Hero-Carbon is one of the leaders of custom lightweight carbon parts for bikes. Owners turned to the Drupal agency arocom.de in Stuttgart with the request to bring the site up to date, correct some problems, and increase the SEO conversion rate. It was at this point that we discovered, that the site has been built with serious violations of Drupal standards, including a strongly misused template system with business logic and even content hard-coded into it. We have done a massive set of corrections and clean up, cleaning up and correcting everything, that could be fixed without having to redo the whole web site. We have also done some changes to the UX, and the commerce part, adding support for the EU tax.
