Skill tags are how Upwork categorizes your profile and matches you to the right searches.
You get 15 slots.
Most people waste them on vague terms that no client is actually searching for. Used correctly, your skill tags put you in front of the right clients before they even read your bio.
Think about what your ideal client types when they need help — not what your job title is.
Focus on:
1️⃣ The specific service — not just your profession, but what you actually do
2️⃣ The tools you work with — if clients search for them
3️⃣ The outcome or area — think like the client, not like your CV
