Are Professional LinkedIn Profile Writers Worth It?

[adamyoungg]

I've been updating my job applications recently and realised my LinkedIn profile doesn't reflect my experience very well. While searching for professional LinkedIn profile writers, I found that many services also optimise profiles with relevant keywords and improve the overall presentation for recruiters.
Has anyone here used a professional LinkedIn writing service? I'd be interested to hear whether it made a noticeable difference in profile views, recruiter responses, or interview opportunities.
