Running Google Ads is an effective way to reach customers, but many businesses make Google Ads mistakes, leading to wasted budgets without results. Dali Agency reveals 6 common mistakes when running Google Ads, how to fix them, and expert tips to optimize campaigns, boost conversions, and save costs.
1. Choosing the wrong keywords
A common Google Ads error is selecting unsuitable keywords. For example, using broad terms like “phone” instead of “affordable high-end phone” wastes money on irrelevant clicks.
How to Fix:
-
Use Google Keyword Planner to find Google Ads keywords with high purchase intent.
-
Use long-tail keywords to target the right audience.
-
Add negative keywords to eliminate unrelated queries.
Tip from Dali Agency: We provide in-depth keyword analysis, ensuring your campaign targets the right customers, saving up to 20% of costs.
2. Ignoring quality score
Quality Score directly impacts cost per click (CPC) and ad placement. Ignoring it is a mistake when running Google Ads, leading to higher costs with lower results.
How to Fix:
-
Ensure landing pages are relevant to Google Ads keywords and ads.
-
Write compelling ad titles with the main keyword.
-
Optimize page load speed by compressing images.
Tip from Dali Agency: Dali Agency offers Quality Score optimization services, from content to technical aspects, reducing CPC and improving ad placement.
3. Not using negative keywords
Failing to use negative keywords causes ads to show for irrelevant searches, wasting budget. This is a common Google Ads mistake many make.
How to Fix:
-
Add negative keywords during campaign setup.
-
Review Search Terms Report to identify unwanted keywords.
-
Regularly update the negative keyword list.
Tip from Dali Agency: We build precise negative keyword lists, ensuring ads reach only potential customers.
4. Ignoring ad extensions

Ad extensions (sitelinks, callouts, phone numbers) make ads stand out, but many businesses overlook them, reducing click-through rates (CTR). This is a regrettable Google Ads mistake.
How to Fix:
-
Add at least 3 extensions: sitelinks, callouts, and contact info.
-
Use strong CTAs like “Order Now!”.
-
Monitor extension performance via Google Ads Dashboard.
Tip from Dali Agency: Dali Agency designs custom ad extensions, boosting CTR by up to 15% and increasing ad visibility.
5. Targeting the wrong audience
Targeting the wrong audience or location is a Google Ads error that wastes budget. For example, advertising nationwide when you only operate in Ho Chi Minh City.
How to Fix:
-
Use Location Targeting to limit ad reach.
-
Analyze data to identify age, gender, and interests.
-
Apply Behavioral Targeting for better precision.
Tip from Dali Agency: We use advanced analytics to target the right customers, increasing conversion rates by up to 25%.
6. Not tracking campaigns
Running Google Ads without tracking is the biggest mistake when running Google Ads. Lack of optimization wastes budget without meeting goals.
How to Fix:
-
Track CTR, CPA, and ROAS via Google Analytics and Google Ads.
-
Optimize weekly, allocating budget to high-performing ad groups.
-
Run A/B tests to find the best ad content.
Tip from Dali Agency: Dali Agency provides transparent reports and continuous optimization, ensuring maximum ROI.
