Twitter is a micro-blogging platform that offers social and brand interaction. While most Facebook users will stay connected to the site for an average of about 1 hour per visit, Twitter users operate in smaller, more frequent interactions throughout the day. More than 750 tweets go out per second.
Twitter was one of the first sites to use hashtags, and hashtags are most effective on Twitter and Instagram.
Like Facebook, people use Twitter on tablets, personal computers and most of all mobile. Mobile is becoming one of the most used platforms for internet access. That means that it is important for your business to have a responsive website, many websites are not updated to interact sufficiently with mobile devices.
Besides having an optimized and responsive website having a social media presence will keep your audience connected to you even while on the go.
