There's absolutely no need to post the same content across multiple channels yourself; set up this Twitter-Facebook Pages integration to do it for you instead. It'll then trigger whenever you post a new tweet, automatically sending your text and image to your Facebook Page so both groups of fans know the latest news at once.
Facebook Pages lets you connect with your customers, fans and followers on the world's largest social network. Share relevant content to engage people who Like your page, create events to build and grow your community, and run a Facebook ad campaign by targeting location, age and more.
