Things to keep in mind when creating your portfolio:
As you evaluate which website builder to use, keep in mind some of the following items:
Most free services require advertisements of some kind on your web pages in exchange for the free service. Pick a service that is less obtrusive in their advertising. The domain name of your site will also have the name of whichever service you pick in most cases.
Google Sites allows you to limit who can view to individual people or the Chesapeake College community. JimDo allows you to password-protect pages if you want to, limiting who has access - Weebly charges for this feature.
JimDo and Weebly offers apps for Android and iOS that allow you to do some editing on those devices while Google Sites does not.
While both are pretty straightforward, Weebly and JimDo are generally considered a bit easier to learn than Google Sites because of their simplified interface. However - Google Sites has recently revamped their interface making it much more inline with Google Docs (very simple and clean).
Google Sites, JimDo and Weebly can embed Youtube Videos PDF files. Google Sites integrates well with Google Docs. JimDo limits the size of files you can upload (500 MB total and 10 MB per file) while Google Sites does not.
JimDo's themes are more modern and attractive than Google Sites' more basic themes. It is easier to create a more visually appealing portfolio using JimDo. Do the templates work on mobile devices?
Here are some of the many resources available for creating a free website. Creating a free account is pretty easy with all of them so you can try a few and get a feel for the differences.
