How to Calculate Your Ad Return
Reported returns vary by industry and optimization quality; use the formula ROI = (Revenue – Ad Spend) ÷ Ad Spend with your contribution margin (not just revenue) to get a true profit picture.

PPC vs SEO: Which Is Better?
| Business Scenario | Recommended Approach | Why It Works |
| Speed Needed ≤ 14 Days | Bias PPC | PPC brings traffic as soon as your ads start running. This is perfect for quickly reaching your lead generation goals. |
| CAC Target < LTV ÷ 3 | Mix PPC and SEO. | Use PPC to achieve immediate lead targets while building SEO for long-term, lower-cost acquisition. |
| Brand Search Share < 40% | Invest in SEO. | If at least 40% of searchers click on your site for branded terms, build organic presence first. (depends on Google’s algorithm) |
PPC is your instant growth lever, and SEO is your compounding growth engine — most businesses benefit from combining both.
Benefits of Hiring a PPC Agency
Hiring an accomplished PPC marketing agency isn’t just about running ads — it’s about running profitable ads. Here are 4 reasons why businesses choose agencies instead of going solo.
1. Professional Strategy & Proven Process
Agencies do more than just set up ads — they use a clear growth plan.
- Onboarding Steps: Account audit → Keyword strategy → Campaign build → Launch → 14-day optimization cycle.
- Performance Tracking: Weekly performance reviews with cost-per-acquisition (CPA), return on ad spend (ROAS), and click-through rates (CTR).
2. Clear Pricing & Packages
No more guesswork. Expect clear pricing tiers based on your ad spend:
- Starter Plans: $1K–$3K monthly ad spend, perfect for small businesses.
- Growth Plans: $5K–$10K monthly spend for multi-location or scaling brands.
- Enterprise Plans: $20K+ monthly spend with advanced automation and audience segmentation.
Plus, most agencies charge 10–20% of ad spend as a management fee, so you know exactly where your money goes.

How Much Does PPC Cost?
The costs of pay-per-click (PPC) advertising depend on the industry, the level of competition, and the specific goals of the campaign.
- Google Ads average CPC: $1–$4 (varies by industry).
- Very competitive industries (finance, legal): $50+ per click.
- % of Ad Spend: Usually 10-20% of monthly ad spend.
- Performance-Linked – Lower base fee + bonus tied to hitting CPA or ROAS targets.
- Flat + % Hybrid – Base retainer + % of spend. Great for predictable service and scalable effort.
- Tiered Pricing — Flat fees at different spend ranges (e.g., $500 under $5k spend, $1k for $5–20k spend).
Example PPC Cost Table
| Monthly Ad Spend | Fee Model (15%) | Hybrid Model ($500 + 10%) | Total Monthly Cost |
| $3,000 | $450 | $500 + $300 = $800 | $3,450 – $3,800 |
| $10,000 | $1,500 | $500 + $1,000 = $1,500 | $11,500 |
| $50,000 | $7,500 | $500 + $5,000 = $5,500 | $55,500–$57,500 |
Is PPC Profitable for Small Businesses?
PPC can be very profitable — but only if key conditions are met. Treat it as an investment with measurable points:
Profitability Conditions
- Conversion Rate (CVR) Threshold: Your landing page converts ≥2–3% to make campaigns sustainable.
- Average Order Value (AOV): The higher your AOV, the more you can spend per click and still stay profitable.
- Margins: Your gross margin must cover ad spend, overhead, and agency fees.
- Payback Window: Aim to recover ad spend within 30–60 days, unless you have strong LTV.
- Learning Budget: Allocate at least 3× your target CPA as a test budget to exit the learning phase.
For local businesses, Google Ads campaigns and online advertising can significantly boost rankings in local search results, ultimately increasing foot traffic to your business.
Quick Breakeven Formula
Use this simple formula to check if PPC is worth testing:
Breakeven CPA ≤ (AOV × Margin × Conversion Rate)
Example:
If your AOV = $200, Margin = 50%, and CVR = 3%.
Breakeven CPA = $200 × 0.5 × 0.03 = $3.00.
If your actual CPA is below $3, PPC is profitable. If it’s higher, you need to optimize CVR, bids, or AOV before scaling.
How to Choose a PPC Agency
PPC advertising agencies are not the same, and selecting the wrong one can waste your budget instantly. Here’s what to look for when choosing the right PPC Advertising Agency:
Proven Case Studies
- Request at least 3 redacted client reports showing cost-per-lead (CPL), CPA, and ROAS trends over time.
- Look for before/after data — not just vanity metrics like impressions or clicks.
Clear Reporting
- Ask for a sample GA4 dashboard they use for clients.
- Confirm you’ll receive weekly or monthly reports with CPA, conversion rate, and spend breakdowns.
.
Full-Funnel Strategy
- Verify they handle conversion tracking setup and share UTM governance rules.
- Ask how they manage retargeting, LTV-based bidding, and experiment cadence (e.g., A/B tests per quarter).
Platform Expertise
- Ensure they have Google Ads certifications and experience with Microsoft Ads, display, and remarketing.
- Request to see the change logs from a live ad account to confirm they optimize weekly.
Collaborative Approach
- Confirm ad account ownership stays with you, not the agency.
- Request their onboarding checklist & SLA — see how fast they launch campaigns.
- Check if they provide a weekly QA checklist.
