Haven't heard of those stories yet, Baidu is similar to Google but the Link Quality doesn't have such a high factor than it has on Google YET.
It definetely is easier to rank for Baidu than it is to rank on Google. But you always gotta first look at the competition, check how other sites are performing in your niche and analyze their site.
What i mean is, that this is a pretty bold statement to say when Baidu is ranking for #1 most visited websites in China and #4 globally according to SimilarWeb.
Are you Chinese or do you live in China? If not, You can find examples about how the Chinese use the internet or how the brands are promoted in China.
You can say Baidu=Google, but Baidu is not as important for the internet here as Google is.
A Chinese person can stay more than 1 day without using Baidu, while the average use of Wechat is more than 70 minutes every day, and has more than 1billion active users.
A lot of companies doesn't have a web here or they have a crappy one and they don't care, but everyone has an account in Wechat.
Google is super important in western, but here everything is divided between 3 companies Alibaba, Wechat and Baidu, (NetEase is also very important) but if you want to sell something/improve your awareness here, normally the strategy is work with your image in Wechat, work with Weibo(alibaba) and perhaps with douyin (tik tok)
Im not saying that what you say is not right,but for selling to another country firstly you have to understand the consumers. My only purpose here is to help the OP
