I'll be upfront and honest, I truly don't have the time to learn SEO. I run a local business, starting another one as well. However, it seems like my rankings are going back down. I read that it's a waste of money to hire someone to do SEO. I run a business in a highly competitive area. If I do look to hire someone, what should I look out for and what should I ask when it comes to their SEO work?
