When creating a local listing for your business in search engines like Google, Yahoo!, Best of the Web, and Bing, you will be prompted to choose two to ten categories that describe your business. This is an incredibly important step. Local SEO experts cited proper category associations as the most important signal of relevance. Search engines use category data to determine which businesses to show for particular searches. In the early days of local SEO, Yahoo! Local's Shailesh Bhat provided a very sound explanation of the function of categorization: "In cases where we do not have a self-serve listing, where the merchant has not provided any data, but we have data from other sources, we essentially look out for the degree of agreement between various sources. That is one heuristic element that helps us in figuring out the right category."
