As we see it, this experiment confirms our suspicion that Bing is using some combination of:
or possibly some other means to send data to Bing on what people search for on Google and the Google search results they click.
- Internet Explorer 8, which can send data to Microsoft via its Suggested Sites feature
- the Bing Toolbar, which can send data via Microsoft’s Customer Experience Improvement Program
It could be that Bing is smart enough to crawl those pages as well.
What do you think?
