Advertisement website – USA AUTO ONLINE


Advertisement website redesigned. As a result: 100 times faster page display while serving 4 times more auctions. USA Auto Online provides nearly 125,000 US car sales offers per day. To handle a growing number of visiting users, our client needed specific improvement of his website.


The Challenge


Customer’s business has grown substantially in a relatively small period of time. As USA Auto Online strives to run its services providing exceptional experience both in terms of accessibility and performance to its demanding customers, it was clear that their current portal will no longer be able to handle such a number of visiting users. Another reason was their need to grow and extend their offer – that wasn’t possible with their current solution.


The Solution


We rebuilt the existing auction portal using the newest technology and IT standards. The new site was implemented on Umbraco CMS – a fully-featured open source content management system. Umbraco CMS gives you the freedom to build websites, apps, or other solutions exactly the way you want. That allowed the client to modify content and update actions without external support. For a better user experience, we also optimized the search engine module to get the best possible performance.

Frontend part was built as Single Page Application (SPA), meaning that after clicking links, the page will change instantly without reloading. Despite being dynamic, its rendering is Isomorphic, serving the initial page in HTML for improved SEO and first load speed. The application was built according to Responsive Web Design (RWD) so it automatically adapts for both mobile and desktop devices. All of this increased the user experience of browsing web content.

As part of the advertisement website, we implemented a blog module where customer’s content editors promote different car models. Also, a detailed cost calculator was built where the end-user can calculate the exact cost of bringing a vehicle from USA directly to his home. As a result, our team delivered a modern website layout with restructured website content and a settled, intuitive navigation structure.


The Outcome


As a result, the average time of displaying the page with auctions was 10 times faster and for complex queries with filters even 100 times faster. Fetching the auction updates file was optimized from 2h to 7 minutes which enabled keeping the site up to date. Everything was achieved on a machine with 10 times less RAM and 8 times less CPU. Thanks to those performance changes, we were able to process and expose to end-users 4 times more auctions than on the old page.

There have been cost optimization due to the use of hosting in the cloud (Azure Cloud was selected). Our client does not bear the costs of updating and the server and does not need additional supervision which decreased the maintenance and support costs (which were used to improve site SEO). The improved performance allowed our client to launch marketing campaigns to generate additional traffic. Customers are spending much more time on the new website looking for cars. This allowed the owner to think about new ideas that can improve his customers’ journey even further and increase the conversion rate by 30%.
