If you're running Google Ads, you've probably noticed that clicks aren't getting any cheaper. CPCs have been climbing steadily across most industries, and the natural response is to wonder: what can I actually do about this?

The good news is that there's quite a lot you can do. Reducing your cost per click isn't about finding one secret lever — it's about getting several things right at the same time. Each improvement compounds on the others, and the cumulative effect can be significant.

Here's what actually works.

Start With Your Search Terms Report

This is the single highest-impact thing most advertisers aren't doing often enough. Your search terms report shows you the actual queries people typed before clicking your ad — and it's almost always eye-opening.

Google's keyword matching has become increasingly broad over the years. Even phrase match keywords now trigger for searches that are only loosely related to what you intended. That means you're likely paying for clicks from people who had no intention of buying what you sell.

Build a proper negative keyword list

Go through your search terms report at least weekly (daily if your budget allows it) and add irrelevant terms as negatives. Look for:

A well-maintained negative keyword list can cut wasted spend by 15-25%. That's not a small number — it directly reduces your effective CPC by eliminating clicks that were never going to convert.

Use the right match types

Broad match gives Google maximum freedom to show your ads for loosely related queries. That freedom comes at a cost. If you're struggling with CPC, consider tightening your match types:

There's no universal right answer here. The key is matching your match type strategy to your conversion volume and how actively you manage your account.

Improve Your Quality Score

Quality Score is Google's rating of the overall quality of your keywords, ads, and landing pages. It's scored 1-10, and it directly affects how much you pay per click. A higher Quality Score means you pay less for the same ad position.

Google calculates Quality Score from three components:

Expected click-through rate (CTR)

This is Google's prediction of how likely people are to click your ad. You improve it by writing compelling, specific ad copy that closely matches the searcher's intent. Generic ads get generic CTRs.

Practical steps:

Ad relevance

This measures how closely your ad matches the intent behind the keyword. The fix is structural: organise your campaigns into tightly themed ad groups where every keyword in the group relates closely to the ad copy.

If you've got an ad group with 30 keywords covering five different topics, your ad can't possibly be relevant to all of them. Break it down. Smaller, tighter ad groups with tailored ads will improve relevance scores and reduce your CPC.

Landing page experience

This is the one advertisers most often neglect. Google evaluates whether your landing page delivers on the promise of your ad. That means:

Improving your landing page experience is one of the most effective ways to reduce CPC because it affects every keyword in the campaign that points to that page.

Optimise Your Landing Pages

Beyond what Google measures for Quality Score, your landing pages affect CPC indirectly through conversion rates. A page that converts well means you get more value from each click, which lets you bid more strategically.

Focus on:

A landing page that loads in 2 seconds and converts at 5% is worth dramatically more than one that loads in 6 seconds and converts at 1.5%. The maths changes everything about what you can afford to bid.

Choose the Right Bid Strategy

Google's automated bid strategies are powerful, but they're not always the cheapest option. Understanding when to use each one matters.

Manual CPC

Gives you full control over what you bid on each keyword. Best for:

The downside is that it's time-intensive to manage and you'll miss some optimisation opportunities that automation would catch.

Maximise Clicks

Sets bids to get as many clicks as possible within your budget. Sounds sensible, but in practice it often bids higher than necessary. Always set a maximum CPC bid limit if you use this strategy.

Target CPA / Maximise Conversions

These work well when you have strong conversion data (50+ conversions per month as a minimum). They let Google's algorithm find the most efficient clicks. But be aware — they optimise for conversions, not for low CPCs. Sometimes the algorithm will pay a high CPC if it believes that click is likely to convert.

Target ROAS

The most sophisticated option, but requires robust revenue tracking. Only suitable for e-commerce or businesses that can accurately attribute revenue to clicks.

The practical advice: start with manual CPC or manual CPC with Enhanced CPC turned off. Once you have enough conversion data, test automated strategies in experiments before committing fully. And always set bid limits.

Use Dayparting and Geo-Targeting

Not all hours and locations are equal. Your CPC and conversion rate will vary significantly by time of day, day of week, and geographic area.

Dayparting (ad scheduling)

Look at your conversion data broken down by hour and day. You'll almost certainly find that some time slots perform far better than others. Common patterns:

You can set bid adjustments to reduce bids during poor-performing times, or pause ads entirely during hours that consistently waste money.

Geo-targeting

Similarly, your performance will vary by location. Drill into your geographic data and look for areas where CPCs are high but conversions are low. You can:

This kind of granular optimisation won't halve your CPC overnight, but it chips away at waste consistently.

Cut Out Fraudulent Clicks

Here's a factor that many advertisers overlook entirely: click fraud. A portion of your clicks — industry estimates suggest anywhere from 14% to over 30% — aren't from genuine potential customers. They're from bots, click farms, competitors, or other sources of invalid traffic.

When fraudulent clicks eat into your budget, two things happen. First, you're paying for clicks that have zero chance of converting. Second, the inflated click volume skews your performance data, making it harder to optimise effectively. Your reported CPC might be £2.50, but if 20% of those clicks are fraudulent, your real CPC — the cost per genuine human click — is more like £3.12.

Blocking fraudulent clicks doesn't just save wasted spend. It effectively reduces your CPC by ensuring more of your budget goes toward real prospects. It also gives you cleaner data to work with, which makes every other optimisation on this list more effective.

Google does have built-in invalid click detection, but it doesn't catch everything — particularly more sophisticated fraud like competitors clicking your ads or bot networks that mimic human behaviour. Dedicated click fraud protection tools fill that gap.

Putting It All Together

Reducing your CPC isn't a one-time project. It's an ongoing practice of tightening, testing, and refining. The advertisers who consistently pay less per click than their competitors are the ones who:

  1. Audit search terms regularly and maintain comprehensive negative keyword lists
  2. Structure campaigns tightly so ads are highly relevant to each keyword group
  3. Invest in landing page quality — speed, relevance, and conversion rate
  4. Choose bid strategies deliberately rather than defaulting to Google's recommendations
  5. Use scheduling and geo-targeting to focus spend on the times and places that convert
  6. Protect their budget from fraud so every pound goes toward genuine clicks

None of these steps is complicated on its own. The challenge is doing all of them consistently. But even implementing two or three of these properly can make a meaningful difference to your cost per click — and to how far your advertising budget actually stretches.
