Optimizing your online directories and citations is essential for local SEO success. Map data aggregators like Express Update, Neustar Localeze, Foursquare, and Factual provide map data for major platforms like Apple, Yelp, Bing, and Google. Consistency is key across these directories to avoid discrepancies in your business information. Ensure accurate and consistent listings across these platforms, and make sure to remove any duplicate listings you find. Consider getting a Chamber of Commerce membership to gain external inbound links specific to your local area.
