In the digital age, businesses cannot focus solely on online advertising channels and ignore the potential of offline advertising such as flyers, banners, standees, billboards, display booths, etc. However, the biggest challenge with offline campaigns is the difficulty in measuring effectiveness. It is unclear whether customers are interested, whether they interact, and whether it leads to purchasing behavior.
This article will guide you on how to combine Google Form and QR code to both measure the effectiveness of offline advertising campaigns and optimize customer interaction rates, helping you better understand what customers think so you can adjust your communication strategy more effectively.
Why is offline advertising still important?
Although digital marketing is dominant, offline advertising remains an indispensable channel in many industries:
-
Physical brand presence: Posters and billboards at crowded locations help reinforce brand recall effectively.
-
Reaching customer groups with limited online access: For example, the elderly or consumers in areas where the internet is not yet widespread.
-
Creating direct effects: Event booths, roadshows, and sampling create real-life experiences for customers.
However, the biggest problem is the inability to track how many people have interacted with the advertisement and whether the campaign is truly effective.
Combining Google Form + QR code for measurement
1. Google Form – A simple, free data collection tool
Google Form allows you to create survey forms, registration forms, feedback forms, etc. in just a few minutes and completely free of charge. The data will automatically be sent to Google Sheets, making it easy for you to analyze and generate statistics.
2. QR Code – The bridge between offline and online
By printing QR codes that link to Google Forms on offline advertising materials, you create an instant interaction channel with customers without the need for sales staff. With just one scan, users can fill out feedback forms, join mini-games, receive promotional codes, register information, etc.
Guide to creating a Google Form to measure offline advertising campaigns
Step 1: Define measurement objectives
What do you want to measure from your offline campaign?
-
How many people saw the poster?
-
How many people scanned the QR code and responded?
-
Where did customers hear about the product?
-
Do they remember the content of the advertisement?
-
Are they willing to leave their information or register to receive promotions?
Step 2: Create a Google Form suitable for your objectives
Some suggested questions:
-
Where did you see our advertisement? (Multiple choices: flyer, poster, bus, booth, etc.)
-
What made you scan this QR code?
-
Which service/product are you interested in?
-
Rate the design/scale/attractiveness of the advertisement (1–5 stars).
-
Would you like to receive more offers/promotions via email? (Enter your email)
Step 3: Generate a QR code linking to the form
After completing your Google Form:
-
Click “Send” > select the link icon > shorten the link.
-
Use QR code generator websites such as:
-
Customize the QR code with your brand colors or add your logo.
Optimizing customer interaction rates through QR codes
1. Design a prominent QR code in the layout
-
Do not place the QR code too small or in a hidden position.
-
Suggestion: place the QR code in the center or at the bottom of the poster with an easy-to-read line such as: “Scan the code to receive an instant offer!” or “What do you think about this ad? Scan the code to share!”
2. Create motivation to scan the code
-
Give vouchers or discount codes after filling out the form.
-
Allow code scanners to participate in a lucky draw.
-
Lead to an interesting quiz mini-game.
3. Track and analyze data from Google Form
-
Google Sheets lets you know the time, device, and content of user responses.
-
Combine with UTM or hidden information in the URL (for example:
?source=poster_BenThanh) to identify the specific advertising source.
Common mistakes to avoid when implementing
-
QR code does not work: The link is too long, broken, or the Google Form is not public => test thoroughly before printing.
-
Lack of clear CTA in design: No call-to-action, so customers do not understand why they should scan.
-
Form is too long: Passersby do not have enough time to answer 10 questions.
-
Not checking data regularly: Collecting feedback without compiling or measuring is pointless.
Offline advertising will no longer be vague in terms of effectiveness if you know how to integrate simple technology like Google Form and QR code. Tracking feedback, creating interaction incentives, and optimizing campaigns not only help you save budget but also provide valuable insights from consumers.
