If you're launching a new Sponsored Products campaign, you've probably seen the option to add a bid adjustment for "Top of Search" placement. The big question every Amazon seller asks is simple: should you start aggressive with a high Top of the Search adjustment in Amazon PPC Sponsored Product ads, or play it safe with 0%?
The short answer: it depends on your product stage, budget, and goals. The longer answer involves understanding how placement bidding actually works, what data you need before you scale up, and how to avoid wasting money on clicks that don't convert.
In this guide, you'll learn when a high Top of Search adjustment makes sense, when it's a budget killer, and how to set the right percentage based on your campaign type. Let's break it down.
Before you source your first product, make sure you have the fundamentals locked in. This free checklist is used by hundreds of Bubba Academy students to launch faster and avoid costly rookie mistakes.
Amazon Sponsored Products ads can appear in three placements: Top of Search (first row of results), Rest of Search, and Product Pages. The Top of Search adjustment tells Amazon how much extra you're willing to pay (as a percentage above your base bid) to win that premium spot.
For example, if your base bid is $1.00 and you set a 100% Top of Search adjustment, Amazon may bid up to $2.00 to place your ad at the top.
Why this matters: - Top of Search converts 2–3x better than other placements for most categories - It captures buyers with high purchase intent - It builds organic ranking faster because of click-through and sales velocity - It also costs significantly more per click
The adjustment ranges from 0% to 900%. Higher doesn't always mean better. Your goal is finding the sweet spot where ACoS stays profitable while you capture enough top-of-page impressions to drive conversions and rank.
Beginners often hear "Top of Search converts best" and immediately set 100% or higher on day one. This usually backfires. Here's why:
The smarter approach: start with 0% Top of Search adjustment for the first 7–14 days. Let the campaign collect data on which search terms convert. Once you know your winning keywords, then increase placement adjustments strategically — not blindly.
There are specific scenarios where pushing hard for Top of Search from the start is the right call. Consider a higher adjustment (50–100%+) when:
If most of these apply, start with a 50% adjustment, monitor for 5–7 days, and scale up to 100% if ACoS stays within your target. If your product is brand new with no reviews and a generic listing, skip the high adjustment entirely.
Product research is where most beginners make expensive mistakes. Bubba Academy gives you a proven, data-driven framework so you can identify profitable, low-competition products with real confidence.
Use this practical framework instead of guessing:
Step 1: Check your placement report. Go to Campaign Manager → Campaign → Placements tab. Review the last 30 days. Look at impressions, CTR, conversion rate, and ACoS for each placement.
Step 2: Compare conversion rates. - If Top of Search conversion rate is 2x or higher than other placements, increase the adjustment. - If it's similar to Rest of Search, keep adjustment low or 0%.
Step 3: Calculate the maximum adjustment. Use this formula: - Max Top of Search bid = Target ACoS × Average Order Value × Top of Search conversion rate - Then: (Max Top of Search bid ÷ Base bid − 1) × 100 = Max adjustment %
Step 4: Start at 25–50% and scale. Increase by 25% every 5–7 days as long as ACoS stays within target. Decrease if ACoS exceeds your break-even point.
Step 5: Separate by campaign type. - Exact match campaigns with proven keywords: higher adjustment (50–150%) - Broad and auto campaigns: lower adjustment (0–25%) - Branded campaigns: highest adjustment (100–300%)
Even experienced sellers fall into traps with Top of Search adjustments. Avoid these:
The biggest mistake is treating Top of Search adjustment as a "set and forget" setting. It needs review every 7–14 days, especially in the first 90 days of a campaign.
Here's a practical playbook based on where your product is in its lifecycle:
Launch phase (0–30 days): - Auto campaigns: 0% adjustment - Broad/Phrase research campaigns: 0% adjustment - Exact match on hand-picked keywords: 25–50% - Brand defense: 100%+
Growth phase (30–90 days): - Auto campaigns: 0–15% - Broad campaigns: 15–25% (only on converting search terms) - Exact match (proven): 50–100% - Brand defense: 100–200%
Scale phase (90+ days): - Auto campaigns: 25% if profitable - Broad: 25–50% - Exact match (top performers): 100–200% - Brand defense: 200%+
Mature phase (consistent rank and sales): - Optimize for profit, not visibility - Reduce adjustments where ACoS exceeds target - Keep high adjustments only on hero keywords driving organic rank
This staged approach keeps your spend efficient while still aggressive enough to grow.
Starting with a high Top of Search adjustment in Amazon PPC Sponsored Product campaigns is rarely the right move for new products or unoptimized listings. The smart approach is to begin at 0%, gather conversion data for 7–14 days, and only then increase the adjustment based on actual placement performance.
Key takeaways: - Don't set high adjustments without conversion data - Use placement reports to guide your percentage - Match the adjustment level to your campaign stage and match type - Always own Top of Search for branded keywords - Review and adjust every 1–2 weeks
Your next step: Open your Campaign Manager today, go to the Placements tab on your top-spending campaign, and review the last 30 days of data. If Top of Search conversion rate beats other placements by 2x, raise the adjustment by 25%. If not, drop it to 0% and reinvest that budget into base bids on proven keywords. Small, data-driven adjustments beat aggressive guesses every time.
You've learned the concepts. Now build the business. Bubba Academy gives you a complete step-by-step roadmap — from finding your first product to your first profitable sale on Amazon.
No, it's not recommended to start with a high Top of the Search adjustment for new campaigns. Begin with 0% placement adjustment to gather clean data on which keywords actually convert. Once you have at least 2-4 weeks of performance data, you can apply adjustments based on which placements deliver the best ACoS.
Top of the Search adjustment is a bid modifier that increases your bid specifically for the top row of search results on Amazon. You can set it from 0% to 900%, and Amazon will multiply your base bid by that percentage when competing for top placement. This placement typically has the highest visibility and conversion rates but also the highest cost-per-click.
Increase it once you've identified profitable keywords with strong conversion rates and a healthy ACoS at the top placement. Check your placement report in Campaign Manager to see if Top of Search is converting better than other placements. Start small with 25-50% increases and scale up gradually based on results.
Anything above 100% without data backing it up is risky and can quickly drain your budget. Even with profitable keywords, jumping straight to 300-900% adjustments often leads to inflated CPCs without proportional returns. Always test incrementally and monitor your ACoS closely after each adjustment.
In most cases, yes, Top of Search delivers higher click-through and conversion rates compared to Rest of Search or Product Pages. However, it also has the highest CPC, so higher conversions don't always mean better profitability. Always compare ACoS across placements before deciding to boost your bid adjustment.
