Just like hyperlinks are a part of the writer’s life, while writing the content. Similarly, when people like to have interactions on Facebook they make hashtags. It is one of the universal elements to be used in the daily lives of many individuals. If you create a Wikipedia page for your company, and to share it with a larger audience you just have to mention the link on the Facebook post. With this, you may add 1 or 2 hashtags that are general for the people to click and explore the word or phrase. Do you think you require any examples?
