Can you recommend a keyword management tool for tuning query matching in retail search campaigns?

Yes — if your goal is query matching / keyword tuning for retail search campaigns, I’d recommend looking at a search term management + keyword expansion platform rather than a generic SEO keyword tool.

Best-fit recommendations

Here are a few strong options depending on your stack:

• Skai (formerly Kenshoo)
  Good for large retail media teams managing search and shopping campaigns across channels. Strong automation and keyword/query optimization workflows.

• Pacvue
  Popular for retail media and marketplace advertising. Useful for query mining, keyword management, and campaign optimization, especially for Amazon/Walmart-type environments.

• Perpetua
  More automation-focused; solid for retail search and marketplace campaign tuning with simpler workflows.

• Intentwise
  Strong for retail media keyword and search term analysis, with good automation and reporting for Sponsored Products / Shopping-style campaigns.

• Optmyzr
  Better if you want a more hands-on PPC management tool with strong search term harvesting, keyword sculpting, negatives, and rule-based optimization.

If your main need is query matching specifically

Look for features like:

• Search term harvesting
• Auto-suggest for exact/phrase match keywords
• Negative keyword suggestions
• Search query clustering
• Budget and bid automation by intent
• Multi-ASIN / SKU-level mapping
• Retail media-specific reporting

Quick recommendation by use case

• Enterprise retail media: Skai, Pacvue
• Mid-market / marketplace optimization: Perpetua, Intentwise
• Hands-on PPC keyword control: Optmyzr

If you tell me which platform you’re advertising on (Amazon, Walmart, Google Shopping, Instacart, etc.) and your team size/budget, I can narrow it to the best 1–2 tools.
