Editorial Team Key Takeaways
- Use a tiered negative keyword strategy with broad, phrase, and exact match. It’s the foundation for stopping budget waste on irrelevant impressions.
- Get into your Search Terms Report in Google Ads every single week. This is where you’ll find new, real-world user queries to add as negatives.
- Use shared negative keyword lists across your campaigns. For big accounts, this is the only way to stay consistent and cut down on tedious manual updates.
- Don’t wait for bad clicks to happen. Add negatives for competitor names, products you don’t sell, and known garbage terms before your campaigns even go live.
- Set up automated rules or scripts in Google Ads to automatically flag or even pause ad groups that are burning cash on high-cost, zero-conversion search terms.
Getting your negative keywords under control is how you stop burning money and actually improve your return on ad spend. Just adding a couple of obvious “don’t show” terms is a start, but it’s not a real strategy. To do this right, you need a repeatable system that filters out the junk and gets your ads in front of actual buyers.
1. Establish a Tiered Negative Keyword Strategy
The most common mistake I see is people treating all negative keywords the same, just dumping them into one bucket. The reality is that different terms have different levels of irrelevance. You need a tiered approach that uses the right match type for the job.
Pro Tip: The “Why” Behind Tiering
Think of it like this: a broad match negative like `free` is a sledgehammer, it’ll block any search containing that word, which works if you literally never offer anything gratis. A phrase match negative like `”free download”` is more of a scalpel. It blocks searches for “free software download” but would still allow a query like “download speed test” to come through. Then you have an exact match negative `[free trial]`, which targets only that one specific, precise query. Your strategy has to account for this.
Common Mistake: Over-Negativing with Broad Match
Be careful with broad match negatives, because you can easily choke off good traffic by accident. If you sell high-end watches and add “cheap” as a broad negative, you might also block a totally valid search like “cheap shipping for luxury watches” if your ad talks about shipping. Always watch the impact after you add broads.
2. Systematically Analyze Search Terms Reports
The Search Terms Report is where you find your best negative keywords. You have to live in this report. This is an ongoing process, not something you do once at launch, and it absolutely should be part of your weekly campaign review.
Step-by-Step in Google Ads (as of 2026):
- Get into your Google Ads account.
- Pick the campaign or ad group you’re working on from the left-hand navigation.
- Click on “Keywords” in the main page menu, then go to “Search terms.”
- Set the date range for the last 7 to 30 days. I personally stick to a rolling 7-day window so I can react fast.
- Sort the whole report by “Cost” descending. This immediately shows you what’s eating your budget. You can also sort by “Conversions” to see what’s not working.
- Go down the list, term by term. For each one, ask: is this person actually looking for what I sell? Does their intent match my product?
- If a term is junk, check the box next to it and hit “Add as negative keyword.”
- Now choose your match type (exact, phrase, or broad). Think about the variations. If the term “DIY repair kit” is irrelevant for your pre-assembled product, adding it as a phrase match will block future searches like “DIY repair kit for bikes” and “best DIY repair kit” from wasting your money.
- Finally, decide where to add it, ad group, campaign, or a shared list. If a term is junk for your entire account, a shared list is the only efficient option.
Screenshot Description:
Imagine a screenshot of the Google Ads Search Terms Report. You’d see a “Search term” column with queries like “free online courses,” “cheap alternatives,” and “how to fix yourself.” Next to it, a “Cost” column shows you’re spending money on them, $15.23, $8.90, $2.10. There’s a checkmark next to “free online courses,” and the blue “Add as negative keyword” button at the top is highlighted.
3. Implement Shared Negative Keyword Lists
If you’re managing a large account, handling negatives one by one is a complete nightmare that just doesn’t scale. For maintaining any kind of consistency and efficiency, you need to be using shared negative keyword lists.
How to Create and Apply Shared Lists:
- In Google Ads, find the wrench icon for “Tools and settings” in the top right.
- Under the “Shared library” column, click “Negative keyword lists.”
- Hit the blue plus button to make a new list. Name it something clear and descriptive, like “Competitor Brand Terms” or “Irrelevant Service Types.”
- Start adding your negative keywords to this new list. You can mix and match broad, phrase, and exact types all in the same list.
- After you’ve built the list, you can apply it to as many campaigns as you want by going into the campaign settings, finding “Negative keywords,” and choosing “Use negative keyword list.”
Pro Tip: Segmenting Your Lists
I always build out several different shared lists, usually broken down by category:
- Competitor Names: Stops you from showing up when people are specifically looking for your competition.
- Irrelevant Products/Services: A list of terms for stuff you just don’t sell.
- Informational Queries: Words like “what is,” “how to,” and “examples” if you’re only trying to drive sales and not educate the entire internet.
- Job Seekers: A list with “jobs,” “careers,” “hiring” to filter out people looking for employment, not your product.
Breaking them up like this just makes the lists cleaner and easier to apply to the right campaigns.
4. Proactive Negative Keyword Research
Don’t wait to start bleeding money on bad clicks. You can save a ton of budget right from the start by doing proactive research and anticipating what irrelevant things people might search for.
Methods for Proactive Research:
- Brainstorming: Just sit down with your team and think. If you sell enterprise software, what’s the first thing you’d add? “free software,” obviously. List every term someone could use with the wrong intent.
- Competitor Analysis: Look at what your competitors offer that you don’t. If they have a budget product line and you’re premium-only, add their budget product names as negatives.
- Keyword Planner: Even though it’s mainly for finding positive keywords, the Google Ads Keyword Planner can show you related, tangential terms that you should exclude. Type in your core keywords and scan the suggestions for junk.
- Customer Service Inquiries: Talk to your support team. What weird questions do they get all the time that show a total misunderstanding of what you sell? These are often pure gold for new negative keyword ideas.
Editorial Aside: The “Hidden” Value
Most people think negative keywords are just about saving money. They do that, but they also force your ad relevance to get sharper, which often leads to lower CPCs and better ad positions because Google’s system rewards precision. When your ads only show for highly relevant queries, your Quality Score goes up. This is where a smart approach to your creative and keyword strategy really pays off. You’re creating a powerful feedback loop: filtering out bad traffic with negatives while your ad copy and landing pages perfectly match the intent of the good traffic. For some businesses, this is also where a mobile marketing agency like Moburst becomes a valuable partner. Their expertise in areas like App Store Assets helps ensure your visuals and descriptions are already optimized to attract the right users, which perfectly complements a tight negative keyword strategy.
5. Automate with Rules and Scripts
Once an account gets big enough, you physically can’t do a manual review of everything. It’s a massive bottleneck. This is where you can use Google Ads’ automation tools to help manage the workload.
Google Ads Automated Rules:
You can set up rules to do things like pause ad groups if they hit certain triggers. You can’t make a rule to “add a negative keyword” directly, but you can create rules that notify you or, more importantly, stop the bleeding. For example, you could set a rule like: “If an ad group’s cost goes over $50 in the last 7 days with 0 conversions, pause the ad group and email me.” It doesn’t add the negative for you, but it stops you from wasting more money on what is probably irrelevant traffic.
Google Ads Scripts:
For anyone comfortable with them, Google Ads Scripts are a much more powerful way to automate negative keyword management. You can find pre-written scripts online or write your own that can:
- Automatically find and add search terms as negatives if they have high costs and zero conversions.
- Identify conflicts where one of your negative keywords might be blocking a good, positive keyword.
- Generate custom reports on how your negatives are performing.
Example Script Logic (conceptual):
A typical script might query your Search Terms Report for the last 30 days, then filter for any term that’s spent over, say, $50 without a single conversion. It would then automatically add those losing terms to a specific shared negative list as a phrase match. This kind of automation is a huge time-saver, but it definitely requires careful setup and you have to monitor it to make sure it doesn’t do something you didn’t intend.
6. Monitor Negative Keyword Conflicts
While you’re adding negatives, you always run the risk of overdoing it and accidentally blocking traffic you actually want. This happens when a negative keyword is too broad and stops your ad from showing on a perfectly good, converting search query. It happens.
How to Identify Conflicts:
- Google Ads Diagnostics: Go to “Keywords” and then “Search keywords” in your account and check the “Status” column. If you see a keyword marked as “low search volume” or “rarely shown” when you know it should be getting traffic, a negative keyword might be the culprit.
- Negative Keyword Conflict Scripts: There are advanced Google Ads scripts built specifically to find these conflicts. They’ll compare your positive keywords against all your negative lists and flag any instance where an aggressive negative might be blocking a valuable term.
- Regular Review: Just do a periodic spot-check of your negative lists, especially your broad match ones. If you see a sudden, unexplained drop in impression volume for a whole campaign, it’s possible a broad negative went too far.
Common Mistake: Overlapping Negatives
Don’t create a mess. Adding “[blue shoes]” as an exact match negative is fine. But if you also have “shoes” as a broad match negative in a different list that’s also applied to that same campaign, you’ve created a redundant and confusing situation. Keep your lists clean. This isn’t a “set it and forget it” part of PPC. It’s a process of continuous optimization. But by using a tiered strategy, living in your search term reports, using shared lists, and layering in some automation, you can make your campaigns so much more efficient and ensure every dollar is working for you. Too many businesses still waste ad spend on terrible keyword targeting. Adopting these tactics will help you optimize for 2026 profit and make sure your AI paid media budget isn’t just evaporating.
What’s the real difference between negative broad, phrase, and exact match?
They control how restrictive your block is. Broad match negative blocks your ad if the search contains all your negative keywords, in any order. The term `running shoes` would block “shoes for running” and “running race shoes.” Phrase match negative blocks the search if it contains your exact keyword phrase, but it can have words before or after. The term `”running shoes”` would block “best running shoes” but it would not block “shoes for running.” Exact match negative is the most restrictive, it only blocks the search if it’s identical to your negative keyword, with no extra words. The term `[running shoes]` only blocks the query “running shoes.”
How often do I really need to check my Search Terms Report?
For any campaign with decent volume, you should be in there weekly. That frequency lets you catch and stop budget waste before it does real damage. If you have a very low-traffic campaign, you might get away with a bi-weekly or monthly check, but a consistent, weekly habit is the professional standard.
Can adding negative keywords actually hurt my campaigns?
Yes, absolutely, if you’re careless. Being too aggressive, especially with broad match negatives, can easily block relevant searches that would have converted. This leads to a drop in impressions and clicks from good potential customers. That’s why you have to periodically review your negative lists and check for conflicts with your positive keywords.
When should I use ad group vs. campaign level negatives?
It’s all about scope. If a term is bad for one ad group but could be fine for another one in the same campaign, add it at the ad group level. If the term is irrelevant for every ad group in that campaign, add it at the campaign level. And if the term is just junk for your entire account, across multiple campaigns, then you should use a shared negative keyword list to apply it everywhere at once.
What are some no-brainer negative keywords I should start with?
Some common buckets are competitor brand names (unless you’re specifically targeting them), terms related to “free” or “cheap” if you’re a premium service, and informational queries like “how to,” “what is,” or “examples” if your goal is purely sales. Also, always add job-seeking terms like “jobs” and “careers.” The most important thing is to tailor these lists to your actual business model.
