Your home page is responsible for capturing and directing a general inbound audience, but your internal pages are where you keep the details about your company, your products and services, and what makes you unique among the competition. Learning to promote these interior pages on social media can give you a more directed traffic flow and therefore, a higher conversion rate.
But if you do this incorrectly or inappropriately, you risk coming off as self-promotional and ending up compromising your brand reputation rather than building it.
