For a long time now, there have been arguments on the online channels that make up social media. To most people, Facebook, Twitter, Instagram, LinkedIn, Pinterest, are the channels that make up social media. However, these are just but one category called social networking platforms.
Others social media categories include bookmarking sites such as StumbleUpon, which allows users to save and organise links to their favourite websites. Social news sites such as Reddit allow users to post article and news links on the sites for other users.
Media sharing sites such as YouTube are social media platforms that allow users to share multimedia content. Microblogging sites are social media platforms that allow users to submit short entries that include links to products and services. Twitter is one of the most infamous microblogging websites today.
Finally, forums and blog comments are also part of social media, and they provide an opportunity for users to engage in conversations by making posts and responding to messages left by other community members.
With that said, a social media marketing agency will help you identify all the available social media channels that will help you engage with your target audience. For this reason, you need to ask them questions to test their competence on a wide range of social media channels.
