In 2019, Gerasimenko announced Ahrefs would be building a search engine to compete with Google. The main differentiator would be a focus on privacy similar to DuckDuckGo and profit sharing, with 90% of profits would go to publishers of the indexed content.Reactions to the announcement were generally positive. Some search marketers expressed skepticism due to the focus on the search engine's publishers rather than users.
