What the result means
Negative keywords in Google Ads prevent your ads from showing for unwanted search queries. A negative keyword conflict occurs when a negative keyword inadvertently blocks one of your targeted positive keywords, eliminating impressions, clicks, and conversions for valuable commercial traffic. This tool evaluates your positive keywords against negative keywords using Google's official negative matching specifications. Broad match negatives block queries containing all negative terms in any order. Phrase match negatives block queries containing the exact phrase in unbroken order. Exact match negatives block only identical queries with no extra words. Because negative keywords never match close variants or misspellings, this simulator pinpoints the precise negative term causing each conflict on your device.
The table below summarizes Google's official negative keyword matching rules across all three match types:
| Negative Match Type | Syntax | Matching Rule in Google Ads | Example Query: "blue running shoes" | Example Query: "shoes running" |
|---|---|---|---|---|
| Broad match | running shoes | Blocks if all terms appear in the query in any order. | ❌ Blocked (both terms present) | ❌ Blocked (order does not matter) |
| Phrase match | "running shoes" | Blocks if terms appear in the exact order without other words between them. | ❌ Blocked (exact phrase present) | ✔ Ad shows (wrong word order) |
| Exact match | [running shoes] | Blocks only if the query contains the exact terms with no extra words. | ✔ Ad shows (extra word "blue") | ✔ Ad shows (extra word and wrong order) |
Critical Google Ads Rule: Negative keywords do not expand to close variants, synonyms, or singular/plural forms. For example, a negative keyword for running shoes will never block searches for running shoe or runing shoes.

Questions
What is a Google Ads negative keyword conflict?
A negative keyword conflict occurs when a negative keyword at the account, campaign, or ad group level prevents ads from serving for one of your targeted positive keywords. For example, adding 'free' as a broad negative keyword to filter tire-kickers will inadvertently block high-intent queries like 'free consultation personal injury lawyer' or 'enterprise software free trial'.
Do Google Ads negative keywords match close variants or misspellings?
No. Unlike positive keywords—which automatically expand to misspellings, singular and plural forms, stems, and synonyms—Google Ads negative keywords only match the exact words entered. If you add the broad negative 'running shoes', your ad can still serve on 'running shoe' or 'runing shoes' unless you explicitly add those variants as separate negatives.
Why are broad match negative keywords considered high risk in Google Ads?
Broad match negative keywords block any search query that contains all of your negative words anywhere in the query, regardless of word order or intervening words. A broad negative like 'shoes' in a footwear campaign will block 'best trail running shoes for marathon runners', causing silent drops in impression volume and missed revenue.
How do I fix a negative keyword conflict without opening my budget to unwanted clicks?
Instead of deleting the negative keyword entirely, narrow its match type. If broad negative 'free' is blocking 'personal injury lawyer free consultation', replace it with exact match negative '[free lawyer]' or phrase match negative '"free legal advice"'. This keeps unwanted informational searches blocked while allowing your profitable consultation queries to serve.
How does this conflict checker simulate Google Ads negative matching?
The tool executes Google's exact negative matching algorithm directly in your browser. It tokenizes words, respects punctuation boundaries and ampersands, treats accented characters (such as café vs cafe) distinctly per Google's specifications, and audits hundreds of keyword pairs simultaneously without uploading your proprietary PPC data to external servers.
