About Search Results

YP - The Real Yellow PagesSM - helps you find the right local businesses to meet your specific needs. Search results are sorted by a combination of factors to give you a set of choices in response to your search criteria. These factors are similar to those you might use to determine which business to select from a local Yellow Pages directory, including proximity to where you are searching, expertise in the specific services or products you need, and comprehensive business information to help evaluate a business's suitability for you. “Preferred” listings, or those with featured website buttons, indicate YP advertisers who directly provide information about their businesses to help consumers make more informed buying decisions. YP advertisers receive higher placement in the default ordering of search results and may appear in sponsored listings on the top, side, or bottom of the search results page.
