How Google Ads Billing Works: Essential Models
Google Ads operates on an auction system. When someone searches for a keyword, Google instantly runs an auction to determine which ads to show and in what order. Your “bid” is a part of this, but it’s not the only factor. How you’re charged depends on your campaign goals
The Google Ads Auction System
Google evaluates countless signals to determine ad placement and cost. This process considers your Bid, Quality Score, and the expected impact of your ad extensions. The goal is to provide the best user experience while giving advertisers a fair chance to reach their audience.
So, how does Google Ads charge for advertising? Principally, there are 3 models you should know, as follows:
Cost Per Click (CPC)
Cost Per Click (CPC) is the most common billing model and the core of Google Search ads. You are charged only when a user clicks on your ad, regardless of how many times it is displayed.
- When to use: Ideal for businesses that want website traffic, lead generation, or to drive sales.
- Business Examples: Online stores wanting people to view products, companies wanting users to fill out contact forms, or service businesses wanting people to click to call.
Cost Per Mille (CPM - Cost Per Thousands Impressions)
Cost Per Mille, or CPM, is a model that charges based on the number of ad impressions per 1,000 times (“Mille” is Latin for 1,000), whether a click occurs or not.
- When to use: Ideal for campaigns focused on Brand Awareness or making a brand widely known, such as ads on the Google Display Network or YouTube.
- Business Examples: New brands wanting to build recognition or movies wanting to promote a trailer to a large audience.
Cost Per Action (CPA - Cost Per Acquisition)
specific “action” you have defined (such as a purchase, membership sign-up, app download, or form submission). This is the primary goal of Performance Marketing, which Convert Cake specializes in.
- When to use: Ideal for businesses that want tangible results and are ready to pay for actual “Conversions.”
- Business Examples: E-commerce businesses wanting sales, online course platforms wanting new members, or real estate businesses wanting leads from interested buyers.
Comparison Table of Google Ads Billing Models
Model | Description | Best For | Pros | Cons |
CPC | Pay per click | Traffic, Leads, Sales | Pay only for interest | Click quality varies |
CPM | Pay per 1,000 views | Brand Awareness | Massive reach | Lower direct conversion |
CPA | Pay per action | Conversions, Sales | Tangible results | Needs sufficient data |
Key Factors Influencing Your Google Ads Costs
Efficient budgeting is about managing the variables that affect ad pricing. Convert Cake summarizes the essentials:
1. Keyword Competition
The more businesses bidding on a particular keyword, the higher its cost. Highly popular or generic keywords (e.g., “digital marketing,” “hotel Bangkok”) tend to be more expensive due to intense competition. Conversely, long-tail keywords (more specific phrases like “affordable boutique hotel Sukhumvit 24”) typically have lower competition and thus lower costs, often attracting more qualified leads.
2. Ad Quality (Quality Score)
Google wants to provide the best user experience, so it rewards relevant, high-quality ads. Your Quality Score (QS) is Google’s assessment of the relevance of your keywords, ads, and landing pages to a user’s search query. A higher Quality Score means:
- Lower Cost Per Click (CPC).
- Better ad positions.
- More impressions. By improving your Quality Score, you can significantly reduce your ad spend while gaining better visibility.
3. Campaign Type
Google Ads offers various campaign types, and each has a different cost structure and competitive landscape:
- Search Network: Text ads on Google search results; generally higher CPC due to high intent.
- Display Network: Image/video ads on websites and apps; generally lower CPM/CPC, good for awareness.
- Video (YouTube): Video ads on YouTube; often cost-per-view (CPV) or CPM, great for brand building.
- Shopping: Product listings for e-commerce; highly visual, performance-driven.
- App Campaigns: Promoting mobile apps; cost per install (CPI) or in-app action. Your choice of campaign type will directly impact your overall spend.
4. Targeting
Targeting specific geographic areas or times of day can influence your costs. Advertising in high-density commercial areas or during peak shopping hours might lead to higher competition and higher bids. Conversely, precise targeting can help you avoid wasting budget on irrelevant audiences, ultimately reducing your cost per conversion.
6. Industry Benchmarks
Some industries inherently have higher Google Ads costs due to their competitive nature, high customer lifetime value, or regulatory requirements. Industries like legal services, finance, insurance, and medical tend to have much higher average CPCs than, say, retail or arts and entertainment. Understanding your industry’s benchmark can help set realistic expectations.
How to Set Your Google Ads Cost Appropriately for Your Business
The questions “How much should I set for a Google Ads budget?” or “What is a good starting budget for Google Ads?” are priorities for many businesses, especially SMEs. Convert Cake recommends the following guidelines:
Google Ads Cost Daily vs. Monthly Management
Google Ads allows you to set either a daily or a monthly budget.
- Daily Budget: Offers more granular control, ideal for day-to-day adjustments. Google might spend up to twice your daily budget on any given day, but will balance it out over the month so that your average daily spend matches your set budget.
- Monthly Budget: Provides more flexibility for Google’s algorithms to optimize performance across the month, potentially leading to better results by allowing for higher spend on high-performing days.
Goals-Based Google Ads Cost: The Smart Approach
Instead of randomly picking a budget, work backward from your business objectives:
- Define your desired conversions: How many leads, sales, or sign-ups do you need?
- Determine your target CPA/CPL: What is the maximum you’re willing to pay for each conversion while remaining profitable? (e.g., if a sale generates 1,000 THB profit, and you want a 50% profit margin, your target CPA is 500 THB).
- Estimate required clicks/impressions: Based on your historical conversion rates (or industry averages), how many clicks/impressions do you need to achieve your desired conversions?
- Calculate total budget: Multiply your target CPA/CPL by the number of desired conversions. Alternatively, multiply estimated clicks by your expected CPC.
Example:
- Goal: 100 new leads per month
- Target CPL (Cost Per Lead): 500 THB
- Minimum Monthly Budget = 100 leads * 500 THB/lead = 50,000 THB
This approach ensures every baht spent is tied directly to a measurable business outcome. At ConvertCake, our growth marketing strategies begin with understanding your specific business goals to help you define and optimize your budget for maximum impact.
Starting Budget for SMEs
For small to medium-sized enterprises (SMEs) in Thailand, a common starting point for a Google Ads budget might range from 10,000 THB to 30,000 THB per month. This allows enough spend to gather meaningful data and begin optimizing without overcommitting. The exact amount will depend heavily on your industry’s competition and your specific goals.
The Power of Test & Iterate
Digital marketing is an iterative process. Start with a conservative budget, monitor performance closely, and then gradually increase your spend as you see positive results and a clear ROI. This phased approach minimizes risk and allows you to optimize your campaigns based on real-world data.
Comparison Table for Setting a Google Ads Budget
Desired Goal | Estimated CPA/CPL | Required Conversions | Recommended Minimum Budget |
20 Leads | 250 THB/Lead | 20 | 5,000 THB/Month |
50 Leads | 150 THB/Lead | 50 | 7,500 THB/Month |
100 Sales | 300 THB/Sale | 100 | 30,000 THB/Month |
Strategies to Reduce Google Ads Costs and Boost Performance (AI-Powered Insights)
To make Google Ads effective and economical, you must employ smart strategies and continuously optimize your campaigns. Convert Cake, an Ads Agency specializing in Performance Marketing, offers the following methods to reduce your Google Ads costs while increasing efficiency:
1. Optimize Your Quality Score Relentlessly
This is perhaps the single most impactful factor for reducing costs.
- Improve Ad Relevance: Ensure your ad copy directly relates to your keywords and the user’s search intent.
- Enhance Landing Page Experience: Your landing page must be relevant, user-friendly, fast-loading, and provide a clear, compelling call to action.
- Refine Keyword Selection: Focus on specific, high-intent keywords rather than broad, generic ones.
2. Master Negative Keywords
Don’t pay for irrelevant clicks! Negative keywords prevent your ads from showing for search terms that don’t align with your offerings. For example, if you sell new cars, you’d add “used,” “second-hand,” or “rental” as negative keywords to avoid showing your ads to people looking for those options. This eliminates wasted spend immediately.
3. Precision Audience Targeting
Go beyond just keywords. Leverage Google’s robust targeting options:
- Demographics: Target by age, gender, parental status, income (where available).
- Interests & Behaviors: Reach users based on their online interests and purchase intent.
- Custom Audiences: Create audiences based on specific URLs visited, apps used, or interests relevant to your business.
AI-Powered Insights for Precision: Just as our AI-powered nano-influencer scaling tools help clients like you reduce costs by up to 50% while enhancing authenticity through precise influencer selection, applying data-driven insights to audience targeting in Google Ads helps you reach the most relevant users, dramatically lowering your Cost Per Click (CPC) and improving conversion rates.
4. Optimize Your Landing Page
A high-converting landing page is crucial. Even the best ad will fail if the page it directs users to is slow, confusing, or doesn’t deliver on the ad’s promise.
- Load Speed: Crucial for user experience and Quality Score.
- Clear Value Proposition: What problem do you solve?
- Intuitive UX: Easy navigation, mobile-friendly design.
- Strong Call to Action (CTA): Tell users exactly what to do next.
5. Embrace A/B Testing
Never assume your first attempt is the best. Continuously test different versions of your:
- Ad Copy: Headlines, descriptions, CTAs.
- Keyword Match Types: Broad, phrase, exact.
- Landing Pages: Design, copy, images. A/B testing helps you identify what resonates most with your audience, leading to better performance and lower costs.
6. Leverage Automated Bidding Strategies
Google Ads offers powerful automated bidding strategies that use machine learning to optimize bids in real-time based on your specific goals:
- Maximize Conversions: Automatically sets bids to get the most conversions within your budget.
- Target CPA: Aims to get as many conversions as possible at or below your target cost-per-action.
- Target ROAS (Return On Ad Spend): Prioritizes conversion value to help you achieve a specific return on ad spend. These strategies can often outperform manual bidding by reacting instantly to auction signals.
7. Continuous Data Analysis and Real-time Reporting
Tracking and improving campaigns with data is the heart of marketing. Convert Cake emphasizes transparent ROI reporting through real-time dashboards, allowing you to see budget performance immediately.

FAQ
1. What is Budget Overspend, and why does Google exceed my daily limit?
Google may spend up to 2x your daily budget if the AI detects high-quality traffic. However, your total monthly bill will never exceed your “daily budget x 30.4 days.” This is an automated mechanism to capture peak search opportunities.
2. Why is the #1 ad position not always the most profitable (ROI)?
Ranking #1 often carries a premium price due to aggressive bidding. Frequently, positions #2 or #3 yield similar conversion rates at a significantly lower cost, resulting in a much healthier overall ROI.
3. Is Competitor Conquesting (bidding on rival brand names) more expensive?
Yes. Your Quality Score for a competitor’s brand is naturally low, forcing you to bid higher to appear. However, it is a powerful tactic to intercept high-intent customers at the final decision stage.
4. Can I prevent "Click Fraud" or competitors clicking my ads maliciously?
Google automatically filters invalid clicks and issues credits. However, an Ads Agency adds an extra layer of protection through IP Exclusion and third-party tools to block bots or repetitive manual clicks more effectively.
5. Why did my high-performing campaign suddenly drop in efficiency?
This is often Ad Fatigue, where your audience becomes unresponsive to the same creative over time, or competitors have raised their bids. Refreshing your creatives and real-time monitoring are essential to sustaining performance.
