For this reason, if you see a good story or idea on Twitter, retweet it (this copies the tweet into your own feed, meaning your followers can see it). On Facebook or Instagram, either share a post or draw attention to it, if you think being associated with the thought boosts your own brand. By giving exposure to things you like, you might just win an ally in the person who originally posted the content (assuming you give him or her the credit they deserve when linking to it). This might mean they do the same thing in return in the future. This will further grow your following.
The online lead generation is a multi-billion dollar industry. Done right it can be far more profitable than many imagine. Everyone that I know that is in the business and knows what they are doing, for the most part, does 6-7 figures. While that's a huge range, much comes to one's ability to scale and effectively build / manage the infrastructure needed to scale.
