Many ecommerce companies sell your purchase history to third parties as well, just like the credit card companies.  This allows others to market to you more directly.&lt;p&gt;There is at least one company that has built technology that will monitor most all these purchases, monitor the IP&amp;#x27;s from them and the browser profile to identify a specific machine that you use.  Then when you go to work, or are on your mobile they also will tag that traffic as you too.  They have gotten so good they can serve ads that are relevant to your wife if she happens to be on your computer surfing the web for shoes say, but serve you different ads if you are on the same computer.  They use data feeds from many sources, but ecommerce transactions, credit card transactions and companies like acxiom that let them match those with real people, incomes and household details make it very powerful.&lt;p&gt;In marketing we use Axiom and others a lot, their data used to be more vague and educated guesses about people.  Now though, they have gotten it down pretty well, including how many animals, kids and your income&amp;#x2F;debt etc.  They collect data from tax collectors offices, county records, city records, plus companies that will sell transaction data and other pieces so they can get a full picture.  They of course work with Equifax, TransUnion etc too so they can build a whole economic profile on a person.&lt;p&gt;These companies are also what allow marketers to send you an email about their product&amp;#x2F;company after all you have done is visited their website.  You don&amp;#x27;t have to enter anything or click on anything, but they will know who you are, who you work for and whether you fit their market profile in general.  Poorly done it is extremely creepy, correctly done it can be an amazing conversion booster.</text><parent_chain><item><author>dcposch</author><text>I assumed that when I buy something on a card, it&amp;#x27;s more or less private.

Banks and credit card companies merchandise this information to their partners, which leads to this kind of thing.  Check your cards&amp;#x27; terms of services if you want to be somewhat horrified.</text><parent_chain><item><author>dcposch</author><text>I assumed that when I buy something on a card, it&amp;#x27;s more or less private.
