Campaign Bidding and Budget
Setting your bid and budgetYou decide how much you want to spend promoting your book. As with other methods of advertising, we can't guarantee that placing ads will turn into sales for your books. To help you budget your campaigns, we provide suggested keyword budgets based on search demand. This is only available for Sponsored Products broad match keyword auto-targeting.
Bid+Bid+ is a Sponsored Products feature that increases the opportunity for your ads to show in the top of search results. When Bid+ is turned on, Amazon increases the default bid for your ads by up to 50% when they compete for the top of search results location (provided they are eligible to show there).
For example, if your default bid is $0.50, Bid+ can raise your bid as high as $0.75 to compete for impressions at the top of search results. You can turn on Bid+ for any manually targeted campaign. Bid+ is only available for the top of search results location, and can only be turned on for manually targeted campaigns. The daily budget will remain as you set it, regardless of Bid+.
You can turn Bid+ on and off in the campaign manager. To get started, find your campaign and click the Campaign Settings tab. Here you can enable Bid+ once your campaign is active.
Cost-per-click (CPC) bidAmazon Advertising uses a cost-per-click (CPC), auction-based pricing model. The CPC bid is the amount you are willing to pay when a user clicks your ad. The price you set is paid in an auction for ad space; other advertiser's books might be good matches for the same placements as your books. The winning bidder pays only if their ad is clicked.
We recommend you set the maximum CPC you are willing to pay. The more competitive your bid is, the more likely your ad will be displayed. The minimum CPC is $0.02 and you will never be charged more per click than what you bid. It's important to remember that you're competing with other advertisers for delivery. This means that if you set a cost-per-click bid that's lower than other live ads, your ad may not be shown.
Note: If the Bid+ setting is on and your ad is clicked in the top-of-page placement, it's expected that your average CPC will increase.
