Which can be better for domain name and/or url: hyphen (-), underscore(_), or plus sign(+) provided by seo con?

[Carrie]

The best option is not to use any special character, but if you have to then use ‘-’ because Google bots read ‘-’ as ‘space’. If I say from SEO perspective, say the name you want to use is ‘granny’s apple pie’, so naturally people will search it as ‘granny’s apple pie’ and not ‘granny’s_apple_pie’ or ‘granny’s+apple+pie’. If you use ‘-’ for Google it will be closest to the key phrase ‘granny’s apple pie’.

Hope I was able to explain it clearly. If you need to know anything else please let me know.
