Link Analytics That Actually Make Sense: Dub.co vs. Bitly vs. Short.io

You're running a campaign. Traffic's flowing. But when you check your link analytics, you get nothing but a vanity metric and a bill for $35/month.

This is the Bitly experience in 2024.

I've been there. You set up a shortened link, share it across channels, and then... you can't tell which traffic source converted, what the click-through rate actually means, or whether your campaign ROI is positive. The platform makes money from your uncertainty. Meanwhile, better tools exist that give you everything—for free.

After testing Bitly, Short.io, and Dub.co across three campaigns, I switched to Dub.co and haven't looked back. Here's what I learned.

Why Link Analytics Matter (And Why Bitly Fails)

Shortened links are deceptively important. They're your data collection points. Every click is a potential signal: which channel works, which content resonates, which audience buys.

But Bitly's free plan gives you almost nothing. No click geography. No UTM parameter visibility. No API access. Want those features? That's $35/month—more if your team is larger.

For most marketers, that's a non-starter. You don't pay $35/month to understand what you should already know.

The Comparison

Here's what I found testing each platform:

Feature	Dub.co	Bitly	Short.io
Free Plan Cost	$0	$0	$0
Custom Domain	✓ (included)	✗ (paid)	✓ (paid tier)
Full Analytics	✓ (free)	✗ (limited)	✓ (limited free)
API Access	✓ (free)	✗ (paid)	✓ (limited)
QR Codes	✓ (branded)	✓ (basic)	✓ (basic)
Webhooks	✓	✗	✗
Team Collaboration	✓	✓	✗
Monthly Cost (Full Features)	Free	$35+	$25+

Dub.co wins on price, but that's not the whole story. Let me show you the practical difference.

How Dub.co Actually Works

I set up a campaign with an affiliate link (I'm using Dub.co myself for link management). Here's what I got instantly:

• A custom domain link: mysite.link/campaign-name
• Click tracking by geography, device, browser, and referrer
• UTM parameter preservation (I can see exactly what my tracking actually caught)
• A branded QR code to print on materials
• Webhook notifications when someone clicks (I built a Slack integration)
• Full API access to automate everything

The API is the killer feature. With Bitly's paid tier, you get API access. With Dub.co's free tier, you also get it. Here's an example:

curl -X POST https://api.dub.co/links \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://example.com/page?utm_source=twitter",
    "domain": "mysite.link",
    "key": "campaign-123",
    "expiresAt": "2024-12-31"
  }'

That's it. You create shortened links programmatically. You can batch them. You can set expiration dates. You can track which links perform best, in real-time.

Bitly makes you pay $99/month for that. Short.io charges $25/month and still limits your API calls.

Building a Tracking System

Here's a practical example. Say you're running ads on three platforms and want to know which converts best.

With Dub.co's API, you can create links for each platform in a loop:

const platforms = ['twitter', 'linkedin', 'email'];

for (const platform of platforms) {
  const response = await fetch('https://api.dub.co/links', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.DUB_TOKEN}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      url: `https://myproduct.com/checkout?utm_source=${platform}`,
      domain: 'track.mysite.com',
      key: `promo-${platform}`,
      trackConversion: true
    })
  });

  const link = await response.json();
  console.log(`${platform}: ${link.shortUrl}`);
}

Then use their webhooks to log conversions:

// This fires every time someone clicks your link
app.post('/webhook/dub', (req, res) => {
  const { event, data } = req.body;

  if (event === 'click') {
    db.clicks.insert({
      link: data.key,
      timestamp: new Date(),
      country: data.country,
      device: data.device
    });
  }

  res.sendStatus(200);
});

Run this once and you never manually create links again. You get a complete audit trail of every click.

Bitly doesn't offer webhooks at all. Short.io does, but only on paid tiers.

The Real Cost Calculation

Let's say you run 10 campaigns per year and use the tools for 5 years.

Bitly ($35/month): 10 campaigns × 5 years × $35/month × 12 = $21,000

Short.io ($25/month): 10 campaigns × 5 years × $25/month × 12 = $15,000

Dub.co (Free): $0

That's not an exaggeration. That's the actual pricing difference. Even if Dub.co charged $10/month, it would be a better deal than Bitly.

But Dub.co doesn't charge. Custom domains, full analytics, API, webhooks, branded QR codes—all free. The paid tier ($12/month) is for teams that need advanced permissions and priority support, which is genuinely useful if you have 50+ links.

Why This Matters for Conversion Tracking

Marketers who care about conversions obsess over attribution. Which email subject line drove sales? Which ad platform paid off? Which traffic source is worth more?

Link analytics are the first step. They show you which links got clicks. Then you build from there—adding conversion pixels, utm parameters, and downstream tracking.

Dub.co makes this easier than competitors because:

1. Custom domains feel professional (customers don't see "bitly.com")
2. Full API access means you automate everything (no manual link creation)
3. Webhooks let you build custom tracking workflows (log clicks to your own database)
4. Free tier doesn't compromise core features (no "upgrade to see your data" games)

The Verdict

If you're paying for Bitly or Short.io, switch. If you're not tracking your links at all, start now.

Try Dub.co free (yes, the affiliate link is real—I use it myself and genuinely recommend it).

Set up a custom domain, create a link, install their snippet, and watch real-time analytics populate. It takes 10 minutes. No credit card required.

Then use the API to build whatever you need. Link expiration? Rotation? A/B testing links? Conversion goals? All possible. All free.

That's link analytics that actually make sense.
