QR codes for social media and marketing

Creator, campaign and out-of-home use, and what scan rates to actually expect.

• Writing the text next to a QR codeThe words beside a QR code matter more than its design. A stated, specific benefit ("Scan for the wine list") consistently outperforms "Scan me", and a…
• A/B testing QR code placementTwo codes, two parameters, one variable, plus the sample-size honesty most guides skip and a sequential method that works on small print runs.
• One QR code for all your socialsThe hub-page pattern (one printed code, one page listing every profile), and the structural rule about who controls the domain the hub lives on.
• QR code for a creator tip jarPayment rails by region (UPI, PIX, PayNow, EPC, US payment-app links) open amounts, 10–20 cm sizing for a stand, and weatherproofing for the street.
• QR code for a Discord inviteDiscord invites expire after 7 days by default: the trap that kills printed codes. Invite settings for print, vanity URLs, and planning for the join surge.
• QR code for a giveawayEntry mechanics that work, what a printed code cannot enforce (one entry per person, location, deadlines), and the terms-and-conditions discipline.
• QR code for a LinkedIn profileClaim a custom URL, encode linkedin.com/in/yourname, and size it for badges, resumes and slides, plus when a vCard code beats LinkedIn entirely.
• QR code for a newsletter signupPrint-to-email capture that works: a one-field form, a source parameter per placement, the placements with real dwell time, and the GDPR opt-in step.
• QR code for a podcastWhy a QR code on podcast cover art fails the arithmetic, and where podcast codes actually work (promo cards, banners, slides) pointing at one follow page.
• QR code for a WhatsApp groupGroup invite links make fine QR codes until an admin taps "reset link" and kills every printed copy. Link ownership, privacy, and group vs chat codes.
• QR code for a YouTube channelWhere a channel QR code belongs (merch, banners, cards pointing at your @handle URL), and the one case where a code inside a video makes sense.
• QR code for event photo sharingShared-album QR codes for weddings and events: table-card sizing, the privacy decisions to make before the day, and how long the album link survives.
• QR code for your Instagram bioHow to put your Instagram profile in a QR code for packaging, posters and cards: the URL format, the size arithmetic, and when to skip Instagram entirely.
• QR codes at trade showsYour own lead-capture codes beat rented badge scanners on speed and ownership, per-station attribution, offline vCards, and booth sizing numbers.
• QR codes for social media: what works and what is absurdQR codes bridge print and packaging to social profiles, and are useless inside a feed viewed on the same phone. A per-placement guide to what works.
• QR codes for webinar signupSlide codes sized for the back row, the photograph-then-scan behaviour audiences actually have, and the calendar step that turns signups into attendees.
• QR codes in direct mailMail is read at a table with a phone nearby: ideal QR territory. Per-recipient codes, postcard vs letter placement, and postal discount programmes.
• QR codes in influencer campaignsPer-influencer codes on merch, inserts and meet-up signage attribute offline reach person by person, plus disclosure norms and measurement honesty.
• QR codes in out-of-home advertisingPlacement physics decides OOH scanning: a dwell-versus-distance table from bus shelters to motorway billboards, with the sizes each placement demands.
• QR codes in print advertisingMagazines and newspapers are friendly territory for QR codes, if you stay out of the gutter, size for arm's length, and tag each publication for measurement.
• QR codes in Reels and TikToks, usually the wrong toolShort-form video is watched on the phone that would scan the code. The three real exceptions, and the size and duration numbers if you go ahead anyway.
• QR codes in TV adsWhat Coinbase's 2022 Super Bowl QR proved about TV codes: the size and duration physics, second-screen behaviour, and load-planning the destination.
• What scan rate should you expect?Why every published "average QR scan rate" is unverifiable marketing, what actually predicts scans, and how to get an honest number for your own campaign.
