To match your competitor's price, you can set your rule using one of the following two settings.
- Competitor's Price - 0.00
- Buy Box Price - 0.00
However, there is no guaranteed way to ensure you match your competitor's price when you're in the Buy Box.
Matching your competitor's price is not advisable because even if you match the price, you may not overtake the position, and your ranking could still be influenced by other factors, such as seller metrics.
