Always upload a professional photo, ideally a portrait...your clothing is professional. When recruiters or companies check your profile, the photograph may be the first thing they notice.
Keep your LinkedIn profile relevant and concise. Most recruiters scan through profiles for salient points, so keep paragraphs short (3-4 lines), add bullet points, and share examples of success relevant to the job you're seeking.
You don't need to add every skill you have to your LinkedIn profile. Add only the skills relevant to your current job search. Adding irrelevant skills decreases the chance of recruiters finding and reading your profile.
