Twitter is among the social media sites. It is to share thoughts, ideas, product info, quotes… Whatever is less than 280 characters. Re-twitting is very common. As you write a tweet don’t forget the hashtags as they are super important to catch the attention of those looking for that keyword.
Some businesses use Twitter to share something about their company such as their new opening hours or their new offers. It is a fun tool to share short ideas or news.
