Key Takeaways

B2B buyers are everywhere, not just LinkedIn – from Google searches to Instagram scrolling and BVOD streaming, decision-makers move fluidly across channels, making a multi-touchpoint strategy essential.
Trust drives conversion – content, thought-leadership, and influencer partnerships remain central to building authority and credibility in complex, high-value B2B purchase journeys.
Technology is reshaping efficiency – programmatic, AI-powered buying, and automation make campaigns more scalable, but human oversight is still vital to ensure strategy, creativity, and brand-building remain on track.

Digital advertising has long been considered a B2C playground, with glossy consumer campaigns dominating social media feeds and search engines. But in reality, the B2B landscape has changed dramatically. Decision-makers are still human; they scroll LinkedIn during work hours and Instagram in the evening, they stream programmes on ITVX and Sky, and they Google solutions to business challenges late at night.

As a result, the digital advertising ecosystem for B2B brands has expanded well beyond trade magazines and cold outreach. Today, a well-crafted digital advertising strategy can engage business buyers across multiple touchpoints, guiding them from awareness through to conversion.

This guide dives into the core digital channels available to B2B marketers, their strengths and weaknesses, and—most importantly—how they contribute to an effective marketing mix.

1. Search Engine Marketing (SEM) & SEO – The Foundations

For many B2B buyers, the journey starts with a search bar. Whether it’s “best logistics software” or “top commercial law firms,” search engines remain the gateway to discovery.

Why it matters

Search activity is intent-driven. Unlike display ads or social posts that interrupt someone’s browsing, paid search and SEO target people when they’re actively seeking answers. For high-consideration B2B purchases, capturing that moment is invaluable.

Paid Search (PPC)

Search ads allow brands to appear at the very top of Google results when prospects are researching suppliers. This ensures visibility during the crucial research stage.

Upsides: fast to activate, measurable ROI, scalable based on budget.
Downsides: cost-per-click (CPC) for B2B terms can be extremely high (think £15–£50 per click in some industries). Without expert management, budgets can evaporate quickly.

SEO (Organic Search)

While slower, SEO builds long-term credibility. Ranking organically signals authority, and unlike PPC, it doesn’t disappear when the budget pauses:

Upsides: sustainable, high trust factor, boosts brand visibility.
Downsides: requires continuous investment in technical fixes, content, and link building; results may take months.

Role in B2B marketing: Search ensures you are present at the “solution-seeking” stage of the funnel. Combining PPC for immediacy with SEO for long-term growth creates a balanced acquisition strategy.

2. Social Media – Beyond LinkedIn

Social media is now an essential part of the B2B toolkit—but not just LinkedIn. Decision-makers don’t stop being consumers when they leave the office.

LinkedIn – The classic B2B network

With its ability to target by job title, seniority, company size, and industry, LinkedIn is unparalleled for account-based marketing (ABM). Sponsored posts and InMail campaigns make it easy to deliver personalised messaging.

Upsides: unmatched B2B targeting, professional environment, ABM potential.
Downsides: expensive CPCs (often £5–£12 per click), audiences wary of generic sales pitches.

Instagram & Other B2C Platforms

Instagram, Facebook, YouTube, even TikTok, can all serve B2B purposes. Why? Because business decision-makers scroll through them daily. A procurement officer who spends the day on LinkedIn might spend the evening on Instagram looking at interiors, where your SaaS ad could appear.

Upsides: cost-effective reach, strong for visual storytelling and employer branding.
Downsides: limited B2B targeting precision; requires creative tailored to the environment.

Role in B2B marketing: Social allows brands to nurture awareness and stay front-of-mind across both professional and personal digital spaces. Used correctly, it complements search by building brand familiarity before intent kicks in.

3. Programmatic Display Advertising

Display has matured from banners on websites to highly targeted programmatic campaigns across premium publisher inventory.

Why it matters

The average B2B purchase involves 6–10 decision-makers. Programmatic ensures your brand is visible repeatedly across the websites, publications, and apps they consume.

Upsides: scale, precise targeting (contextual, behavioural, company-level), retargeting capabilities.
Downsides: brand safety concerns if campaigns aren’t managed well; potential for wasted impressions if targeting is too broad.

Role in B2B marketing: Ideal for building brand awareness and keeping your name in front of a fragmented buying committee. Works best when layered with retargeting to re-engage prospects who visited your site but didn’t convert.

4. Email Marketing & Marketing Automation

Email is often underrated, but in B2B it remains one of the most effective tools for nurturing leads through a long sales cycle.

Why it matters

Unlike consumer purchases, B2B deals can take months—or years. Automated nurture campaigns ensure consistent communication with prospects at every stage of consideration.

Upsides: low cost per contact, highly personalisable, measurable engagement (opens, clicks, conversions).
Downsides: reliant on quality CRM data; risk of fatigue if content is too frequent or irrelevant.

Role in B2B marketing: Acts as the “glue” that holds together wider digital activity. Search and social may generate leads, but email nurtures them with case studies, insights, and offers until they’re ready for sales engagement.

5. Content Marketing, Webinars & Events

Content is the engine that powers modern B2B digital marketing.

Why it matters

Decision-makers crave evidence and expertise. High-value content builds trust, positions your brand as an authority, and generates leads.

Formats: whitepapers, thought-leadership blogs, webinars, podcasts, video explainers, case studies.
Upsides: builds long-term credibility, fuels SEO, provides assets for paid promotion.
Downsides: resource-intensive; requires consistent production and a clear distribution plan.

Role in B2B marketing: Content educates, demonstrates value, and differentiates your brand. Webinars and events, in particular, remain high-performing because they combine information with human interaction—critical in trust-based B2B relationships.

6. Influencer & Thought-Leader Marketing

B2B buyers look to peers, analysts, and industry figures for validation. Partnering with respected voices can dramatically increase brand credibility.

Why it matters

Trust is the single most important currency in B2B marketing. Influencers (in this context, often niche experts or consultants) lend authority to your message.

Upsides: strong social proof, can simplify complex subjects, positions your brand within industry conversations.
Downsides: ROI measurement can be murky; requires careful selection of credible partners.

Role in B2B marketing: Humanises your brand and adds authenticity. For example, a cybersecurity firm partnering with a known security analyst for a webinar immediately gains authority with decision-makers.

7. BVOD & Streaming Platforms – The Emerging Frontier

Broadcast Video on Demand (BVOD) is reshaping B2B advertising. Platforms such as ITVX, All4, and Sky AdSmart now allow granular targeting—something once exclusive to digital.

Why it matters

Senior executives may not scroll TikTok, but they almost certainly stream ITV dramas or Sky Sports. Advertising within these environments provides scale and prestige, while self-serve tools are making it more accessible for smaller brands.

Upsides: trusted environments, rising self-serve models, strong attention levels.
Downsides: production costs for high-quality creative; attribution beyond brand awareness is still evolving.

Role in B2B marketing: Perfect for brand-building at scale—especially in industries where reputation and trust are essential (finance, legal, tech). It also brings a “halo effect” as B2B buyers see your brand alongside household names.

8. Programmatic AI & Automated Buying

AI-powered campaign management is transforming how media is bought. Google’s Performance Max and Meta Advantage+ are just two examples of platforms automating budget allocation and targeting.

Why it matters

AI reduces manual optimisation, analyses vast amounts of performance data, and reallocates spend dynamically to where it performs best.

Upsides: efficiency, access to predictive modelling, strong for scaling campaigns.
Downsides: lack of transparency (“black box” problem), reduced control for advertisers.

Role in B2B marketing: Use AI-driven buying to optimise mid- and lower-funnel campaigns where efficiency is critical. However, maintain human oversight for strategy, creative, and brand-building.

Final Thoughts

Digital advertising for B2B has evolved far beyond trade publications and sales brochures. From intent-driven search to brand-building BVOD campaigns, decision-makers are reachable across multiple digital touchpoints—both professional and personal.

The most successful B2B brands don’t rely on a single channel. They integrate search, social, content, programmatic, email, and events into a unified strategy that educates, builds trust, and converts leads into long-term partnerships.

At One Day Agency, we help B2B brands navigate this complexity—designing campaigns that align creativity with performance and ensure your brand reaches the right people, in the right places, at the right time.
