Your name should be:
1 - easy to say
2 - easy to spell
3 - easy to read
4 - easy to remember
5 - no hyphens (-)
5a - In fact a (-) adds one or more syllables to the name depending on how you say it (e.g. dash or hyphen)
5b - If a person types your site-name in a search without the dash (-) hyphen,
(which most people do anyway)
your site-name.com may not show up in the search results at all.

6 - no more then 5 syllables (not including the .com)
Number of syllable examples:
match.com = 1 syllable
google.com = 2 syllables
youandme.com =  3 syllables
plentyofish.com = 4 syllables
foreverinlove.com = 5 syllables
youandmeforever.com = 6 syllables
youandme-forever.com = 7 syllables (if you say dash)
youandme-forever.com = 8 syllables (if you say hyphen)

7 - available domains: .com, .net, .org

7a- As in the site_name.com,  site_name.net, and site_name.org all belong to you,
to help prevent top-level domain name copy-cat sites.

7b- Also, if you register all three domains at the same time you will not need to worry about
someone else getting them and then trying to sell them to you for thousands of dollars.

7c - One last point on registering .com, .net and .org at the same time.
Let's say someone types your site-name in a search engine without the .com, .net or .org
(which most people do anyway)
Your site may be the 5th or 9th site from the top even though the searcher typed in your site-name.
Because someone registered the same site-name.com before you.

The bottom line, select your website name very carefully and try to be original.
