How to Use the Invisible Web to Find People

Try these top people search sites to gather hard-to-find information

When you want to know how to find someone, the invisible web is a wonderfully detailed treasury of data, yielding information that generalized searches are not able to provide. The invisible web is a gold mine of information you can use to find someone, and because it is larger by far than the parts of the web you can access with a simple search engine query, it potentially has much more information available. 

You need specialized websites to delve deep into the invisible web. The top people-search sites for the invisible web listed here can make your people searches richer, more detailed, and authoritative.

Internet Archive Wayback Machine

If the person you're looking for has ever created a website or has information you know was on the web but has been since deleted, you can look that website up via the Wayback Machine, a database of over 150 billion pages archived from 1996 to the present.

This is a good way to view hard-to-find information, as screenshots of millions of websites – including many that are no longer live on the internet – have been archived here.

FamilySearch, one of the largest collection of genealogical and historical records in the world, is primarily a genealogy tracker, which makes it an invaluable people search tool as well.

Type in as much information as you know, and FamilySearch returns birth and death records, parental information, and more. Digital preservation, digital conversion, general preservation of records, and online indexing is available here as well – all at no charge
