Is Instagram a good platform for hosting giveaways? I don’t know, do you?

I'm going to be frank, I don't have a clue whether instagram is a good place for giveaways. But I'm working on it.

I have to come at it through two different angles. First, I'm curious to know whether they work when purely hosted on Instagram. Second, because I use upViral to run giveaways for my clients, I'm curious as to whether it would do any good to have upViral hook to Instagram. People in the upViral Community continue to ask for an Instagram social share, but I can't see that it would work because Instagram posts do not have links. After all, how can you get someone to go visit your give away a landing page if they don't have a link to click?

If you look at this article, “4 things you must do before running in Instagram giveaway” they seem to indicate that giveaways can be very successful within the Instagram environment. And maybe that's a good thing if you want to grow your brand. But you also must realize that it won't help you outside of Instagram.

So, I would like to throw it out to you for your feedback. Do you think Instagram is a good place to do giveaways?
