When listing to Trading Post, you must include a Short Description (called Subtitle in MarketplaceAdvisor Premium). This field can contain up to 55 characters.
This field, along with the Title, are the only fields that are indexed for searches on Trading Post. Your main description does not get searched.
Therefore, you may want to use this field a little differently than you have for other marketplaces. Rather than just having a subtitle to make you stand out from your competitors, you'll want to use this field for keywords that are not already in your title.
The best way to do this is simply with a list (no commas) of relevant keywords. In MarketplaceAdvisor Premium, you will want to use a custom Attribute to store this list of keywords.

The best way to get these new Attributes into your account is via the Bulk Update spreadsheet. Here is a link with more information on that:
