Bard isn’t being taken seriously by google and it shows, which is alarming since this is their apparent strategy to deal with LLMs. If I was in charge of that project and I chatted with Bard on launch day, then I would never have made it public because it’s too embarrassingly stupid (!) of an Intelligence model to be ready. Not even alpha or beta!!!

These links were probably shared to a site that was crawled by Google and indexed. I don't think this can happen with your personal queries shared with friends or in a closed circle.
