The majority of users, at this point, will probably be using a fixed device. Either their PC at home, or their mobile phone, on their own phone service provider. Either stands a good chance of always having the same IP, or some other way of fingerprinting them. And considering just how widespread google is, for instance, you can go to *almost* *any* website, and there'll be some google content incorporated into it (virtually every website I looked at yesterday). Just like doubleclick used to be. Making it all the more easy to keep tabs on you. It's a trivial databasing exercise, if you're familiar with actual relational databases, rather than flat spreadsheet barebones types of databases that people use from day to day. One database of DNS queries from one IP. Another database of websearches from one IP. Get the computer to join the dots for the overlapping records. It's what databasing used to be about - what things in this set of records co-relate to things in this other set of records (relational databasing), as opposed to just pull up the single file on John Doe and read his record (flat files). Then carry on and do the same co-relation exercise across some other records. Since it's actually a trivial thing (co-relating records when you're the world's biggest database), I say it would be cost effective, if you're actually trying to drive sales from the advertising, rather than just throw advertising at someone that's going to be ignored. Particularly when you're making the advertiser pay per advert, they want value for their money, and want their adverts to go to likely customers. -- [tim@localhost ~]$ uname -rsvp Linux 3.9.10-100.fc17.x86_64 #1 SMP Sun Jul 14 01:31:27 UTC 2013 x86_64 Boilerplate: All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I only get to see the messages posted to the mailing list.
