What is Google Ads?
🎯 Pay-Per-Click Advertising
Google Ads (formerly Google AdWords) is Google's advertising platform where businesses pay to display ads in Google Search results, YouTube, Gmail, and millions of partner websites. You only pay when someone clicks your ad (PPC/CPC model) or views it (CPM model). Costs vary significantly based on industry, competition, keywords, and quality score.
- Set Your Budget: Determine daily/monthly spending limits based on business goals.
- Estimate CPC: Research average cost-per-click for your industry and keywords.
- Calculate Clicks: Clicks = Budget ÷ Average CPC.
- Project Conversions: Conversions = Clicks × Conversion Rate.
- Calculate ROI: Compare revenue from conversions vs. total ad spend.

Frequently Asked Questions
There's no minimum spend. You set your own budget. Average CPC ranges from $0.50-$50+ depending on industry. Most small businesses spend $500-$3,000/month. You only pay when someone clicks (or views for display/video).
"Good" CPC depends on your conversion rate and profit margins. If you make $100 profit per sale with 5% conversion rate, a $5 CPC is excellent (CPA = $100, 0% margin). Lower is generally better, but focus on CPA and ROAS, not just CPC.
Quality Score (1-10) measures ad relevance, landing page experience, and expected CTR. Higher scores = lower costs and better positions. Aim for 7+ on branded keywords and 6+ on generic keywords.
Target ROAS varies by business model. E-commerce typically aims for 4:1 to 10:1 (400-1000%). SaaS/B2B with recurring revenue may accept 2:1 initially. At minimum, ROAS should cover your cost of goods plus profit margin.
Ads can appear within 24 hours. However, optimization takes 2-4 weeks. Google's algorithm needs ~30 conversions to optimize effectively. Full campaign maturity typically takes 3-6 months of consistent spend.
Search Ads show when people search keywords (high intent, higher CPC, better conversion). Display Ads show on websites/apps (lower intent, lower CPC, good for awareness). Most start with Search, then add Display for remarketing.
CPC = Cost Per Click (what you pay each click). CPA = Cost Per Acquisition (total cost ÷ conversions). CPA = CPC ÷ Conversion Rate. CPA is more important for ROI since it shows actual cost per customer.
Smart Bidding (Target CPA, Target ROAS, Maximize Conversions) works well with 30+ monthly conversions. For new campaigns or low volume, start with Manual CPC or Maximize Clicks, then switch after collecting data.
Common reasons: competitive industry, low Quality Score, broad targeting, irrelevant keywords, poor landing pages, or bidding strategy issues. Check Search Terms report, add negative keywords, and improve ad relevance.
Google Ads captures intent (people searching for solutions). Facebook/Meta captures attention (targeting interests/demographics). Google usually has higher CPC but better conversion rates. Many businesses use both for different funnel stages.
