Use a search engine to locate websites that have mixtape hosting services. Some sites, such as DatPiff, have a better reputation than others. Yet if you cannot afford the fees associated with hosting on a better-known site, use a free service instead. Free hosting sites are equal across the board in terms of reputation, so choose according to their service terms.
Create a membership account with the site you choose. Doing so will ensure that you can log in at any time and modify any preferences related to your mixtape. Before you upload any music, read the fine print to make sure that no copyright clauses will interfere with your rights to your own music. If you're unsure, seek legal advice or proceed at your own risk.
Upload your mixtape track by track. Once it's been submitted, you won't have a chance to make changes to the mixtape, so take your time and choose tracks wisely.
Send the link to the webpage where your mixtape is hosted, such as "Datpiff.com/mysummermixtape" to friends and family. Also, publish the link on your social networking profiles so that others will have an idea of where to find the music you've created.
