There are many paid and free WordPress plugins that allow you to automatically publish your posts on social media. Social Networks Auto-Poster is one of the best plugins I’ve used. It supports most popular social networks such as Facebook, Twitter, Google+, Blogger, Tumbler, Flickr, LinkedIn, LiveJournal, DreamWidth, Flipboard, Instagram, Telegram, Line. Social Networks Auto-Poster is fully compatible with WooCommerce, allowing online shops to use it to inform about their products on social networks. In addition to plugins, I use Facebook promotion tools. I buy likes at famoid.com to raise the asset on my page.
