Our strategic approach offers opportunities and value - important criteria for our investors. In this aspect, we are - as always - strongly committed to delivering returns to our shareholders. The customers we serve continue to be centrally important inspiration for our strategy. Their future is also the story of the future of society at large. We can derive real pride in our work simply by recognizing how we contribute to making a difference every day.
The foundation laid over the past many years has driven improved organic growth and operating margins and helped us navigate the challenge of the global pandemic. While we were briefly diverted from our financial trajectory in 2020 due to the pandemic, the recovery seen in 2021 allowed us to meet nearly all of the financial goals set for the most recent strategic plan (2019-2021). We grew expert solutions from 49% of total revenues in 2018 to 55% of total revenues in 2021, primarily through organic growth. The acquisitions of CGE, XCM, Vanguard, and eOriginal, and the divestment of several non-core assets also helped increase our focus on expert solutions.
We made progress on enriching several of our information products and are now starting to launch the early results of that effort. We also made progress on our third goal, which was to drive operational agility, by completing several major internal projects, such as the introduction of a modernized global HR system in 2019, the consolidation of 280 customer-facing websites into a single global site in 2021, and the implementation of CCH Tagetik as our new corporate performance management tool in 2021.
