This is the free-spirited cousin of on-page optimization. Off-page SEO refers to incoming links and other outside factors that impact how a webpage is indexed in search results. Factors like linking domains and even social media play a role in off-page optimization. The good news is that it’s powerful; the not so good news is that it’s mostly out of an inbound marketer’s control. The solution? Create useful, remarkable content and chances are people will share and link to it.
