About the client

Motorwise: free scrap car collection across the UK.

Motorwise is a UK scrap and salvage car service based in Poole. A driver enters their registration on motorwise.com, gets an instant online quote for a scrap, damaged or unwanted car or van, and accepts it. The Motorwise website says the approved buyer then phones within four business hours to book a free collection anywhere in the UK.

Motorwise says it works with Authorised Treatment Facilities licensed by the Environment Agency, Natural Resources Wales or the Scottish Environment Protection Agency, and that a Certificate of Destruction is issued for every scrapped vehicle.

The scrap car market is one where people tend to search in a hurry. A car has failed its MOT, been written off or simply reached the end of its life, and the owner wants a price and a collection date without a long process. Because the service is the same wherever the car is, a great many firms compete for the same searches across the country, and clicks in this market can climb in price when several of them bid on the same terms.

That is why the shape of the account matters so much. A business that wins customers by quoting them online lives or dies by the cost of each quote that turns into a collected car. If the account is set up poorly, costs can drift upward long before anyone notices, and the more a business invests in growing, the more that drift costs.

For a business that wins customers by enquiry, cost per acquisition (CPA) is the number that decides whether Google Ads is profitable. Motorwise has been a DPOM client since July 2019: we started with Google Ads, added SEO in January 2020 and social media advertising in May 2021, and look after all three today.

The challenge

Cost per acquisition was spiralling to unprofitable levels.

Motorwise arrived at DPOM with a difficult set-up in its Google Ads account. CPAs, what each conversion costs, were spiralling to unprofitable levels.

We were asked to iron out the rising CPAs while improving other key metrics, in order to power Motorwise's multi-channel marketing. Cutting spend is the easy way to lower a cost, but it also cuts the enquiries coming in, so the job was to bring CPA down without losing the return.

What the brief asked for

  • Bring CPA downCPAs were spiralling to unprofitable levels, so the first job was to bring them back under control.
  • Keep the return positiveThe foundations of the account had to be levelled out while it kept a positive return on investment.
  • Improve the other key metricsLower CPA was not the only target. Conversions and conversion rate had to move the right way too, to power Motorwise's wider marketing.

What we did

Level the foundations first, then grow.

Our approach was to level out the foundations of the account while maintaining a positive ROI, which led to further increases in key metrics, and then to look for more conversions in other target areas.

The approach, step by step

  1. Step 1Level out the foundationsWe started with the difficult set-up Motorwise arrived with, because the rest of the work depends on a stable account.
  2. Step 2Keep the return positiveEvery change was made while maintaining a positive ROI, so the account kept paying its way as CPA came down.
  3. Step 3Raise Quality Score, tune bids and budgetsQuality Score rose by 35%, and bids and budgets were optimised alongside it.
    More detail

    Quality Score is Google's rating of how relevant your keywords, ads and landing pages are to what people search for. It is one of the things that affects the price you pay per click and where your ads appear.

    As Quality Score improved and bids and budgets were optimised, costs dropped, which increased ROI.

  4. Step 4Look for conversions in other target areasWith the foundations steady and the key metrics rising, we looked to increase conversion numbers in other target areas.

The results

Lower CPA, lower costs and more conversions.

Quality Score has risen by 35% and average CPA has dropped to record levels. Because of the Quality Score improvements and the optimisation of bids and budgets, costs have also dropped, resulting in increased ROI.

Put together, the account now costs 17% less to run and each conversion costs 17% less, while conversions are up 6% and the conversion rate is up 17%.

What each figure means

  • Conversions up 6%The account recorded 6% more conversions, even though its costs fell.
  • CPA down 17%Each conversion cost 17% less to win. This was the problem Motorwise came to us with.
  • Conversion rate up 17%A larger share of the people who clicked went on to convert, so the clicks Motorwise paid for worked harder.
  • Costs down 17%The account cost 17% less to run, with Quality Score and bid and budget optimisation behind the fall.

What the client said

In Motorwise's own words.

…he took the time to really understand the unique challenges of our business model rather than try to impose a cookie-cutter approach to our Google PPC. Without exception I have found him approachable, very quick to respond (literally within minutes!) and his team at DPOM have come up with some great initiatives which have kept our CPA down.
Jackie Usher, Motorwise Feefo review, 22 June 2023
Having proved themselves with Google PPC management, I contracted them to assist with our SEO and social media and have enjoyed the same service and great results. I would 100% recommend DPOM for a professional, friendly, result achieving Digital Marketing partner.

Case study FAQs

Questions about this case study.

About this result

What is CPA in Google Ads?

CPA stands for cost per acquisition: the ad cost divided by the number of conversions, such as quote requests or calls. If CPA rises above what a conversion is worth to the business, the ads stop paying for themselves.

What is Quality Score?

Quality Score is Google's rating, out of 10, of how relevant your keywords, ads and landing pages are to what people search for. It is one of the things that affects the price you pay per click and where your ads appear. On this account it rose by 35%.

Can you promise the same result for my business?

No. Every account starts from a different place. These figures are what happened for Motorwise, not a promise of what will happen for you.
