a standard.

Multi-channel is the simplest arrangement. More than one channel exists, and each can run on its own targets, budget, and data. A shopper might see a social post and later buy in a store, yet nothing connects those moments on the company side.

Cross-channel marketing describes journeys where one channel deliberately hands the customer to another, such as an email that sends people to store pickup. Omnichannel marketing describes the goal of making channels behave like one system, with a shared customer record, shared inventory, and returns that work the same way everywhere.

In practice the labels blur. One field experiment cited below has "Omnichannel Commerce" in its title, yet it tests whether pushing store customers to buy online helps or hurts total sales, which is a multi-channel behavior question. The three terms read best as points on a scale of integration, not three rival strategies.

How common it is, and what the official numbers actually measure

The clearest large-scale data on channel presence comes from Eurostat, the EU's statistical office. Its 2025 enterprise survey asks about the previous year, so the figures describe 2024, for enterprises with at least 10 persons employed. Every Eurostat figure here was checked against Eurostat's published page (verified).

Owned sites and marketplaces overlap

In 2024, 23.59% of EU enterprises made electronic sales. Most did it through websites or apps only (17.99% of all enterprises). Another 2.9% sold only through electronic data interchange, the machine-to-machine ordering systems businesses use with each other, and 2.7% used both routes.

Among enterprises with web sales, 85.65% sold through their own website or app and 45% through an e-commerce marketplace. Many firms do both, so the two shares cannot be added, and Eurostat's page does not publish the overlap.

Where the revenue lands

Presence and revenue tell different stories. Sales through enterprises' own websites or apps made up 7.08% of total EU enterprise turnover in 2024, against 1.30% through marketplaces, which Eurostat describes as more than five times higher. Web sales overall accounted for 8.39% of turnover, electronic data interchange for 11.07%, and total electronic sales for a reported 19.49%.

Marketplaces are widely used, yet in aggregate they carry far less turnover than owned sites. These are totals across all enterprises in scope, though, so they do not show that a marketplace is unprofitable for any single firm, and they say nothing about fees or margins.

What these numbers can't tell you

Official statistics like these measure where enterprises sell. They do not measure whether multi-channel marketing raises revenue, and they hold no customer-level data. They also cover the EU only.

The research behind this entry found no recent, independent causal benchmark showing that multi-channel marketing lifts conversion, retention, or return on spend by a general amount. That does not prove no such study exists, only that none met the source standard used here. No national multichannel adoption rate for Indonesia was found either.

The gap is widest for communication channels. For email marketing or social media, the figures that surfaced came from vendor statistics roundups that could not be traced to a primary source, so none are used here.

Does making customers multichannel pay?

This is the second meaning of the term, and the stronger evidence sits here, because researchers can randomize who gets encouraged and compare against a control group.

One campaign in four

A field experiment by Elisa Montaguti and Sara Valentini of the University of Bologna and Scott A. Neslin of Dartmouth's Tuck School of Business, published in Marketing Science, tested this with more than 30,000 customers of a European multichannel book retailer. The team crossed two messages, the benefits of shopping across channels and the retailer's value proposition, with and without a financial incentive. That made four campaigns, plus a control group.

Only one worked: the multichannel-benefits message with no financial incentive. It produced more multichannel customers and more profit than the other campaigns and the control, with a return on investment of 93%, according to the INFORMS release on the study (verified). The other three did not raise multichannel customers or profits against the control, and their returns were negative.

How you encourage channel use mattered as much as the decision to encourage it, and adding money did not help. Still, this is one retailer in one category, studied before 2016.

Correlation isn't causation

Neslin named the underlying problem in a 2014 Tuck interview. Multichannel shoppers are more profitable on average, which tempts companies to create more of them. But customers who already like a store may become multichannel because they are loyal, not the reverse. Only an experiment with a control group separates the two.

So a dashboard showing that multichannel customers spend more is not evidence that pushing customers into more channels will raise spending.

When more channel use comes with less revenue

A 2025 Journal of Retailing study by Lara Lobschat, Lisan Lesscher, Peter C. Verhoef, and Katherine N. Lemon examined transaction records from one large international hospitality company. According to its abstract (verified), greater multichannel use was associated on average with lower customer revenue. The pattern was an inverted U: moderate use was linked to the highest revenue, both low and high use to weaker results.

Brand tier changed the picture. Only middle-tier brands benefited from more multichannel behavior, while low-tier and high-tier brands saw flat or negative effects. The abstract reports no effect sizes.

This study and the bookstore experiment come from different settings, a European book retailer and a single hotel group, and measure different outcomes. They should not be merged into one verdict on direction.

Distance can flip the result

A 2020 MIS Quarterly field experiment by Xueming Luo and co-authors, titled "Complementarity and Cannibalization of Offline-to-Online Targeting: A Field Experiment on Omnichannel Commerce," followed more than 11,200 customers of a large department store (verified, abstract). Once induced to buy online, customers living near the store raised offline spending and total sales by 47%. For customers living far away, total sales fell by about 5.7% for each additional kilometer of distance.

The two numbers only make sense together. The same push toward a second channel helped one group and hurt another inside a single company.

Complement, cannibalize, or just move sales around

An added channel can complement the others and bring in sales that would not have happened. It can cannibalize, taking sales existing channels would have made anyway, often at a different margin. Or it can shift demand, leaving totals similar but changing how efficiently each channel works.

Warby Parker is a reported example of the third case. According to a University of Delaware UDaily report dated November 23, 2015, on research by David R. Bell of the Wharton School, the eyewear company sold online and ran a home try-on program before opening showrooms. After a showroom opened, demand in that area rose 9% compared with similar customers elsewhere. Home try-on sales fell 5%, but the company sent out 8% fewer sample pairs (reported). Customers who wanted to touch the product moved to the showroom, so the try-on program served the customers it suited best. This is one company, described through university news coverage, so treat it as an illustration, not a benchmark.

There is a market-level version too. In the same 2014 interview, Neslin described the wider multichannel race as a prisoner's dilemma. In that kind of game, when every competitor adds the same channel, nobody gains an edge, yet everybody carries the cost.

A test before adding the next channel

This checklist is an editorial synthesis of the studies above, not a tested framework.

1. Which meaning are you paying for? Presence in a channel and changed customer behavior are different goals with different costs.
2. Who is the channel for? The department store results split by distance, the hotel results by brand tier. Plan to measure by segment.
3. What will it take from? Name the channels most likely to lose sales, and decide how you will check total sales, not just the new channel's.
4. How will you encourage use? In the bookstore experiment, the incentive campaigns lost money.
5. What would prove it worked? "Multichannel customers spend more" cannot answer that. Set up a comparison group before launch.

Measuring it without fooling yourself

Marketing attribution assigns credit for a conversion across the touchpoints a customer passed through. It helps you understand paths, but it describes what happened rather than what caused it, so it inherits the correlation problem above.

Incrementality asks what would have happened without the channel, by comparing a group that received it with a group that did not. The bookstore and department store studies both used that logic, which is why they carry more weight than comparisons of existing customers.

In practice, hold out a region, a store catchment, or a random set of customers at launch, then compare total sales across every channel. Watch the channels most at risk of cannibalization as closely as the new one, and look at longer-run measures such as customer lifetime value, since a channel that only moves purchases around can look like growth for a quarter.

Frequently asked questions

What is multi-channel marketing in simple terms?

It means using more than one channel to reach and sell to customers, such as a website, a marketplace, email, social media, or a store. It covers both a company's presence in several channels and customers using several of them.

What is the difference between multichannel and omnichannel marketing?

No sourced definition separating them was found for this entry. As a working distinction, multi-channel means several channels exist and may run separately, while omnichannel aims to make them act as one system with shared customer data and inventory.

Is multichannel marketing always more profitable?

No. In a European bookstore experiment, only one of four campaigns encouraging multichannel shopping paid off. A 2025 hotel-group study linked greater multichannel use to lower average customer revenue, with only middle-tier brands benefiting.

What is an example of multichannel marketing?

Selling through an owned website and a marketplace at the same time. In 2024, 85.65% of EU enterprises with web sales used their own site or app and 45% used a marketplace, many doing both.

How do you measure whether a new channel is working?

Compare a group exposed to the channel with a holdout group, and track total sales across all channels. Attribution shows paths, but only the comparison shows what the channel added.

What are the main risks of multichannel marketing?

Cannibalizing existing sales, paying for incentives that do not return their cost, and effects that differ by segment. In one department store experiment, pushing online purchases raised total sales by 47% for nearby customers but cut them by about 5.7% per additional kilometer for distant ones.
