A weight attribute determines the probability of the offer to be displayed when there is more than one offer to show to the visitor.

If your site has several offers that target the same visitor segments, a visitor can see only one of them at a time. In such situations LiveEngage uses a probability algorithm to decide which offer to display.

This algorithm is based on the values of the weight attribute of your campaigns and offers. First, the algorithm determines which campaign to display (if you have more than one campaign that the visitor can see), and then it determines which offer (within that campaign) to display.

The higher you set the value of the weight attribute, the greater the probability that the campaign / offer will be displayed to the visitor
