@darrellellens certainly Tweet that you will be exhibiting and your booth #. It is best if you’ll have something compelling to Tweet, such as “get the newest whitepaper” “see the new product” “have a demo” or other special giveaway like a drawing for something of value

Use your LinkedIn contacts selectively for those that are in your industry/target market and send them a personal message. If you are able to host a small event close by, such as a cocktail hour or lunch, invite curretn prospects and customers.

If you have a FB page that hits the right people in your target, you can use that.

If this is a popular event but a lot of your customers and prospects will not be there, promise to blog daily and remind them to read it.

Post event, take those blog posts and create a “whitepaper” such as “Top 10 things I learned at”
