KIA Parts UK Case Study

See how we help the specialist KIA parts provider

KIA Parts UK is a part of the TMS Motor Group company and they sell genuine KIA parts and spares through their ecommerce website. TMS Motor Group is a KIA dealer with showrooms in Hinckley and Leicester so they know their way around the KIA car range.


Kia Parts UK approached Key Principles to help grow their online Kia Parts business back in April 2016.

The challenge Kia Parts UK faced was tight margins on the parts in a competitive market. Having built up a base of trade customers, and parts purchases through organic listings, the owners decided to look at Google Ads to see if they could increase volumes as well as maintain a return on their investment.

Originally implemented in-house, they quickly realised they needed our expertise.


Key Principles implemented Google Ads Search and Shopping, as well as Bing Ads Search and Shopping. In recent times, we’ve also added Facebook Dynamic Product Listing Ads.

Optimisation of the Google Shopping feed, as well as management and optimisation of campaigns is on-going and continues to provide an ROI for the client.


Results shown are a year on year comparison, comparing 2018 vs. 2019.

To summarise, Key Principles have helped Kia Parts UK to sell more products through their ecommerce website whilst maintaining a very high return on ad spend (ROAS). We have also added in new campaigns and new digital channels to scale the volume of sales whilst maintaining a high ROAS.
