Top Mistakes to Avoid When Setting Up Google Ads Campaigns

Google Ads is a powerful platform that allows businesses to reach potential customers with precision, generate leads, and increase conversions. However, launching a campaign without a clear strategy can result in wasted budget, poor performance, and disappointing outcomes.

Here are the top mistakes to watch out for when setting up a Google Ads campaign.

1. Skipping Keyword Research

One of the most critical steps in setting up a successful campaign is comprehensive keyword research. Choosing keywords without analyzing search volume, intent, and competition can result in low-quality traffic or no traffic at all.

Avoid this by:

• Using Google’s Keyword Planner
• Focusing on long-tail keywords for better targeting
• Prioritizing keywords with high intent relevant to your offering

2. Not Using Negative Keywords

Failing to include negative keywords can cause your ads to appear for irrelevant search queries, leading to wasted clicks and a lower return on investment.

Avoid this by:

• Regularly reviewing your search terms report
• Adding irrelevant terms as negative keywords
• Continuously updating your negative keyword list as your campaign evolves

3. Poor Campaign Structure

A disorganized campaign structure makes it difficult to track performance, optimize ads, and control budget allocation. Many advertisers lump all keywords into one ad group or campaign, which decreases relevance and quality score.

Avoid this by:

• Creating separate campaigns for distinct goals
• Grouping similar keywords into tightly themed ad groups
• Writing unique ad copy for each ad group

4. Ignoring Ad Extensions

Ad extensions provide additional information and give your ads more visibility, which can improve click-through rates and ad rank. Ignoring them is a missed opportunity to enhance performance.

Avoid this by:

• Using all relevant extensions (site links, callouts, structured snippets, call extensions, etc.)
• Aligning extensions with your business goals (promotions, contact info, location)

5. Using Broad Match Keywords Without Control

While broad match keywords can increase reach, they often attract unqualified traffic. Without proper monitoring, this can drain your budget quickly.

Avoid this by:

• Starting with phrase or exact match types
• Gradually testing broad match with a solid list of negative keywords
• Monitoring keyword performance closely

6. Weak Ad Copy

Your ad copy is what convinces users to click. Generic, unclear, or uninspiring ads won’t stand out, especially in competitive industries.

Avoid this by:

• Including the main keyword in the headline
• Clearly stating your unique value proposition
• Adding a strong call-to-action (CTA)

7. Not Setting Up Conversion Tracking

Without conversion tracking, it’s impossible to know what’s working. Many businesses run campaigns without measuring form submissions, purchases, or other key actions.

Avoid this by:

• Installing Google Ads conversion tracking
• Integrating with Google Analytics
• Setting up goals for each campaign type

8. Relying on Only One Ad Variation

Running a single ad variation in each ad group limits testing opportunities and reduces your ability to improve over time.

Avoid this by:

• Creating multiple ad versions with different headlines and descriptions
• Testing different CTAs and offers
• Analyzing performance data to refine messaging

9. Setting and Forgetting

Google Ads campaigns require ongoing optimization. Setting a campaign and leaving it alone can lead to performance decline and wasted budget.

Avoid this by:

• Reviewing campaign performance weekly
• Adjusting bids, budgets, and keywords based on results
• A/B testing landing pages and ad copy

10. Not Optimizing for Mobile

With a significant share of traffic coming from mobile devices, your ads and landing pages must be mobile-friendly.

Avoid this by:

• Using responsive ad formats
• Ensuring fast-loading, mobile-optimized landing pages
• Adjusting bids based on device performance
