Start by creating or refining your X (Twitter) profile to establish credibility. Use a professional headshot or logo as your profile picture, craft a bio that clearly states who you help and the value you provide (e.g., 'Helping SaaS founders get leads via X strategies | Free audit DM'), add a header image showcasing a success story or offer, and include a link to a landing page or Gumroad for your product. Pin a thread introducing your expertise and a free resource.
