How To Protect A Budget From Competitor-Branded Terms

This week’s question comes from Evan, who asked: “How do I prevent my PPC budget from getting eaten by branded competitor terms?”

It’s a good question, as few things frustrate advertisers more than watching transactional budgets get drained by competitor-branded searches. Marketing dollars intended for high-intent, conversion-ready audiences often get spent on clicks from users searching for competitors instead. These searches typically convert at lower rates and can produce deceptively low CPCs, creating false positives that distort performance data.

Protecting spend from competitor traffic requires a mix of negative keyword management, platform tools, and thoughtful campaign structure. Here’s how advertisers can take control and ensure their budgets stay focused on profitable intent.

Use Strategic Negatives

Negative keywords remain the most reliable way to prevent ads from serving on competitor-branded queries. Adding competitor names as phrase match negatives blocks variations of that brand name, while exact match negatives offer more precision when overlap risk is high.

However, advertisers must be careful. Some competitor names resemble valuable generic phrases. For example, if a competitor calls its business “Dog Trainer Near Me,” excluding that term could block qualified local leads. The goal is to remove competitor intent, not legitimate customer searches.

It’s also important to recognize that negative keyword limits are imposed by the ad platforms themselves. Google Ads and Microsoft Ads both restrict the number of negatives an account can include. Most advertisers can expect to cap out between 2,500 and 10,000 negatives per account, depending on structure and platform. Because of this limitation, advertisers should be selective about what they block.

The most efficient approach is to create a shared list of proven competitor negatives and apply it at the campaign or account level. This method saves space and keeps exclusions consistent across campaigns. Regularly review search term reports to identify new competitor variants and refine your list based on performance data.

Leverage Brand Inclusions And Exclusions In AI Campaigns

Advertisers running AI-driven campaign types, such as Performance Max, can use brand inclusion and exclusion controls to refine targeting. These tools allow advertisers to specify which brands their ads can or cannot appear alongside.

It’s important to understand that brand exclusions are not the same as negative keywords. A negative keyword blocks a specific word or phrase. A brand exclusion tells the system to avoid what it identifies as queries related to a particular brand. This AI-driven interpretation can reduce the need for lengthy negative lists, though close variants may still slip through.

These settings only apply to campaigns that use AI optimization, so advertisers must opt into automated formats to access them. If an account does not meet the required conversion thresholds for…
