This is how to find wasted search terms in Microsoft Ads with AI: connect your Microsoft Ads account to PaidSync.ai, then ask Claude to show the search terms that spent money without a conversion, with the match type that delivered them. It only reads, and it feeds your negative keyword decisions.
The search query report is the evidence for negatives. It shows the real searches behind your keywords:
get_ms_search_query_performance returns what people searched, the keyword and ad that matched, the delivered match type and the conversions each term produced.list_ms_negative_keywords shows what is already blocked, so you do not repeat a negative.add_ms_negative_keywords adds the terms you decide to block, as a preview.get_ms_search_query_performance and list_ms_negative_keywords only read your account. add_ms_negative_keywords changes it. Claude calls these to find wasted search terms.
| Tool | What it does |
|---|---|
| get_ms_search_query_performance | Returns the real search terms |
| list_ms_negative_keywords | Shows existing negatives |
| add_ms_negative_keywords | Blocks the wasteful terms |
This report is the only one that shows Exact (close variant) and Phrase (close variant) as delivered match types, so its match type totals will not match other reports. Do not reconcile them against each other.
