maratoolQR code vs UTM builder
A side-by-side comparison of QR Code Generator and UTM Builder.
A QR code is a delivery mechanism: it gets a URL into someone’s phone without typing. A UTM builder is a tracking layer: it appends ?utm_source=…&utm_medium=…&utm_campaign=… to a URL so analytics can attribute the click. They are not alternatives — they are complementary, and the best practice is to combine them.
A QR code on a print poster that opens a UTM-tagged URL is how you measure print campaigns. Without the UTMs, every QR scan looks like direct traffic.
When to use QR Code Generator
Use the QR code generator when the link needs to live in the physical world — posters, business cards, packaging, menus, ads. The QR code is the bridge between print and web.
When to use UTM Builder
Use the UTM builder on every link in any campaign — email, paid ads, partner placements, podcast sponsorships, the QR code above. Without UTMs, GA4 cannot tell whether a visitor came from your spring poster or a random search.
Side-by-side comparison
| QR Code Generator | UTM Builder | |
|---|---|---|
| Purpose | Deliver a URL offline | Track which campaign drove the click |
| Output | Square image (PNG/SVG) | URL with ?utm_… params |
| Read by | Phone camera | Analytics (GA4, Mixpanel, etc.) |
| Works without each other? | Yes — but you lose attribution | Yes — but only on typed/clicked links |
| Right way to use together | QR encodes a UTM-tagged URL | UTM tags the URL the QR encodes |
| Visible to user | Yes — the QR pattern | In the URL bar after redirect |
| Lifespan | As long as the printed material | As long as the URL works |
| Cost | Free to generate | Free to generate |
Bottom line
They are not alternatives — generate a UTM-tagged URL, then put it inside a QR code. Each one alone leaves money on the table.
Frequently asked questions
Should I shorten the URL before generating a QR code?
Optional. QR codes handle long URLs fine, but shorter URLs generate smaller, easier-to-scan codes — useful when print space is tight. Just make sure the shortener preserves the UTMs.
Will GA4 show QR code traffic separately?
Only if you tag with utm_medium=qr (or similar) on the encoded URL. GA4 cannot detect that a click came from a QR scan otherwise — it just sees a normal HTTP referral or "(direct) / (none)".
Do I need utm_term and utm_content?
Source, medium, and campaign are the must-haves. Term is for paid search keywords (often auto-filled by ad platforms); content is for A/B-testing different placements of the same campaign. Skip them if you do not need that granularity.
Can the QR code be regenerated without changing the URL?
Yes — the QR pattern is deterministic from the URL, so regenerating with the same URL produces the same code. To change the destination after the QR is printed, use a redirect URL you control (and put that inside the QR).
