Did you hop on board with the giveaway idea? Then today, two days after the launch, is a good time to repromote it. Remind people about what’s going on. Maybe reveal something about the prize, or – if the prize is no secret – tell them about what they can do with the prize.
An example: let’s say your prize is an Autumn Relax Package.
Then what I’d do is ‘unbox’ that Autumn Relax Package throughout the upcoming week. Make a post today where you show one of the items in the package, and tell people to ‘keep an eye out on your Instagram Stories’, where you then slowly reveal more and more.
Or make more posts this upcoming week. You could do one every 2 days. I’d recommend still tailoring in some other posts as well, just to make sure that you don’t bore anyone who isn’t interested in winning your giveaway.
