One of Tracker.ly's features helps you get more clicks by increasing desire through scarcity. When something has limited availability, its value goes up.
It works by limiting how many people can click on a tracking link to get to a destination, or how long the tracking link will send people to that destination. During that time, the scarcity is active and sending people to the initial destination. Once the limit is reached, the scarcity offer is complete or expired, and people who click on the tracking link to are sent to a second destination called an expired destination. This second destination might be something like a "too late" page or a secondary offer of some sort, like a down-sell. Or, perhaps the fist page is a coming soon page, and if people click the link after a launch, they go to the sales page.
It's up to you to communicate when publishing the link that there is a limit and that people need to act fast.
Scarcity is applied to the redirect links pointed to a destination, so you can get to it either by managing a redirect link you want to apply scarcity to, or by going to the section in the wizard to manage scarcity offers. If you have lots of redirect links pointed to a destination and want to add scarcity to some or all of them, just pick one of them at random to start with.
Here, I have a redirect link setup to demonstrate it. It points to google.com, which will be my initial destination. The scarcity button shows us that no scarcity is setup. Clicking it will let us add scarcity to this redirect:
The first step is selecting the type of scarcity to add. For this demonstration, we'll limit the number of people who will be able to get to the initial destination of google. Once that number is reached, we'll send everyone else to bing. So, we'll pick the first option and click "Next":
On the next screen, you give this scarcity offer a reference name and set the limits. If this were a time-limited offer, you would set the date and time the offer would expire. In this case, you limit it to the number of unique people who can go through the link. I'll limit it to one person, just for a demonstration:
Remember when I said, that if you had lots of redirect links pointed to this destination, and if you wanted them to be part of the scarcity offer to just pick one at random and set it up on that one? That's because on the next step, you have the option to add the scarcity to any other redirect links that are also pointed to the initial destination. In this case, I won't, but there are three other redirect links pointed to my initial destination, google.com, and I could include some or all of them by choosing the other option. If I did, the next screen would let me pick which ones to include.
And, because I might add more redirect links that point to my initial destination (google.com in this case) at some later date, I can tell Tracker.ly if I want all future redirect links pointed to it to also have the scarcity offer applied to them. That way, I can add more traffic sources with unique redirect links, and they'll automatically be included in the scarcity offer:
The final step is to select the destination to send people when the scarcity is expired, that is, when the date I set is passed, or in this case, when the total number of unique visitors has been reached. This might be a "too late" page for example. In this case, I'm just going to switch to bing.com. If my destination doesn't exist yet, I can create it by clicking on the "New Destination" button, and I'll return here after:
The whole process only takes a few seconds.
NOTE: With a quantity-limited scarcity offer, it's the unique people, so with it set to one person, you can click that link over and over again, and always go to the initial destination, even though the first click would have (in this case) been recorded as the first person, and be the only person allowed. Since you're allowed, you keep getting be allowed. If you open it up in another browser, or use a different computer, you'll be considered a new person, and see the destination set as the expired offer if the limit has been reached, which it was in my case with 1 person.
