How Much Should I Spend on Google Ads per Month?
Most businesses should spend a minimum of $1,000–$3,000 per month on Google Ads to generate meaningful Search traffic, with SMB sweet spots at $3,000–$15,000 monthly. Your ideal budget depends on keyword CPCs in your industry (ranging from $1–$50+), target conversion volume, and competition level. Use Google’s Keyword Planner to estimate costs for your specific keywords and geography.
How Do I Calculate My Google Ads Budget?
Calculate using this formula: Monthly Budget = (Target Monthly Leads ÷ Conversion Rate) × Average CPC. For example: if you want 50 leads monthly, your landing page converts at 5%, and average CPC is $5 — you need 1,000 clicks × $5 = $5,000/month. Add 20% for testing and optimization ($6,000 total). This formula gives you a data-driven starting point rather than an arbitrary number.
What Are Typical Google Ads Costs by Industry?
| Industry | Avg CPC | Avg CVR | Avg CPL | Min Monthly Budget |
|---|---|---|---|---|
| E-commerce | $1–$3 | 3–5% | $20–$100 | $1,500 |
| B2B SaaS | $5–$15 | 2–4% | $125–$750 | $3,000 |
| Legal services | $15–$50 | 3–6% | $250–$1,670 | $5,000 |
| Healthcare | $5–$15 | 3–5% | $100–$500 | $3,000 |
| Home services | $8–$25 | 5–8% | $100–$500 | $2,000 |
| Real estate | $3–$10 | 2–4% | $75–$500 | $2,000 |
| Education | $3–$8 | 3–5% | $60–$270 | $1,500 |
| Finance/Insurance | $10–$50 | 2–4% | $250–$2,500 | $5,000 |
These are averages — your actual costs depend on geographic targeting, keyword selection, and Quality Score. Higher Quality Scores (7+) can reduce CPCs by 30–50% below industry averages.
How Should I Allocate My Google Ads Budget?
Allocate 50–60% to non-brand Search (your primary growth driver), 10–15% to brand Search (protecting your brand terms), 20–30% to Performance Max or Shopping (if e-commerce), and 5–10% to remarketing Display. New accounts should start with Search only and add Performance Max after accumulating conversion data. Never spread budget across too many campaigns — each campaign needs enough daily budget to generate meaningful clicks and conversions for optimization.
When Should I Increase My Google Ads Budget?
Increase when three conditions are met: your campaign’s impression share is below 80% (you are missing available searches due to budget limits), ROAS or CPA is consistently meeting targets for 14+ days, and your daily budget is exhausting before the end of the day (indicated by “Limited by budget” status). Increase by 15–20% every 7–10 days rather than making large jumps. Monitor the Search Impression Share metric — every percentage point of missed impression share represents potential conversions you are not capturing.
Should I Split Budget Between Google and Facebook?
Yes — Google captures active demand (people searching for solutions) while Facebook generates demand (reaching people before they search). A common allocation: 50–60% Google / 40–50% Facebook for direct response, 30–40% Google / 60–70% Facebook for brand building. The optimal split depends on your business — test both platforms and compare cost per acquisition across channels.
