So you have your project set - that’s great!
If you wish to add some words that MUST or CANNOT show in your results - then you need to go Project Settings and set either:
Required keywords - if you want to make Brand24 search for mentions that cover both - your keyword and the phrase(s) next to it
so you’ll get mentions covering Tesla and Ellon and Musk
Excluded keywords - if you want to make Brand24 look only for mentions that cover your keyword but do not contain any of the excluded one(s)
so you’ll get mentions about Tesla but this time, without Ellon and Musk.
And if you want to add more keywords in either of those fields - please remember about commas!
