Does anyone know a good tracking tool that allows me to discover the exact urls my visitors go to after they hit my site? Perhaps something that cookies them and then returns a report of aggregated urls they visited in the last 30 days?
There are two reasons (at least) to have this knowledge. The first is I may discover non-obvious offers they are interested in- for example, most of my traffic is dating traffic (male) but if I see that a decent percentage of them went to, say, fantasy football sites, that leads to non obvious offers (I'm an email marketer, so I can drive traffic back to non-obvious offers).
The second reason is discovery of non-obvious media. If, as in the prior example, they visit fantasy football sites, then those sites may be worth running banner ads for dating, etc.
Anyways, I'd like to have that knowledge for a variety of reasons, does anyone know a way to get this? Google Analytics will show channels, but those are pretty vague and general (autos, financial services, etc.)
I'm not aware of any major tool or service that provides such a thing directly to 3rd parties - that sounds like a big privacy issue honestly.
However I imagine adware/toolbars and extensions would have this sort of functionality available.
Perhaps you could indirectly discover this sort of info from companies that provide or sell demographic/user data? DSPs I imagine would have tons of it. Or even sites like similarweb or others that provide interest profiles for sites or "also visited site X".
I'm unfamiliar with Big G and Facebook's platforms but I imagine the latter would have something of use there with lookalike audiences? Don't run there so can only guess.
Apart from similarweb mentioned above, you can also use this tool from Alexa

It’s essentially an audience overlap tool
There's also Similarweb:

SimilarWeb ^^^ is your best bet, though a bit pricey.
But you still can get some basic idea from the free version as well.
