What is URL Shortening? 5 Reasons to Use Short URLs in Marketing

Have you ever needed to share a link, but it was so long that it took up your entire Instagram caption, got cut off on Zalo, or looked unprofessional on a namecard? That is when you need a URL shortener.

This article will explain what URL shortening is, how it works, and 5 compelling reasons why you should start using it today.

What is a URL shortener?

URL shortening is the process of converting a long URL into a shorter one that still directs to the same destination page. For example:

• Original URL: https://metoolzy.com/blog/cach-tao-qr-code-mien-phi-huong-dan-chi-tiet?utm_source=facebook&utm_medium=post&utm_campaign=launch2026
• Short URL: https://mtz.link/qr-guide

When someone clicks on the short URL, the system will automatically redirect (301 redirect) to the original URL. This process happens almost instantly (under 50ms), so users won’t notice the difference.

How a URL shortener works

1. You enter the original URL into the shortening tool
2. The system generates a unique short code (for example: qr-guide) and saves the mapping in the database
3. When someone visits the short URL, the server looks up the short code → finds the original URL → redirects
4. At the same time, the server records information: click time, IP, device, and traffic source

5 reasons you should shorten links

1. Significantly increase Click-Through Rate (CTR)

Research from Rebrandly (2024) shows that short URLs have a 39% higher CTR compared to long URLs on social media. The reason is simple: users trust and are more willing to click on a neat link.

A visual comparison:

• ❌ https://example.com/products/category/electronics/smartphones/iphone-15-pro-max?color=blue&storage=256gb&ref=homepage_banner_click_2026
• ✅ https://mtz.link/iphone15

Which link would you click? The answer is obvious.

2. Tracking and measuring campaign effectiveness

This is the most important reason for marketers. Each short link acts as a separate tracker, providing data:

• Total clicks and unique clicks
• Traffic source: Facebook, Zalo, Email, QR code scan
• Device: Mobile vs Desktop, iOS vs Android
• Geolocation: Know which province/city your customers are from
• Click time: Identify the golden hours of your target audience

Instead of creating many complex UTM parameters, you just need to create separate short links for each channel: mtz.link/sale-fb, mtz.link/sale-zalo, mtz.link/sale-email.

3. Suitable for all platforms — especially mobile

Each platform has its own limits:

Platform	Limit	How does a Short URL help?
Twitter/X	280 characters	Saves space for content
Instagram Bio	1 single link	Short links are easier to remember
Zalo/Messenger	Preview gets cut off if the URL is too long	Displays neatly and professionally
SMS Marketing	160 characters	Every character is precious
Printing (brochure, namecard)	Limited space	Easy to read, easy to type manually

4. Build your brand with Branded Short URLs

A short URL with a custom domain helps increase brand awareness. Instead of using a generic domain (bit.ly/abc123), you can use your own domain:

• Nike: swoo.sh/just-do-it
• The New York Times: nyti.ms/breaking
• Metoolzy: mtz.link/your-campaign

Branded short URLs have a CTR 34% higher than generic short URLs (source: Bitly, 2024). Users see the brand name right in the URL → trust it more → click more.

5. Flexible management and control

With short links, you get an extra layer of control that regular URLs don’t have:

• Set expiration dates: Link automatically expires after date X — perfect for flash sales, limited-time promo codes
• Limit clicks: Only allow N visits — suitable for exclusive offers
• Password protect: Require a password to access — used for internal content or confidential documents
• Edit destination URL: Change the destination page without creating a new link — extremely useful after printing QR codes

When to use and not use short links?

Should use

• Sharing on social media, SMS, email marketing
• Printing on materials (namecards, posters, packaging)
• Combining with QR codes (short URL → simpler QR code)
• Tracking marketing campaigns
• Sharing links in presentations, videos

No need to use

• Internal links on a website (affects SEO if using redirect)
• Backlinks from other websites (search engines need to see the original URL)
• Links in source code or API
