Which type of posts can be helpful to generate leads?

[limbo]

I think social media is the best way to generate the leads.
So I would like to suggest you related facebook leads, Make Facebook Events for Webinars, Use Targeted Advertising to Extend Your Content’s Reach, Build Forms on Tabs.

Social Media Marketing is one of the best ways to marketing with generating leads. Use Linkedin to get the lead.

Social media marketing isn't the concerned topic here.
