What you need is not numbers but real people, a live audience, to interact with your own timely and relevant content. You also need to be able to respond and keep the conversation going when it happen, not whenever someone has some spare time to post a comment or tweet a reply. The lifespan of a Facebook post is measured in a few hours and that of a tweet in minutes. A conversation extends the life of your content if you catch it when it happen, not later today or the day after.
It is neither difficult or expensive to make good use of social media. There are countless resources on the Internet to learn what to do and what not to do, including specialized blogs specifically addressing social media for the tourism industry. The bottom line is that, like any other business practice, there is no secret or magic shortcut. You simply need to handle social media in the same way as you handle all other aspects of your business: seriously with a plan and staff time allocated to that and not as an extra task to do on spare time. Get help from a consultant to get you started with a plan and directions if need be, but keep the work in-house with your own team. It is far easier, and seriously motivating, to get your own people involved to learn how to promote the business they work for and be rewarded with the results. Your own team lives through the daily dynamic of your activities, and once they learn how to present content, posts, blogs or tweets and how to interact with the audience, they will be your best ambassadors and marketers.
