Key Google Ads Concepts
KeywordsRequired
The search terms that trigger your ads. Choose carefully - too broad wastes money.

Exact (most targeted), Phrase, Broad (least targeted). Start with Exact/Phrase.

Google's rating of ad relevance. Higher score = lower costs, better positions.
Negative KeywordsRequired
Terms you DON'T want to show for. Essential for controlling spend.
Landing PagesRequired
Where clicks go. Must match ad promise. Directly impacts conversions.
Focus on keywords that show buying intent:
- Good: "plumber Sandton emergency", "buy running shoes online SA"
- Bad: "plumbing", "running shoes" (too broad, expensive)
Add "near me", "buy", "hire", "price" modifiers for better intent.
Meta Ads (Facebook/Instagram)

Creating Effective Ads
Ad Copy Best Practices
Lead with BenefitRequired
What's in it for them? Start with the outcome, not features.
Include a Clear CTARequired
Tell people exactly what to do: Shop Now, Get Quote, Learn More.
Create UrgencyRequired
Limited time offers, stock quantities, deadlines drive action.
Use Social ProofRequired
Reviews, customer count, testimonials build trust.
Match Landing PageRequired
Ad promise must match landing page. Disconnects kill conversions.
Visual Best Practices
Images:
- Use high-contrast colors (stand out in feed)
- Show people using product (relatable)
- Minimal text (Meta limits text on images)
- Mobile-first dimensions (1:1 or 4:5)
Videos:
- Hook in first 3 seconds (before skip)
- Design for sound-off (captions essential)
- Keep under 30 seconds for feeds
- Vertical format for Stories/Reels
Ad Formulas That Work
- Problem-Agitate-Solution: State problem → intensify it → present your solution
- Before-After-Bridge: Their current state → desired state → your product bridges gap
- Social Proof: "Join 5,000+ SA businesses who..."
- Direct Benefit: "Save 3 hours a week on [task]"
Testing & Optimization
A/B Testing Basics
Test One Variable at a Time:
- Headlines: Different benefits, questions vs statements
- Images: Product vs lifestyle, different colors
- Audiences: Different interests, demographics
- CTAs: Shop Now vs Learn More vs Get Started
- Offers: Discount vs free shipping vs bonus item
Testing Rules:
- Run tests for at least 3-5 days
- Need 100+ conversions for statistical significance
- Don't change multiple things at once
- Document everything (what worked, what didn't)
Optimization Checklist
Check Daily (First Week)Required
Monitor spend, CTR, CPC. Catch problems early.
Kill UnderperformersRequired
If an ad has 0 conversions after 1,000 impressions, pause it.
Double Down on WinnersRequired
Increase budget on ads with good ROAS. Scale gradually.
Refresh CreativeRequired
Ad fatigue is real. Rotate new creative every 2-4 weeks.
Review Search Terms (Google)Required
Check what searches triggered your ads. Add negatives for irrelevant ones.
Common Mistakes to Avoid
- No Tracking: Running ads without conversion tracking = wasting money. Set up tracking first.
- Too Broad Targeting: "All South Africans 18-65" is not targeting. Be specific.
- Expecting Instant Results: Algorithms need 50+ conversions to learn. Give it time.
- Not Testing: First ad rarely wins. Plan to test multiple versions.
- Poor Landing Pages: Great ads + bad landing page = no conversions.
- Ignoring Mobile: 70%+ traffic is mobile. Design for mobile first.
- Set and Forget: Ads need ongoing optimization. Check weekly minimum.
- Copying Competitors: What works for them may not work for you. Test your own.
Measuring Success
Essential Metrics
Awareness Metrics:
- Impressions (how many saw your ad)
- Reach (unique people who saw it)
- CPM (cost per 1,000 impressions)
Engagement Metrics:
- Clicks, CTR (click-through rate)
- Engagement rate (likes, comments, shares)
- Video views, watch time
Conversion Metrics:
- Conversions (sales, leads, sign-ups)
- Conversion rate (conversions ÷ clicks)
- CPA (cost per acquisition)
- ROAS (revenue ÷ ad spend)
Calculating ROAS
ROAS = Revenue from Ads ÷ Ad Spend
Example: R10,000 in sales from R2,500 ad spend = 4x ROAS
- Break-even: ROAS covers your costs (typically 2-3x)
- Profitable: ROAS exceeds costs + desired profit margin
- Target: Most e-commerce aim for 3-5x ROAS
Getting Started
Set Up Tracking
Install Meta Pixel and Google Analytics. Set up conversion events for key actions (purchase, lead, etc.).
Define Your Audience
Create a detailed customer persona. Who are they? Where are they? What do they want?
Choose One Platform
Start with one platform that matches your audience. Don't spread thin.
Create 3-5 Ad Variations
Different headlines, images, or audiences. Let data pick the winner.
Set Small Test Budget
R50-R100/day for 1-2 weeks. Enough data to learn, not enough to waste.
Analyze and Optimize
After 1 week, pause losers, scale winners. Repeat.
