QR code review funnels: best practices that actually convert

A QR code review funnel has three parts: the code itself, the landing page it opens, and the path from that page to a published Google review. Get all three right and you can see scan-to-review rates well above 30–40%. Get one wrong and even a well-placed code converts in the low single digits.

The QR code: size, contrast, placement

• Size: at least 2.5cm (1 inch) square for a table tent or receipt, larger for anything scanned from more than arm's length, like a wall poster.
• Contrast: dark code on a light background scans far more reliably than the reverse, especially in bad lighting.
• Placement: somewhere a customer naturally looks while paying or leaving — the receipt, the counter next to the card reader, or a table tent — outperforms a generic poster on a far wall.
• One clear call to action: "Enjoyed your visit? Scan for 30 seconds to leave a review" beats a bare QR code with no context every time.

The landing page: what actually converts

The page a scan opens is doing the real work of convincing someone to follow through. High-converting landing pages share a few traits:

• Loads instantly on mobile data, no heavy images or slow redirects.
• Shows the business name and logo immediately, so customers trust it's legitimate.
• Offers a short, specific, editable review suggestion rather than a blank box — most people will lightly edit good starting text rather than write from nothing.
• One clear, large button to continue to Google — not a menu of options.

The handoff to Google

The single biggest conversion killer in QR review funnels is a broken or generic link — one that takes customers to a search results page instead of directly to the review form for your specific Business Profile. Test your link on both iOS and Android before printing anything at scale; behavior can differ between the Google Maps app and mobile browser.

Multiple locations, multiple codes

If you have several tables, counters, or branches, use a distinct QR code per placement rather than one generic code everywhere. This is the only way to see which specific placement is actually driving reviews — table 4 might convert at 3x the rate of table 12, and you won't know unless each has its own tracked code.

Common mistakes to avoid

• Printing codes too small to scan reliably from a normal arm's length.
• Linking to your homepage instead of directly to the review flow — that's an extra step most customers won't take.
• Using pre-written review text that isn't clearly labeled as an editable suggestion — this risks looking like fake reviews and violates most platforms' policies if presented as final text customers just submit unedited at scale.
• Never checking your own analytics — a funnel you don't measure is a funnel you can't improve.
