Absolutely.
I am not going to put examples in because search results change all of the time. Check it out for yourself. The best examples of showing biased results is asking the following:
Ask Microsoft Bing which engine is better: Ecosia or Startpage?
Do the same with Google.
The guts behind Ecosia is Bing. The guts behind Startpage is Google. You will find more positive articles about Google (Startpage) from Google and you will find more positive articles about Bing (Ecosia) from Bing.
I find it hilarious. The reason Google and Bing care is because when search engines use another major search engine they have to pay to do so. You can do simple searches without payment with Python but to do so on a mass scale, you would be blocked and need to pay them.
