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 who don't know one of you that well). Tell the story of how you met, have a link to the video footage of the proposal (on YouTube or elsewhere), share a few of your favorite couple shots and put up photos of wedding party members so that people will recognize who's who at the wedding. You might also want to upload a photo album and connect it with your wedding hashtag to 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 too crazy—you can include a lot of info, but it should still be to the point. Our guess is that visitors won't feel like clicking through a slideshow of the story of your life together or a big album devoted to your pet (aka the ring bearer).
