What are some different social media marketing tools or technology available to marketers?

"As a developer, my work with corporate marketing departments gave me an understanding of different tools available to marketers to help them manage social media marketing efforts. There are platforms that help them track and manage their marketing on different social media channels in one place. A popular product in this category is Buffer - a tool which supported by many third party applications. Another type of tool is related to social media content management. Buzzsumo is an example of this type of tool as it, using data, helps determine worthy content topics and identifies the best social media channels to post the content on."
