WHY DO WE NEED FRESH OFFERS?
New offers provide huge potential in terms of conversion rate. All of these fresh offers have a clean database that can be filled. As you can imagine, the database of the offers that have been around for some time are more saturated hence the newer onese work better!
The new offers, in general, have a higher chance of converting because of this.
This is why you always want to push new offers right away from the launch.
