There are genealogy software programs. They provide a structure to properly post and access your family trees online. Several offer free versions, but most will eventually want money to keep your trees when you reach a certain point. That said, if you are going to keep your tree online you'll need to use one of these systems and it's better to start on the system you intend to keep on with rather than have to re-enter information. For example, Legacy Family Tree, RootsMagic, and Ancestral Quest offer free versions to start with and were all recommended on the Genealogy Do-Over Facebook group that helped me with suggestions on what to update, but I haven't used any of them.
Another big concern is privacy, especially for living people. It's always a bit shocking to find yourself listed on somebody's tree for the first time when you didn't know they put you there. So consider that when thinking about what to make public online.
Don't keep your only copy of anything online as formats change and websites go dead or get hacked.
This pathfinder will be useful for beginners who would like to start a family history search using the Internet. On a cautionary note, remember that the Internet is merely a vehicle to help you begin the process. It is not the only resource you should use, but is a wonderful road map to help you start your ancestry search. Some resources are free, others require subscriptions.
(Check with your state’s Genealogical Society & both state and local historical societies where your family lived, plus any ethnic heritage national museums – for example the National Czech and Slovak Museum or the Vesterheim - that apply)

NOTE: Most public libraries are organized by Dewey Decimal System or one related to bookstores. A lot of university libraries are organized their books using the Library of Congress system (designed to follow Thomas Jefferson's library in Monticello.) You will find people who prefer either one or the other. A genealogist in the group recommends this instruction set on how to use Library of Congress system for genealogy if you haven't had to deal with it before.
