Common Google Ads Mistakes Businesses Make and How to Fix Them

You are probably spending hundreds or maybe thousands on Google Ads every month. But if your clicks aren’t turning into customers, you might be making the same Google Ads mistakes most businesses do. The good news? These mistakes to avoid in Google Ads can be fixed quickly once you know where your money is leaking.

At Fulfillit, we have audited and revived countless ad accounts that were struggling to convert. So in this guide, we will walk you through the most common Google Ads mistakes, how to identify them, and the exact Google Ads process we use to fix them for our clients.

Why Avoiding Google Ads Mistakes Is Crucial

Running ads without a solid strategy is like driving with your headlights off, you are moving fast, but you don’t know where you are headed.

According to Google, advertisers waste nearly 30% of their budget due to poor keyword targeting and tracking errors. That means every third dollar could be going to clicks that never convert.

Whether you’re a small business wondering does Google Ads work for small businesses? or a growing brand trying to scale campaigns, learning to spot and correct these Google Ads campaign mistakes to avoid is key to profitability.

Top 10 Common Google Ads Mistakes to Avoid and How We Fix Them

Below are the top mistakes to avoid in Google Ads, with real examples and Fulfillit’s tested solutions.

1. Targeting the Wrong Keywords

One of the biggest common Google Ads mistakes we see is businesses using broad match keywords that attract irrelevant traffic.

When your ads show for “free marketing tools” while you’re selling premium software, you waste clicks and lower your Quality Score.

Quick Fix:

• Switch to phrase or exact match keywords.
• Use the Search Terms Report weekly.
• Add irrelevant queries to your negative keywords list.
• Segment campaigns by intent—research, commercial, transactional.

Fulfillit Fix: We build data-driven keyword clusters and align them with your conversion funnel, ensuring every click has intent.

2. Ignoring Negative Keywords

Many businesses forget to add negative keywords, which leads to wasted spend. This is one of the top mistakes to avoid in Google Ads because it directly affects your ROI.

Example: If you sell “luxury watches,” your ad might trigger for “cheap watches” unless you exclude “cheap.”

Quick Fix:

• Add negatives regularly based on the Search Terms Report.
• Create shared negative lists for similar campaigns.
• Review competitor brand terms to avoid irrelevant clicks.

Fulfillit Fix: We maintain automated negative keyword lists that update dynamically, saving up to 22% of wasted ad spend per month.

3. Broken or Missing Conversion Tracking

If you don’t track conversions properly, you can’t tell what’s working. That’s one of the most damaging Google Ads campaign mistakes to avoid.

Quick Fix:

• Ensure all key actions (form submissions, calls, purchases) are tracked via GA4 + Google Ads tags.
• Test your conversions using Google Tag Assistant.
• Track micro-conversions (scrolls, time on page) for deeper insight.

Fulfillit Fix: We audit your entire tracking setup and rebuild your Google Ads SOP (Standard Operating Procedure) to ensure data accuracy.

4. Weak Ad Copy and Irrelevant Messaging

Many campaigns fail due to poor copywriting—a common google ads copy mistake that kills click-through rates.

Quick Fix:
Use this 4-part ad copy framework:

1. Hook: Call out pain points.
2. Benefit: Show what’s in it for the user.
3. Proof: Add a number or stat.
4. CTA: Tell them what to do next.

Example:
Bad: “We offer digital marketing.”
Good: “Double your leads in 30 days with proven Google Ads strategies.”

Fulfillit Fix: Our ad copywriters craft emotional yet data-backed messages that align with your landing page intent—no fluff, just conversions.

5. Sending Traffic to Weak Landing Pages

Even the best ad can’t convert on a bad page. Many Google Ad campaign mistakes happen when users are sent to generic homepages instead of conversion-focused landing pages.

Quick Fix:

• Match ad copy to the landing page headline.
• Use one clear CTA (no distractions).
• Improve load speed (under 3 seconds).
• Add trust elements—testimonials, badges, guarantees.

Fulfillit Fix: We design high-converting, ad-specific pages that improve Quality Scores and reduce CPC.

6. Over-Reliance on Smart Bidding Without Data

Google’s automated bidding can be powerful—but not when your account lacks historical data. That’s a common Google Ads manager mistake.

Quick Fix:

• Start with manual CPC until you have at least 30 conversions.
• Transition to Target CPA or Target ROAS gradually.
• Split-test bidding strategies to compare outcomes.

Fulfillit Fix: We balance automation with manual oversight, using hybrid models that adapt to performance in real time.

7. Ignoring Ad Extensions

Skipping ad extensions is another simple yet costly Google Ad mistakes to avoid. Extensions give you more screen space and improve CTR.

Quick Fix:

• Add site links for quick navigation.
• Use callouts for USPs (“24/7 Support,” “Free Trial”).
• Enable structured snippets and call extensions.

Fulfillit Fix: Our campaigns utilize full extension coverage to maximize ad real estate and click-through potential.

8. Neglecting Mobile Optimization

With over 60% of traffic coming from smartphones, ignoring mobile users is among the top mistakes to avoid in Google Ads.

Quick Fix:

• Use responsive search ads.
• Optimize mobile landing pages for speed and usability.
• Monitor device-level performance reports.

Fulfillit Fix: We ensure mobile-first optimization, from copy to page design, driving better conversions for on-the-go users.

9. No Audience Layering or Remarketing

Failing to use remarketing lists is a missed opportunity and a very common google ad campaign mistake.

Quick Fix:

• Segment audiences (visitors, add-to-cart, converters).
• Create custom intent and lookalike audiences.
• Use RLSA (Remarketing Lists for Search Ads).

Fulfillit Fix: Our remarketing flows recover 20–35% of lost conversions using strategic audience layering.

10. Ignoring Policy Compliance

Many businesses unintentionally violate Google’s ad policies, leading to disapprovals or suspensions—classic avoiding common Google Ads policy mistakes.

Quick Fix:

• Review Google’s ad policy center regularly.
• Avoid misleading claims or restricted content.
• Always use official brand names and clear disclaimers.

Fulfillit Fix: We monitor accounts with automated alerts and ensure all creatives remain compliant, saving your account reputation.
