Top FAQs we were asked in 2024
Is it better to combine demand generation with SEO for maximum impact?
Pairing demand generation with SEO creates a powerful synergy that can significantly accelerate business growth. This combination works effectively for several reasons:
- Long-term sustainability: While demand generation activities drive immediate results, SEO builds a foundation for sustainable, organic growth that compounds over time
- Content amplification: Content created for demand campaigns can be optimized for search, maximizing reach and longevity while improving content ROI
- Data-driven insights: SEO research provides valuable insights into customer search behavior that can inform demand generation strategies
- Cost efficiency: As SEO begins driving organic traffic, it reduces cost-per-lead from paid demand efforts
- Full-funnel coverage: SEO helps capture prospects at various buyer journey stages, complementing targeted demand generation campaigns
The most effective approach is developing an integrated strategy where SEO and demand generation share data, content, and insights to maximize overall marketing effectiveness.
How do I choose the right demand generation agency for my specific industry?
The best B2B demand generation agencies are assessed based on their proven track record (demonstrated through case studies and measurable results), B2B expertise, industry reputation, robust service offerings, and focus on ROI rather than vanity metrics.
When selecting a demand generation agency, consider these critical factors:
- Industry expertise: Look for agencies with proven experience in your specific industry who demonstrate deep understanding of your market dynamics, sales cycles, and buyer personas
- Company size alignment: Ensure the agency has experience working with companies of your size, as their processes should be tailored accordingly
- Service offerings: Evaluate their range of services to ensure they align with your needs (content marketing, ABM, paid advertising, etc.)
- Case studies and results: Request case studies from clients in similar industries with concrete metrics and ROI data
- Technology stack: Ensure their tech stack integrates with your existing tools and can scale with your needs
- Cultural fit: The agency should align with your company culture and communication style
- Pricing model: Choose an agency with a transparent pricing structure that aligns with your budget and goals
- Accountability: Consider agencies that offer revenue accountability and contractual commitments
