Real results from Google Ads campaigns managed by Digitalhound's paid search team -- reduced cost per sale, increased conversions, and measurable revenue growth across competitive markets.

Why PPC done properly matters

Most businesses running Google Ads are leaving money on the table. Poor campaign structure, unfocused bidding, and untracked conversions mean budgets are spent without a clear return. Digitalhound's paid search team takes over underperforming campaigns and rebuilds them around what actually drives revenue.

Client results

Three campaigns. Three transformations.

Each of the campaigns below was inherited in a state of underperformance. In each case, a thorough audit, structural rebuild, and ongoing optimisation produced results that materially changed the commercial outcome for the client.

Case Study 01

Online Electrical Wholesaler

When Digitalhound took over this account, the campaign was generating an average monthly revenue of £10,165. The campaign had never been properly structured around conversion data, and significant budget was being wasted on poorly matched search terms.

Following a full audit of performance and conversion data, the entire campaign was rebuilt. Bidding strategy was realigned to the most profitable product categories, negative keywords were expanded significantly, and ad copy was rewritten to improve click-through and conversion rates.

Within the second full month under new management, monthly revenue had risen to £13,500 with no increase in spend. After 12 months of ongoing optimisation, average monthly revenue had risen to around £22,000 -- more than double the starting point, with only a modest budget increase.

Case Study 02

Car Insurance Broker

Car insurance is one of the most competitive and expensive PPC markets in the UK. When Digitalhound took over this campaign, the client was generating 275 sales per month at a cost per sale of £130 -- a figure that was eroding margin and making the channel borderline viable.

The team applied deep account management expertise to restructure the campaign around the highest-performing ad groups, tighten audience targeting, and improve the quality of traffic being sent to the site. Conversion tracking was reviewed and attribution improved to ensure bidding decisions were based on accurate data.

Within six months, cost per sale had dropped from £130 to £80. By the end of the first year, the team had grown total monthly sales from 275 to 462 -- a 68% increase -- while simultaneously reducing the cost of acquiring each one by 38%.

Case Study 03

Online Outdoor Wear Retailer

This ecommerce campaign was producing an average of 62 conversions per week at a cost per conversion of £20.33. The budget was being spread too thinly across a wide range of product categories, diluting performance across the board.

The Digitalhound team took over the account and restructured it to focus entirely on conversions, directing budget to the product categories and audience segments with the strongest return. Underperforming ad groups were paused, and spend was concentrated on what was demonstrably working.

The campaign subsequently improved to an average of 94 conversions per week at a cost per conversion of just £11.74 -- a 51% increase in weekly conversions and a 42% reduction in cost per sale delivered simultaneously.

Travel Guide Website

This travel sector campaign was focused on lead generation rather than direct ecommerce sales -- with conversions defined as enquiries about holiday offers. Strong results came quickly here, with meaningful improvements emerging within just two months of taking over the account.

By analysing the conversion data and optimising the campaign structure and bidding around the highest-intent audience segments, the team was able to increase the total number of weekly lead conversions by 45% and improve the average click-to-lead conversion rate by 30%.

The speed of improvement reflected both the quality of the existing traffic and the significant gains available through sharper campaign management and conversion-focused optimisation.

Our approach

How we turn underperforming campaigns around

Every campaign we take over follows the same diagnostic-first methodology. We never make changes for the sake of activity -- every action is driven by data and tied to a measurable commercial outcome.

01

Full account audit

We start by understanding exactly what is and is not working -- campaign structure, bidding strategy, keyword match types, negative lists, quality scores, and conversion tracking accuracy.

02

Conversion data analysis

We interrogate the conversion data before changing anything. Poor attribution is one of the most common reasons campaigns underperform -- fixing this first means every subsequent decision is based on reality.

03

Budget reallocation

We redirect spend to what is demonstrably working. Most accounts have significant budget going to low-return activity -- freeing that spend for high-performing campaigns and ad groups delivers immediate results.

04

Ongoing optimisation

PPC management is not a set-and-forget discipline. We review performance continuously, test new approaches methodically, and compound gains over time rather than chasing short-term spikes.
