See which Promoted Listings channel costs less per sale.
Included in the $9.00 Shelf Kit
eBay sellers and agencies choosing between sale-based and click-based Promoted Listings on their own numbers before a human configures a campaign.
Delivery: usually a structured result, workbook, or ZIP depending on the tool.
Friday performs scenario arithmetic only on the sale prices, Standard ad rates, Advanced cost-per-click bids, expected conversion rates, expected click counts, and unit contributions you provide. It reads no eBay account and looks up no live ad rate, suggested bid, auction result, or attribution record. The expected conversion rate is your estimate, not a forecast, and the cheaper channel is a comparison of your supplied scenario, not a campaign recommendation. Friday places no bid, creates or changes no campaign, changes no price, listing, or inventory, does not publish listings, and does not modify a seller account. Confirm current Promoted Listings terms before acting.
