Have you ever looked at Spokeo? If not, you might want to check it out – that is if you’re concerned about your online privacy. There’s a good chance they have a profile on you, and it may have more information than you care to have publicly accessible in any one place. And that’s just the free part, if you pay, you can get access to even more information.
The other day a person contacted me about wanting to help me with ad retargeting on one of my sites, but in order to do so they would have had to have tracked my site. That would have given them tons of great information about how they could retarget all my site’s visitors around the web. And they wanted me to give that up for free in an offer which was made to sound compelling, but lacked substance. And so they never got a response. 😀
