Spin the wheel marketing: the prize table, the rules and the number that tells you it worked

Spin the wheel marketing puts a game of chance in front of an offer: the visitor enters an email address or a phone number, spins a wheel, and lands on a discount, a free item or a second chance. It lifts capture rate because the reward is uncertain and the effort is one click, and it works best where the prize is something the person already wanted. The number that tells you whether it paid is not the spin count and not the capture rate. It is the revenue per address collected, measured ninety days later against the revenue per address from your ordinary signup form. If the wheel brings in three times the addresses at a third of the value, you have bought a bigger list and a smaller business.

The three places a wheel runs

• On the website, as a popup or a slide in panel, usually triggered on exit intent, on a scroll depth or after a set time. This is the version most people mean, and it is the one with the technical caveats further down.
• At an event or trade stand, as a physical wheel or a tablet. The prize is collected at the stand, the data is collected in exchange for the spin, and the conversation is the real prize for the exhibitor.
• In store or on packaging, behind a QR code at the till, on a receipt or inside the box. This version works for repeat purchase and for review collection, because the person has already bought.

The mechanic is the same in all three. What changes is how much the prize can cost you, since a stand prize is handed over once and a website discount can be redeemed by everyone who spins.

Designing the prize table

Most wheels fail at the prize table, not the design. Build it as a short list where every segment has a defined cost and a redemption rule, and where nothing on the wheel is worthless. A segment reading "better luck next time" teaches the visitor the game was fake and costs you the address you just collected.

Segment	Typical use	The rule to attach
Small percentage off	The majority of segments, the workhorse	Minimum order value, single use code, expiry in days
Free delivery	Strong on carts that stall at the shipping line	One address, exclude heavy or oversized items
Free add on item	Clears slow stock and feels bigger than a discount	While stocks last, stated on the wheel
Larger discount	One or two segments, the reason people play	Tighter minimum, shorter expiry
Headline prize	Events and seasonal pushes	Named odds, a draw date and a published winner

Work out the blended cost before launch. Multiply each segment's cost by its share of the wheel, add the expected redemption rate, and compare that figure to your margin. A wheel whose average giveaway exceeds the margin on a first order only pays back if your repeat purchase rate is strong, which is a decision for the finance side of the business, not the design side.

Writing the rules so the promotion stays clean

A wheel is a prize promotion, and the same plain obligations apply as to any giveaway. Write a short terms page, link it from the wheel itself, and cover these points.

• Who may enter, including age and location limits.
• Whether a purchase is required. Charging for an entry turns a promotion into something regulated far more tightly in most countries, so keep entry free.
• The odds, or at least the number of segments and how the result is determined.
• The prize, the quantity available, the expiry and whether it can be combined with other offers.
• What happens to the data: who holds it, what you will send, and how to unsubscribe.
• The promoter's legal name and an address.

Rules differ by country and some sectors have their own restrictions, so take the specifics for alcohol, gambling, finance, medicines and anything aimed at children from a local source before you launch. The structure above is what a buyer and a regulator both expect to find in one place.

The technical side on a website

A wheel is an overlay, and overlays sit in the middle of two things Google has published guidance on. Its page experience documentation asks directly, "Do your pages avoid using intrusive interstitials?" and states that "Core Web Vitals are used by our ranking systems". The practical reading of that guidance for a wheel is a short list of build rules.

• Never show it on first paint, and never on a page arriving from search before the content is readable.
• Reserve the space it occupies so the layout does not jump when it appears, which is what keeps the layout shift metric clean.
• Load the script after the main content, not in the head.
• Make the close button large, visible and the first thing reachable by keyboard.
• Set a cookie so a visitor who closed it is not asked again on the next page, and exclude the checkout entirely.
• Keep it off landing pages used for paid traffic unless you have tested it there, since the overlay competes with the offer you paid for.

What to measure, in order

Metric	What it tells you
Display to spin rate	Whether the offer and the timing are right
Code redemption rate	Whether the prize was wanted, and the real cost of the wheel
Revenue per address at 30 and 90 days	The only figure that settles whether to keep it
Unsubscribe and complaint rate	Whether you collected customers or prize hunters
Repeat order rate of wheel signups	Whether discount habit has been created

Run it as a split test against your existing signup offer for a fixed period, with the same traffic sources on both sides, and decide on the ninety day number. Measuring on the capture rate alone is what makes a wheel look like a triumph for one quarter.

Where wheels go wrong

• Discount habituation. If the wheel is always on, regulars learn to clear cookies and spin before every order. Run it in windows, or restrict it to first time visitors.
• A prize nobody wants. Five percent off a low priced item is not worth an email address. Test one segment with a genuinely useful prize and watch the spin rate move.
• Collecting addresses you cannot mail. Consent has to be explicit and separate from the entry, or the list you built is one you may not use.
• No redemption deadline. Codes without expiry sit in inboxes for a year and then get used in your best trading week.
• Running it on every page. One page type, one trigger, one frequency cap.

Questions about spin the wheel promotions

Is a spin the wheel popup allowed under consumer rules?

A free entry prize promotion with published terms is ordinary marketing in most markets. What draws attention is charging for entry, hiding the odds, or describing a prize that is not available. Keep entry free, publish the terms and honour every code.

Will a wheel hurt my search rankings?

Not if it is built to the rules above. What causes trouble is an overlay that covers content for a visitor arriving from search, blocks the page on mobile, or shifts the layout while loading.

What spin rate should I expect?

Judge it against your own current signup form rather than a published benchmark, because the figure moves with traffic source, device and prize. The useful comparison is your form last month against the wheel this month on the same traffic.

Can the wheel be weighted?

Segments are routinely weighted so the headline prize is rarer than the common one. Say that the odds differ by segment in the terms rather than implying every slice is equally likely.

Does this work for a service business?

It works where the prize converts into a booking: a free first visit, a survey at no charge, an upgrade on a package. It works poorly where the purchase is considered and infrequent, because a discount game sits oddly next to a high value decision.

Should the wheel collect a phone number?

Ask for one field only, and make it the channel you actually use. A wheel that asks for name, email, phone and birthday loses most of the lift the game created.

What a wheel campaign leaves behind, and who reads it afterwards

A wheel runs for a few weeks and then stops, but its residue stays online: the offer landing page, the terms, the posts promoting it and the reviews that mention a prize. That residue is what an assistant reads when somebody asks whether a brand runs promotions, or which shops in a category discount regularly. The answer that comes back can be flattering or it can describe a business as discount led for years after one campaign, because a model summarising your brand works from whatever text about you is easiest to find. It is worth knowing which version of that sentence is being produced about your brand before you plan the next promotion. Checking it takes minutes, and it is the single job AI Knows Us does: it reads those brand sentences back to you, one from each assistant, so you can see whether a quarter of discounting has turned into your description.
