How do I use the Terapeak Research tool? inkFrog Support - June 02, 2017 10:08 If you're using an inkFrog plan that includes the Terapeak research tool you can find the option in SLister (inkFrog's listing page). In SLister, enter a few keywords about the product that you're selling and click the research button. You'll then be required to select an eBay category. The research is based upon the keywords that you enter as well as the category that is selected. Once the research completes, you will be provided with some suggestions which include title keywords, best duration, listing type, day, and time to begin & end the listing. You will also be shown the last 30 days of eBay closed listing pricing results as well as currently live pricing results.
