What Are Amazon Headline Search Ads?

Amazon Headline Search Ads are a type of ad that helps sellers promote their products and brand to customers. They use keywords to target shoppers and charge sellers only when someone clicks the ad. These ads appear at the top of search results on both computers and mobile devices.

How Amazon Headline Search Ads Differ From Other Ad Types

Understanding the differences between Amazon’s ad types helps you choose the right strategy for your goals. Each format serves a distinct purpose in your advertising funnel, from driving immediate sales to building long-term brand awareness:

Ad Type	Description	Best For	Key Considerations
Sponsored Brand Ads (Headline Search Ads)	Promote a brand and multiple products; large ad at the top of search results; includes logo and custom headline	Increasing brand awareness and showcasing multiple products	More setup effort; usually higher engagement and ROI
Sponsored Product Ads	Promote one product at a time; appear within search results; simple setup and lower cost per click	Driving quick product sales	Basic Amazon ad tool; easy and fast to launch
Display Ads	Appear on Amazon and external sites; reach audiences not actively shopping	Expanding reach beyond active shoppers	Slower sales cycle; more for awareness than immediate sales
Sponsored Display Ads	Target shoppers on/off Amazon, ideal for retargeting past visitors	Retargeting interested shoppers to boost conversions	Longer sales cycle; works best alongside search ads
Amazon DSP	Advanced audience targeting across devices; programmatic advertising	Large-scale, highly targeted campaigns	Requires a higher budget and expertise; not suited for small sellers

The Role Of Headline Search Ads In Your Business Strategy

Headline Search Ads offer three distinct formats, each serving different marketing objectives. Choosing the right format helps you align your advertising with your business goals and maximize campaign effectiveness.

Product Collection Ads

Product Collection Ads let you feature up to three products with images, titles, star ratings, and review counts. This format is particularly useful for sellers with related products because it allows customers to compare options directly within the ad, which can lead to higher engagement and multiple purchases.

By presenting several products together, these ads make it easier for shoppers to make informed decisions quickly. Consequently, sellers can see a direct impact on sales, especially in categories where buyers like to evaluate multiple options before committing.

Store Spotlight Ads

Store Spotlight Ads display your brand logo and a custom headline, guiding customers to your Amazon store rather than individual product pages. This approach helps sellers introduce new products and strengthen overall brand recognition, encouraging shoppers to explore the full range of offerings.

Because the ad focuses on the brand rather than single items, it creates a cohesive experience for the customer. In turn, this can increase long-term loyalty, as buyers become more familiar with your brand and are more likely to return for future purchases.

Video Ads

Video Ads allow 15–30 second videos to play directly in search results on both mobile and desktop devices. These ads capture attention more effectively than static images, giving sellers a powerful way to demonstrate product features or tell a short brand story.

The visual and interactive nature of videos keeps shoppers engaged longer, which often translates to higher click-through rates and conversions. As a result, businesses can use this format to not only inform but also emotionally connect with potential customers, boosting both awareness and sales.

Step-By-Step Guide To Setting Up A Headline Ad Campaign

Follow these six steps to launch and optimize your Sponsored Brands campaign for maximum performance and profitability.

Step 1: Conduct Thorough Research

Start by analyzing competitor ads appearing for your target keywords to understand what’s working in your niche. Next, identify your top-performing products with strong conversion rates and healthy profit margins. 

Use Amazon’s Search Term Report or tools like Helium 10 to compile 25-50 high-volume keywords, then calculate your target ACoS (15-30% for established products, 40-50% for new launches).

Step 2: Set Up Your Campaign And Ads

Log in to Seller Central and follow these steps to create your campaign:

• Navigate to Campaign Manager, click “Create Campaign,” and select “Sponsored Brands”.
• Name your campaign clearly (example: “SB-KitchenTools-Sales-Jan2025”), set a daily budget $20-50 minimum, and choose “Dynamic bids – down only”.

Next, you should configure your ad creative by selecting your campaign goal (Drive Page Visits, Grow Brand Impression Share, or Reserve Share of Voice), choosing your ad format, uploading your logo, writing a headline under 50 characters, and selecting 3 products with your landing page destination.

Step 3: Choose Relevant Keywords

You can add 25–50 keywords by using exact match for control, phrase match for moderate reach, and broad match for discovery. You also need to include your branded terms, category keywords, and long-tail variations so that you can cover different search intents. 

Next, you are advised to set your bids following Amazon’s suggested range (typically $0.50–$3.00), bidding slightly above the minimum to secure competitive placement. Additionally, you may allocate 20–30% higher bids for top-of-search positions, as conversions are typically strongest in these spots.

Step 4: Monitor Campaign Performance

Check daily during the first week to ensure your budget paces correctly and ads display properly. After one week, switch to weekly monitoring by downloading your Search Term Report, Placement Report, and Targeting Report.

Focus on key metrics like impressions show visibility; CTR (target 0.3-0.5%) indicates creative effectiveness, conversion rate (target 10-15%) reflects listing quality, and ACoS measures profitability against your target.

Step 5: Adjust Based On ACoS And ROI

Review your campaign performance and make adjustments based on your ACoS results:

• If ACoS is above target: Lower bids on high-ACoS keywords by 15-25%, add negative keywords for irrelevant searches, and pause keywords with 3x average CPC spend and zero conversions.
• If ACoS is below target: Increase bids on profitable keywords by 15-30%, raise daily budget to capture more volume, and add more related keywords for top-of-search placement.

Step 6: Test And Refine Headlines

Start by duplicating your campaign with different headlines while keeping products, keywords, and bids identical. Then, you should test benefit-focused, problem-solution, or value proposition angles for 2 weeks. Finally, you compare CTR and conversion rates to identify the winner and implement the top-performing headline across all campaigns.

Tips To Boost Headline Search Ad Performance

Once your campaign is live, apply these proven optimization techniques to improve CTR, lower ACoS, and increase conversions.

Craft An Engaging Headline

Your headline is the first thing shoppers see, directly impacting your click-through rate. Strong headlines can increase CTR by 30-50% compared to generic copy, which means more traffic at the same ad spend.

For example, you should replace “High-Quality Kitchen Tool” with “Cut Prep Time In Half With Professional Chef Knives”. Next, you can test 3-4 variations using different angles: benefit-driven (Save 2 Hours Daily), problem-solving (Stop Wasting Money On Broken Tools), or value-focused (Premium Quality At Half The Price). 

Review Impressions And Clicks

Check your Campaign Manager weekly to review impression and click data. If your impressions are low (under 1,000 per week), you need to increase your bids by 20-30% or add more keywords to expand reach. If your impressions are high but clicks are low (CTR under 0.3%), you should refresh your headline to be more benefit-focused or update your product images to stand out better. 

Additionally, you can test different ad formats like switching from Product Collection to Video ads, which typically generate 2x higher engagement. After making these changes, track the results for at least one week before making further adjustments.

Evaluate Key Performance Metrics

You can optimize more effectively by tracking the key indicators behind your ad outcomes.

ACoS (Advertising Cost of Sales)

ACoS shows how much you spend on ads for every dollar of sales. For example, 25% ACoS means you spend $0.25 to make $1.00 in sales. Most sellers target ACoS under 30%, with the average ranging from 29-30% and new sellers typically achieve around 29%.

CTR (Click-Through Rate)

CTR measures how many people click your ad after seeing it. If 100 people see your ad and 1 clicks, that’s 1% CTR. Average CTR is around 0.4%, with good performance ranging from 0.5-1.0% and excellent performance above 1%.

Conversion Rate

Conversion rate shows how many clicks turn into purchases. If 10 people click and 1 buys, that’s 10% conversion rate. Sponsored Brands average around 6.9%, while Amazon’s overall conversion rates range from 9-10%, so you should target above 7% for solid performance.

Impression Share

Impression share indicates how often your ad appears compared to competitors. If customers search 100 times and your ad shows 50 times, you have a 50% impression share. Excellent impression share is above 70%, good performance ranges from 50-70%, and anything below 50% needs improvement.
