Guess first, no penalty. A recruiter (someone who finds people to hire) searches LinkedIn for "data analyst". Which headline is most likely to show up?
LinkedIn is the networking site for work. Recruiters search it by job title, skills and location, so a vague headline and a slow About opening keep you out of their results. A recruiter who needs a data analyst in Bengaluru types a job title and a location into LinkedIn search. The search matches those words against profiles, and your headline is one of the most visible places they can appear.
If your headline says "Open to new opportunities" or "Passionate problem solver", it matches almost no search. Your headline and About section (the summary on your profile) are working text, not decoration. Write them for the search box.
