Could you share your list please. I've had exactly the same question but never found a list specific for communicationsciences. Our university does have a tool that narrows your search down to communication articles. Usually, I just look up the rank on other, more widespread rankings like de SJR. The link below by the way is a rankin of SJR specified to social sciences --> communication.
Thanks, All! We used impact factor, SCIJournal, Google Scholar, and Excellence in Research for Australia. Does anyone have their own university's ranking?
