LinkedIn tools for posts, bios, and landing pages
LinkedIn rewards a specific first two lines and a readable body. Draft captions here, then rewrite them in a professional voice. Bios and headlines should say who you help, not a string of job titles.
When a post sends traffic to your site, check readability and UTM tags so you know which posts earned visits. Image sizes still matter — a cropped face in a link preview looks careless.
