WebmasterWorld does it again, provides answers by reputable sources to questions that plague search engine marketers. So we have about three "local" products by Yahoo!, Yahoo! Yellow Pages, Yahoo! Local and Overture Local Match. What does what, who offers what and how does it help me?
OvertureRep's second post at WMW provides a clear answer:
Yahoo! Yellow Pages consists of a comprehensive database of listings licensed from InfoUSA plus a section of paid listings in the Sponsored Businesses section. The Sponsored Businesses section consists of paid listings from our reseller partners, self-service, and Overture. The Overture products are geographically targeted Local Match and Precision Match listings.
Yahoo! Local also includes a comprehensive database of listings licensed from InfoUSA, several other data sources, and web content. Yahoo! Local also has a sponsored business section which solely consists of geographically targeted Overture Local Match and Precision Match listings.
Overture Local Match is a product for advertisers that have a physical storefront or service a specific geographic region. Advertisers provide a description and details about their business and do not need a website to participate. The advertiser chooses the relevant keywords and defines the geographic region to target their listing.
