Google Ads is one of the most powerful advertising platforms available, but it is also one of the easiest to waste money on. We regularly audit accounts that are hemorrhaging budget due to avoidable mistakes. Here are the most common ones and how to fix them.
1. Ignoring Negative Keywords
Without a robust negative keyword list, your ads will show for irrelevant searches that waste clicks. Review your search terms report weekly and add irrelevant queries as negative keywords. This single practice can improve campaign efficiency by 20-30%.
2. Sending Traffic to Your Homepage
Your homepage is not a landing page. Create dedicated landing pages for each ad group that match the ad messaging, include a clear call to action, and remove navigation distractions. Relevant landing pages improve Quality Score, lower costs, and increase conversions.
3. Not Using Conversion Tracking
If you are not tracking conversions, you are flying blind. Set up conversion tracking for all valuable actions — form submissions, phone calls, purchases, and chat initiations. Without this data, you cannot optimize for what actually matters to your business.
4. Set-It-and-Forget-It Bidding
Google Ads requires ongoing optimization. Review performance data regularly, adjust bids based on device, time of day, location, and audience performance. Test smart bidding strategies like Target CPA and Maximize Conversions, but monitor them closely.
5. Too Many Keywords Per Ad Group
Cramming dozens of keywords into a single ad group makes it impossible to write relevant ads. Use tightly themed ad groups with 5-15 closely related keywords, and write ads that directly address the search intent of each group.
6. Not Testing Ad Copy
Running a single ad variation means you are never improving. Always have at least 3 responsive search ad variations per ad group, and regularly test new headlines, descriptions, and calls to action to continuously improve click-through and conversion rates.
