Google Review Button Widget

How it works

Google gives every business listing a Place ID - a long code that usually begins ChIJ - and Business Profile owners can also copy a short review link of the form g.page/r/<code>/review. The widget accepts either, or a full search.google.com/local/writereview link you already have. A Place ID is checked against the shape Google uses (letters, digits, hyphen and underscore only) and turned into https://search.google.com/local/writereview?placeid=<id>, the address that opens the star-and-text review dialog on top of your listing; a short link is kept exactly as Google issued it, minus any tracking query. Any other host, a look-alike such as g.page.example.com, credentials, ports, quotes or script are refused, and the builder says so instead of drawing a broken button. The card layout adds your business name, a short thank-you and a note that reviews are public. The QR layout encodes the same address at error correction level M with the vendored qr-code-styling engine, loaded only for that layout; Print sends a 4 x 6 inch image of the card to the printer without the rest of your page, and Download PNG saves the same 300 dpi image.

Method

• Place ID accepted when it matches ^ChIJ[A-Za-z0-9_-]{10,200}$ or the general ^[A-Za-z0-9_-]{16,300}$ shape
• Review address = https://search.google.com/local/writereview?placeid= + encodeURIComponent(Place ID)
• Short link accepted only as https://g.page/r/<4-200 letters, digits, - or _>/review; rebuilt without query or fragment
• writereview links: host must be exactly search.google.com and path /local/writereview; only the placeid parameter is kept
• QR: qr-code-styling 1.8.4, error correction M, #10162b on white; print image 1200 x 1800 px = 4 x 6 in at 300 dpi

Worked examples

Limitations

• Shows no rating, review count or review text - none is available without the paid Places API.
• Cannot check that a Place ID belongs to your business; open the button once to confirm the right listing appears.
• The QR card prints at 4 x 6 inches; for other sizes use Review QR Code, which also handles Trustpilot, Yelp and other sites.
• Opening the review form requires the visitor to sign in to a Google account.

Where publishers use it

• A cafe or salon adding the QR card to a laminated sign by the till, so customers can review from their phone while they wait for change
• A plumber or electrician putting the plain button at the end of the job-complete email and on the invoice page of their website
• A dental or physiotherapy practice placing the thank-you card on its after-appointment page, next to the booking confirmation
• A shop with several branches making one button per branch, each with its own Place ID, on the store-finder pages
