New to B2B sales ,not sure where to start with lead generation. I will not promote

Hi everyone, I’m new to B2B and recently built a B2B services business. We’re getting some traction so far, but I’m not sure how to consistently generate sales. From my initial research, I’ve come across a few options: LinkedIn Sales Navigator and InMail Tools like Lusha for finding emails from LinkedIn Email-finding tools such as RocketReach Outreach platforms like ReachInbox LinkedIn ads SEO and content marketing Ebooks, lead magnets and other resources Cold email and social media ads The problem is that I’m not sure where to start. Should I: Build a targeted prospect list and start sending cold emails? Focus on LinkedIn outreach first? Run LinkedIn or social media ads? Create ebooks or lead magnets? Invest in SEO? Collect market data and use it for email campaigns? I feel like I’m looking at too many options and getting confused. I’ve also read that it’s better to focus on two or three channels first instead of trying everything at once If you’ve built a B2B business or handled sales for one before, I’d really appreciate your advice: What channel worked best for you in the beginning? What would you avoid if starting again? Should I focus on outbound sales first or build inbound marketing? What tools or processes helped you get your first consistent leads? Any practical advice would be really helpful.
