Salespeople on social media

I started to build my personal brand on LinkedIn in December. My target audience is sales and business development professionals.

I post real life stories like:

• How did Xerox, Electrolux, Cisco experts sold, which techniques they used.

• Plug and play persuasion and negotiation techniques.

• Problems of sellers, Problems of buyers.

• I don’t post motivational support. I like hard scientific sales like BYAF technique in action

I already have 1000 connections and I guess at least 250 of them are sales pros.

Somehow I cannot have their attention. I get 20 likes on my posts on average, but no salespeople respond.

Why is that? What am I missing?

I thought maybe their customers are also on LinkedIn - so they don’t want expose the selling techniques they utilize.

How can I grow my salespeople audience?

Note: * I don’t post in English. * My stories are long, at least 2k characters * I am not one of the lazy accounts translating popular English posts. * I don’t post generic “here are the best 5000 sales books you need to read”
