The Challenge’s biggest competitors have more domain authority, much of that due to them being considerably older. While this put InvestmentU at a disadvantage on organic search, they compensated by improving other areas of SEO optimization.

That all changed when Google rolled out a Core Web Vitals update in June 2021. They now had a new disadvantage. They failed the CWV’s overall score, which significantly hurt their SEO optimization across the board.

The Transformation

oneRhino undertook the substantial task of optimizing all of InvetsmentU’s 4000 pages, which meant changes in the server, middleware, and frontend code and design, with the goal of passing Core Web Vitals and regaining or surpassing past SEO page ranking. All of this was done with a careful eye to not degrade any revenue-generating endeavors, such as complex analytics configuration and tracking, or other conversion improvements.
