SpyOnWeb

Want to know what other websites someone else owns or works on? Thanks to SpyOnWeb you can get a pretty good idea of what other websites someone owns or is involved with. Just enter the URL of the website you want to know about and SpyOnWeb will return the other website names that are associated with that address. SpyOnWeb does more than just look up the sites that are on the same IP address though, it will look for sites that have the same AdSense publisher id and the same Google Analytics ID. This gives you a much better idea of what other sites a person is involved in.

This service is similar to another one I talked about at one time called You Get Signal. You Get Signal only returns the other websites that are on the same IP address though. If the persons website is on shared web hosting then there is no guarantee that the other websites are theirs or belong to someone else. The fact that SpyOnWeb checks not just for IP addresses but also Google AdSense and Analytics ID’s give it a better percentage that the sites it returns will be have something to do with the same person.

There is a lot of information you can find with a tool like this and while it can be fun to see what other websites people have, it may not be totally accurate as well. For example, some of the sites that it returns for me are not my personal websites, but my clients websites. Yes I do have something to do with the site, but it is not my website. There were also some websites returned that are no longer mine or on my server. Overall it can be a useful tool, especially if you are wondering what else your competition might be up too. Remember to play nice though. Like Search Engine Journal says:

I don’t advise though to use this tool for any malicious purposes.

I read about this service thanks to a post over at Search Engine Journal.
