This body shop was struggling to attract new customers with a poorly optimized website and zero advertising. The owners were working overtime to attract customers from offline methods, but it was not scalable and was negatively impacting the operations. The parking lot was less than 20% full and had enough labor capcaity to easily 4X the business.
Solution
Our team immediately pitched a new website, fully optimized with SEO and Conversion Rate Optimization using our Max Acquisition approach. We setup Paid Ads on Google Ads / Google LSA / Bing Ads. We knew OCT tracking phone calls / forms would be critical to training Google to improve smart bids, so we implemented Offline Conversion Tracking with Edge Tagging to maximize customer data throughput to Google.
Result
The new website was a huge success. Overnight on launching, the next week we saw existing organic traffic convert 3X greater than historical average. Paid Ads attracted new customers and we were able to 5X the total revenue of the business within 6 months. The owner of the business ended up renting out a second parking lot and hiring more employees to keep up with demand. He also picked up a Lamborghini for the shop's marketing.

Most vehicle wrap shops are not aware of RIP Software and the potential savings in time and cost. This makes it difficult to reach new B2B customers (vehicle shops) outside of conferences. Inside conferences, there's limited exposure to the entire market. The client needed a reliable way to advertise in front of their target customers. Targeting only keywords at bottom of funnel was not going to be enough volume. And at top of funnel they keywords are likely to have low volume.
Solution
IOI took a customer lifecycle approach. We analyzed what problems vehicle wrap shops faced and what they might search in that situation. We built a product-awareness marketing strategy from completely unaware to solution aware with multi-channel placement. We combined Google Ads with SEO Content strategically covering low volume keywords, publishing 120+ pages in advertorial style. Using Google Ads we ran dynamic content Ads to ensure maximum funnel coverage.
Result
5X their leads from what they normally see at a conference. Their sales team began working the relationships, and after 2-3 months closing high ACV deals for their software. In the first 15 months we added $3M in ACV to the business with this approach.
