How do you identify active buyers?

As for me, I am an account manager for a destination management company, and I am also the deputy of B2B. For a beginner, here’s how I identify active buyers:

Search for and gather more information about my prospects

Understand their products. For example, are they selling multi-day tours to foreign countries? Are they planning to create tailor-made routes for travelers or collaborate with local travel agencies?

Chat with them or invite them to hold a meeting

Through meetings, I can clearly understand their needs and challenges.

Keep in touch with them and follow up regularly.

Still, I must learn more about communicating with prospects more effectively and efficiently. Hope you can give me more guidance and advice. Thanks
