Most of us share links everywhere. Instagram bio. WhatsApp groups. Email. Ads. A poster with a QR code. Then a sale happens, and someone asks a simple question. Which link did it?
If you cannot answer that, you are guessing. And guessing is expensive.
I learned this the hard way while building Fewly. I am Moinul Haq, the founder, and I built it because I was tired of short links that only told me a click happened. A click is not a sale. A click is not even a sign that someone liked your product. It just means someone tapped.

Start with one question
Before you shorten anything, decide what you want to learn. Do you want to know which platform works best? Which ad creative works best? Which email subject line gets people to actually buy?
One link per answer. That is the whole trick.
If you use the same link on Instagram, WhatsApp, and email, your numbers will blend together. You will see 500 clicks and feel good. You will have no idea where those 500 people came from. Use a separate link for each place, even if they all go to the same page. It takes a few extra seconds, and it saves you weeks of guessing later.
Give every link a clear name
A back-half is the part after the slash. Use it well.
A link called /sale is fine. A link called /sale-instagram is better. A link called /sale-instagram-reel-nov is best, because six months later you will still know what it was.
Keep names short, readable, and honest. Do not use random letters if you can avoid it. Future you will thank present you.
Add UTM tags, but keep them simple
UTM tags are small labels you add to a link. They tell your analytics where a visit came from. Source, medium, and campaign are enough for most people.
For example, source can be instagram, medium can be bio, and campaign can be winter-sale. That is it. You do not need ten tags. You need three tags you will actually use the same way every time.
The common mistake is spelling the same thing five different ways. Instagram, insta, IG, and instagram-bio are four different campaigns in your reports, even though they are the same place. Pick one spelling and stick to it.
Clicks are only step one
Here is where most link tools stop, and where most confusion starts. You see clicks go up, but sales stay flat. What happened?
Maybe people clicked, but the page was slow. Maybe they clicked from the wrong country for your shipping. Maybe they clicked at midnight, when your shop was closed for live support. Clicks alone cannot tell you that.
You need to connect the click to what happened next. Did the person sign up? Did they add something to the cart? Did they pay? That is conversion tracking. In plain terms, it means your link tool and your checkout both agree on one thing: this sale came from this link.
When you have that, your decisions get easy. You stop spending on the link that gets clicks but no sales. You put more effort into the link that gets fewer clicks but more buyers. That is a very different list, and it is usually a surprise.

Watch device, country, and time
Three details change everything, and they are easy to miss.
First, device. iPhone users and Android users do not always behave the same way. If you sell an app, sending both groups to the same web page is a waste. Send iPhone users to the App Store and Android users to Google Play. It is a small change, and it removes a whole step for the buyer.
Second, country. If you only ship to one country, clicks from other countries are not bad, they are just not buyers. Knowing that stops you from thinking a campaign failed when it was actually shown to the wrong audience.
Third, time of day. Some links work best in the morning, some at night. If you post at the wrong hour, you are not testing the link, you are testing the clock. A busy-hour view helps here, because it shows when people actually tap, not when you think they will.
QR codes count too
A QR code on a menu, a package, or a poster is also a link. Treat it the same way.
Use a dynamic QR code, which points at a short link, if you want to change the destination later or count scans. A static QR code is fine for something simple like a WiFi password, because the data is inside the code itself and it never expires. For marketing, dynamic is better, because you can fix a mistake without reprinting everything.
And please test the print size. A tiny QR code on a busy package is not a link, it is a decoration. People need to scan it from a normal distance, with normal light, on a normal phone.

A simple weekly check
You do not need a daily dashboard ritual. Once a week, answer these five questions.
Which link got the most clicks? Which link got the most sales? Which link got clicks but no sales? Which platform sent the best buyers, not just the most visitors? What will you stop doing next week?
That last question matters most. Most of us only add new links. We rarely stop the ones that do not work. Stopping is free, and it frees up time for the links that actually bring money.
Keep it honest
One more thing. Do not chase a big click number for its own sake. A link with 10,000 clicks and zero sales is not a win. A link with 100 clicks and 10 sales is a business.
Short links are not magic. They are just a way to see clearly. When you can see which link brought the sale, you can make a better next move. That is the whole point.

I built Fewly to make that view simple, with real-time analytics, branded links, QR codes, and conversion tracking, starting free at fewly.tech. You can also read the docs at fewly.tech/docs to see how conversion tracking and routing work in plain steps. No matter which tool you use, though, the habit is the same: one link per place, clear names, simple tags, and sales, not just clicks, as the final score.
