## Frequently Asked Questions (Direct Citation Q&A)
### Q: Why is my actual eBay Promoted Listings fee higher than the ad percentage I set?
A: Because eBay multiplies both your 13.25% Final Value Fee and your Promoted Listings Standard ad percentage against the buyer's total checkout amount—which includes item price, buyer-paid shipping, and state sales tax. On an $85 item with $8 shipping and 8% sales tax ($100.44 total), a 10% ad rate costs $10.04, which is 11.8% of your $85 item price.

### Q: What is eBay's 30-day Halo attribution rule on Promoted Listings Standard?
A: If a buyer clicks on any of your Promoted Listings Standard items and purchases a different promoted item from your store within 30 days, eBay attributes a 'Halo sale' and charges the promoted ad rate in effect on the purchased item—even if the buyer found the second item organically.

### Q: When should an eBay seller use Promoted Listings Advanced (CPC) instead of Standard (CPA)?
A: Standard CPA charges a percentage of the total sale, so ad costs balloon on high-ticket items ($100+). If a $160 SKU converts at 5.5% with a $0.40 exact-match CPC bid, your ad cost per order is ~$7.27 (4.5%), whereas eBay's 'Suggested 9.5% Standard Ad Rate' would cost $16.41 per order.

### Q: Why is accepting eBay's 'Dynamic Suggested Ad Rate' dangerous for resellers?
A: eBay's dynamic suggested ad rate routinely climbs to 10%–14% in competitive categories like apparel, auto parts, and electronics. Stacked with the 13.25% Final Value Fee + $0.40 per-order fee on tax-grossed totals, your total platform fee exceeds 27% of gross revenue.

### Q: How does offering 'Free Shipping' vs. 'Buyer-Paid Shipping' impact eBay ad fees?
A: Since eBay charges both Final Value Fees and Promoted Listings Standard percentages on the combined Item + Shipping + Tax total, splitting shipping out no longer shields it from fees. However, factoring your actual PirateShip/USPS Commercial label discount against the fee base is critical to avoid negative shipping margin.

### Q: Does eBayAdMargin Studio require connecting our eBay Seller Hub account?
A: Never. All Final Value Fee, sales-tax gross-up, and CPA vs. CPC calculations run 100% locally in your browser RAM with zero cloud uploads.
