The Randomize button is a feature that allows you to shuffle the images in your content bucket.
Step 1: Go to your Content Dashboard on the left sidebar.
Step 2: Select Your Buckets.
Step 3: Select the Bucket you wish to randomize by clicking on the drop-down button to the left that says Action and choose Edit.
Step 4: Click on the randomize Bucket.
Step 6: A pop up will show asking if you are sure you want to randomize. Click Ok.
The example below is what a bucket may look like before randomization. You will notice several posts in a series that all look very similar. If we were to schedule the posts as is, they would all show up in a row.
Below is what the same Content Bucket looks like after we have Randomized it. All of the posts have been shuffled.
