All About Google Ads’ Negative Keywords
August 13, 2020

Negative keywords are keywords that you want to
exclude from your campaign.

If these keywords are included in the search query, your ad will not show. Negative keywords are commonly left out of the setup process and can cause a lot of irrelevant traffic and wasted spend. We find that a lot of campaigns that are created by non-Google Ads professionals, or those created with the help of Google’s assistance typically don’t have negative keywords in place. 



Further to this, these campaigns typically use broad match keywords which puts the campaign at even greater risk of high wasted spend. In this article, we’ll explain where you can use negative keywords, how they work and some examples that you might want to include in your search campaigns.



How to Use Negative Keywords

With a Google Search campaign, you are able to appear in front of anyone who does a Google Search and that opens up a lot of room for error and variety! Negative keywords should be added during campaign set up. This ensures that you are excluding irrelevant search terms from the get-go. You should also constantly monitor your search term report and continue to update your negative keywords as you see irrelevant search terms to ensure you are constantly refining your campaign, making it more relevant to future traffic.

If you are using broad match keywords, broad match modifiers, phrase match, or even exact match (although to a lesser degree), you should be using negative keywords. The broader your keywords (i.e. short tail, single-word keywords or broad match type keywords) the more risk your campaign has of appearing for irrelevant keywords.


When building your negative keyword list, you want to think of common words that might be associated with your keywords but aren’t actually relevant to your campaign. We’ll offer some common negative keywords further along in this post.



A note on spellings and variations:

One of the biggest differences between negative keywords and positive keywords is that you will need to add misspellings, variations, synonyms and plurals as negative keywords if you want to exclude them.

Where Can I Use Negative Keywords

Negative keywords can be used in a range of campaign types. 

Google Search

You can use broad match, phrase match and exact match keyword match types, however, these work a little differently to positive keyword match types. We’ll explain further below.


Google Shopping

You can use negative keywords to specify search terms you don’t want your shopping ads to appear for, despite not having targeted keywords in the campaign. This can be extremely useful if your products are appearing for unrelated searches.


Google Display & Video Ads

These will be excluded as an exact topic. If the page is strongly related to the topic or contains the topic, your ads won’t show. You can also use other exclusion targeting methods with Display and Video to further control the content and websites your ads appear on (we highly recommend this!)



Negative Keyword Match Types

Also, negative keywords can also use broad match, phrase match and exact match types. So if you want to exclude an exact search term, use exact match. If you want to exclude one word completely, use a broad match. Negative keywords do not use broad match modifier match types. Here’s a breakdown of the different match types for negative keywords.

Broad Match

The default setting for negative keywords is broad match. If you add a negative broad match keyword, all queries that contain all words within the negative keyword will be excluded, however, if a search term matches with only one of the words in the negative keyword, it will still show.


Let’s look at an example. 

Negative keyword: blue shirt

Search Term Could your ad show?
Blue stripey shirt No
Black shirt Yes
Blue shirt No
Blue shirts Yes

Phrase Match
With phrase match negative keywords, your ad won’t show if the search contains the exact keyword terms in the specified order. Other words can be used in the search, but if the negative keyword appears anywhere in the search query in the order specified by the phrase match keyword the ad won’t show.


Let’s look at an example. 

Negative keyword: "blue shirt"

Search Term Could your ad show?
Red and blue shirt No
Blue and red shirt Yes
Blue shirt No
Shirt blue Yes

Exact Match
With exact match negative keywords, your ad won’t show if the search query contains the exact keyword, in the same order and without any extra words within the phrase.

Let’s look at an example. 

Negative keyword: [blue shirt]

Search Term Could your ad show?
Red and blue shirt Yes
Blue Shirts Yes
Blue shirt No
Shirt blue Yes

Common Negative Keywords

There are some keywords that we apply to almost all Google Search Campaigns. For example. a lot of people look to study or get a job in particular industries so it’s important to exclude potential words related to studying or working in a field. Some of these common negative keywords include free, cheap, courses, salary, and wages. 

Other great negative keywords include research-based keywords like ‘how-to’, ‘how can’, ‘what do’, where relevant. Each campaign and business will have different negative keywords based on the products and services they offer. Other common negative keywords include adult-related content, such as ‘porn’, ‘nude’, ‘xxx’ because you are dealing with the general public and you just want to be sure you’ll never show for anything like that!


Conclusion

Negative keywords are an important component of Google Ads campaigns and can save you lots of money when utilised. It’s important to keep your negative keyword list updated over time based on search traffic so your campaign is as relevant as possible to your search traffic.



Use match types to get the most out of your keywords, and don’t forget to include negative keywords in your campaign from set up to give it the best chance of success from the start.

The Client AGA Air Conditioning is a Canberra-based heating and cooling specialist delivering residential and commercial installation, servicing and maintenance across the ACT. AGA had built a strong reputation through quality workmanship, referrals and customer service. What it needed was a digital and acquisition sy stem that matched the standard of the business and its growth ambitions, one built to support serious, sustained investment rather than one-off campaign spend. PupDigital was engaged in a multi-year partnership to bring the website, conversion tracking and paid media strategy together into a single, connected acquisition system. The Challenge AGA was already a trusted local provider, but its website and advertising weren't working together as one system. The site needed to better communicate the quality of the business and give prospective customers a clearer path to enquire. At the same time, the advertising account needed to become far more commercially disciplined. Heating and cooling demand shifts significantly through the year, and customer intent moves quickly between installation, servicing, evaporative cooling and gas heating, each with different commercial value. Residential and commercial enquiries needed to be treated differently, and the business's own capacity to take on work had to be factored into how aggressively the account was scaled. It's the kind of complexity we see all the time working with trades, services, and building and construction businesses. It's genuinely where we do our best work. A broad, static campaign was never going to cut it here. The goal wasn't more traffic, it was a system that turned demand into real, valuable enquiries, built to scale as the business did. Our Strategic Approach 1. Rebuild the Conversion Experience The first priority was improving what happened after someone clicked an ad. PupDigital designed and developed a new website that better reflected AGA's positioning and made its services easier to understand, with: Clearer service pathways for residential and commercial customers Improved mobile usability and more direct calls to action Tighter alignment between ad campaigns and the landing pages they led to Simplified enquiry journeys The website was built as part of the acquisition strategy, not a separate branding exercise. Every campaign needed to send customers to a page that matched their intent and made the next step obvious. 2. Improve the Quality of the Data Better optimisation depends on measuring the right things. PupDigital strengthened conversion tracking across the site and ad account, including enquiry forms and tracked phone calls, and critically, stopped treating every conversion as equal. AGA's feedback made clear that phone calls often represented stronger opportunities than lower-intent web actions. Tracking and optimisation were refined accordingly, shifting the strategy away from simply increasing reported conversions and towards improving the quality of the enquiries being generated, the metric that actually matters to a business owner's bottom line. 3. Structure Campaigns Around Demand and Commercial Value Rather than one broad, always-on campaign, PupDigital structured the account around AGA's core service categories and how demand moved seasonally, giving granular control over which services were promoted, how budget was allocated, and the messaging and landing pages each audience saw. This meant investment could be increased where strong opportunities existed, pulled back where intent was weaker, and kept continuously aligned with the work AGA actually wanted to win, not just the work that was easiest to generate leads for. Scaling Investment With Confidence As performance and enquiry consistency improved, PupDigital progressively scaled AGA's monthly ad investment, growing it 300% over the course of the partnership. This wasn't a case of increasing spend and hoping volume followed. Every scaling decision was informed by conversion performance, search demand, lead quality feedback, seasonal opportunity, and AGA's real capacity to service new work. Growth in ad spend only compounds when the wider system, website, tracking and campaign structure, can convert that investment efficiently. Building that system first is what allowed AGA to keep increasing investment with confidence, rather than second-guessing where the budget was going. The Results Following the website launch in May 2025, AGA's Google Ads performance improved substantially against the preceding period: Conversions up 14% 18.71% conversion rate, a 77% improvement Impressions up 22% Monthly ad investment scaled 300% across the partnership The standout result was conversion rate, not raw traffic volume. The campaigns didn't need to chase the largest possible audience. They became more focused on reaching people actively searching for AGA's services and directing them into a stronger website experience. The result was a materially higher percentage of visitors taking meaningful action, a more efficient acquisition system, not just a busier one. Broader Business Growth: A Harvey Norman Commercial Contract Throughout the partnership, AGA continued expanding its residential and commercial workload, including securing a significant commercial contract with Harvey Norman Commercial, alongside a growing volume of rough-in and fit-off work. Landing a contract like that comes down to the quality of AGA's work and reputation, not an ad campaign in isolation. What it does show is the broader trajectory of the business during our partnership, and the part PupDigital played in making sure AGA's digital presence could keep up with, and represent, that scale of growth. Winning commercial-level work like this means having a website and digital presence that looks and performs the part, and that's what we focused on throughout. The Business Impact The most valuable outcome wasn't any single campaign result or website metric. AGA moved from a fragmented digital setup to one connected system for attracting and converting customers, and gained: A website that reflects the quality and scale of the business Clear visibility over what's actually driving enquiries, not just what's easy to report Granular control over service-specific and seasonal demand Confidence to keep increasing investment because the system converts it efficiently A digital foundation that supported the business's move into larger commercial work This is the throughline in how PupDigital works with trades, services, and building and construction businesses: advertising is never managed in isolation. It's shaped by the type of work a business wants, the enquiries it actually values, and the capacity it has to deliver, because that alignment, not spend for its own sake, is what drives real business growth. Conclusion AGA Air Conditioning shows what's possible when a website, tracking and paid media strategy are treated as one connected system, working together, rather than three separate pieces bolted on side by side. PupDigital's role was never simply to drive more clicks. We rebuilt the customer journey, strengthened measurement around what actually matters, aligned campaigns with seasonal and commercial priorities, and built a structure capable of supporting significantly increased investment, investment AGA could scale with confidence because the underlying system was built to convert it. The result: a 77% improvement in Google Ads conversion rate, a 300% increase in monthly ad investment, and a stronger digital foundation that helped support AGA's move into larger-scale commercial work.
