It is not possible to duplicate or merge existing projects in Rank Tracker at the moment.

However you can manually create a copy of an existing project by creating a new project with the same scope:

And then exporting the keywords from your existing project:

And copy or upload them in the new project:

Please note that if you are uploading a list of keywords as CSV or TXT, you remove any columns containing data that is unrelated to keywords or tags.

Historical data for keyword rankings will start on the day you upload them, and will not be copied over from the existing project.
