What It Does

Search campaigns show text ads when people search for specific keywords on Google. You select the keywords, write the ads, and set the bids.

Key Characteristics

Keyword-Based Targeting:

• You choose exactly which searches trigger your ads
• Match types (exact, phrase, broad) give targeting flexibility
• Negative keywords prevent irrelevant traffic

High Transparency:

• Full visibility into search terms triggering ads
• Clear performance data by keyword
• Understand exactly where budget goes

Manual Control Options:

• Can use automated bidding OR manual CPC
• Control over ad scheduling, device targeting
• Ability to test specific elements systematically

Intent-Based Advertising:

• Targets people actively searching for solutions
• Higher conversion rates (typically 3-8%)
• Lower funnel, closer to purchase decision

Ideal Use Cases

• High-value B2B lead generation: Where specific keyword targeting is critical
• Local service businesses: Targeting specific service + location searches
• Limited budgets: More efficient with smaller spend
• New accounts: Build conversion data before expanding
• Competitive intelligence: Test which messages resonate

What It Does

Performance Max automatically distributes your ads across all Google channels—Search, Display, YouTube, Gmail, Discover, and Shopping—using AI to optimize targeting and bidding.

Key Characteristics

Full Automation:

• Google controls keyword targeting, audience selection, placements
• AI optimizes based on conversion goals
• Less manual management required

Cross-Channel Reach:

• Single campaign serves ads across entire Google ecosystem
• Reaches users at multiple touchpoints
• Expands beyond search intent to display awareness

Creative-First Targeting:

• Google analyzes engagement patterns to find audiences
• Creative quality directly impacts performance

Limited Transparency:

• Can't see specific search terms or placements
• Aggregated performance reporting
• Difficult to diagnose issues precisely

Ideal Use Cases

• E-commerce with product feeds: Shopping integration is excellent
• Brand awareness + conversions: Multi-channel presence
• Sufficient conversion volume: 30+ conversions/month for optimization
• Strong creative assets: Images, videos, diverse headlines
• Hands-off management preference: Less ongoing optimization needed

Conversion Rates

Search Campaigns:

• Typical conversion rate: 3-8%
• Higher intent = higher conversion likelihood
• Performance more predictable
• Easier to diagnose conversion issues

Performance Max:

• Conversion rates vary widely by channel
• Search portion converts similarly to Search campaigns
• Display/YouTube portions convert lower (0.5-2%)
• Overall campaign CVR depends on channel mix

Winner: Search for consistent conversion rates; PMax for volume at potentially lower efficiency

Cost Efficiency

Search Campaigns:

• CPCs determined by keyword competition
• Can be expensive for competitive keywords
• Control over max CPCs provides budget protection
• Easier to identify and eliminate waste

Performance Max:

• Often achieves lower effective CPCs via cheaper Display/YouTube inventory
• Can be more efficient for broad reach
• Harder to identify wasted spend
• May cannibalize brand searches if not excluded

Winner: Depends on goals—Search for precision, PMax for scale at potentially lower CPCs

Targeting Precision

Search Campaigns:

• Exact match keywords = precise targeting
• Full negative keyword control
• Audience layering options available

Performance Max:

• Audience signals guide (but don't control) targeting
• Limited negative keyword options
• Google decides who sees ads

Winner: Search for precision targeting

Scalability

Search Campaigns:

• Limited by search volume for chosen keywords
• Scaling requires adding keywords or loosening match types
• Eventually hit ceiling based on market size

Performance Max:

• Vast inventory across Google's network
• Scales more easily as budget increases
• Accesses audiences not actively searching

Winner: Performance Max for scale potential

Choose Search If:

• Monthly budget under $2,000

• Need maximum control and transparency
• Don't have strong visual/video assets
• High-value services where precision matters
• Want to understand search behavior before expanding

Choose Performance Max If:

• E-commerce business with product feed
• Monthly budget $3,000+ available
• Generating 30+ conversions/month already
• Have quality images and ideally video content
• Want multi-channel presence
• Willing to accept less control for automation

The Recommended Approach

For most businesses, the optimal strategy combines both campaign types.

Search Campaigns Handle:

• Brand keyword protection
• High-intent non-brand keywords
• Specific product/service targeting
• Geographic-specific campaigns

Performance Max Handles:

• Broad prospecting
• Shopping/product advertising
• Multi-channel brand presence
• Audience expansion

Implementation Structure

Campaign 1: Brand Search

• Exact match brand keywords
• Target impression share bidding
• Protect brand from competitors
• Typically very profitable

Campaign 2: Non-Brand Search

• Targeted exact/phrase match keywords
• Maximize conversions or Target CPA bidding
• Focus on highest-intent searches
• Foundation of lead generation

Campaign 3: Performance Max

• Full asset library uploaded
• Audience signals for guidance
• Brand keywords excluded (negative)
• Scaled prospecting and remarketing

Budget Allocation Guidelines

Strategy	Search	Performance Max
Conservative (New to PMax)	60%	40%
Balanced (Proven PMax)	40%	60%
Aggressive (E-commerce)	20%	80%

The Brand Cannibalization Problem

Issue: Performance Max often spends heavily on brand searches—showing ads to people already searching for your brand who would convert anyway.

Solutions:

• Run separate Brand Search campaign
• Add brand keywords as negatives in PMax (limited options)
• Monitor Insights tab for brand spend percentage
• Evaluate incrementality

The Transparency Gap

Search Advantage: Full search terms report, keyword performance, placement data

PMax Challenge: Can't see specific search terms, limited placement visibility

Workaround Approaches:

• Use Insights tab for directional data
• Monitor by asset group performance
• Analyze conversion source breakdowns
• Compare brand vs. non-brand campaign incrementality

The Creative Dependency

Search: Text-only, easier to create and test

PMax: Requires images, ideally video, multiple text assets

If lacking creative resources:

• Start with Search only
• Invest in creative development
• Add PMax when assets are strong
• Consider creator-first strategy for video content
