There are three things you need to do if you want to turn ebooks into a marketing weapon.

First, identify your main type of client – e.g. home owners if you’re a real estate agent.

Second, write an ebook that addresses their main problem or concern – e.g. The Top 10 Mistakes People Make When Selling Their Home.

Third, attach the ebook when you email them for the first time.

That will immediately establish you as a trusted authority figure. And people want to do business with trusted authority figures.
