7 Mistakes Businesses Make With Google Ads (And How to Fix Them)

Google Ads is one of the most powerful advertising platforms out there. With over 8.5 billion searches happening on Google every single day, it offers businesses a golden opportunity to put their brand in front of the right audience at the right time.

But here's the catch…

While many businesses jump into Google Ads hoping for quick results, most end up wasting their budget due to critical missteps. Without proper strategy and execution, what was supposed to drive leads and conversions often ends up becoming a costly lesson.

In this blog, we'll uncover the 7 most common Google Ads mistakes businesses make—and more importantly—how to fix them to maximize your ROI and grow smarter.

Google Ads Mistakes

Mistake 1: Poor Keyword Targeting

One of the biggest and most common Google Ads mistakes is targeting the wrong keywords—either too broad or too irrelevant.

Many advertisers assume that broader terms will bring more traffic, but in reality, they bring unqualified clicks. For example, if you sell luxury watches and target “watches,” you'll likely attract bargain hunters who will never convert.

How to Fix It:
✅ Conduct thorough keyword research using tools like Google Keyword Planner, SEMrush, or Ubersuggest.
✅ Focus on long-tail keywords with higher intent (e.g., “buy luxury watches online” instead of just “watches”).
✅ Use keyword match types (Broad Match Modifier, Phrase Match, and Exact Match) smartly.
✅ Regularly review and update your negative keywords list to filter out irrelevant search queries.

By narrowing your targeting and filtering out noise, you'll reach people who are more likely to convert.

Mistake 2: Ignoring Negative Keywords

Negative keywords are the unsung heroes of a profitable Google Ads campaign. Yet, most businesses don't use them effectively—or at all.

Without negative keywords, your ads may show up for completely unrelated or low-intent searches, draining your budget quickly.

How to Fix It:
✅ Use the Search Terms Report in Google Ads to identify irrelevant queries.
✅ Add negative keywords like “free,” “cheap,” or “DIY” (if those don't align with your business).
✅ Continuously build and update your negative keyword list based on performance.

A strategic negative keyword strategy saves money and improves conversion rates by keeping out unqualified traffic.

Mistake 3: Sending Traffic to a Poor Landing Page

Sending users to your homepage—or worse, an irrelevant product page—is a surefire way to lose leads.

Even if your ad is compelling, a bad landing page kills the momentum. If the page is too slow, confusing, or lacking a strong CTA, visitors will bounce.

How to Fix It:
✅ Create dedicated landing pages for each ad group or campaign.
✅ Keep your messaging consistent with the ad copy (message match).
✅ Include clear CTAs (Call to Actions), fast loading times, mobile responsiveness, and trust elements (reviews, badges).
✅ Use tools like Unbounce, Instapage, or Elementor to build high-converting pages.

Great ads are only half the battle—great landing pages seal the deal.

Mistake 4: Not Tracking Conversions Properly

What good is a campaign if you don't know what's working? Too many businesses launch Google Ads without setting up conversion tracking or understanding which actions matter.

This mistake leads to misguided decisions, wasted spend, and missed growth opportunities.

How to Fix It:
✅ Use Google Tag Manager and Google Analytics to track key actions: form submissions, purchases, phone calls, etc.
✅ Set up conversion goals and values in your Google Ads account.
✅ Track micro-conversions (newsletter signups, time on page) to understand early buying intent.
✅ Use UTM parameters to accurately track traffic sources.

With proper conversion tracking, you'll make data-driven optimizations that directly impact your bottom line.

Mistake 5: Ignoring Ad Extensions

Ad extensions are free real estate, yet many businesses ignore them completely. They offer more information, increase CTR (click-through rate), and boost Quality Score.

Skipping ad extensions is like buying a billboard but leaving half of it blank.

How to Fix It:
✅ Add multiple sitelink extensions (e.g., pricing, testimonials, features).
✅ Use callout extensions to highlight USPs (Free Shipping, 24/7 Support).
✅ Include call extensions for instant lead generation.
✅ Utilize structured snippets to showcase services or product categories.

Ad extensions help your ad stand out, gain trust, and improve performance at no extra cost.

Mistake 6: Running Ads Without Split Testing

Creating one ad and hoping it performs well is not a strategy—it's a gamble. Without A/B testing, you'll never know what's working and what's not.

Most businesses run the same ad for months without testing different headlines, descriptions, or CTAs.

How to Fix It:
✅ Create at least 2-3 ad variations per ad group.
✅ Test different headlines, value propositions, and call-to-actions.
✅ Use Responsive Search Ads to let Google test combinations automatically.
✅ Monitor performance and pause underperforming ads regularly.

Split testing helps you maximize ad effectiveness and squeeze more ROI from your spend.

Mistake 7: Not Optimizing Campaigns Regularly

Google Ads is not a “set-it-and-forget-it” platform. Failing to monitor and optimize your campaigns regularly leads to declining performance.

Many businesses launch ads and never check them again—burning money in the background.

How to Fix It:
✅ Perform weekly optimizations—review keywords, bids, ads, and audiences.
✅ Adjust budget based on what's converting.
✅ Pause non-performing ads and scale high-performing ones.
✅ Keep an eye on Impression Share, CPC, CTR, and Quality Score.

Regular optimization ensures your budget is being spent on what drives real results—not just clicks.

Bonus Tips to Supercharge Your Google Ads ROI

🔹 Keep Mobile First: Ensure your ads and landing pages are fully mobile-optimized.
🔹 Use Competitor Campaigns: Bid on brand competitors (carefully) with a strong USP-focused ad.
