    Our Story

    SmartB2B.Marketing started from a simple observation: most LinkedIn marketing attempts fail not because of the platform but because of weak strategy, vague targeting and activity without structure. We built our work around fixing that. 20+ years in marketing. 200+ LinkedIn projects. Award-winning work. We focus on lead quality, targeting, and making ads, organic, and social selling work together. No junior outsourcing. If LinkedIn matters for your business, it should be done properly.

    What Sets Us Apart

    Founder-Led Expertise

    Your LinkedIn strategy is built and guided by senior specialists, not passed to junior freelancers. We bring 20+ years of marketing experience, 200+ LinkedIn projects and hands-on execution with full accountability.

    Structured LinkedIn Systems

    We connect LinkedIn strategy, ads, organic content, social selling and employee advocacy on LinkedIn into one clear system. This helps clients avoid random LinkedIn activities, scattered campaigns and disconnected tests.

    Focus on Lead Quality

    We focus on attracting the right people, not just increasing clicks, impressions, or generic leads. Our work is built around stronger targeting, clearer messaging, better offers and measurable business value.

    Commonly Asked Questions

    Our work is founder-led, meaning senior experts design and guide the strategy and key decisions. There is no junior outsourcing, templated delivery, or generic “best practices” applied without context. We build structured LinkedIn systems across advertising, organic, and social selling, not isolated campaigns. Many agencies focus only on ads, or only on organic. But we ensure that visibility, trust, lead generation and relationship-building work together. We focus on precision. This includes clear targeting, structured messaging and realistic projections for leads, budget and timelines. Wherever possible, we provide grounded benchmarks instead of vague “it depends” answers. Our model is flexible. We do not lock clients into long-term retainers. You can work with us on execution, strategy, or training, depending on your internal capabilities. We continuously optimise for lead quality and cost efficiency, not just activity. The focus is on improving CPL, conversion and pipeline contribution over time. We also bring a strong European quality and compliance mindset, including GDPR awareness, while working across both European and US markets. Finally, we rely on proven work. Our approach is based on 200+ LinkedIn projects, visible case studies and real client results, not assumptions or empty promises.

    Successful LinkedIn marketing requires collaboration. We need a clear understanding of your offer, target audience, positioning and sales process. Your input will be essential for developing strategy, refining messaging, validating assumptions and evaluating lead quality. Timely feedback and communication are also critical, especially, during testing and optimisation phases. LinkedIn performs best when marketing and sales are aligned, follow-up is consistent and there is a shared understanding of what constitutes a qualified lead. We also expect a realistic mindset: LinkedIn is not an instant-results channel but a system that builds momentum over time. When these elements are in place, LinkedIn can become a reliable source of high-quality opportunities.

    We provide both strategy and execution across all core LinkedIn areas: advertising, organic marketing and social selling. Our work is built as a structured LinkedIn system, not as separate activities or random tasks. Some clients work with us for complete strategy and hands-on execution. Others need a detailed LinkedIn blueprint, audit or strategic guidance that their internal team can implement. We can also teach and train your team to manage LinkedIn more effectively in-house. Our founder regularly provides LinkedIn trainings, workshops and presentations for companies and events. Execution can include LinkedIn Ads management, organic content direction, company page optimisation, founder or expert thought leadership support, employee advocacy logic, profile optimisation, Sales Navigator guidance and social selling frameworks. However, we only execute strategies that we have prepared or thoroughly reviewed and rebuilt. This is important because we cannot be accountable for results if the strategic foundation was created elsewhere and is not aligned with our methodology. Our focus is not isolated execution. It is building a LinkedIn system that works consistently across visibility, trust-building, lead generation, and relationship development.

    No. We do not structure our work to create dependency or lock clients into long-term commitments. Our goal is to build a LinkedIn system that is clear, structured, and transferable, so you understand not only what should be done, but why it should be done. You can choose full execution but you can also run everything in-house if you prefer. Some clients start with strategy, setup, and campaign structure, then continue independently with occasional consulting. Others prefer ongoing support for optimisation, content direction or result reviews. We also offer detailed DIY manuals for LinkedIn Ads and organic LinkedIn marketing, which is rarely offered by typical agencies. These manuals explain the logic, setup, structure and practical steps, so your team can understand and manage the work internally. This means your team is not left with a “black box” system that only we understand. Our role is to make your LinkedIn marketing stronger, not to make you dependent on us.

    You can. The question is what you expect LinkedIn to deliver. Lower-cost execution often focuses on activity: launching campaigns, posting content, or generating leads without a clear system behind it. This can create the appearance of progress, but without strong targeting, messaging and offer structure, the results are often inconsistent or low quality. LinkedIn is not a volume channel. It is a precision channel. Small strategic mistakes in audience, positioning, or funnel structure can significantly impact cost per lead and lead quality. In many cases, companies do not lose money because LinkedIn “does not work,” but because it is used without a clear system. Our work is designed to reduce that risk. We focus on building a structured approach across ads, organic, and social selling, aligned with your business model and sales process. This typically results in better lead quality, clearer optimisation paths and more predictable results over time. If your goal is short-term activity at the lowest cost, there are many options. If your goal is to make LinkedIn a reliable part of your growth, the approach needs to be different.
