Which Search Engines Can be Analyzed in Semrush?
Most of our tools work only with Google search engine. For search engine rankings and keyword analytics, we use third-party data providers to collect Google’s actual search results pages for the 543 million most popular keywords. We study both organic search results, as well as paid search results to give you a complete picture of any website’s visibility on Google.
In the Position tracking tool, you can track your keywords positions on Google, Baidu, Bing (top 50 results on SERP), and ChatGPT.
The Traffic & Market toolkit allows you to estimate how much traffic a website receives from different search engines such as Google, DuckDuckGo, Bing, Yandex, Baidu, etc, depending on the filters you apply (Date, Location, Devices).
