Black Friday Social Media Post Ideas for Online Shops

The short version: most Black Friday social posts fail because they all say the same thing in the same way on the same day, so the fix is to spread your announcements across a two week run, lead with specifics instead of hype, and build at least one post around a real customer problem rather than a discount percentage. Below is a full set of post ideas, a worked example for a small shop, and the posting order I'd use.

Why most Black Friday posts underperform

Here's the uncomfortable bit nobody wants to say out loud: your Black Friday post is competing against roughly every other shop you follow, all posting the exact same "25% OFF EVERYTHING" graphic on the exact same Friday. The algorithm doesn't care that your discount is generous. It cares whether people stop scrolling, and a red banner with a percentage sign stopped working as a scroll-stopper years ago.

The shops that do well on Black Friday aren't the ones with the biggest discount. They're the ones who posted something specific enough that a stranger could picture themselves using the product. "30% off" tells nobody anything. "Save £18 on the hand cream your mum keeps stealing from your bathroom" tells a story in nine words.

The post ideas, grouped by job

Countdown and teaser posts (start 10 to 14 days out)

• A "what's coming" post showing three products wrapped in brown paper, captioned "one of these is 40% off on Friday, guess which one"
• A behind the scenes post of you or your team packing boxes, captioned: "we're prepping for Black Friday and I will not lie, it's chaos here"
• A poll or question sticker on Stories asking followers which product they'd want discounted, then discounting it
• A "last year's Black Friday sold out in 6 hours" post if that's true, with a screenshot of your old order notifications blurred for privacy

Launch day posts

• A carousel with one slide per product, each showing the before price, after price, and one line on who it's for ("for the person who loses their keys daily")
• A short video (15 to 30 seconds) of you picking up three items and saying the discount out loud, filmed on a phone, no studio lighting needed
• A "bundle only available today" post, bundling a slow-moving product with a bestseller so it shifts stock instead of just margin

Mid sale posts (day 2 to 4)

• A reviews post, screenshotting three real customer comments about the specific products on sale
• A restock or "only 12 left in size M" post, which works because it's true and specific, not because it's manufactured urgency
• A staff pick post: "our customer service lead swears by this one, here's why"

Last chance posts (final 24 to 48 hours)

• A plain text graphic, no product photo, just "sale ends at midnight tonight, here's what's still in stock" with a link
• A Stories countdown sticker set to your actual end time
• A "we extended it by mistake and now it's really ending" type post, only if true, because faking urgency and getting caught in the comments is worse than no urgency at all

A worked example: a candle shop with 4,200 followers

Say you run a small candle shop on Instagram with around 4,200 followers and an average post reaching maybe 600 to 900 accounts. Here's a realistic 10 day plan:

• Day 1 (10 days out): teaser post, three candles wrapped, "guess which scent is 35% off Friday" caption, Stories poll
• Day 4: behind the scenes reel of restocking shelves, captioned about how much stock you've ordered
• Day 8: launch day carousel, one slide per candle, before and after price, one line per scent on mood or use ("for the 9pm wind down")
• Day 9: reviews post pulling three real comments from past customers about the specific scents on sale
• Day 10: last chance plain text post, no photo, just the facts and a link, posted at 6pm when evening scrolling peaks

Ten posts is roughly what a small shop can sustain without it feeling like spam, and spacing them this way means you get three separate chances to catch three separate groups of people, rather than one chance to catch everyone at once.

The step-by-step for building your own set

1. List every product going on sale and write one honest sentence about who buys it, not who you wish bought it
2. Pick your discount structure first (flat percentage, bundle, or free gift over a spend threshold) because the post format follows the offer, not the other way round
3. Draft your last chance post before anything else, because it's the one that converts the most and the one people write laziest under time pressure
4. Batch your graphics in one sitting rather than daily, which is far easier if you already use a real social media calendar to slot them in
5. Use free AI tools to generate the sale banners rather than paying a designer for ten graphics you'll use for one week a year, and there's a full rundown of where to make Black Friday sale banners for free

Captions that work (and ones that don't)

"Up to 50% off" is a caption I'd avoid. It's vague, it's been used by every shop for a decade, and it makes people suspicious that "up to" means one unpopular item is 50% off and everything else is 10%. Compare it with "£12 off our bestselling tote, no code needed, ends Sunday midnight." That's one sentence, it's specific, and it answers the three questions a buyer has: what's off, how much, and when it ends.

If you sell food, homeware, beauty, or anything with a personal use case, write captions around the moment someone uses the product rather than the product itself. A bakery might post "the loaf that disappears before breakfast is 20% off this week" instead of "sourdough 20% off." If you want a shortcut for generating that kind of specific, person-first copy at speed, there's a set of ChatGPT prompts built for food business owners that adapt well to any product-led shop.

What to track (without paying for extra tools)

You don't need a paid analytics dashboard to know if your Black Friday posts worked. Check saves and shares on each post, not just likes, because saves correlate far more strongly with purchase intent. Check link clicks on your Stories link sticker day by day. Compare your busiest posting day against your actual sales day in your shop platform's own order data. If you want the full method, I've written up how to measure social media success without a paid analytics tool, and it covers exactly this kind of short-burst campaign tracking.

One more thing worth doing before you plan any of this: spend 20 minutes on Ahrefs' free tools checking what search terms people use around your products in November. It's free, permanently, not a trial, and the keyword data will tell you whether to lean your captions toward "Black Friday" or "Cyber Monday" depending on which one your actual customers search for. There's a full explainer on Ahrefs' free tools and why there's no need for a trial.

The bit most shops get wrong

The uncomfortable truth is that posting more on Black Friday week often performs worse than posting less but better. I've seen shop accounts post six times in one day during their sale and watch reach drop with every extra post because the algorithm reads repeated same-day posting as spam behaviour, not enthusiasm. Pick your three or four strongest moments (teaser, launch, mid sale proof, last chance) and make each one count rather than filling every slot in your calendar out of nervousness.

Also worth saying plainly: discounting everything equally is usually a mistake. If a product already sells well at full price, discounting it hard just gives away margin on sales you'd have made anyway. Save your deepest discounts for slow stock and bundle your bestsellers with that slow stock instead, so the post does double duty, clearing shelves and protecting margin at the same time.

Frequently asked questions

How many Black Friday posts should an online shop do?

For most small shops, 8 to 12 posts spread across 10 to 14 days works better than a cluster of posts on the day itself, because it catches different segments of your audience at different moments rather than relying on one post to do all the work.

What's the best time to post the final "sale ends" post?

Early evening, around 6pm to 8pm local time, tends to work well because it catches people scrolling after work with enough hours left in the day to buy, rather than posting it at midnight when the sale is already over.

Should every Black Friday post include a discount percentage?

No. Specific pound or dollar amounts and specific use cases usually outperform vague percentages, because "£15 off" or "save on the scarf everyone asks about" gives people a clearer reason to click than "up to 40% off" does.

Do I need paid ads alongside organic Black Friday posts?

Not necessarily, but a small boost budget behind your best-performing organic post (the one with the highest saves and shares in the first few hours) usually stretches further than spreading a budget evenly across every post you publish that week.
