Creating and maintaining an online presence is an important step in building your research profile, and in actively promoting your scholarship. Educators and researchers who are interested in seeking wider audiences, connecting with other scholars, or simply communicating their research so it can be discovered and used by others all need a strong online presence.
These first options are your best bet for getting started in building an online presence. They are free, easy to use, immediately connect you with other researchers, and take very little effort to maintain. Anyone looking to start building their online presence should start here.
These tools take a little more time to get setup and populated, and are worth investing in only after you have established your initial presence. Each offers advanced features to build rich profiles.
