Defining your salary as "competitive" is worthless since everyone does it (although I saw a job description with "salary: decent" once :) ).
Clearly, being open about the salary gives you a big advantage, applicants know what they can expect and are more willing to spend time going through your interview process. When dealing with recruiters, I only answer their cold email if the salary is listed (among location, company name, tech stack).
One note of caution: if you advertise a range (e.g. 90k to 120k) you should have clear criteria in mind to decided what to offer in your range. As a candidate, I would want to understand why I'm offered 95k instead of 110k for example.
