The short version: A social media contest only grows your audience if the entry mechanic filters for people who want what you sell, not people who want a free iPad. That means asking for something more than a follow and a tag, capturing emails as the real prize, and having a plan for day 31, not just day one of the giveaway.
I ran my first big giveaway in 2015. Follow, tag three friends, share to your story, done. Simple mechanic, decent prize (a bundle of marketing books and a one-hour strategy call with me, worth about £400), and it worked beautifully on paper. I picked up 3,200 new followers in four days. I felt clever.
Eighteen months later I went back and checked the data. Fewer than 200 of those 3,200 accounts had ever liked, commented on, or clicked anything I’d posted since. Most of them had followed for the tag mechanic, done what their friend asked, and never thought about my account again. Some had already unfollowed. That contest grew a number. It did not grow an audience.
That’s the bit almost nobody tells you when they write “how to run a contest” posts: a follow-to-win mechanic is a follower acquisition tactic, not an audience growth tactic, and the two are not the same thing. Audience growth means more people who will buy from you, read your emails, or hire you. Follower growth just means a bigger number on a page nobody except you looks at.
Why most contest advice grows the wrong number
The standard contest playbook is everywhere: pick a prize, ask people to follow, like, tag friends, and share. It’s easy to run, easy to promote, and it does produce a spike. Instagram and TikTok both reward the spike in the algorithm short term, so the vanity metrics look great in your weekly report.
The problem is the incentive structure. When the only thing someone has to do to enter is tag two mates, you’re not filtering for interest in your brand at all. You’re filtering for people who like winning things, which is a different, much larger, much less useful audience. Contest researchers have found engagement rates on giveaway-acquired followers typically sit well below the account average within three months, and my own experience matches that closely. If your account normally gets 4% engagement and your giveaway followers are sitting at 0.3%, you haven’t grown your audience. You’ve diluted it.
The mechanic that works
The fix isn’t complicated, but it does mean giving up some of that easy viral spike. Build the entry mechanic around something that requires genuine interest, and capture an email address as part of it, not just a platform follow.
- Ask for a specific answer, not a generic tag: “Comment with the biggest marketing mistake you made last year” filters for people who think about marketing, not people who think about winning.
- Route entries through a landing page that collects an email, not just a comment. A follow can be undone in one tap. An email address on your list survives even if the person unfollows you next week.
- Make the prize relevant to your actual offer. Giving away an iPad grows your audience with people who want iPads. Giving away three months of your course, a done-for-you template pack, or a strategy session grows your audience with people who want what you sell.
- Cap the entry window at 5 to 7 days. Longer than that and momentum dies; shorter than that and word of mouth (which drives most of the good entries) doesn’t have time to spread.
When I re-ran a version of this a few years later, prize was a bundle of my own consulting time plus templates, entry required answering a question and dropping an email on a landing page, I got roughly a tenth of the raw entries compared to the 2015 tag-and-share version. But six months later, over 40% of those entrants were still opening my emails, and I closed two paying clients directly from that list. Fewer numbers, far more useful ones. If you want the fastest way to set this kind of contest up without building a landing page from scratch, there’s a solid rundown of social media contest tools that handle the entry form, the email capture, and the winner selection for you.
Step by step: running one
Here’s the actual process I’d use if I were setting one up this month.
- Step 1: Pick a prize that only your ideal customer wants. Not a generic gift card. Something that a random prize-hunter would shrug at but your actual audience would fight for.
- Step 2: Decide the one action you need. One meaningful action beats five easy ones. A qualifying comment or an email signup, not a checklist of five platform actions.
- Step 3: Build the entry point. A simple landing page with a form, connected to your email tool. This is also where treating your online community as an asset pays off, because your existing engaged followers become the ones sharing the contest for you, unprompted, which is far more credible than an ad.
- Step 4: Set clear rules and a fixed end date. Write down eligibility, how the winner is picked, and when they’ll be announced. Post this once, pin it, and stop worrying about it. If you’re running the contest alongside other campaigns, a simple board in something like monday.com to track entry dates, promotion posts, and the announcement keeps it from slipping while you’re also doing your day job.
- Step 5: Promote in three waves. Launch day, midpoint reminder, final 24 hours. The final 24 hours consistently produces the biggest entry spike because urgency finally kicks in.
- Step 6: Announce publicly and follow up privately. Announce the winner on the platform for social proof, then email every entrant, winner or not, thanking them and offering something small, a discount code, a free download, anything that keeps the relationship going past the contest.
- Step 7: Segment and nurture. Tag contest entrants separately in your email list and send them a short welcome sequence over the following two weeks. This is the step almost everyone skips, and it’s the one that turns a contest spike into an actual newsletter audience you can sell to for years.
What to measure (and stop measuring)
Follower count is the vainest metric on the list and I’d stop reporting it as a success measure entirely. What matters instead:
- Cost per qualified entry, meaning entries that included a real email or a genuine answer, not per raw entry.
- Engagement rate of the new followers 30 and 60 days after the contest ends, compared to your existing average.
- Email open rate for the contest segment versus your general list, at the 30 day mark.
- Actual sales or bookings traceable back to the contest list within 90 days.
That last one is the number that convinced me contests were worth doing again. Two clients from one giveaway, worth roughly £6,000 in fees, off a list of about 340 qualified entries. That’s a return most paid ad campaigns would struggle to match, and it came from a contest that on the surface looked much smaller and less impressive than my 2015 one.
The uncomfortable bit nobody puts in the contest checklist
Here’s the part that stings a bit. If your contest is well designed, filtering for real interest, requiring a real answer, tied to a real prize, most of your entries will come from people who already follow you or heard about it from someone who does. A well-run contest doesn’t manufacture a new audience out of nowhere. It concentrates and rewards the audience you’ve already built, and pulls in their close network. If your existing audience is small or disengaged, a contest will expose that rather than fix it. I’ve watched business owners run beautifully designed giveaways to an audience of 400 mostly inactive followers and wonder why they only got 30 entries. The contest wasn’t the problem. The quiet audience underneath it was.
So the honest sequencing is this: build a bit of real engagement first, even a modest one, before you spend a prize budget trying to force growth. A contest is a multiplier, not a starting engine.
Turning the spike into something that pays
The entire point of doing this well is that a contest audience, handled, becomes a revenue audience. That’s true whether you’re selling consulting, a course, or building a media business off content. If you’re building toward the latter, worth reading how creators turn an audience into income in this piece on how to make money blogging, because the segmentation and nurture principles are identical to what you should be doing with contest entrants. Grow the list, prove you’re useful before you ask for anything, then make the offer.
I still run contests occasionally. I just stopped running them for the number on the follower count and started running them for the number in the bank account three months later. Both matter less to my ego and both are a lot more honest about whether the contest worked.
Frequently asked questions
Do social media contests grow followers long term?
Rarely, if the mechanic is just follow-tag-share. Most followers gained that way disengage or unfollow within weeks. Contests grow long term audience only when the entry requires real interest, such as answering a question or handing over an email, not a one-tap follow.
What’s the best prize for a small business contest?
Your own product, service, or time, not a generic gift card or gadget. A prize only your ideal customer wants filters out prize-hunters and attracts people who might buy from you later.
How long should a social media contest run?
Five to seven days works best for most platforms. Long enough for word of mouth to spread through tags and shares, short enough that urgency stays high and you don’t lose momentum halfway through.
Should I collect emails during a social media contest?
Yes, always. A follow can vanish the moment the contest ends, but an email address on your own list survives platform changes, algorithm shifts, and unfollows, and it’s the asset that turns a contest into future sales.
