If you’ve ever set up a Google Ads campaign and felt unsure what you were doing, you’re not alone.
Many first-time advertisers rush through the setup process. But skipping steps or misunderstanding how campaigns work can lead to costly errors. Poor structure, weak ad copy, or the wrong settings can burn through your budget with little to show for it.
In this guide, we’ll walk through the most common Google Ads beginner mistakes. You’ll learn how to set up campaigns that actually perform, avoid ppc mistakes that drain your ad spend, and use your data to improve results over time.
By the end, you’ll have a clear plan to fix what’s not working and build better ads that convert. Ready? Let’s get started.
Choosing the Wrong Campaign Type
Choosing the right campaign type matters more than people realise. If you pick one that doesn’t match your goals, your ads won’t do what you need them to do. Here’s how each one works—and where new advertisers often go wrong.

Search Campaigns: When You Need Results Fast
Search campaigns show your ads to people who are already looking for what you sell. It’s a good starting point if you want calls, bookings, or sign-ups. Still, many beginners skip it. They often try broader options too soon and miss people who are ready to take action.
Display Campaigns: Great for Brand Awareness
Display ads appear on websites, apps, and YouTube. They get seen a lot, but they don’t always bring in leads. If your goal is sales, not just exposure, this might not be the best option. New advertisers often confuse attention with action.
Smart Campaigns: Easy, but Risky
Smart campaigns let Google decide where and when to show your ads. It’s a quick setup, but you lose control over things like budget and targeting. These campaigns can work, but only if you know what’s happening behind the scenes.
Video Campaigns: Best for Broad Reach, Not Clicks
Video campaigns can help people remember your brand, especially on YouTube. But they need strong videos and a clear message. Without those, it’s easy to spend money without seeing results. This is one of the most common ppc mistakes when people rush in without a plan.
Poorly Structured Ad Groups
Many advertisers dive into Google Ads by creating one or two ad groups, stuffing in a long list of keywords, and calling it a day. But this makes it hard for your ads to match the right searches. It’s one of the most common ppc mistakes: easy to make, easy to fix.
- Too many keywords in one ad group: When every keyword goes into one ad group, the ads become too general. This lowers click-through rates because the message doesn’t line up with what the person searched for. Google rewards relevance, and this setup works against you.
- Mixing unrelated topics: If you combine window tinting and paint protection in one group, your ads won’t speak clearly to either audience. Use different ad groups to separate services, products, or even customer needs. That way, each ad feels more targeted.
- Using the same ad for every keyword: Each keyword deserves an ad that feels like a match. Running the same ad across different ad formats and topics makes your message too broad. Instead, write ads that reflect the intent behind each keyword group.
The structure of your campaigns determines how people experience your ads. Taking the time to set up clear, focused ad groups can help you avoid the same mistakes that trip up most new advertisers.
Skipping Over Campaign Settings
Most beginners fly through campaign settings without knowing what half the options mean. That’s where things start to go wrong. Google gives you flexibility, but if you don’t use it well, you’ll end up with wasted ad spend and poor campaign results.

Take network targeting, for example. Many campaigns are set to show on both the Search Network and Display Network by default. This often puts your ad in front of people who aren’t actively searching. The same goes for audience signals. Without clear signals, Google doesn’t know who to focus on.
Your daily budget is another place where money disappears fast. Set it too high without good targeting, and the clicks won’t be worth it. Set it too low and your ads won’t show often enough. The trick is balance, and that takes testing.
Also, make sure conversion tracking is switched on and connected to Google Analytics. Without it, you’re guessing what works. Settings like ad delivery, schedule, and location targeting matter more than they seem.
To put the value of advertising into perspective, the Australian Government spent $179.3 million on advertising campaigns in 2022–23. That shows how much weight proper planning carries.
Writing Weak Ad Copy
Writing ad copy might seem easy until you realise your ads aren’t getting clicks. One of the most common issues is focusing too much on features and not enough on outcomes. Saying “Open 24/7” is fine. But “Get your plumbing fixed any time, day or night” speaks to what potential customers actually care about.
A lot of ad creation skips over what makes a business different. That’s a missed chance to show your unique selling points. Your target audience wants to know why they should choose you, not someone else. If your message doesn’t answer that clearly, they move on.
Many ads also leave out a clear next step. A line like “We offer landscaping services” doesn’t push action. “Book your free quote online” is much more effective.
Good ad copy makes things easy to understand. Great ad copy makes someone want to take action. Make sure every word is working for you, not just filling space. With a few changes, even your most basic ads can become compelling ad copy that speaks directly to your audience.
Forgetting Ad Extensions
Ad extensions give you more space to promote your business without increasing your budget. Still, a lot of new advertisers skip them during setup. That means your ads might be missing important info that helps people choose you.
Here’s what ad extensions can add:
- Extra details that build trust: Add your phone number, business hours, or extra links to popular pages.
- More space on the results page: Larger ads stand out and push other listings further down.
- Room to show what makes you different: Callouts let you highlight your unique selling points, like fast turnaround or no call-out fees.
If you’re running Google Ads, extensions are worth setting up. They help your ads look more complete and can lead to better results. You don’t need to change the whole ad, just add a few helpful details.
Leaving Ad Delivery on Auto-Pilot
Leaving ad delivery on the default settings might seem fine at first. But if you don’t check what’s happening, your ads could show at the wrong times, on the wrong devices, or run out of budget too early in the day.

Most beginners don’t think much about delivery settings, but they shape how and when your ads appear. If your audience is mostly active in the evenings, running ads all day might not work. If mobile traffic performs better, targeting desktop equally could waste clicks.
To make things work better, review your bid strategies and delivery data regularly. Check which times of day get the most conversions. Adjust bids based on that. If mornings perform well, increase your bids there. If nights don’t convert, scale them down.
You don’t need to overhaul everything. But when you regularly review campaign performance, you’ll start to notice patterns. From there, you can optimise bids and make sure your budget is spent where it counts most.
Not Testing Your Ads
One of the fastest ways to improve your results in Google Ads is to test what you’re showing. But most advertisers skip this step. They set up one ad, let it run, and assume it will work. That leaves a lot of performance on the table.
Good ad testing is about trying different ad variations, one change at a time. For example, test one new headline while keeping the rest the same. Then, swap in a new call-to-action next round. This helps you see what actually makes a difference.
Make testing a normal part of how you run your campaigns. Even small updates, like using a stronger verb or shortening a sentence, can help the ad feel clearer. And clearer ads usually get more clicks.
The trick is to regularly test without overthinking it. Set a reminder to review your ads every few weeks. Look at which versions are performing better and keep the winners. Testing is how you learn what your audience responds to.
With every round of testing, your ads get closer to what people want to see. That’s how good campaigns are built: one small improvement at a time.
Bad Bidding and Broad Match Trouble
Many advertisers set up Google Ads without adjusting how their bids work or how their keywords are matched. This often leads to low-quality traffic, rising costs, and disappointing results.
Broad match is usually where things go wrong. It casts a wide net, showing your ads for searches that might only be loosely related to your offer. That often brings irrelevant clicks that waste your budget.
To tighten things up, focus on these five areas:
- Use exact match for better control: This setting means your ad only appears when someone types your chosen phrase exactly. It helps bring in people who are more likely to convert.
- Add negative keywords to block the wrong traffic: If your ads are showing up for terms like “cheap” or “free,” and you’re not offering those things, you’re wasting clicks. Negative keywords help filter that out.
- Try a mix of match types: Different match types attract different kinds of traffic. Split them into separate ad groups and check which ones bring the right people in.
- Review your bidding method: If your cost per click keeps climbing, switch to manual bidding. This gives you more say over what you’re paying.
- Adjust bids based on real results: Use performance data to increase bids for high-converting keywords and reduce spend on poor performers.
Bid management is insisted in keeping your ppc strategy flexible. Try new keywords, test one change at a time, and optimise bids using what you learn.
Not Checking Campaign Results
Some advertisers launch campaigns and then leave them running without checking back in. That’s where a lot of ad spend disappears. If you don’t regularly review your performance data, you’ll miss out on what’s working and what’s quietly wasting your budget.
Start by checking your click-through rate. If people aren’t clicking, your ads might need stronger wording. Next, look at your conversion rates. If clicks aren’t turning into actions, the landing page might not match what the ad promised.

Use Google Analytics and conversion tracking to see what happens after the click. This shows which campaigns are leading to results and which ones aren’t.
Campaign performance also affects your quality score. That score helps decide how much you pay per click. The better your ads perform, the more efficient your spend becomes. This is how you build better ppc roi without raising your budget.
Online ad spend in Australia reached $512.5 million in early 2010, up 17% in just one year.
Advertisers don’t grow like that by guessing. They track results, fix underperforming campaigns, and stay on top of what the numbers are saying.
