SEO Help

This may be a dumb question but is it considered black hat to do this:
Say your business is ABC Plumbing and you host your website using the same name. You also own a domain called miamiplumber.com since you live in miami and it redirects to abcplumbing.com. Is that a “no-no” in legit SEO techniques?

Answer #2
