You can use the Optimization Journal to test different parts of your description and see how those changes impact your listing's search rankings.
For example, let's say you changed your title to include emojis.
You'd click the "Track a Change" button and record the change you made to your description.
Then on the chart, you'll see annotations and indicators for when you made that change and the positive or negative impact that comes with those changes.
Optimizations to your listings take time to turn into positive results.
With the Optimization Journal, you can get a better sense of whether your rankings are heading towards the right direction.
You won't get to page 1, without going past the other pages first.
