This is the exact reason why Google is so valuable- when I use Google, I&#x27;m actively searching for something, so I&#x27;m happy to see relevant ads in my search results.<p>If I search &quot;bike shop London,&quot; I want to find a bike shop in London, so if I see an ad for a bike shop in London, I&#x27;m ecstatic, and I&#x27;ll probably go there.<p>When I go to check my inbox, on the other hand, that&#x27;s because I want to see what email I&#x27;ve received. I don&#x27;t want to see ads there.<p>This is the inherent problem with Facebook&#x2F;Twitter- I go to Facebook&#x2F;Twitter to find what my friends are up to, not to search for something. I have no interest in seeing ads in my Facebook&#x2F;Twitter feed.
