I'm currently doing online chess lessons and have people in my city visit my website to hire me.
People find me when they google 'chess tutoring atlanta'. I would like to expand my online lessons to other cities. As such, I'm thinking of buying multiple domains to target los angeles, miami and NY. Each URL would have the keyword: chess tutoring --insert city.... DOT COM.
I would like all these URLS to point to the same domain. I have two questions
1) Can I have these multiple URLS point to one website or do I need multiple hostings accounts with individual websites?
2) Does google penalize this practice?
