Write a LinkedIn Headline That Gets Noticed

Act as a LinkedIn headline and search optimisation specialist. I want to rewrite my LinkedIn headline to attract [TARGET_AUDIENCE] and stand out from the crowd. My current headline is [CURRENT_HEADLINE] and my professional role is [YOUR_ROLE]. Write 5 LinkedIn headline variations: outcome-led (what I help clients achieve), problem-led (the pain I solve), credibility-led (achievement or number), niche-specific (narrow audience, clear service), and curiosity-led (makes them want to read more). Each under 220 characters. Rank them by click-through and searchability, and explain which to use for different goals.
