Social media can help grow any business, pretty much regardless of what industry you are in. It is a great way to build your brand, inform your audience of new products and services and even get traffic to your website in the early days.
Once a website goes live it can take a number of weeks before it is picked up by the search engine spiders and shown in the search results of pages on Google and Bing. In the mean time you can start to spread the word on a multitude of social media websites such as Facebook and Twitter.
You need to try and build up a community of followers on these sites so you reach as many people as possible. Asking friends / colleagues and family to share your posts as well will also increase your reach.
Make sure that you get the right balance when it comes to the frequency of your posts. Too few and people will lose interest, too many and people will get frustrated and unfollow you.
