Common Mistakes Newbies Make in Google Ads (And How to Avoid Them)

Google Ads is one of the most powerful online advertising platforms available today. It allows businesses to reach highly targeted audiences, generate leads, and increase sales with measurable results. However, many beginners struggle to see a positive return on investment because they unknowingly make mistakes that drain their budget and weaken campaign performance. Understanding these common pitfalls can help new advertisers avoid costly errors and create more effective campaigns.

Not Defining Clear Goals Before Launching

One of the biggest mistakes new advertisers make in Google Ads is running campaigns without clear objectives. Jumping into advertising without knowing whether the goal is brand awareness, lead generation, or direct sales often results in wasted money. For example, a local business might aim for store visits, while an e-commerce store may want more online purchases. By not defining success upfront, it becomes difficult to measure performance or optimize effectively. The best way to avoid this mistake is to set specific and measurable goals such as “increase website conversions by 20% in three months” or “get 50 new leads per month.”

Targeting Too Broadly

Many beginners believe that reaching a wide audience will bring more customers, but in reality, targeting too broadly often means paying for irrelevant clicks. For example, a small bakery in Singapore might accidentally target people worldwide instead of focusing on its local area. This not only wastes ad spend but also reduces campaign relevance. The solution is to narrow targeting by using location filters, audience segmentation, and negative keywords to refine who sees your ads. Starting small and scaling gradually is usually more cost-effective.

Ignoring Negative Keywords

New advertisers often overlook the importance of negative keywords, which help filter out irrelevant search terms. For example, if you are selling premium watches, you don’t want your ad appearing for searches like “free watches” or “cheap watches.” Without negative keywords, your ads will attract unqualified clicks, increasing costs without conversions. Regularly reviewing the search terms report and adding negative keywords ensures your budget is spent only on searches that are relevant to your business.

Writing Weak Ad Copy

A common issue in Google Ads campaigns is poorly written ad copy that fails to grab attention or encourage clicks. Beginners sometimes stuff keywords unnaturally or write vague descriptions that don’t highlight benefits. Strong ad copy should be clear, persuasive, and aligned with the searcher’s intent. Using action-oriented language, emphasizing unique selling points, and including a call-to-action can significantly improve click-through rates. Testing multiple variations of ad copy is also essential to see which messaging resonates best with your audience.

Not Using Ad Extensions

Another mistake is neglecting ad extensions, which enhance the visibility and performance of Google Ads. Extensions such as sitelinks, call extensions, and location extensions provide additional information and encourage engagement. For instance, a business can include direct links to specific product categories or highlight promotions in their ad. Ads with extensions tend to achieve higher click-through rates and improve overall quality score. To avoid this mistake, always make use of the relevant extensions available for your campaign type.

Poor Keyword Research

Many beginners assume that bidding on high-volume keywords guarantees results, but this often leads to overspending and irrelevant traffic. For example, bidding on a broad keyword like “shoes” will attract clicks from people searching for many different types of shoes, not necessarily the kind you sell. Proper keyword research involves finding a balance between search volume, competition, and relevance. Tools like Google Keyword Planner can help identify long-tail keywords that are less competitive but more targeted. This approach often results in higher-quality traffic at a lower cost.

Failing to Track Conversions

A major mistake in Google Ads is running campaigns without proper conversion tracking. Without tracking, advertisers cannot measure which keywords, ads, or campaigns are driving actual sales or leads. Many beginners focus only on clicks and impressions, which don’t always reflect business outcomes. Setting up conversion tracking through Google Ads or Google Analytics allows advertisers to understand ROI and optimize campaigns effectively. This data-driven approach ensures ad spend is directed towards strategies that generate real results.

Not Testing and Optimizing

Google Ads success doesn’t happen overnight, yet many new advertisers launch campaigns and leave them running without adjustments. Failing to test ad variations, keywords, or bidding strategies prevents campaigns from improving over time. For example, if one ad headline consistently outperforms another, that insight should guide future copy decisions. Similarly, experimenting with different match types, ad formats, and audience settings can uncover new opportunities. The best way to avoid stagnation is to treat Google Ads as an ongoing process of testing, learning, and optimizing.

Overlooking Quality Score

New advertisers often ignore quality score, a key metric in Google Ads that affects both ad ranking and cost-per-click. Quality score is influenced by factors like ad relevance, expected click-through rate, and landing page experience. A low score means you’ll pay more for clicks and your ads may show less frequently. To improve quality score, focus on tightly aligned ad groups, writing relevant ad copy, and ensuring landing pages deliver a good user experience. Higher quality scores not only reduce costs but also increase the chances of better ad placement.

Sending Traffic to the Wrong Landing Page

Another common mistake is directing ad clicks to the homepage instead of a targeted landing page. For example, if an ad promotes a specific product, sending users to the homepage forces them to search for it, increasing the likelihood they’ll leave without converting. A well-optimized landing page should match the ad message, provide relevant details, and make it easy for visitors to take action. Optimized landing pages with clear headlines, strong calls-to-action, and fast load times significantly improve conversion rates.

Overspending Without Budget Control

Beginners sometimes get carried away and spend too much on campaigns without setting clear budget limits. Without daily or monthly caps, costs can escalate quickly, especially if targeting broad keywords. Google Ads provides budget control features that allow advertisers to set spending limits and adjust based on performance. Reviewing campaign spending regularly helps ensure money is being invested wisely. Starting with a modest budget and scaling up as results improve is a safer strategy than overspending from the start.

Ignoring Mobile Users

In today’s digital world, a large portion of Google Ads traffic comes from mobile devices. New advertisers sometimes forget to optimize ads and landing pages for mobile users. This can result in a poor user experience and low conversion rates. Ads should be designed with mobile-friendly formats, and landing pages must load quickly and display properly on smaller screens. Paying attention to mobile performance metrics is crucial to capturing this growing segment of online traffic.

Conclusion

Google Ads is a powerful platform, but beginners often make mistakes that reduce effectiveness and waste budget. Common errors include unclear goals, poor targeting, weak ad copy, and ignoring essential features like negative keywords and ad extensions. Other mistakes such as neglecting conversion tracking, sending traffic to irrelevant landing pages, or failing to optimize for mobile can further hurt campaign performance. By understanding these pitfalls and taking proactive steps to avoid them, new advertisers can maximize their return on investment and build more successful advertising campaigns.
