First: What do you want to communicate and why?
Are you trying to get a job?
Are you trying to make a repository of knowledge?
Are you just playing around?
Are you making an archive?
High-Quality Writing – Communicating effectively is highly-sought-after in business
Ease of Navigation (especially for personal websites)
Don’t clickbait (unless you’re trying to get a job at a clickbait news website)
Projects you’re proud of
Projects you’ve failed at, but learned something and can communicate those learnings
Open-Source contributions (even if this is just documentation-related, that counts)
Stack Overflow profile (if you’re proud of your scores)
