You’ve set up your PPC campaign, your ads are live, and money is leaving your account. But are you actually getting results? For many beginners, PPC dashboards can feel overwhelming. Numbers everywhere, metrics you’ve never heard of, and no clear sense of what’s good and what’s a red flag.
This guide cuts through the noise. We’ll guide you through the key metrics to watch, how to spot a campaign that’s quietly draining your budget, and the practical steps you can take to turn things around.
The good news: you don’t need to be a data expert to analyse your PPC performance. You just need to know what to look for.
Start With the Metrics That Actually Matter
Before you can fix anything, you need to understand what you’re looking at. PPC platforms such as Google Ads and Bing Ads show you dozens of metrics, but as a beginner, focus on these four first.
Click-Through Rate (CTR)
CTR tells you the percentage of people who saw your ad and clicked on it. If 1,000 people saw your ad and 20 clicked, your CTR is 2%. A low CTR usually means your ad copy isn’t compelling enough, or you’re targeting the wrong audience. As a rough benchmark, a CTR below 1% on a search campaign warrants investigation.
Cost Per Click (CPC)
This is how much you’re paying every time someone clicks your ad. A high CPC isn’t always a problem, but it needs to be balanced against what that click is actually worth to your business. If you’re paying £5 per click but converting one in every five visitors into a £500 sale, that’s a great result. Context is everything.
Conversion Rate
Your conversion rate tells you what percentage of clicks are turning into the action you want, whether that’s a form submission, a phone call, or a purchase. If people are clicking but not converting, the problem is often your landing page, not your ad.
Cost Per Conversion (CPA)
This is arguably the most important metric for beginners to understand. It tells you exactly how much you’re spending to generate one lead or sale. If your CPA exceeds the value of a conversion, your campaign is losing money. Simple as that.
How to Spot an Underperforming Campaign
Knowing your metrics is one thing. Knowing when they’re telling you something is wrong is another. Here are the most common warning signs to look out for.
You’re getting clicks but no conversions
This is one of the most frustrating situations in PPC. Your ads are working, people are interested enough to click, but nothing is happening after that. The culprit is almost always the landing page. Ask yourself:
- Does the landing page match what the ad promised?
- Is the page loading quickly on mobile?
- Is there a clear, obvious call to action?
- Are you asking for too much information on a contact form?
A disconnect between your ad and your landing page is the single biggest cause of poor conversion rates for beginners.
Your budget is being spent on irrelevant searches
If you’re running search ads, they appear when people type specific keywords into Google. But without proper negative keyword management, your ads can show up for searches that have nothing to do with your business.
For example, if you sell premium office furniture and you’re bidding on the keyword “office chairs”, your ad might appear for searches like “office chair repairs” or “second-hand office chairs”. Those clicks cost you money but are unlikely to convert.
Check your Search Terms report regularly. It shows you the actual searches that triggered your ads, and you’ll often find surprising (and expensive) irrelevant matches hiding in there.
Your Quality Score is low.
Google assigns each of your keywords a Quality Score from 1 to 10. It’s based on how relevant your ad and landing page are to the keyword you’re bidding on. A low Quality Score means you’re paying more per click than you should be, and your ads may appear less frequently.
A Quality Score of 7 or above is a healthy target.
If yours is sitting at 3 or 4, it’s a signal that your keywords, ad copy, and landing page aren’t aligned well enough.
Five Practical Fixes to Improve Performance
Once you’ve identified where things are going wrong, here’s where to start with improvements.
1. Tighten your keyword match types
Broad match keywords give Google a lot of freedom to show your ads for loosely related searches. Switching to phrase match or exact match gives you more control over when your ads appear and often substantially reduces wasted spend.
2. Build out your negative keyword list
After reviewing your Search Terms report, add any irrelevant searches as negative keywords. This stops your budget from being wasted on clicks that will never convert. It’s one of the quickest wins available to any PPC campaign.
3. Rewrite underperforming ad copy
If your CTR is low, your ad isn’t grabbing attention. Try leading with a benefit rather than a feature. Instead of “We offer 24-hour plumbing services”, try “Blocked drain? We’re there in 60 minutes.” Speak directly to the problem your customer is trying to solve.
4. Improve your landing page alignment
Every ad should link to a page that directly corresponds to its message. If your ad promotes a specific product or service, don’t send people to your homepage. Create a dedicated landing page that keeps the conversation your ad started going.
5. Review your bidding strategy
If you’re new to PPC, you may have been guided towards an automated bidding strategy like Maximise Clicks. This can be useful early on, but once you have conversion data, switching to Target CPA or Maximise Conversions often delivers much better results. Let Google optimise for what actually matters to your business.
How Often Should You Be Reviewing Performance?
This is a question we hear a lot from businesses who are new to PPC. The honest answer is: more often than you think, especially in the early weeks.
When a campaign is new, it needs close attention. Check in every two to three days to review your Search Terms report, monitor your spend, and look for any obvious issues. Once a campaign has been running for a few weeks and you’ve made your initial optimisations, a weekly review is usually sufficient.
What you’re looking for in each review:
- Any significant changes in CTR or conversion rate
- New irrelevant search terms to add as negatives
- Keywords that are spending heavily without converting
- Ads that are consistently outperforming others (and why)
The biggest mistake beginners make is setting up a campaign and leaving it alone. PPC is not a set-and-forget channel. Regular, consistent review is what separates campaigns that quietly drain budgets from those that deliver a genuine return.
