Let visitors to your site get to know you better by giving them a bit of background on yourself and your soon-to-be spouse (which is especially helpful for guests, like a friend's plus-one, who might not know you that well). Tell the story of how you met, have a link to the video footage of the proposal (on YouTube, Facebook Live or elsewhere), share a few of your favorite couple shots and post photos of wedding party members so guests will recognize who's who at the wedding. You might also want to upload a photo album and tag it with your wedding hashtag. That way you can stream all the moments along your journey to the altar from Instagram and Facebook, or aggregate public snaps posted using your hashtag, on your wedding website.
Just beware of going overboard with information. Our guess is that visitors won't feel like clicking through a slideshow of the entire story of your lives together or an extensive album devoted to your pet (aka the ring bearer).
