Re: the right people
It is more a matter of "the right time". If I am reading the news then I am not buying anything. If I am buying something I will use my list of URLs to get to a company the sells what I am after and type key words into the site's search box to get to the right product. All of this works without massive databases of every website that anyone has ever looked at or complicated algorithms find and excuse to deflate the fattest advertising budgets.
