Setting up negative keywords in Google Ads is the most effective way to prevent your advertisements from showing on search terms related to products or services you do not offer. By identifying and excluding these unwanted search queries, you gain control over your advertising budget and improve your overall return on investment. This process acts as a filter for your traffic, ensuring that your campaigns target only the most relevant potential customers.
Why should you use negative keywords?
In a typical account, budget can be wasted on high-volume search terms that look relevant but do not convert for your specific business goals. For example, if you operate a shop that sells premium leather shoes, you do not want to pay for clicks from people searching for cheap rubber flip-flops. Negative keywords act as a protective barrier, stopping these mismatched clicks before they happen. This helps you keep your cost-per-acquisition low while focusing your resources on high-intent traffic.
Without a solid negative keyword strategy, Google Ads will rely on its broad matching logic, which can often misinterpret the intent behind a user’s search query. This misinterpretation leads to impressions on terms that are merely related to your industry but not your specific product line. By taking manual action to exclude these terms, you shift the balance back to your control, allowing you to prioritize the search queries that actually drive meaningful revenue for your business.
How do you identify which keywords to exclude?
The best place to start looking for negative keywords is the Search Terms report within your Google Ads account. This report shows you the actual queries users typed into Google that triggered your ads to appear. Reviewing this list on a weekly basis allows you to spot irrelevant patterns early. You should look for terms that are clearly outside your scope, such as ‘free’, ‘how to’, or ‘jobs’, if your goal is strictly to generate sales for a specific product.
Another common pattern is noticing branded terms from competitors that you do not want to associate with your own brand. If your budget is limited, spending money on broad search terms that trigger your ads for competitors’ names might not be the most efficient use of funds. Checking the search term report consistently provides the evidence needed to make informed decisions about what to add to your negative keyword lists.
What are the different types of negative keyword matching?
| Match Type | How it works | Best used for |
|---|---|---|
| Negative Broad | Excludes if all words are present | Broad exclusions |
| Negative Phrase | Excludes if the exact phrase is present | Specific multi-word phrases |
| Negative Exact | Excludes only that exact term | Very specific search queries |
Understanding how Google processes these match types is necessary for building a long-term strategy. Broad match negatives are the most restrictive; if you exclude the word ‘cheap’, your ad will not show for any search containing that word, regardless of order. Phrase match is more targeted, excluding only when the specific sequence of words appears in the query. Exact match is the most surgical, blocking only that single specific query, which is useful when you want to refine traffic without blocking too many potential leads.
How to set up negative keywords in the Google Ads dashboard?
- Go to your Google Ads account and select the campaign or ad group you want to modify.
- Click on the ‘Keywords’ menu item in the left-hand navigation pane.
- Select ‘Negative search keywords’ from the secondary menu.
- Click the plus button to add new terms manually.
- Choose whether to apply these to a specific campaign or an ad group.
- Type your chosen negative keywords, one per line, and click save.
For larger accounts, using negative keyword lists is a more efficient approach. Instead of managing keywords at the individual campaign level, you can create a shared list in the ‘Tools and Settings’ menu under ‘Shared Library’. Once created, you can apply this single list to multiple campaigns simultaneously. This ensures that if you decide to exclude a term like ‘free’ across your entire account, you only have to update it in one central location, preventing inconsistencies.
How Alien Road applies negative keyword strategies
At Alien Road, our approach centers on a consistent audit cycle to ensure client budgets remain focused on high-conversion paths. For a typical engagement, we begin by importing a base list of industry-standard negative keywords to prevent initial wasted spend on non-commercial queries. We then perform manual reviews of search term data every week to capture new variations and emerging irrelevant queries that appear as user behavior changes.
We also prioritize the use of shared lists to keep campaign structures clean. By maintaining a ‘Global Negative’ list, we can protect all active campaigns from terms that are universally irrelevant for the client, such as ‘career opportunities’ or ‘news articles’. This process allows us to focus our attention on analyzing search term trends rather than performing repetitive administrative tasks, ensuring that our efforts contribute directly to better campaign efficiency.
Common mistakes to avoid when adding negative keywords
- Over-blocking: Adding too many keywords that might actually result in relevant traffic.
- Using the wrong match type: Accidentally using broad match when you only intended to block a specific phrase.
- Ignoring search intent: Blocking a term because it has a low conversion rate without considering if it is an important top-of-funnel query.
- Failing to review: Setting up a list once and never updating it as search trends evolve over months or years.
Where to start this week
Begin your work this week by opening your Search Terms report for the last 30 days. Sort the list by the number of clicks or total spend to identify the most expensive non-converting queries. Once you have identified these, add the most clearly irrelevant terms as negative keywords. After that, schedule a recurring task to review these search terms every Friday to keep your account clean and your budget working for you throughout the next month.
Frequently Asked Questions
Should I add negative keywords at the campaign or ad group level?
Use the campaign level for terms that are irrelevant to your entire business, such as ‘free’ or ‘job’. Use the ad group level for more specific instances where a keyword might be relevant for one product but not another. This granular approach gives you maximum control over your traffic without sacrificing reach for your high-performing keywords.
How many negative keywords can I add?
Google Ads allows you to add thousands of negative keywords per campaign. However, it is better to prioritize quality over quantity. Focus on the terms that actually drain your budget or significantly lower your conversion rate. You do not need to add every possible variation of a bad term, as the system is often smart enough to identify related queries.
Will negative keywords affect my Quality Score?
Negative keywords generally help your Quality Score indirectly. By preventing your ads from showing for irrelevant searches, you reduce the number of low-intent clicks. This often leads to a higher click-through rate on the searches that do matter, which is a key component in Google’s calculation of your ad relevance and overall Quality Score.
Can I remove a negative keyword later?
Yes, you can remove negative keywords at any time. Simply navigate to the ‘Negative keywords’ section in your dashboard, select the term you wish to remove, and delete it. This is useful if you change your business offerings or if you find that a previously blocked term is now something you actually want to target in your future campaigns.
