Amazon PPC Guide: Sponsored Products Advertising
Amazon Ad Types Explained
Amazon offers three main advertising formats, each serving a different purpose. Sponsored Products are the workhorse of Amazon advertising. These keyword-targeted ads display your individual product listing in search results (marked "Sponsored") and on competitor product detail pages. Sponsored Products drives the most sales volume for most sellers and should be your first and primary campaign type. You can target by keywords (your product appears when shoppers search specific terms) or by product (your product appears on specific competitor listings).
Sponsored Brands (formerly Headline Search Ads) display a banner at the top of search results featuring your brand logo, a custom headline, and up to three products. These ads require Brand Registry enrollment and work well for brands with multiple products in the same category. Sponsored Brands drive brand awareness and send traffic to your Amazon storefront or a custom landing page showing your product lineup. They typically have a higher cost-per-click than Sponsored Products but build brand recognition that benefits all your listings.
Sponsored Display ads follow shoppers around Amazon and across the web, remarketing to people who viewed your product or similar products. Sponsored Display uses audience targeting rather than keyword targeting, reaching shoppers based on their browsing and purchasing behavior. These ads are effective for retargeting shoppers who viewed your listing but did not purchase, and for reaching customers who purchased complementary products. Sponsored Display is the newest format and requires Brand Registry.
Step-by-Step Campaign Setup
In Seller Central's Campaign Manager, create a new Sponsored Products campaign with automatic targeting. Amazon's algorithm will match your listing to search terms based on your listing content. Set a daily budget of $20 to $30, which gives the algorithm enough data to learn while limiting your daily exposure. Set a default bid of $0.75 to $1.25 for most categories (higher for competitive niches like supplements or electronics, lower for less competitive ones like home organization). Choose "Dynamic bids, down only" as your bidding strategy, which lets Amazon reduce your bid when a click is less likely to convert but never increase it beyond your set amount. Let this campaign run for 14 to 21 days before making major adjustments.
After 2 to 3 weeks, download the search term report from Campaign Manager. This report shows every search term that triggered your ad, the number of impressions, clicks, spend, and sales for each term. Sort by spend to find your biggest cost drivers, then evaluate each term. Search terms that generated sales at an acceptable ACoS (under 30% to 35% for most products) are winners. Terms that generated clicks but zero sales after meaningful spend ($10 to $20) are candidates for negative keywords. Terms that converted at very high ACoS (over 60%) may need lower bids rather than elimination, especially if they are highly relevant keywords.
Create a new Sponsored Products campaign with manual keyword targeting. Add your winning search terms from the automatic campaign as exact match keywords. Exact match means your ad only shows when a shopper types that precise search term, giving you the tightest control. Set bids based on the data from your automatic campaign: if a keyword converted at $0.85 CPC in the automatic campaign, set your manual exact match bid at $0.90 to $1.00 to capture the same placement. Create a second manual campaign using phrase match for your top 10 to 15 keywords. Phrase match shows your ad when the shopper's search contains your keyword phrase plus additional words before or after, providing broader reach while maintaining relevance.
In your automatic campaign and phrase match campaign, add negative keywords for search terms that are clearly irrelevant or that have proven unprofitable after sufficient testing. Add these as negative exact match to block only the specific unproductive term. For example, if you sell silicone kitchen utensils and your automatic campaign spent $15 on the search term "metal kitchen utensils" with zero sales, add "metal kitchen utensils" as a negative exact match keyword. This prevents future spend on that term while allowing your ads to continue showing for related but different searches.
Review campaign performance every week. For keywords with ACoS below your target (e.g., below 25%), increase the bid by 10% to 15% to capture more impressions and clicks at that profitable level. For keywords with ACoS above your target but still generating sales, decrease the bid by 10% to bring the cost into line. For keywords spending money without converting, lower the bid significantly or pause them. Shift daily budget from underperforming campaigns to your best performers. Over time, your manual exact match campaigns should become your biggest revenue drivers with the lowest ACoS, while your automatic campaign continues discovering new keyword opportunities at a higher but still acceptable cost.
Understanding ACoS and TACoS
ACoS (Advertising Cost of Sale) is your ad spend divided by your attributed ad revenue, expressed as a percentage. If you spent $100 on ads and generated $400 in ad-attributed sales, your ACoS is 25%. Your target ACoS depends on your product margins. If your pre-advertising profit margin is 40%, any ACoS under 40% means your ads are profitable. Most sellers target ACoS between 15% and 30%, though launch-phase ACoS of 40% to 80% is normal and expected while building ranking and reviews.
TACoS (Total Advertising Cost of Sale) measures your ad spend against your total revenue, including both ad-driven and organic sales. This metric matters more than ACoS in the long run because effective PPC advertising boosts your organic ranking, which generates free organic sales. If you spend $500 on ads generating $1,500 in ad-attributed sales (33% ACoS) but your total sales including organic are $3,000, your TACoS is 16.7%. A declining TACoS means your organic sales are growing relative to your ad spend, which is the ultimate goal of your advertising strategy.
Advanced PPC Strategies
Product targeting campaigns place your ads on specific competitor product pages. Create a manual Sponsored Products campaign with product targeting, and add the ASINs of competitors with weaker listings, higher prices, or fewer reviews than yours. When shoppers visit those competitor pages, they see your product as an alternative. This is particularly effective when you have a genuine advantage: a lower price, more reviews, better images, or a feature the competitor lacks.
Dayparting involves adjusting bids based on time of day. If your data shows higher conversion rates during evening hours and lower rates in the early morning, you can increase bids during peak conversion windows and decrease them during low-performing hours. Amazon does not offer built-in dayparting, but third-party tools like Helium 10's Adtomic or Perpetua can automate bid adjustments on a schedule.
Campaign budget optimization means allocating more daily budget to your most profitable campaigns during peak shopping periods. Before Prime Day, Black Friday, and the holiday season, increase budgets by 50% to 100% on your best-performing campaigns. Shopping volume surges during these events, and sellers who run out of daily budget miss sales opportunities. Conversely, reduce budgets during traditionally slow periods like January and February if your data confirms lower conversion rates during those months.
