From Incognito window's note
> Others who use this device won’t see your activity, so you can browse more privately. This won't change how data is collected by websites you visit and the services they use, including Google. Downloads, bookmarks and reading list items will be saved
Incognito does not hide your activity from Google. Especially when you googled in incognito and they likely use IP addresses as part of their targeting. I am also assuming it's different for different kinds of ads given you wont see ads if you look at something personal. They infact allow IP address targeting somehow. [1] Their privacy stance is more about 3rd party not having access to the data google has collected.
