The Limitations of Search Term Data in Ad Optimization

As Amazon Advertising grows increasingly competitive, brands must implement precise keyword targeting to maximize visibility and optimize ad spend. While Amazon’s Search Term Report provides insights into consumer intent and keyword performance, it has several limitations that hinder advertising strategies.

For brands managing multi-variant ASINs—such as apparel, electronics, and CPG products—advertising campaigns often group multiple ASINs into a single ad group, creating challenges such as:

  • Lack of ASIN-level keyword performance data
  • Difficulty in identifying high-converting search terms for individual products
  • Inefficiency in manually scaling keyword additions and exclusions
  • Inability to link top-performing keywords to the correct ASINs for optimized targeting

These limitations result in inefficient budget allocation and reduced campaign effectiveness, preventing brands from maximizing their return on ad spend (ROAS)

AI-Powered Keyword Optimization with AMC Data

To address these challenges, Xnurta’s AI-driven AMC keyword optimization introduces a data-driven approach to automating keyword expansion and refining targeting at the ASIN level.

By leveraging Amazon Marketing Cloud (AMC) data, brands using Xnurta can:

  • Automatically identify high-converting keywords at the ASIN level
  • Expand keyword targeting with AI-driven precision
  • Reduce manual campaign adjustments through real-time automation
  • Enhance ad efficiency by linking the right keywords to the right ASINs

Breaking the Barriers of Search Term Data

Since AMC data became available for Sponsored Ads, advertisers have primarily focused on audience segmentation and bid adjustments. However, AMC also unlocks valuable keyword insights, revealing deep correlations between search terms, ASINs, and ad placements—previously inaccessible through traditional reporting.

Enhancing Keyword Precision

Traditional keyword targeting methods failed to distinguish which ASIN within a multi-ASIN campaign was responsible for a keyword’s success. This lack of visibility often resulted in inconsistent performance and ineffective budget allocation when scaling ads across product variations.

With AMC data, brands can now precisely match high-performing search terms to the ASINs generating conversions, ensuring ad spend is directed toward the most impactful keywords while reducing wasted spend on irrelevant ones.

Improving Operational Efficiency

In the past, users had to manually create multiple single-ASIN ad groups and cross-compare search term reports to evaluate keyword effectiveness—a time-consuming and inefficient process.

Xnurta’s AI-powered automation eliminates this complexity by:

  • Dynamically analyzing ASIN-specific search term performance
  • Automatically optimizing campaign structures in real-time
  • Ensuring each ASIN is mapped to its most relevant keywords

AI-Powered Real-Time Adjustments

As the first eCommerce SaaS platform to integrate AMC data for AI-driven keyword optimization, Xnurta has developed an advanced machine-learning model that:

  • Processes real-time AMC data, including user behavior, ad placement performance, and ASIN conversion paths
  • Analyzes historical keyword conversion rates, ACoS, and profitability to refine campaign strategy
  • Automatically maps keywords to the most relevant ASINs, improving conversion rates and ad efficiency
  • Uses predictive modeling to direct advertising budgets toward the highest-performing keywords

Efficient Execution and Smart Adjustments

To eliminate ineffective keyword harvesting and prevent unnecessary competition, Xnurta’s system leverages a pruning algorithm that automatically refines keyword selection by:

  • Filtering out negated keywords that have already been excluded at the ad group level
  • Removing duplicate or already-added keywords to avoid redundant bidding and wasted budget
  • Recognizing variations in singular/plural forms, prepositions to optimize keyword targeting

For specific ad groups, such as brand defense and competitor targeting, the system maintains a structured and clean ad group hierarchy, ensuring that irrelevant keywords do not interfere with optimization efforts.

As illustrated in the diagram:

  • At the managed group level, the algorithm detects whether AI-driven keyword harvesting is enabled in Xnurta’s backend.
  • At the campaign level, it identifies budget constraints or inactive settings that may impact keyword harvesting.

By dynamically pruning unnecessary elements, Xnurta’s AI-driven system ensures that keyword expansion remains precise, structured, and efficient, allowing brands to maximize their ad performance with minimal manual intervention.

How a Top-Selling Yoga Brand on Amazon Optimized Ads with AI-Powered Keyword Targeting

A leading yoga apparel brand on Amazon, managing multiple ASINs in their ad campaigns, faced challenges in optimizing keyword targeting. Their previous strategy relied on broad keywords like "women leggings", which led to mixed search term data and inconsistent ad performance.

By implementing Xnurta’s AI-powered AMC keyword optimization, the system automatically identified high-converting long-tail keywords, such as “red leggings for women with pockets”, and precisely mapped them to the best-performing ASINs.

Results in Two Weeks:

  • 38.51% increase in impressions
  • 5.74% increase in clicks
  • 34.71% decrease in ACoS

A representative from the brand shared their experience:

“When structuring ad campaigns for multi-variant products, we often had to group multiple ASINs of different sizes into the same campaign to simplify management and consolidate the budget. However, this approach often resulted in mixed search term data, making it difficult to accurately evaluate individual ASIN performance, leading to unstable optimization results.

Xnurta’s new feature solved this issue perfectly. By combining AMC data with AI algorithms, it establishes a direct correlation between ASINs and customer search terms. The AI optimizes keywords intelligently based on the performance of each ASIN.

During the beta testing phase, we saw significant improvements—conversion rates increased, and ACoS dropped noticeably.

This exceeded our expectations and gave us a new perspective on AI.
