PPC Waste Reduction Case Study: Cutting Lost Spend

PPC Waste Reduction Case Study: Cutting Lost Spend
This PPC waste reduction case study shows how tighter targeting, cleaner data and better landing pages can cut wasted spend without starving lead flow.

A healthy Google Ads budget can still be leaking money every day. The issue is rarely one dramatic mistake. More often, it is hundreds of small decisions: broad search terms, duplicate conversion actions, poor location settings and ads sending every visitor to the same generic page.

This PPC waste reduction case study looks at how an established UK service business reduced unproductive spend without simply switching campaigns off and watching lead volume fall. The numbers are rounded, but the process reflects the practical account work that makes the difference between activity and profitable lead generation.

The starting point: leads were coming in, but costs were rising

The business operated in a competitive, high-value service market. Google Ads had been running for several years, managed internally and then passed between agencies. Spend sat at roughly £7,500 per month, and reports appeared reasonably positive: clicks were increasing, form submissions were being recorded and the account was regularly described as “optimised”.

The commercial picture was less convincing. The sales team felt that too many enquiries were outside its service area, unsuitable for the work, or simply price shopping. Cost per lead had risen from around £68 to £112 over nine months, while the number of qualified opportunities had barely changed.

That distinction matters. A cheap form fill is not necessarily a useful lead. If the person cannot be served, has no budget or is looking for something entirely different, it should not be used to judge campaign performance.

Before changing bids or budgets, the first job was to find out where the spend was actually going and whether the data could be trusted.

What the account audit found

The wasted budget was spread across several areas. None of them was unusual on its own. Together, they were costing the business a meaningful share of its monthly spend.

Search terms were too broad

Several campaigns relied heavily on broad-match keywords without enough guardrails. That meant ads appeared for research-led searches, job seekers, people looking for DIY guidance and searches for adjacent services the business did not offer.

One high-spend keyword produced traffic from more than 180 different search terms in a 30-day period. Only a small proportion showed a clear intention to buy the service. The rest generated clicks because the wording looked related to Google, not because it was commercially relevant.

Broad match is not automatically a problem. It can find valuable demand that exact-match campaigns miss. But it needs a clear strategy, strong conversion data and regular search-term management. Used as a default setting, it can become an expensive way to learn what customers do not want.

Location targeting was wider than the business could support

The client served a defined region but had location settings configured to include people “interested in” that area. As a result, ads could show to users based elsewhere who were researching the location rather than seeking a local supplier.

This is a common source of wasted PPC spend for local and regional businesses. It is not enough to draw a radius on a map and assume every click comes from within it. Settings need to reflect where potential customers are physically located, alongside any genuinely valuable exceptions.

Conversion tracking counted weak signals as success

The account recorded several actions as conversions, including page views after a form submission, clicks on an email address and visits to a contact page. This inflated the number of reported conversions and gave automated bidding poor information.

The bidding strategy had been trained to pursue the easiest actions, not the leads most likely to become customers. It was doing exactly what it had been asked to do.

We separated primary lead actions from softer engagement signals. Completed enquiry forms and calls above a meaningful duration became the main conversion actions. Contact-page visits and email clicks remained useful for reporting but no longer influenced bidding decisions.

Landing pages did not match the search intent

Most ads sent traffic to one general service page. It listed several offerings, offered little proof of location coverage and asked visitors to complete a long form before explaining what would happen next.

A person searching for a specific service should land on a page that addresses that service directly. This does not require dozens of pages or a redesign for its own sake. It does require a clear message, evidence that the business is relevant, and a straightforward next step.

The PPC waste reduction plan

The aim was not to chase a lower cost per click at any cost. Cheap traffic can be just as wasteful as expensive traffic if it does not turn into worthwhile enquiries. The target was to improve the proportion of budget reaching people with a real reason to enquire.

First, search-term reports were reviewed at campaign and ad-group level. Irrelevant themes were added as negative keywords, while useful specific searches were moved into their own tightly themed groups. This gave the team more control over ad copy, bids and landing-page relevance.

Second, campaigns were split by commercial value and service area. Previously, high-intent searches and vague research queries competed within the same budgets. Separating them made it easier to protect the terms that consistently created qualified enquiries, while limiting spend on exploratory traffic.

Third, geo-targeting was tightened to focus on users present in the areas the client could serve. Location reports were then checked weekly during the initial period. This was important because service areas were not uniform: some postcodes generated profitable work, while others created travel costs that made smaller jobs unviable.

Finally, landing pages were improved for the two highest-value services. The revised pages used service-specific headings, clearer qualification information, visible phone options and shorter forms. The business also made response times clearer, which helped reduce enquiries from people expecting an immediate quote for work that needed an assessment first.

The account was not transformed by a single clever setting. Performance improved because the work removed obvious waste, then made the remaining campaigns easier to manage properly.

Monthly spend fell from roughly £7,500 to £6,350. At the same time, recorded primary leads rose from 67 to 74 per month. More importantly, the sales team judged 58% of these leads as qualified, compared with 39% before the changes.

The cost per recorded primary lead dropped from £112 to around £86. The cost per qualified lead fell more sharply, from approximately £287 to £148. That is the figure the business cared about, because it reflected the cost of creating an opportunity the sales team could actually pursue.

Click volume declined, which can look worrying in a superficial report. It was the right outcome. A smaller number of better-matched visitors is more valuable than a larger audience made up of irrelevant searches, out-of-area users and accidental conversions.

There were trade-offs. Some broad-match activity was retained because it continued to uncover profitable searches that would not have been found through exact match alone. Branded campaigns also remained active, even though they made headline performance look stronger than non-brand activity. They were separated in reporting so the business could see their true role rather than giving them credit for demand created elsewhere.

What business owners should take from this

If your PPC report shows clicks, impressions and conversions but cannot explain lead quality, you are only seeing part of the picture. The most useful question is not “Are we getting leads?” It is “Which campaigns are producing the enquiries our sales team wants to handle?”

Start by checking the search terms that triggered your ads. Look at where your visitors were actually located. Review every conversion action and decide whether it represents a genuine business opportunity or merely interest. Then compare campaign data with what happens after the enquiry reaches your team.

This work is not glamorous, but it is where a great deal of paid-search value is won or lost. For businesses spending meaningful sums each month, a focused account review can often reveal whether the issue is budget, targeting, tracking, landing pages or the gap between marketing reports and sales reality.

The right PPC account should not just spend efficiently. It should give you a clearer view of what customers are looking for, where profitable demand sits and where your next pound is most likely to produce a real conversation.
