10 Common Mistakes in Google Ad Management and How To Avoid Them

Mistake 1: Inconsistent Conversion Tracking Setup

The Problem: Brad Geddes from Adalysis identifies inconsistent conversion tracking as the top mistake in Google Ad Management for 2025. When conversion actions use different attribution methods, count types, and conversion windows, data becomes skewed across your entire account.

According to Search Engine Land’s December 2024 analysis, “optimization decisions are made from conversion data. If your conversion tracking is inconsistent, then all your data is skewed across your account.” This creates a domino effect where every optimization decision is based on flawed information.

The Solution: Audit your conversion tracking setup quarterly. Ensure all conversion actions use consistent attribution models, count types, and conversion windows. Use Google Tag Manager to implement standardized tracking across all campaigns. Document your tracking setup and share it with team members to maintain consistency.

AI-powered video tools like Luma Dream Machine and Synthesia are now being used by savvy marketers to create conversion-focused landing page videos that improve tracking accuracy by reducing bounce rates and increasing engagement time.

Mistake 2: Neglecting Exact Match Keywords in Google Ad Management

The Data Behind the Problem: Despite Google’s aggressive push toward broad match keywords, exact match consistently remains the highest-converting match type across the majority of advertiser accounts. Adalysis research shows exact match keywords typically achieve 23% higher conversion rates than broad match equivalents.

Many advertisers have abandoned exact match due to interface changes, making broad match the default option, but this decision costs them qualified traffic and conversions.

Strategic Fix: Implement a balanced keyword strategy using 60% exact match, 30% phrase match, and only 10% broad match for new campaigns. Create separate ad groups for high-intent exact match keywords with tailored ad copy and dedicated landing pages.

Pro Tip: Modern AI video creation tools like Pictory and InVideo can help create keyword-specific video ads that perform exceptionally well with exact match campaigns, as they allow precise message matching between search intent and creative content.

Mistake 3: Campaign Settings Inconsistency

Campaign settings inconsistencies plague even experienced PPC managers. When conducting account audits, agencies frequently discover campaigns with mismatched geographic targeting, inconsistent ad scheduling, and varying bid strategies that weren’t intentionally configured.

What the Data Shows: Crownsville Media’s 2025 analysis of therapy practice accounts revealed that 84% of underperforming campaigns had inconsistent settings compared to top performers in the same accounts.

Campaign creation often happens months or years apart, leading to different default settings being applied. This creates performance disparities that make optimization difficult.

Systematic Solution: Create a campaign setup checklist including geographic targeting, ad scheduling, bid strategies, and audience settings. Use Google Ads scripts or third-party tools like Optmyzr to audit campaign settings monthly. Maintain documentation of intentional setting variations and their business justifications.

Mistake 4: Obsessing Over Ad Strength Scores

The Counterintuitive Truth: Google’s ad strength recommendations often conflict with conversion performance. Adalysis research consistently demonstrates that lower ad strength ads achieve higher conversion rates than high ad strength ads.

This happens because higher ad strength gives Google more control over ad messaging, while lower ad strength maintains advertiser control over specific value propositions and calls-to-action.

Important Clarification: Ad strength does not impact Quality Score, despite common misconceptions in the PPC community.

Performance-Focused Approach: Prioritize conversion data over ad strength scores. Test ad variations with specific, controlled messaging against Google’s “excellent” ad strength recommendations. Track conversion rates, not ad strength scores, as your primary creative optimization metric.

AI video platforms like Colossyan and HeyGen enable creation of highly specific, conversion-focused video ads that may receive lower ad strength scores but deliver superior business results.

Mistake 5: Failing to Add High-Volume Search Terms as Keywords

The Missed Opportunity: With match types becoming broader, failing to add top-performing search terms as exact match keywords creates multiple problems for Google Ad Management. The same search term can trigger ads from different ad groups, creating inconsistent messaging and poor user experiences.

Performance Max Impact: When you don’t have exact match keywords for high-volume search terms, Performance Max campaigns often override your search campaigns. Since Performance Max typically achieves lower click-through rates and conversion rates than well-optimized search campaigns, this hurts overall account performance.

Data-Driven Solution: Weekly search term analysis should be standard in your Google Ad Management routine. Add any search term generating 10+ clicks or 2+ conversions as an exact match keyword in the most relevant ad group. This ensures consistent ad messaging and landing page experiences while preventing Performance Max interference.

Mistake 6: Mismatching Broad Match with Wrong Bid Strategies

The Strategy Disconnect: Broad match keywords can be effective, but only with compatible bid strategies. The choice between target-based and max-based bidding dramatically impacts broad match performance.

Research Findings: Google’s bid strategy selection affects broad match performance more significantly than any other keyword match type. Max bidding (maximize conversions or maximize conversion value) focuses on volume regardless of cost efficiency, while target bidding (target CPA or target ROAS) maintains cost control.

Strategic Implementation: Use broad match keywords exclusively with target-based bid strategies (Target CPA, Target ROAS). If using maximize conversion or maximize conversion value bidding, stick to exact and phrase match keywords for better cost control.

When implementing this strategy, video creation tools like Runway ML and AI Studios by DeepBrain can generate multiple ad creative variations to test against different search intents that broad match keywords might capture.

Mistake 7: Using Outdated Negative Keyword Lists Without Auditing

The Hidden Cost: Negative keyword conflicts represent one of the most overlooked issues in Google Ad Management. Many advertisers apply decade-old negative keyword lists without considering how business offerings, market terminology, or search behavior has evolved.

Account Audit Findings: Nearly every professional account audit reveals negative keyword conflicts where valuable keywords are blocked from showing due to outdated negative keyword lists.

These conflicts are particularly tricky because campaigns can still receive impressions, clicks, and conversions when the search term differs from the blocked keyword, making the problem difficult to detect without systematic analysis.

Modern Management Approach: Quarterly negative keyword audits should examine conflicts between positive and negative keywords. Use tools like Optmyzr or Adalysis for automated conflict detection. Before applying negative keyword lists to new campaigns, review each negative keyword’s current relevance to your business.

Mistake 8: Accepting Google Recommendations Without Strategic Analysis

The Platform Bias: Google’s recommendations prioritize platform revenue over advertiser success. While some suggestions provide value, many can decrease account performance if implemented without analysis.

Performance Impact: Search Engine Land’s analysis shows that blindly accepting recommendations often leads to budget increases, broader targeting, and reduced advertiser control – all factors that can harm campaign efficiency.

Critical Evaluation Process: Review each recommendation’s potential impact on your specific business goals. Test controversial recommendations on small budget portions before full implementation. Focus on recommendations that improve ad relevance and user experience rather than those that primarily increase spend.

AI Integration Note: Modern AI video tools like Peech and Vyond are now being used to create recommendation-specific test creatives, allowing advertisers to properly evaluate Google’s suggestions with appropriate creative assets.

Mistake 9: Enabling Auto-Apply Recommendations

The Automation Risk: Auto-apply settings allow Google to make account changes without advertiser approval, including adding keywords, changing match types, and modifying bid strategies.

Real-World Impact: PPC professionals report instances where auto-apply settings have “wrecked accounts” by implementing multiple changes simultaneously without strategic oversight.

Control-Focused Setup: Disable all auto-apply settings in your Google Ad Management workflow. Instead, review recommendations manually to make informed decisions. This maintains strategic control while still benefiting from Google’s suggestions when appropriate.

Mistake 10: Over-Relying on AI Without Strategic Oversight

The Balance Challenge: While AI capabilities in Google Ad Management continue expanding rapidly, successful campaigns still require human strategic oversight, creativity, and business understanding.

Expert Perspective: As Brad Geddes notes, “AI is like a child who wants to please others. It will give you an answer, even if it’s wrong.” AI excels at pattern recognition and mathematical optimization but lacks contextual business understanding, empathy, and the ability to handle exceptional situations.

Human-AI Partnership: Use AI for data analysis, pattern detection, and routine optimizations while maintaining human oversight for strategic decisions, creative direction, and business context interpretation. Your industry knowledge and business understanding remain irreplaceable assets in effective Google Ad Management.

Future-Forward Integration: Leading advertisers are now combining AI-powered video creation tools like revid.ai and Luma Dream Machine with human strategic oversight to create highly effective, data-driven creative assets while maintaining brand consistency and business relevance.

Implementing These Google Ad Management Best Practices

Start with Foundation: Begin by auditing your conversion tracking setup and campaign settings consistency. These foundational elements impact every other optimization effort.

Progressive Implementation: Address 2-3 mistakes per month rather than attempting to fix everything simultaneously. This allows for proper testing and performance measurement.

Continuous Monitoring: Modern Google Ad Management requires ongoing attention to algorithm updates, market changes, and performance trends. Set up automated alerts for significant performance changes and schedule monthly account reviews.

AI-Enhanced Optimization: Leverage AI tools for creative production and data analysis while maintaining human strategic control. Tools like Clipchamp’s AI and Buffer’s AI video tools can enhance your creative capabilities without replacing strategic thinking.

Conclusion

Effective Google Ad Management in 2025 requires balancing automation capabilities with strategic human oversight. By avoiding these ten common mistakes, businesses can significantly improve campaign performance, reduce wasted ad spend, and achieve better return on investment.
