Showing me the products like that are so annoying, because google doesn't know I purchased them elsewhere and keeps showing them forever.

Please, after a reasonable time try to show me things people who have brought X typically buy after 2 weeks. As an example I would have paid for a curtain service to my new appartment, but google kept pushing (bad, paid) apartment search sites at me.

I now google products only in incongnito mode, since it get so annoyed by this behaviour.

Facebook decided initially that as I was single I must be interested in paid dating sites (even though, statistically I would be better of with a site with a larger audience), so please don't take this as an attack on Google, but as an attack on limited machine learning.
