All Social Messages scheduled on CoSchedule will publish exactly as if they were published directly by Twitter's native network.
CoSchedule will try to display link post's previews inside of the social message preview. Typically if the link’s website has Twitter Cards enabled a preview should display. To verify if the site you are linking to has a Twitter Card, and to see what it will look like, enter the link into Twitter’s Card validator.
