I recently helped a new Twitter user write her bio.
It’s only a few words; however, the process gave rise to challenging questions.
For example, do people read a Twitter bio or do they just scan for keywords like: “mom,” “blogger,” “CEO,” “marketing,” “content,” etc.
If they read the bio, will the same process we use to write adwords copy apply, with the most important ideas first followed by a call to action?
And how do you teach style and attitude? Twitter bios can be short and punchy as well as polished and professional.
While it’s hard to make a generalization, I’m in favor of a keyword-rich, compelling bio with at least one useful link that reveals personality.

Here are 21 things to consider when enhancing your twitter bio.
If you’re happy with yours, this can serve as a checklist.

1. Add a quote.
2. Add a question people should ask you.
3. Add something you are looking for.
4. Add something you can offer.
5. Add your mantra.
6. Add an article that rocks your world.
7. Add a sentence that describes who you are.
8. Add a sentence that describes what you want to do on Twitter.
9. Add descriptive tags, see StumbleUpon for ideas
10. Add a link to people’s replies to you. @Pistachio does this
11. Add your Linkedin account
12. Add your Delicious account
13. Add a link to FriendFeed
14. Add a link to your favorite Flickr photos
15. Add a link to your playlist (blip.fm, last.fm, etc.)
16. Add a link to a YouTube video of you, or that you enjoy watching
17. Add a link another blog, or website you are a part of
18. Cut your bio to 50% its current length
19. Put the most important terms first
20. Decide on your emphasis. If your bio was only one word (and not your name), which word would it be and why?
21.  If you’ve written in a complete sentence, try writing in short, punchy phrases. If you’ve written in short punchy phrases, try writing in complete sentences. Use what works.
