SEO for Local Directories

[John Tabita]

We are adding content to our local directory site. We have pages that contain various types of listings, like community events, golf courses, government offices, etc.

The META data has the city and state (e.g., Delaware OH). But the individual listings only have the city, not the state or zip code.

If the META data contains the city and state, is it necessary that each individual listing also specify the state and zip code? Or is Google smart enough to associate the META data with each listing on that page?

Thanks!
