Negative match keywords, often referred to as negative keywords, are a crucial tool in PPC advertising that allows advertisers to exclude specific search terms from triggering their ads. By using negative keywords, advertisers can refine their targeting and prevent their ads from appearing in irrelevant searches, ensuring ad spend is directed toward more relevant and potentially profitable queries.

How Negative Match Works

Negative match keywords work by excluding certain terms or phrases from campaigns, so ads don’t appear when those specific words are searched. For example, if you sell luxury watches and want to avoid clicks from users searching for “cheap watches,” you would add “cheap” as a negative keyword.

The importance of using negative keywords cannot be overstated. They help advertisers avoid wasting money on clicks from users who are unlikely to convert, thereby improving ROI. Negative keywords can be used in various match types, including broad match, phrase match, and exact match, each offering different levels of exclusion precision.

Broad match negative keywords block your ads from appearing in searches that include your negative keyword in any order, as well as searches that include synonyms or related terms. Phrase match negative keywords prevent your ads from showing when the exact phrase, including close variants, is part of the search query. The flexibility in choosing different match types allows for more control over when your ads are displayed. 

Examples of Negative Match

To illustrate how negative match keywords work, let’s got back to the previous situation when you’re a luxury watch seller. Consider the following examples:

• Broad Match Negative Keyword Example: Adding “cheap” as a broad match negative keyword will prevent your ads from appearing in searches like “cheap watches,” “affordable watches,” or “inexpensive watches.”
• Phrase Match Negative Keywords Example: If you use “cheap watches” as a phrase match negative keyword, your ads will be excluded from searches like “cheap watches online” or “buy cheap watches,” but could still appear in searches like “watches for men.”

When to Use Negative Match

Using negative match keywords strategically can prevent wasted ad spend and improve the relevance of your ad impressions. Best practices for using negative keywords include:

• Creating Negative Keyword Lists: Grouping common irrelevant terms into lists can save time and ensure consistent exclusion across multiple campaigns.
• Refining Campaigns with Broad and Phrase Match Negative Keywords: Use broad match negative keywords to cover a wide range of irrelevant terms and phrase match negative keywords to block specific phrases that are not relevant to your business.
• Regularly Reviewing and Updating Negative Keywords: As your campaign evolves, so should your negative keyword lists. Regular analysis helps you adapt to changing search behaviors and trends.

However, a common pitfall is overusing negative keywords, which can overly restrict ad visibility. It’s important to strike a balance, ensuring ads are not excluded from too many searches while still blocking irrelevant traffic.

How to Find Negative Keywords

Finding the right negative keywords requires continuous monitoring of search term reports and understanding the search intent behind keywords. Tools like Google Ads Keyword Planner can help identify potential negative keywords by showing search terms that trigger your ads but are not relevant to your offerings. By analyzing this data, you can add these terms to your negative keyword lists and optimize your campaigns for better performance.
