How Short Links, QR Codes & Campaign Tracking Actually Work
Reference guides, not marketing copy — the real mechanism behind each topic, written to be useful whether or not you ever use PocoLink.
What Is a URL Shortener and How Does It Work?
The mechanism behind every short link is simpler than it looks: a lookup and a standard HTTP redirect. Here is exactly what happens between a click and a destination, including the status-code details that actually matter.
Understanding QR Codes: A Practical Guide
A QR code is a grid of black and white squares that encodes data directly — no server required to read it. Here is how the format actually works, why some codes fail to scan, and how to design one that works reliably in print.
How to Track Marketing Campaigns Using UTM Parameters
UTM parameters are five specific query-string fields, standardized by Google Analytics, that tell your analytics exactly where a visitor came from. Here is what each one does, how to use them without breaking your own data, and when a short link should carry them instead.
How to Create and Manage Short Links
Creating a short link takes a few seconds. Managing it well — picking a destination, naming it sensibly, and knowing when to retire it — is what determines whether it's still useful six months later.
Smart Links and Mobile App Deep Linking Explained
Deep linking and device-based routing solve related but different problems. One tries to open a destination inside a native app; the other sends different visitors to different destinations. Knowing which is which avoids promising a link something it can’t actually do.
How to Analyze Link Performance
A rising click count feels like good news, but on its own it answers almost nothing. Four dimensions — time, device, geography, and referrer — read together are what actually turn link analytics into a decision.
URL Shortening and Online Security
A short link is opaque by nature — you can’t read where it goes before clicking, which is exactly why phishing campaigns find shorteners convenient. Here is what a responsible shortener can and can’t protect against, and how to evaluate any link before trusting it.
QR Codes for Small Businesses
The technical side of QR codes is covered elsewhere — this is the practical side: the specific places a small business sees real, measurable value from one, and the ones where a code is just clutter.
How to Create Trackable Links for Social Media
One link shared identically across five platforms tells you nothing about which one actually worked. A small amount of naming discipline per platform is what turns vague engagement into a real comparison.
Understanding Website Referral Traffic
Referrer data is one HTTP header, sent voluntarily by the visitor’s own browser — which is exactly why it’s unreliable in specific, predictable ways. Knowing when it breaks is what keeps a "direct traffic" number from being misread.
