There is no question that conferences, expos and trade shows are effective for multiple reasons, as they gather various industries together in one location, for a number of days. What if you could make those few days even more effective by starting months before the event starts, and never really have it end?

Shows are all about community, and social media provides a great way to keep in touch before, during and even after the show. Think about the numbers. Between the show, exhibitors, attendees and their community networks, and people who cannot attend but are still interested, the number of contacts is huge.

Here are three different social media platforms you can use and why every show, exhibitor and attendee needs to use them in one way or another:

Twitter

This is by far my favorite social media platform for shows as it is the only one with instantaneous communication to basically anyone:

  • Tweet that you will be at the show.
  • Tweet at others who will be at the show. Before the show, try to set up meetings. During the show, try and meet up on the floor or after the event.
  • Retweet (RT) tweets by the show organizer and influencers to support them and spread the news and share valuable content.
  • Tweet with the conference hashtag (#) to make sure everyone can find your show tweets.
  • Tweet pics of the show.

Facebook

Many people have a love/hate relationship with Facebook, but it's another great platform that can still be effective. Generally, you shouldn't post more than three updates in one day, unless you really feel it is necessary.

Here are more tips for show organizers and companies.

For exhibitors:

  • Before the show, publish news that your company will be there and give the name of who from your company will be manning the booth and the booth number.
  • At the show, take pictures of your booth, with your entire team and product(s).
  • After the show, create an album of all your pictures so you can share them with clients, friends and all whom are connected with you so they can see what happened at the show.

For organizers:

  • It is important to start at least one month before the show begins, posting updates, facts and information that attendees and exhibitors need to know about your event.
  • Publish show and exhibitor news to inform attendees and media. This way, they will know exactly what to expect before they arrive.
  • Take pictures of exhibitors setting up at the show. This will generate excitement.

Pinterest

This newer social network is growing quickly for its visual appeal and ability to display lots of images.

  • Create boards where you can pin your images based on your specific industry.
  • Get the bookmarklet from their site and add it to your navigation bar to make it easier to pin.

For exhibitors:

  • Pin all of your company images from your site to specific boards well before the event starts.
  • During the show, take pictures that you can pin through the app and can still be used after the show ends.

For organizers:

  • Create boards based on the different categories or verticals your show covers.
  • Pin the logos of all your exhibiting companies.
  • Pin interesting things you see on the show floor: new products, first-time exhibitors, cool things exhibitors are doing to drive traffic to their booth, speakers, etc.

So should you use social media at your next show? The answer is an undisputed "yes" — use it, enjoy it and gain its rewards.

Take some of these tips and create a strategy that works best for your industry, show, exhibitors, attendees and media. Social media isn't a one-size-fits-all game, so start small and grow your digital brand as you go.
