keywords are good but the combination is not so goodhard to sell for realestate agents or companies.
but in environmental studies, agriculture, and zoning services, they use the term "Land Used" ic. Example: "Total Land Used for Solar Farms in 2023." A company that seells data, historical maps, or environmental impact reports could use this.
it's a narrow niche to be honest
i would say BIN 500
you might make a better number with outbound
Good luck
