Dynamic Bids \u2013 Down Only<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Amazon lowers your bid when it thinks the click is less likely to convert. This helps save money on unprofitable clicks.<\/span><\/p>\n<h3><b>2. Dynamic Bids \u2013 Up and Down<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Amazon can increase your bid (up to 100%) when a click is more likely to convert and decrease it when it\u2019s less likely. Great for high-conversion campaigns.<\/span><\/p>\n<h3><b>3. Fixed Bids<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Your bids stay exactly as set\u2014no algorithmic changes. Gives you full control but less flexibility.<\/span><\/p>\n<h2><b>FAQs: Amazon Bidding Algorithm<\/b><\/h2>\n<h3><b>1. What determines whether my ad wins an auction?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Winning isn\u2019t just about the highest bid. Amazon looks at:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Bid amount<\/span><span style=\"font-weight: 400;\">\n<p><\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Relevance of your ad and keywords<\/span><span style=\"font-weight: 400;\">\n<p><\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Performance metrics (CTR, CVR, etc.)<\/span><span style=\"font-weight: 400;\">\n<p><\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Product listing quality<\/span><\/li>\n<\/ul>\n<h3><b>2.

Can I lose an auction even if I bid the highest?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Yes. If your ad or listing is not relevant or optimized, Amazon may give the spot to a lower bidder with better relevance and expected performance.<\/span><\/p>\n<h3><b>4. How often does Amazon update bids in dynamic bidding?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Bids are adjusted in real time, based on contextual signals like:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">User search behavior<\/span><span style=\"font-weight: 400;\">\n<p><\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Device type<\/span><span style=\"font-weight: 400;\">\n<p><\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Time of day<\/span><span style=\"font-weight: 400;\">\n<p><\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Placement (Top of Search, Product Page, etc.)<\/span><\/li>\n<\/ul>\n<h3><b>5.
