Sponsor a video contest in which customers create a one-minute video about why they like your business, products or services. Ask them to send the videos to you and post them to your Facebook page. Invite visitors to vote on which video should win a cash or merchandise prize. Include an email opt-in on your Facebook page. Be sure to follow Facebook’s rules regarding contests.
In this context, I guess each post can’t be thought of in isolation, but in terms of a mini content ecosystem that comprises of a great blog post optimised for on-page SEO, an upgrade to that post tailored for that specific content, various on-page email conversion points including an exit pop-up or similar -and then you combine all this with your off page link building and outreach efforts. That could be over 5,000 words of content all in just that one package.
