A successful social-media marketing strategy can begin simply enough by creating (or leveraging) quality content to attract visitors to your site. Start with a relevant blog, quote, video, news release or knowledge nugget and then share it with your prospects and clients. For example, you might want to create a blog entry about professional liability insurance for engineers and then tweet it, pin it (if it has a graphic), add it to Stumble Upon, post it to Facebook, share it with LinkedIn groups or add it to Google+. Remember to localize your content if you sell in just one geographical area ("New York professional liability insurance").
One easy way to share your content is by using the social-media chiclets at the bottom of your blog. Or you could take advantage of the integrated social media offered by one of the major providers. For example, you could use LinkedIn to automatically tweet your LinkedIn posting. Post a YouTube video, voice over PPT, recorded webinar, etc., and share it in one of the ways noted above. You can use a simple social-automation solution such as Bufffer or HooteSuite, depending upon your needs and goals. When possible, expand your blogs into e-published articles on sites such as Ezine, ArticlesBase or Amazine.
