Why Open Graph images matter

When someone shares your blog post on X, LinkedIn, or Slack, the link preview pulls your OG image. A clear title and branding can double click-through rates compared to a generic or missing preview. For indie developers publishing technical content, a consistent OG style also makes your blog look professional across every share. Need the markdown header first?
