I am attempting to grasp the process of optimizing landing pages for local search. For instance, when someone in Chicago searches for a service like "plumber," platforms like Yelp display pages such as "Top 10 Plumbers in Chicago." I'm puzzled about how these pages are created without apparent geographic or business type indicators in the content or metadata. What optimizations are being implemented to make Google recognize that these pages are specific to a particular city and type of business?business
