If you've been running Google Ads for more than a year or two, you've almost certainly noticed it: your cost per click is going up. Not dramatically overnight, but a steady, persistent creep that means the same budget buys fewer clicks than it used to.
You're not imagining it. And you're not alone.
CPCs across almost every industry have been rising consistently for several years. For some sectors, the increases have been dramatic. What cost £2 a click three years ago might cost £3.50 today. The same campaigns, the same keywords, the same ads — just more expensive.
So what's going on, and what can you actually do about it?
What's Driving the Increases
More Advertisers, Same Inventory
The Google Ads platform has grown enormously. More businesses are advertising online than ever before, especially since the pandemic accelerated the shift to digital. But the number of available ad slots on a search results page hasn't changed — there are still only a handful of positions. More competition for the same inventory means higher prices. It's basic supply and demand.
Google's Revenue Targets
Google is a publicly traded company with shareholders expecting growth. Advertising revenue is their primary business. Over time, the platform has evolved in ways that tend to increase advertiser spend: reducing organic visibility to make ads more necessary, introducing more ad formats that take up more of the page, and tweaking auction dynamics. None of this is conspiratorial — it's simply how the business model works.
Automation That Optimises for Google's Benefit
Google has pushed hard toward automated bidding strategies like Maximise Clicks, Maximise Conversions, and Target CPA. These are convenient, but they hand control of your bids to Google's algorithm. In practice, automated bidding frequently pushes CPCs higher than manual bidding would, particularly for businesses with limited conversion data.
The algorithm optimises within the rules it's given, and those rules don't include "spend as little as possible." They include "get results within the parameters set" — and the algorithm is happy to pay more per click if it calculates that doing so meets the target.
Click Fraud
This is the one most advertisers don't think about, but it's a significant factor. When fraudulent clicks consume part of your budget, Google's reporting shows more clicks but the same (or fewer) conversions. Many advertisers respond by increasing bids or budgets to compensate for what looks like declining performance. This creates a cycle: fraud eats budget → performance drops → you spend more → fraud eats more budget.
Across the industry, click fraud is estimated to affect 14-36% of all PPC clicks. If even 20% of your clicks are fraudulent, your effective CPC — the cost per genuine click — is 25% higher than what Google reports.
Keyword Competition Intelligence
Your competitors have access to the same tools you do. Auction insights, third-party competitive intelligence platforms, and agencies all mean that if you find a profitable keyword, your competitors will find it too. Popular keywords become more competitive faster than they used to, and CPCs rise accordingly.
What You Can Actually Do About It
Rising CPCs aren't entirely within your control, but there's plenty you can do to fight back.
1. Audit Your Search Terms Relentlessly
The search terms report shows you the actual queries that triggered your ads. Most accounts have significant wasted spend hiding in irrelevant search terms. Review this weekly, not monthly. Add negative keywords aggressively. A well-maintained negative keyword list can reduce wasted spend by 15-25%.
Don't just look for obviously irrelevant terms. Look for terms that get clicks but never convert. A keyword might be technically relevant to your business but attract the wrong intent. Those clicks are costing you money for nothing.
2. Improve Your Quality Score
Quality Score remains one of the most effective levers for reducing CPCs. Google rewards advertisers who provide a good user experience with lower costs per click. The three components — expected click-through rate, ad relevance, and landing page experience — are all within your control.
Focus on landing page speed and relevance first. A landing page that loads in under 2 seconds, directly addresses the search query, and has a clear call to action will outperform a generic homepage every time. Then work on ad copy that tightly matches the keyword intent.
A Quality Score improvement from 5 to 7 can reduce your CPC by 28% for the same ad position. That's not a marginal gain — it's transformative at scale.
3. Reconsider Automated Bidding
If you're using Maximise Clicks or Maximise Conversions without constraints, consider switching to manual CPC or adding bid caps. Automated bidding works well for accounts with lots of conversion data, but for smaller accounts it often overpays.
At minimum, set maximum CPC limits on your automated strategies. This gives the algorithm room to optimise while preventing it from paying £12 for a click that you'd have been happy to get for £5.
4. Block Click Fraud
This is the highest-ROI action most advertisers aren't taking. If 20% of your clicks are fraudulent, blocking that fraud effectively gives you a 20% budget increase overnight — without spending a penny more.
Click fraud protection tools monitor your ad traffic in real time, identify fraudulent visitors through fingerprinting and behavioural analysis, and automatically block them from seeing your ads again. The blocked IPs are pushed to your Google Ads IP exclusion lists so the fraud is stopped at the source.
For many businesses, the cost of click fraud protection pays for itself within the first week.
5. Focus on Long-Tail Keywords
Head terms — short, broad keywords — are where CPC competition is fiercest. Long-tail keywords (3-5 word phrases with specific intent) typically have much lower CPCs and often convert better because the searcher knows exactly what they want.
Instead of bidding on "solicitor London," try "commercial lease solicitor Islington" or "employment tribunal solicitor near me." The search volume is lower, but the intent is stronger and the competition is lighter.
6. Daypart and Geo-Target Aggressively
If your business operates 9-5, why are your ads running at 3am? If you serve customers within 30 miles, why are you targeting the whole country? Tightening your targeting reduces wasted clicks from people who were never going to convert.
Use your historical data to identify the days and hours that produce the most conversions, then weight your budget toward those periods. Reduce bids or pause ads entirely during low-performing times.
7. Track Everything and Cut What Doesn't Convert
This sounds obvious, but a shocking number of Google Ads accounts don't have proper conversion tracking. Without it, you're flying blind — you can see clicks and cost but have no idea which keywords, ads, or campaigns are actually generating business.
Set up conversion tracking for every meaningful action: form submissions, phone calls, purchases, live chat conversations. Then ruthlessly cut or reduce spend on keywords and campaigns that get clicks but don't convert. The money you save can be reinvested in what's actually working.
The Bigger Picture
Rising CPCs are the new normal. They're unlikely to come down because the forces driving them — more competition, platform economics, increasing sophistication — are structural, not cyclical.
But that doesn't mean you're powerless. The businesses that thrive with Google Ads in this environment are the ones that pay attention to waste: wasted spend on irrelevant terms, wasted budget on fraudulent clicks, wasted money on campaigns that don't convert.
Every pound you save on waste is a pound you can spend on genuine growth. And in a world of rising CPCs, that efficiency is your competitive advantage.
