We love to share auctions on social media (make sure to tag us! - @betterworldHQ).The best way to get publicity though is to fully leverage your community. Take the link for the auction and share it by email and social media. Ask your supporters to share, post the items on social media. Ask the people who donated an item to you to post the link to the item they gave on social media. And so on. That will deliver the maximum publicity to your auction.
