    3. Answer The Public (question-based keywords)

    4. Google Search Console (your current rankings)

  • Usually cheapest
  • Highest conversion rate
  • 2. Commercial intent:

  • "buy [product]"
  • "[product] for sale"

    Match Types

    Broad Match

  • Shows for searches related to your keyword
  • Maximum reach
  • Less control
  • Example: Keyword "running shoes"

    May show for: buy sneakers, athletic footwear, jogging shoes

    Phrase Match

  • Shows when search includes your phrase or close variations
  • More control than broad
  • Good balance of reach and relevance
  • Example: Keyword "running shoes"

    May show for: best running shoes, buy running shoes online

    Won't show for: shoe running stores

    Exact Match

  • Shows only for exact keyword or very close variations
  • Most control
  • Lowest reach
  • Most expensive
  • Example: Keyword [running shoes]

    May show for: running shoes, running shoe

    Won't show for: best running shoes

    Match type strategy:

    1. Start with Phrase match

    2. Add Exact for best performers

    3. Use Broad carefully (can waste budget)

    Negative Keywords

    What they are:

    Keywords you DON'T want to show for.

    Examples for "running shoes" store:

    ❌ free

    ❌ cheap

    ❌ DIY

    ❌ repair

    ❌ used

    ❌ jobs

    ❌ how to make

    How to find negatives:

    1. Search terms report (weekly review)

    2. Think about irrelevant searches

    3. Competitor names (unless you want to)

    4. Generic terms

    Add negatives at:

  • Campaign level (apply to all ad groups)
  • Ad group level (specific exclusions)
  • Ad Copy Structure

    Headline 1: Primary keyword + benefit

    Example: "Waterproof Running Shoes - Free Shipping"

    Headline 2: Secondary benefit or offer

    Example: "30-Day Returns | Top Rated 2025"

    Headline 3: Brand or trust signal

    Example: "Trusted by 50,000+ Runners"

    Description 1: Expand on benefits

    Example: "Shop premium running shoes designed for comfort and performance. Advanced cushioning technology."

    Description 2: Call to action

    Example: "Order today and get free shipping. 30-day money-back guarantee."

    Ad copy best practices:

    Include keyword in headline

    Clear call-to-action

    Use numbers and specifics

    Highlight unique selling points

    Match ad to landing page

    Use ad extensions

    Ad Extensions

    Callout extensions:

    Additional text highlighting benefits

    Call extensions:

    Add phone number to ad

    Essential for service businesses

    Location extensions:

    Show business address

    Critical for local businesses

    Price extensions:

    Maximize Clicks:

    Best for: Traffic goals, testing

    Target CPA:

    Set target cost per conversion

    Best for: Accounts with sufficient data

    Bidding recommendations:

  • Start: Manual CPC or Maximize Clicks
  • Scale: Target CPA or Target ROAS (after 30+ conversions)
  • Part 4: Shopping Ads Setup

    Campaign Structure

    Standard Shopping:

    More manual control over bids and product groups

    Smart Shopping (Being Phased Out):

    Automated bidding and placement

    → Migrate to Performance Max

    Recommended structure:

    Campaign: Shopping - All Products

    > Ad Group: All Products

    > Product Groups:

  • - Brand A (higher bid)
  • - Brand B (medium bid)
  • - Everything else (lower bid)
  • Product Group Segmentation

    Segment by:

    1. Product type - Category-based grouping

    2. Brand - Different bids per brand

    3. Condition - New vs. refurbished

    4. Item ID - Individual product control

    5. Custom labels - Your own groupings

    Example for clothing store:

    All Products

  • Shirts
  • - T-Shirts ($1.50 bid)
  • - Dress Shirts ($2.00 bid)
  • Pants
  • - Jeans ($1.75 bid)
  • - Chinos ($1.50 bid)
  • Shoes ($2.50 bid)
  • Bidding Strategy

    Start with:

  • Manual CPC
  • Set bids by product group profitability
  • Bid adjustments based on:

    Profit margin (higher margin = higher bid)

    Competition (popular items need higher bids)

    Conversion rate (winners get more budget)

    Inventory (lower bids when stock is low)

    Scale with:

  • Target ROAS (after 15+ conversions)
  • Set realistic targets (start at 200-300%)
  • Shopping Ads Optimization

    Feed optimization:

    Update prices daily

    Remove out-of-stock items

    Optimize titles (keyword-rich)

    High-quality images

    Competitive pricing

    Campaign optimization:

    Add negative keywords weekly

    Adjust bids based on performance

    Pause low performers

    Increase budget for winners

    Test product segmentation

    Common issues:

    ❌ Feed errors → Check Merchant Center

    ❌ Low impressions → Increase bids or improve titles

    ❌ High clicks, low conversions → Check landing page/price

    Part 5: Performance Max Setup

    When to Use Performance Max

    Good fit:

    30+ conversions per month

    Good product feed data

    Want automation

    Limited time for management

    Not ideal for:

    ❌ New accounts (no data)

    ❌ Need specific control

    ❌ Testing phase

    ❌ Limited budget (<$50/day)

    Asset Groups

    What they are:

    Collections of creative assets (images, videos, headlines, descriptions) for different audience themes.

    Example asset groups for clothing store:

    1. Women's Activewear - Yoga pants, sports bras assets

    2. Men's Casual - T-shirts, jeans assets

    3. Athletic Shoes - Running, training shoe assets

    Assets needed per group:

  • 3-5 headlines (30 chars)
  • 5 long headlines (90 chars)
  • 4 descriptions (60 chars)
  • 1-5 descriptions (90 chars)
  • 1-20 images (landscape, square, portrait)
  • 1-5 videos (optional but recommended)
  • 1-5 logos
  • Audience Signals

    What they are:

    Hints to help Google find your ideal customers faster.

    Types of signals:

    1. Custom segments - Keywords and URLs

    2. Demographics - Age, gender, income

    3. Your data - Website visitors, customer lists

    4. Interests - Affinity and in-market audiences

    How to set:

    1. Create asset group

    2. Add audience signals

    3. Use 2-5 different signal types

    4. Let Google expand beyond signals

    Important: Signals are guides, not restrictions. Google will go beyond your signals.

    Performance Max vs Search/Shopping

    Run Performance Max when:

    You want maximum reach

    You have good conversion data

    You trust automation

    Keep Search/Shopping when:

    You want keyword control

    You have specific testing needs

    PMax alone isn't hitting goals

    Best practice:

    Run both, but exclude Search/Shopping inventory from PMax using campaign settings.

    Part 6: Budget & Bidding Strategy

    Starting Budgets by Campaign Type

    Search Ads:

  • Test: $20-50/day
  • Requires: 2-3x your target CPA minimum
  • Example: $30 target CPA = $60-90/day budget
  • Shopping Ads:

  • Test: $30-75/day
  • Requires: Enough budget for 1-2 sales/day minimum
  • Example: 2% conversion rate, $50 AOV = need 50-100 clicks/day
  • Performance Max:

  • Test: $50-100/day minimum
  • Requires: 3x your target CPA
  • Example: $25 target CPA = $75+/day budget
  • Display Ads:

  • Test: $10-30/day
  • Very low CPC, high volume needed
  • Budget Allocation

    E-commerce recommended split:

  • Shopping: 50%
  • Search: 30%
  • Performance Max: 15%
  • Display/Retargeting: 5%
  • Service business recommended split:

  • Search: 70%
  • Display/Retargeting: 20%
  • Performance Max: 10%
  • Bidding Strategy by Stage

    Testing phase (First 30 days):

  • Manual CPC or Maximize Clicks
  • Gather data
  • Goal: 30+ conversions
  • Growth phase (30-90 days):

  • Target CPA or Target ROAS
  • Set realistic targets
  • Scale budget gradually
  • Mature phase (90+ days):

  • Maximize Conversion Value
  • or Maintain Target ROAS
  • Focus on profit optimization
  • Setting Target CPA/ROAS

    Target CPA calculation:

    1. Know your profit per sale

    2. Determine acceptable CAC

    3. Set target at 70-80% of acceptable CAC

    Example:

  • Product price: $100
  • Product cost: $40
  • Profit: $60
  • Acceptable CAC: $40 (to maintain 20% profit)
  • Target CPA: $32 (80% of $40)
  • Target ROAS calculation:

    ROAS = Revenue ÷ Ad Spend

    Example:

  • Want 3x ROAS
  • Set target ROAS: 300%
  • Starting targets:

  • E-commerce: 200-300% ROAS
  • Lead gen: $50-150 CPA (varies widely)
  • Local services: $30-100 CPA
  • Common Mistakes to Avoid

    ❌ Too low budget

    Need at least 2-3x target CPA daily.

    ❌ Impatient optimization

    Wait 7-14 days before major changes.

    ❌ Ignoring search terms

    Review weekly, add negatives.

    ❌ Bad landing pages

    Fast-loading, mobile-optimized pages required.

    ❌ No conversion tracking

    Can't optimize without data.

    ❌ Only using one campaign type

    Test multiple approaches.

    ❌ Set and forget

    Weekly optimization is essential.

    2. Choose campaign type based on your business

    3. Start with small budget ($50-100/day)

    4. Run for 14 days minimum without changes

    5. Analyze performance and optimize

    6. Scale winners, pause losers

    7. Test new campaigns continuously
