In Part 1, we covered everything you need to plan, create, and promote an Instagram giveaway for maximum reach. Now comes the part most people get wrong: the execution, the follow-through, and the conversion. This is where giveaways either pay off or fall flat.
Let's pick up where we left off.
7The Biggest Mistakes People Make
After seeing thousands of Instagram giveaways, these are the errors that kill results most often.
Picking an irrelevant prize. An iPhone giveaway will get you thousands of entries from people who will never buy from you. A curated bundle of your own products will get fewer entries, but the people who enter are your actual target customers. Always choose relevance over raw value.
Running the giveaway too long. Momentum peaks in the first 48 hours. After seven days, engagement drops off a cliff. Keep it short, keep it exciting, and create urgency with a clear deadline.
Making entry rules too complicated. Every additional step you add to your entry requirements — follow this account, like these three posts, tag five friends, share to your story, sign up for our newsletter — reduces participation dramatically. Three steps is the maximum. Two is ideal.
Not verifying entries. If your rules say "must be following to win," you need to actually check that the winner is following you before you announce them. Nothing damages credibility faster than a winner announcement followed by "actually, they weren't eligible."
Picking winners manually. This is the mistake that trips up the most people. When you have 200, 500, or 1,000+ comments, scrolling through them to verify entries and randomly select a winner is painful. You miss duplicate entries, you can't filter out spam comments, and if someone questions your selection, you have no proof it was random.
Not announcing the winner publicly. If you pick a winner and only tell them via DM, everyone else assumes the giveaway was fake. Always make a public announcement — a post, a story, or both. This builds trust and trains your audience to enter your next giveaway because they can see that real people actually win.
No follow-up strategy. The giveaway ends, you gain 2,000 followers, and then you go back to posting the same content as before. Within two weeks, half of those followers have unfollowed or gone silent. You need a plan for what happens after the giveaway — and we'll cover that in the next section.
8How to Pick a Winner Fairly (and Prove It)
Fairness isn't just a nice-to-have — it's the foundation of trust that makes people want to enter your future giveaways. If your audience suspects the winner was hand-picked or that the selection wasn't truly random, they'll stop participating. And once that trust is broken, it's very hard to rebuild.
The gold standard is to use a tool that pulls all eligible comments, filters out entries that don't meet your rules (didn't follow, didn't tag enough friends, duplicate comments from the same person), and then performs a verifiably random selection from the remaining pool.
This is where trying to do it manually falls apart. With a few dozen entries, you might be able to scroll through and pick someone. But once you hit a few hundred comments — let alone thousands — it becomes impossible to ensure every entry is verified and the selection is truly unbiased. You'll inevitably miss entries, count duplicates, or unconsciously gravitate toward names you recognize.
This is exactly the problem PromoHive was built to solve. You connect your giveaway post, and PromoHive automatically imports all comments, filters them based on your entry rules (must be following, minimum tags, keyword requirements), removes duplicates and spam, and picks a verified random winner with a single click. Every step is logged, so you have a transparent record you can share with your audience. The free plan supports giveaways with up to 500 comments — more than enough for most small to mid-size accounts — and there's no credit card required to get started.
Whichever method you use, document your winner selection process and share it publicly. A simple story or post saying "We received 847 eligible entries and used a random selection tool to pick our winner — congratulations @username!" goes a long way toward building credibility.
9After the Giveaway: Converting Followers into Customers
The giveaway brought in hundreds or thousands of new followers. Now what? This is the phase where most accounts drop the ball — and it's actually the most important part of the entire process.
Announce the Winner Publicly
Post a congratulatory story (or post) tagging the winner. This does three things: it proves the giveaway was legitimate, it creates a feel-good moment that people associate with your brand, and it gives you one more engagement touchpoint with your audience. If the winner shares their excitement in their own story, even better — that's free exposure to their followers.
Offer a Consolation Incentive
Within 24 hours of announcing the winner, post a "thank you for entering" message with an exclusive discount code for everyone who participated. Something like "You didn't win this time, but here's 15% off as a thank you for being part of our community." This converts the disappointment of losing into a purchase opportunity, and the time-limited nature of the offer creates urgency.
Double Down on Content Quality
The two weeks after a giveaway are critical for follower retention. Post your best content during this window — valuable tips, behind-the-scenes content, relatable stories, and strong visuals. New followers will decide very quickly whether to stick around or unfollow, and your content quality in this window is what tips the scale.
Analyze and Iterate
After every giveaway, track your key metrics: how many entries did you receive, how many new followers did you gain, what was the follower retention rate after one week and two weeks, how many people used the post-giveaway discount code, and what was the overall engagement rate on the giveaway post compared to your average? Use these numbers to plan your next giveaway — double down on what worked and fix what didn't.
10Giveaway Ideas by Niche
Not sure what to give away? Here are proven giveaway concepts for six popular niches.
A "best sellers" bundle worth $100–200. Include 3–5 of your top products so the winner experiences the range of your store. Great for generating UGC when the winner posts about their haul.
A full routine set — cleanser, serum, moisturizer, and a bonus item. Partner with a complementary brand (makeup + skincare) for a joint giveaway that reaches both audiences.
One month of free coaching, a custom meal plan, or a premium workout program. The winner becomes a testimonial and case study, which is worth far more than the cost of the prize.
A dinner for two, a catering credit, or a "menu tasting" experience. Ask entrants to tag who they'd bring — this naturally drives tags and creates emotional investment in winning.
Signed copies, exclusive merchandise, or early access to upcoming releases. Bookish audiences are highly engaged and love sharing their wins, which creates organic promotion for your work.
A gift card to your store, a free service session, or a VIP experience. Focus your entry mechanics on follows and tags from local accounts — use location-based hashtags to keep reach geographically targeted.
Wrapping Up
Instagram giveaways are one of the highest-ROI growth tactics available to any account — but only when they're planned thoughtfully and executed professionally. The best practices in this guide aren't complicated, but they do require intentionality: choose a relevant prize, keep entry rules simple, promote across multiple channels, pick winners fairly and transparently, and have a clear plan for converting new followers into engaged community members and customers.
The accounts that run giveaways consistently — once a month or once a quarter — build compounding momentum. Each giveaway is easier than the last, the audience grows and becomes more engaged, and the conversion pipeline from follower to customer gets stronger over time.
The most important thing is to start. Your first giveaway doesn't need to be perfect. It just needs to be well-planned, clearly communicated, and fairly executed. Everything else you'll learn and improve along the way.
