Wondering whether your business could benefit from Google ads? Let’s look at Google Ads cost, some factors affecting the cost, and strategies for getting the most out of your budget for your Google Ads campaign.
What Google Ads does
Google is by far the dominant search engine in Australia, with more than 90 percent share of the market.
Google Ads targets your audience on the Google search network based on demographics, interests, and geographic location. Google then displays relevant search ads to your target audience on Search Engine Results Pages (SERP), YouTube, Gmail boxes, the Google Play Store, and Google Shopping.
Types of Google Ads campaigns
Google has nine campaign types. Each has different marketing goals, ad formats, and targeting options. The nine types are: Search ads, Display ads, Video ads, Shopping ads, App adds, Discovery ads, Local Services ads, Performance Max ads, and Smart ads.
Google Ads pricing
You pay each time someone interacts with your ad, based on different pricing models.
| Google Ads Pricing Model | You’re charged when … |
| Cost-Per-Click (CPC) | A user clicks on your ad |
| Cost-Per-Mille (CPM) | Your ad is displayed 1,000 times, regardless of clicks |
| Cost-Per-Acquisition (CPA) | A user does something, such as completing a purchase or submitting a form |
| Cost-Per-View (CPV) | A user views your video ad |
An auction system determines the actual Google Ads pricing you pay within each model.
Google Ads cost in Australia
In 2025, the average cost-per-click in Australia is between $2 to $4 AUD.
Australian businesses have a range of monthly Google Ads budgets. A small business may spend around $1,000 to $2,000 AUD per month. Larger businesses, or those in highly competitive industries, may spend anywhere between $5,000 all the way up to $20,000 AUD (or more) to maintain strong online visibility. Those monthly budgets are just for the ad spend and don’t include any management fees that you’ll pay if using a digital marketing ad group or agency.
Google does not have a set minimum daily budget for ad spending, but starting out at an average daily budget of $10 to $50 AUD will give you some meaningful data.
Factors influencing Google Ads auction system and cost
Industry competition
Highly competitive industries have higher average cost-per-clicks. In this benchmark study of industries in Australia, the industries that paid the highest average cost-per-clicks were automotive, hotels, and airlines for flights (with average cost-per-clicks ranging from $10.90 to $15.60 AUD). E-commerce was at the lower end of the cost scale (with average cost-per-clicks ranging from $2.50 to $5.00 AUD). Lowest in the study? The dating industry clocked in with an average cost-per-click of $1.70 AUD.
Keyword competition
Bidding on highly competitive keywords also drives costs up. Industries like insurance, legal services, and finance often have much higher cost-per-clicks (CPCs) because the keywords are so competitive, especially those that reveal high commercial intent and could drive conversions, like ‘apply for house loan’. The most expensive keywords in these industries can have CPCs of $50 AUD or more.
Search volume
Search volumes also affect keyword cost. Higher search volumes equal increased competition and thus higher costs.
Target audience
Using demographics, interests, or geographic location to target a specific audience can affect your average CPC.
Geographic location
Location may also affect your average CPC. Targeting denser populations or affluent localities can result in higher costs.
Seasonality
Imagine being in the travel industry and competing for a target audience during school breaks or over holidays. Seasonal events and holidays can drive up competition in some industries and therefore average CPCs.
Ad quality score
Google Ads determines your quality score based on your keyword relevance, ad relevance, and ad copy. Ads that closely match the intent of the user’s search receive a higher quality score. The ad’s Click-Through Rate (CTR) affects your quality score as well. Google rewards high-quality ads with lower CPCs and better ad placement.
Google Ads management fees
An important question in managing Google Ads budgets effectively: Should I pay someone else to do Google Ads management for me?
Google Ads campaigns require a lot of time to manage, particularly for those in competitive industries. A specialist in Google Ads management can help you develop a campaign strategy and ad budget. Google Ads management services can include campaign setup and keyword research, along with ongoing monitoring and optimisation. Generally, the costs are included for any additional tools and integrations needed for campaign optimisation.
Google Ads management fees vary based on the complexity of the Google Ads campaign, the number of services offered, and the agency’s experience. The fee can range from $800 to 2,500 per month. Agencies may charge Google Ads management fees as a percentage of the ad spend or as a 3-month fixed rate.
Managing Google Ads budgets wisely
Define your target audience
The first strategy is to define your target audience as precisely as you can. That makes sure your ads reach the most relevant audience, making them cost-effective.
Do keyword research
Use Google Keyword Planner on your Google Ads account to help create your keyword list. With Google Keyword Planner, you can identify relevant keywords that are less competitive, which helps lower the overall cost.
Use long tail keywords. These are typically phrases of three words or more. They are more specific than the highly competitive keywords and so have lower search volumes, making them less competitive. For example, instead of bidding on ‘photography studio,’ try ‘nearby Canberra photography studio’. With long tail keywords, you can reach a relevant audience at a lower cost.
Also use negative keywords, which filter out irrelevant keywords and traffic. Negative keyword research finds specific words or phrases to avoid. This way, your ads won’t show up in irrelevant searches.
Continue to review and refine your keyword list.
Create a campaign and monthly budget
Define the objectives of the ad campaign clearly. How will you measure success? Are you looking at clicks? Conversion? Revenue?
Develop a realistic budget and consider daily or monthly spending limits.
Start with a test campaign
Dip your toes into the water of Google Ads with a test campaign. Assess ad relevance by trying out different headlines, presentation methods, and ad copy. The results will show you clearly what your audience wants.
Use bidding strategies to your advantage
In the Google Ads auction process, there are different bidding strategies.
Manual bidding on CPC lets you set how much you’ll pay for each click. This is ideal for those doing their own Google Ads management.
If you want to reduce the time and effort involved in managing bids, then consider automated bidding strategies. Algorithms adjust the bids automatically to maximise chances of reaching your defined performance goals. Those goals might be the maximum number of clicks, a targeted Cost-Per-Action, a targeted Return-On-Ad-Spend (ROAS), or the maximum number of conversions or conversion value.
Smart bidding strategies are part of automated bidding. In smart bidding, Google’s AI considers factors such as device, time of day, and location to optimise conversions in real time.
Target timing, location, and devices
The timing of when your ads appear can affect costs and effectiveness. Use ad scheduling to time your ads to appear when your audience is most active and likely to see them.
Target the geographic areas where your customers are. This keeps you from spending on clicks in geographic areas where you’re less likely to have conversions.
Target devices as well for cost-effectiveness. For instance, if you’re seeing better conversion rates from users on mobile phones, then allocate more of your budget to mobile ads.
Optimise like crazy
Continue to refine your keywords list. And don’t forget to optimise landing pages for the best user navigation and landing page experience. Continuing to optimise content as well will improve the quality scores of your ads.
Examine Google Ads ROI
How do you know if your Google Ads campaign is cost-effective? There are a few metrics you can use to gauge the overall effectiveness of your ad campaign.
Look at cost of acquisition (CPA), however you’re defining that cost. Your target CPA may be in terms of purchases, signups, or downloads. Look at that cost versus the lifetime value of the customer.
Assess Click-Through Rates (CTR). Higher click-through rates probably indicate that your ads are relevant and engaging. That may mean higher ad quality scores, which result in lower costs and better ad placement.
Continue to monitor the campaign’s performance metrics and adjust accordingly to maximise cost effectiveness.
Is Google Ads worth it?
The simple answer is yes. Google Ads gives you instant online visibility, and since it targets a relevant audience, Google Ads drives more traffic to your website quickly.
You can see and measure the results on the platform. That lets you track results and adjust your ad campaign accordingly.
Is Google Ads better than SEO?
This question is comparing apples to oranges. Google Ads results in more website visitors immediately. SEO campaigns lead to organic growth over time of more website visitors. These strategies work well in tandem, so combine both for the best results.
How long does it take to see results with Google Ads?
Prepare to wait a few weeks to a few months. The Google algorithm will need a few weeks to learn. It gathers data related to its bidding strategies and re-calibrates its bidding decisions to maximise performance results.
Remember to be patient. It takes about three months for a campaign to mature, and this time allows you to adjust as needed to optimise the campaign.
