Our research team recently conducted an analysis of the market share each of the major search engines in the US B2B market. Whereas Statcounter, Similarweb, and Statista have long published overall search engine market share statistics, no datasets have been compiled to examine search engine share specifically through the B2B lens.
We define “search engine” as any application on a computer or mobile device where users search for information on purchasing business services or software. Our definition blends traditional search engines like Google, Yahoo, and Bing with AI chatbots and “answer generators” like ChatGPT, Claude, and Perplexity.
The tables below display the top B2B search engines by market share in the US as of 2024, as well as the fastest growing B2B search engines in the US.

B2B Search Engine Market Share vs Overall Search Engine Market Share, 2024
In the pie charts below, we compare B2B-specific search engine market share to overall search engine market share, as sourced from Similarweb. The main difference is that, in the B2B realm, smaller search engines have cut into Google’s market share in a small but meaningful way in the last few years. By comparison, the overall search market is still dominated by Google, with even the likes of ChatGPT not having much impact.

While Google remains dominant in B2B search, it has less room to grow than AI upstarts like Perplexity, Clause, and ChatGPT; or privacy-focused search engines like Brave and DuckDuckGo.
