Why are the number of channels growing in B2B marketing and how to respond cost effectively?

The number of channels used in B2B marketing has increased rapidly in recent years. The change is not simply driven by the emergence of new platforms or shifting marketing trends. A much larger transformation is taking place in the way customers search for information and make purchasing decisions. Information discovery has become fragmented across multiple channels, buying journeys have moved increasingly online and decision making now involves several stakeholders with different perspectives and priorities.

Where a company could previously rely on a website, a newsletter and occasional campaigns, buyers today form their understanding of businesses through several touchpoints before ever speaking with sales. Companies are encountered through search engines, LinkedIn, webinars, newsletters, podcasts and increasingly also through AI driven search experiences as part of research and comparison.

In many organisations this creates growing pressure to produce content for an expanding number of channels. The challenge, however, is rarely multichannel marketing itself. More often, the issue is that content is still managed in ways that no longer reflect modern buying behaviour.

The buying process no longer happens in one place

B2B buying no longer follows a straightforward step by step process. Decision making now involves more people, each with their own goals, questions and information needs. End users may focus on practical benefits, leadership teams on strategic impact, finance on costs and IT on technical implications.

At the same time, these stakeholders are rarely looking for information in the same places or at the same moment. One person may compare solutions through search engines, another may follow expert discussions on LinkedIn and a third may rely on webinars, newsletters or peer recommendations. A significant part of the buying journey takes place before sales is ever contacted.

This is exactly why the number of channels has grown. The point is not that companies need to be visible everywhere at all times. The reality is that the customer journey is now built simultaneously across multiple environments.

Digital self service has changed the role of content

More B2B buyers want to explore products and services independently before engaging with sales. Information is consumed when the buyer needs it, not when the company is ready to present it.

This has made content a much more significant part of the buying experience. Websites, search engines, social media, newsletters, webinars, customer stories and different review environments together form a network where buyers build their perception of companies.

AI powered search and recommendation systems are also changing how buyers discover and compare information. Content is no longer simply supporting material for marketing. It shapes how customers understand their challenges, evaluate alternatives and decide which companies are worth engaging with further.

Cost efficiency comes from prioritisation, not larger production volumes

As the number of channels grows, the first instinct is often to try to be present everywhere. Over time, this easily leads to a situation where content output grows faster than business impact. Cost efficiency rarely comes from producing more. It comes from focusing resources more deliberately. In practice, this means:

1. Prioritise channels based on your audience: Not every channel matters equally for every company. The more important task is identifying, through analytics, customer interviews and sales insights, the environments where the target audience genuinely forms opinions and compares solutions.

2. Focus your efforts more precisely: Especially in longer B2B buying journeys, more organisations are adopting Account Based Marketing, or ABM, where efforts are focused on carefully selected companies and buying groups instead of broad reach. The goal is not maximum visibility but meaningful presence in the places where key audiences are evaluating their options. According to HubSpot (2025), 81 per cent of marketers using ABM believe it delivers better ROI than other marketing approaches.

3. Prioritise owned channels: Social media and paid advertising may spark initial interest, but their primary role is often to direct audiences towards channels the company controls itself. Websites, search focused content, newsletters and CRM systems form a foundation where the company owns both the customer experience and the long term value of the content. Their value lasts considerably longer than that of individual campaigns.

4. Use the same expertise across multiple channels: A growing number of channels does not mean every platform requires entirely new content. In our earlier article, we discussed the principle of “write once, publish many times”. When one strong expert level piece of content serves as the starting point, the same expertise can simultaneously support search visibility, social media discussions, newsletters and sales enablement materials.

5. Measure business impact, not just visibility: As the number of channels increases, measurement becomes even more important. Traffic, reach and engagement matter less than understanding which channels generate qualified leads, support sales and contribute to long term demand creation.

Sales, marketing and automation support each other

As channel ecosystems expand, collaboration between sales and marketing becomes increasingly important. Content is not only about visibility. It also supports the sales process itself. Marketing content can help sales teams open conversations, answer recurring questions and support buyers as they evaluate alternatives.

The collaboration works in both directions. Feedback from sales reveals which questions repeatedly arise in customer conversations, where buyers hesitate and what type of content would help move decision making forward. It is equally important that sales teams have visibility into marketing content and know how to use it effectively in customer interactions. When content is used in the right situations, it becomes more than a visibility tool. It actively supports sales conversations and progression through the buying journey.

Marketing automation adds further scalability. It allows content to be aligned with different stages of the buying journey, supports systematic lead nurturing and enables personalised communication without everything being handled manually. AI can speed up drafting, summarising, versioning and adapting content for different channels. Technology works best, however, when it is built on a clear content structure and a shared understanding of the expertise the company wants to strengthen.

Competitive advantage comes from a structured system

The growth in channel numbers is unlikely to be temporary. It is a consequence of permanently changed buying behaviour. Customers now build understanding across more environments, at different times and through different sources. The question is no longer whether companies should be present in more channels. The question is whether marketing can operate effectively in a world where customer attention is fragmented.

The cost effective response is not to increase content production at the same pace as new channels emerge. It comes from the ability to prioritise, focus and build a structured system where the same expertise strengthens multiple touchpoints simultaneously.

Over the long term, competitive advantage is unlikely to belong to the organisations publishing the most content or appearing in the highest number of channels. It will belong to those capable of turning an increasingly complex channel landscape into a coordinated system where every piece of content, every channel and every customer interaction strengthens the next. That is when the cost of multichannel marketing begins to transform into long term business value.
