I read a great article on “LinkedIn Makeover: How to Polish Your Profile” that offered a number of practical suggestions that are not only applicable to a LinkedIn profile but also a CNSV profile:

Photo

• Always use a profile picture.
• Make sure the image is in focus and is cropped closely enough to show your face clearly.
• Consider a context that’s relevant your profession when choosing the setting and background.
• Investing in a professional portrait may go a long way to making a favorable first impression.

Headline

• Customize your headline to encourage people to click through to your profile.
• Consider what sets you apart from others in similar roles.
• Inject personality into your headline.

Profile URL (LinkedIn only)

• If you haven’t customized your URL, it will likely include a string of random letters and numbers.
• Ideally, you want your URL to include your first and last name or company name

Summary

• Inject personality into your summary.
• Avoid littering your summary with overused buzzwords.
• Consider adding words and phrases that hiring managers or potential clients might use to search for someone like you.
• Choose important keywords carefully, and reuse them.

Experience

• Details matter: Be consistent in your use of punctuation, tenses and graphical elements.
• Add data points that showcase the value you bring to companies, such as the amount of money you saved your employer or a client.
