When it comes to locating a mobile business, several factors need to be considered to ensure its success. Here are some of the best places to consider for your mobile business: 

1. Busy City Centers: Setting up your mobile business in busy city centers can offer high foot traffic and exposure to a large customer base. People often frequent these areas for shopping, dining, and entertainment, making them ideal for a mobile business.

2. Business Districts: Business districts attract a steady stream of professionals and office workers during weekdays. Consider positioning your mobile business near these areas, offering convenient services or products to busy professionals during their lunch breaks or after work.

3. Parks and Recreation Areas: Parks and recreation areas are popular gathering spots, especially during weekends and holidays. A mobile business in these locations can cater to families, joggers, cyclists, and individuals enjoying outdoor activities.

4. Event Venues and Festivals: Positioning your mobile business near event venues, stadiums, or festival grounds can be a profitable strategy. These locations attract large crowds and provide opportunities to serve event-goers with food, beverages, merchandise, or other relevant services.

5. College Campuses: College and university campuses are often bustling with students who require various goods and services. Consider targeting campuses with a mobile business that offers convenience items, snacks, or services catering to student needs.

6. Office Parks and Industrial Areas: Mobile businesses that cater to the needs of office parks and industrial areas can be successful. Employees often appreciate the convenience of on-site services such as food trucks, coffee carts, or mobile salons.

7. Tourist Attractions: If you're in a tourist-heavy area, positioning your mobile business near popular tourist attractions can be advantageous. Tourists are often eager to explore local offerings, including unique food, crafts, souvenirs, or guided tours.

8. Residential Neighborhoods: Depending on the nature of your mobile business, targeting residential neighborhoods can be profitable. This approach works well for services such as mobile pet grooming, laundry services, or food delivery.

Remember to research local regulations, permits, and licensing requirements for operating a mobile business in specific areas. Additionally, market research and understanding your target audience's preferences and needs will help you make an informed decision about the best location for your mobile business.
