Yelp is a very dangerous way to advertise your business. They filter out really positive reviews so no one can see them, but they can leave in negative ones. No matter how legitimate the positive reviews may be, Yelp filters out 5-star reviews if the reviewer is not a very frequent reviewer / member. So Yelp is slanted toward people who review many businesses. If you're not a restaurant or other high volume business, you may not get tons of reviews and the people who review you may not be frequent Yelp reviewers. Yelp will not remove negative reviews, and you can't get them to unfilter the positive ones. If you get lucky with keeping positive reviews, good for you. But Yelp can really hurt your business if you're not careful. They also call you up and hound you to sign-up for expensive paid advertising and a larger profile, but I understand this doesn't help any, and they are completely insensitive to your experience on Yelp. They're money-grubbing, callous people who hide behind the law to protect how their automated filtering "algorithms" can ruin businesses. Be careful creating a profile on Yelp; it can do a lot more harm than good.
